Review of Vibe X2 - a sandwich smartphone from Lenovo. Lenovo VIBE X2 - a powerful and stylish smartphone Battery life
Lenovo Vibe X2 is a stylish and compact 5-inch smartphone. The dimensions of the device are 140×69 mm, the thickness of the case in some places reaches 7.6 mm. It is comparable in size to the Huawei Honor 6, but the Honor 6 is slightly thicker. The Vibe X2 weighs 121 grams, lighter than the 4.7-inch iPhone 6 (128 grams) or the 4.6-inch Sony Xperia Z3 Compact (128 grams). As you can already understand, the smartphone is compact and thin. By the way, the camera lens does not protrude from the body, as is often the case with some popular thin smartphones. Lenovo Vibe X2 fits well in the hand, but using one hand is not very comfortable.
Lenovo Vibe X2 has an unusual original design. The smartphone seems to be assembled from four panels: the top panel is black, the other three layers are multi-colored. If you look at it from the side, it somewhat resembles an “expanded” German flag. In general, it looks unusual; girls will definitely like the appearance of the smartphone. Today, the Lenovo Vibe X2 smartphone can be purchased in white and gold colors. There are also color options, but they are not sold in Russia, at least for now. You can purchase additional accessories for your smartphone: a case, a special speaker and a charger.
The Lenovo Vibe X2 has a plastic body and good build quality, but we noticed that it creaks slightly under pressure. The back is made of smooth plastic that is pleasant to the touch. By the way, after two weeks of use it hardly got scratched.
Screen - 4.3
One of the advantages of the Lenovo Vibe X2 is its good five-inch display. The display resolution is 1920×1080 pixels, high for such a diagonal. The matrix type is IPS, there is an oleophobic (grease-repellent) coating and protective glass Gorilla Glass 3. The pixel density is 441 per inch, this is enough for a clear image on small fonts and icons.
The maximum brightness of the display, in our opinion, is low - up to 328 cd/m2. However, if you switch to the special “High Brightness Mode”, you can get 484 cd/m2, which is already very bright. Another thing is that you need to look for this mode separately in the settings. The minimum white brightness is 5 cd/m2, the display will definitely not be blinding in the dark. This is one of the best adjustable brightness ranges. The display has auto-brightness, we checked its operation - it worked quickly, but only in “hard” mode, without the ability to adjust the brightness ranges using the slider. In the sun, reading the display was difficult, but not critical. The viewing angles of the display are not maximum, but wide enough for comfortable work with a smartphone.
The grease-repellent coating works well. This does not mean that the screen will not get dirty at all: while using the phone, fingerprints remained on the screen, but they did not appear so quickly and were erased.
Camera
The Lenovo Vibe X2 smartphone has 13 MP main and 5 MP front cameras, which are excellent for an “average” smartphone. The main camera is equipped with an LED flash, autofocus, HDR mode, face and smile detection, with the ability to shoot panoramas and much more. Compared to the Lenovo Vibe Z2 Pro, there are fewer settings here, the camera resolution is also lower, but you must agree that the price tag is much more affordable.
The maximum photo resolution is 4160×43120 pixels. The camera shoots Full HD video at 30 frames per second. Audio is recorded in stereo. The camera interface is simple and clear, you won’t have to search for the necessary settings for a long time. Photo quality is good and matches the high megapixel count. The camera copes well with light and even in dark scenes there is not much noise. At the same time, in terms of detail and sharpness it is somewhat inferior to flagship cameras. You can verify this by looking at examples of photos taken on a smartphone. Also, in tests, we were not always able to focus on the desired object the first time, so we recommend doing several takes. It's good that the camera takes pictures quickly.
The phone's 5 MP front camera is enough for video calling and is great for selfies. The camera does not have autofocus or flash. But, as we wrote earlier, at CES 2015 Lenovo introduced a special accessory for the phone - a separate flash for selfies, the Vibe Xtention Selfie Flash. It is not yet available for free sale, and it is unclear whether it will appear. The front camera also shoots Full HD video at 30 frames per second.

Working with text - 3.0
To our surprise, the phone uses a standard Google keyboard. The company is redrawing the interface, but has not yet gotten to the keyboard; even for the flagship Lenovo Vibe Z2 Pro, manufacturers did not draw their own keyboard.
Overall, Google's keyboard is good. When typing text, you can use continuous input. There is a separate key to switch between languages. There are no additional symbols on the icons, only numbers on the top row of keys. Note that in “portrait” mode, typing texts with one hand is realistic and quite convenient.
Internet - 3.0
Google Chrome and Yandex Browser are preinstalled as browsers on the Lenovo Vibe X2 smartphone. The first has support for synchronizing tabs with the desktop version of the browser, the second has a “Turbo” mode for fast loading pages, the ability to close tabs automatically when exiting the browser, etc. If you need a reading mode or automatic text fitting, then you can always download and install another favorite browser. As tests have shown, the smartphone copes well with several open tabs, works quickly and does not slow down.
Interfaces
The Lenovo Vibe X2 smartphone supports all popular wireless interfaces except NFC and infrared. Separately, we note the presence of dual-band Wi-Fi and high-speed Wi-Fi standard (802.11 ac). The smartphone has a Bluetooth module with support for the A2DP profile for audio transmission, the ability to work in Russian LTE frequencies (Cat 4 up to 150 Mbit/s), A-GPS and GLONASS.
The only negative is the slow GPS module; it has a long cold start, which took a couple of minutes. Otherwise, everything functioned smoothly. For a complete flagship set, only NFC is missing. The phone is equipped with a slot for Micro-SIM cards and a Micro-USB connector, but, unfortunately, OTG and MHL are not supported; you cannot connect peripherals or transmit high-definition video via USB.
Multimedia - 3.0
Multimedia capabilities of the Lenovo Vibe X2 can be called average. The smartphone supports common video formats and codecs, plays video in high quality, up to Full HD video. However, in our tests it was unable to run, for example, FLV video. There is no choice of subtitles or audio tracks in the built-in video player, as well as any other settings other than a list with the playback history. The audio player plays popular MP3 and AAC formats, as well as WAV, but does not play AC3 and FLAC (the latter can be launched through the file manager). The smartphone comes pre-installed with the standard Play Music application, which is not the most convenient. The Lenovo Vibe X2 comes with headphones, but, in our opinion, they are of poor quality; for such a price I would like better headphones.
Battery - 2.8
The Lenovo Vibe X2 smartphone is equipped with a 2300 mAh battery. By today's standards, the capacity cannot be called large, so the Huawei Honor 6 has a 3100 mAh battery, although it is only slightly thicker. Formal capacity is not everything; how did the smartphone perform in battery tests? The battery passed our tests well, the results are comparable to the LG Nexus 5 battery (same 2300 mAh). The Lenovo Vibe X2 phone played HD videos at maximum brightness for about 6 and a half hours, which is not bad. I lasted “only” 43 hours in music listening mode. If we compare it with the Nexus 5, the latter drained faster in the video test, but took longer in the music player mode.
As for daily use, it was enough for a day and a half, but it didn’t last up to a day and a half. Note that the smartphone has quite extensive “power” settings - emergency mode (only calls and SMS messages are available in it), disabling applications in sleep mode, saving energy for the screen, etc.
The smartphone comes with a 1.5 A charger.
Performance - 3.9
The device uses the MediaTek MT6595m True8Core platform, as the name suggests, eight-core - four cores at 1.7 GHz and four cores at 2 GHz. PowerVR G600 is responsible for graphics, the amount of RAM is 2 GB. The performance of the smartphone is at the highest level, the “filling” is one of the most productive today; in our tests it coped well with heavy games and benchmarks. Thanks to shell optimization and powerful hardware, the Lenovo Vibe X2 smartphone works quickly, and this applies to both built-in applications and third-party programs. The phone can be considered as a gaming platform; in our tests, the games NOVA 3, Dead Trigger, Minion Rush and Asphalt 8 loaded quickly and ran smoothly even at maximum settings. In daily use, the smartphone worked quickly.
In benchmarks, the Lenovo Vibe X2 smartphone showed high, flagship results. In the AnTuTu benchmark, it received scores comparable to those of the Sony Xpeira Z3 Compact - 45400 points, and in Ice Storm Unlimited from 3DMark it was slightly lower - an average of 12243 points.
Memory - 2.5
The built-in memory capacity of the Lenovo Vibe X2 smartphone is 32 GB, of which approximately 26.2 GB is available to the user - this amount of memory is enough for most users. Like many smartphones in the line, there is no slot for a memory card and this is a significant disadvantage of the phone.
Peculiarities
The Lenovo Vibe X2 smartphone runs on Android 4.4.2 OS and Lenovo's proprietary shell. The manufacturer plans to update the OS to Android Lollipop in mid-2015. The appearance of the system interface has been changed, the dialer has been redrawn, the launcher has been replaced, etc. It’s a little unusual that there is no separate menu with a list of all applications. The smartphone also has separate “special” settings, where a lot of interesting things are hidden. For example, displaying a “smart menu” button with quick access to a number of applications, “waking up” the display with a double tap, a gesture to launch the camera, and much more.
The main feature of the smartphone is its unusual design. Due to the thin layered body, Lenovo Vibe X2 looks fresh and unusual. Also among the features we name support for high-speed Wi-Fi 802.11 ac, LTE, and glove mode.
Slim model with an unusual design on the latest eight-core platform with LTE support
Over the past year, we have observed how Chinese smartphone manufacturers have been introducing a new eight-core SoC called Mediatek MTK 6592 into their top (and not only) mobile products. This hardware platform is based on the operation of as many as eight full-fledged processor cores. True, these cores are not very powerful (ARM Cortex-A7), and therefore, despite all the expectations of supporters of cheaper Chinese products, the platform was not able to shine. In terms of this indicator, it is surpassed by the modern quad-core SoC Qualcomm Snapdragon 800/801, on which the operation of top-end devices from world-class brands is based. And with the battery life of mobile devices on the Mediatek platform, things are quite deplorable, although good optimization by specific manufacturers can work wonders here too. A striking example of this is the TCL (Alcatel) Idol X+, excellent in all respects, which is still almost a reference example of what a modern top-end Chinese smartphone should be, both in terms of characteristics and external data.
Today we see how the first eight-core smartphones are gradually being replaced by a new wave of devices based on a completely new SoC from the same manufacturer. Also eight-core, it becomes a logical and improved continuation of MTK 6592. The newest Mediatek platform is called MTK 6595, and it has even more differences from MTK 6592 than it might seem at first glance. Mediatek MTK 6595 not only became the long-awaited SoC that finally supports full operation with LTE networks, but it also has deeper, structural changes. Unlike its predecessor, all eight cores of which were equivalent, it uses a more logical big.LITTLE technology, where four powerful cores are adjacent to four less productive, but more economical ones. Literally all well-known mobile SoC manufacturers from Samsung to Huawei have already adopted this technology for their mobile platforms. By the way, the release of eight-core SoCs with a similar structure from Qualcomm itself is not far off (we even managed to get acquainted with one of the first devices based on such a platform - Oppo R5). So in the new season we will witness another round of confrontation between two industry giants, MTK and Qualcomm, because already now many of the largest smartphone manufacturers in China, such as Lenovo and Xiaomi, are voting for cooperation with Mediatek, that is, we are talking about huge production volumes .
So, one of the first devices based on the latest Mediatek MTK 6595 platform was the Lenovo Vibe X2 smartphone, which has already begun to be sold not only in China, but also here. The smartphone is somehow invisibly but persistently reminiscent of the same TCL (Alcatel) Idol X+ mentioned above, adjusted for the new SoC and changing fashion trends. Equally unusually compact and lightweight, very thin and stylish, the Lenovo Vibe X2 smartphone is ready to offer, among other things, unprecedented performance that can be the envy of any modern flagship device from generally recognized market leaders. At the same time, the device is offered at a much more reasonable price than top-end devices from A-brands, which makes the choice in favor of the Idol X+ and Vibe X2 even more justified. The Lenovo Vibe X2 smartphone turned out to be very interesting, at this price it is quite capable of gaining great popularity among users, so it’s time to take a closer look at the new product.

Contents of delivery
A stylish smartphone with a bright and unusual design comes on sale in an equally unusual and remarkable packaging. The box itself is quite small, made entirely of hard, high-quality cardboard, and its structure is unusual. From the side end of the cardboard shell, two different-sized drawers pull out laterally, independently of each other, in the manner of a chest of drawers. For finger gripping, a silk ribbon is glued to the side surface of the box, and the boxes themselves are painted in different colors in such a way as to replicate the similar multi-colored multi-layer structure of the body of the smartphone itself. Among other things, this entire structure is also covered with an additional cover on top - a dust jacket made of soft cardboard, which has long become a signature feature of the packaging of modern top-end Lenovo smartphones. In general, the Lenovo Vibe X2 box is beautiful and unusual, complex in structure, and due to its design, it is a logical continuation of the “multi-layered” style that the developers chose for their new smartphone.
Inside the drawers, in several compartments, there is a standard set of accessories: a universal charger (5 V, 1.5 A), a Micro-USB connecting cable, as well as a wired stereo headset with a flat, tangle-free wire and vacuum-type rubber ear pads. But that is not all. A special sticker pasted on the outside of the box forces you to dig deeper into the numerous compartments in search of additional “goodies.” Even despite the low cost, Lenovo was not greedy in equipping its stylish product with additional protective accessories: in one of the cardboard boxes with documentation, a plastic case and a film for the screen were unexpectedly discovered. The case is so transparent that it remains almost invisible when put on the smartphone, and does not in the least obscure the unusual bright design of the device itself. The key for removing the SIM card is traditionally attached to the wall of a cardboard box with paper documentation.
In general, the Lenovo Vibe X2 packaging and its contents are presented so aesthetically that they immediately create the most favorable mood for further acquaintance with the product.
Appearance and ease of use
The design of the new product is completely different from any of the previous Lenovo devices. The smartphone has an unusual image, the body seems to be assembled from several layers. Moreover, these layers have different colors, varying depending on the main color of the case, which is determined by the color of the back wall.
That is, if we are talking about a gray body, then various shades of gray prevail in these layers, in golden layers there are shades of red and pink, in red layers burgundy stripes are visible, and so on. In total, several different color options have been launched into production, but deliveries of three of them are planned for the Russian market: gray, red and golden (this color is shown in our photographs).
Such an unusual find in design significantly affects the perception of the device, making it much more interesting and attractive, because in general there is absolutely nothing unusual in the structure or materials of the Lenovo Vibe X2 case.
The body is made not of metal, but of plastic, and in shape it is a completely ordinary “plank” with straight edges, flat surfaces and fairly sharp edges. Due to its not very large dimensions and thin thickness, the smartphone can be carried quite comfortably even in a trouser pocket.
The size of the device is really very small; for a large five-inch display, the dimensions of the device are almost record-breaking. The weight is also significantly less than most modern large-diagonal models, and due to the matte surfaces, the smartphone fits perfectly in the hand, does not slip and does not collect fingerprints.
Since the case has a monolithic, non-separable structure, the appropriate method for installing the SIM card is used here: the card slides into the side slot on a metal slide, to remove which you need to use the supplied key-clip. The device supports working with one SIM card in Micro-SIM format, but there are rumors that there is also a modification of the smartphone with two SIM cards; this option is simply not provided for our market.
The camera module and a single LED flash are embedded flush with the surface of the back cover, none of the elements protrude outward. The camera window is framed by a metal ring; the flash can act as a flashlight using a built-in program.
At the bottom of the back cover there is a speaker grille made in the form of an array of small round holes. When the phone is placed on a hard surface, the sound is almost completely blocked due to the absence of any protrusions on the back of the case.
Nearby you can see an open group of contacts for connecting accessories, such as a case with an additional battery. This case is made in the same style as the mentioned protective kit, its walls are the same transparent, so as not to cover the most important advantage of the case - its multi-layered appearance. It turns out that the additional battery adds another layer at the back, which generally fits into the unified concept of this typesetting design; in this regard, the developers thought through everything well.
The front part of the case is completely covered with flat protective glass Gorilla Glass. In the upper part of the glass there is a slot cut out for the painted metal grille of the speaker; the eyes of the sensors and the front camera are visible nearby. In the right corner there is an LED status indicator, shining with a small dim dot and signaling the charging status and incoming messages. There is a special item in the settings menu to regulate the indicator’s operation.
The touch buttons at the bottom of the front panel have a dim white backlight with an adjustable glow time; there is also a special item for this in the settings.
Both mechanical control buttons are located on the same right side. The power button and volume key are made of metal, they are not streamlined, have sharp edges and straight edges, and are quite easy to find blindly. The keys are not very pleasant to the touch, and their travel is also quite short and hard.
At the bottom end there is a universal Micro-USB connector, next to the main microphone hole. Unfortunately, the mode for connecting external devices to the USB port (OTG) is not supported here.
The universal 3.5 mm headphone output jack is located alone at the top end; there are no other elements here. The connectors of the device are not covered with plugs, and there are no fastenings for the strap on the case. The device does not receive protection from water and dust, nor does it support wireless charging.
Screen
Lenovo Vibe X2 is equipped with an IPS touch matrix protected by Corning Gorilla Glass 3. The screen dimensions are 62x110 mm, 5-inch diagonal, resolution - 1920x1080 pixels (Full HD). Accordingly, the dot density reaches 440 ppi - this is a very high, although not a record figure.
The thickness of the side frames from the edge of the screen to the edge of the body is about 3 mm, the top and bottom are about 15 mm. The frames are narrow, the developers managed to fit a large five-inch display into fairly comfortable dimensions of the case.
The display brightness can be adjusted manually, or you can use automatic adjustment. Multi-touch technology here allows you to process 10 simultaneous touches. When you bring the smartphone to your ear, the screen is locked using a proximity sensor. The screen, among other things, can be activated by double tapping the glass; additional protection is provided against accidental unlocking in a pocket or bag.

A detailed examination using measuring instruments was carried out by the editor of the “Monitors” and “Projectors and TV” sections Alexey Kudryavtsev. Here is his expert opinion on the screen of the sample under study.
The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface that is scratch-resistant. Judging by the reflection of objects, the anti-glare properties of the screen are no worse than those of the Google Nexus 7 (2013) screen (hereinafter simply Nexus 7). For clarity, here is a photograph in which a white surface is reflected in the switched off screens (on the left - Nexus 7, on the right - Lenovo Vibe X2, then they can be distinguished by size):
The Lenovo Vibe X2's screen is slightly darker (brightness according to photographs is 99 versus 102 for the Nexus 7). The ghosting of reflected objects in the Lenovo Vibe X2 screen is very weak, this indicates that there is no air gap between the layers of the screen (more specifically, between the outer glass and the surface of the LCD matrix) (OGS - One Glass Solution type screen). Due to the smaller number of boundaries (glass/air type) with very different refractive indices, such screens look better in conditions of strong external illumination, but their repair in the case of cracked external glass is much more expensive, since the entire screen has to be replaced. On the outer surface of the screen there is a special oleophobic (grease-repellent) coating (effective, maybe a little worse than that of the Nexus 7), so fingerprints are removed much easier and appear at a lower speed than in the case of regular glass.
With manual brightness control and when the white field was displayed in full screen, the maximum brightness value was about 435 cd/m², the minimum was 5.8 cd/m². The maximum brightness is quite high, and, given the excellent anti-glare properties, readability even on a sunny day outdoors could be at a good level, but, unfortunately, this is not the case, why - see below. In complete darkness, the brightness can be reduced to a comfortable value. There is automatic brightness adjustment based on the light sensor (located to the right of the front camera). In automatic mode, when external lighting conditions change, the screen brightness both increases and decreases. In complete darkness, the auto-brightness function reduces the brightness to 14 cd/m² (a bit dark, but you can read), in an office illuminated by artificial light (approximately 400 lux) it is set to 140 cd/m² (suitable), in a very bright environment (corresponding to lighting on a clear day outdoors, but without direct sunlight - 20,000 lux or a little more) increases almost to the maximum - up to 420 cd / m². As a result, the auto-brightness function works absolutely adequately. Additionally, in the screen settings you can enable the high brightness mode, in this case we got about 610 cd/m². At any brightness level, there is virtually no backlight modulation, so there is no screen flickering.
This smartphone uses an IPS matrix. The microphotographs show a typical IPS subpixel structure:
For comparison, you can see the gallery of microphotographs of screens used in mobile technology.
The screen has good viewing angles without significant color shift even with large viewing deviations from perpendicular to the screen and without inverting shades. For comparison, here are photographs in which the same images are displayed on the screens of Lenovo Vibe X2 and Nexus 7, while the screen brightness is initially set to approximately 200 cd/m² (over a white field in the entire screen), and the color balance on the camera is forcibly switched to 6500 K . White field perpendicular to the screens:
The uniformity of brightness and color tone of the white field is average, since towards the bottom of the screen (to the right in the photo above) the brightness increases significantly. And a test picture (here the brightness of the Lenovo Vibe X2 screen had to be adjusted to visually match the brightness of the Nexus 7):
Color reproduction is good and colors are rich on both screens. Now at an angle of approximately 45 degrees to the plane and to the side of the screen:
It can be seen that the colors have not changed much on both screens, but the contrast on the Lenovo Vibe X2 has decreased to a greater extent due to greater black brightening and a decrease in brightness. And a white field:
The brightness of the screens at an angle decreased (by at least 5 times, based on the difference in shutter speed), but in the case of the Lenovo Vibe X2 the drop in brightness is slightly greater. When deviated diagonally, the black field brightens greatly and acquires a slight purple or red-violet tint. The photographs below demonstrate this (the brightness of the white areas in the direction perpendicular to the plane of the screens is approximately the same!):
And from another angle:
When viewed perpendicularly, the uniformity of the black field is not ideal; closer to the buttons, where the backlight LEDs are apparently located, the black color is noticeably brightened:
The contrast (approximately in the center of the screen) is good - about 860:1. The response time for the black-white-black transition is 15 ms (9 ms on + 6 ms off). The transition between halftones of gray 25% and 75% (based on the numerical value of the color) and back takes a total of 21 ms. The gamma curve, constructed using 32 points with equal intervals based on the numerical value of the shade of gray, did not reveal any blockage in either the highlights or the shadows. The exponent of the approximating power function is 3.06, which is significantly higher than the standard value of 2.2. In this case, the real gamma curve deviates very strongly from the power-law dependence:
Due to the dynamic and very aggressive adjustment of the backlight brightness in accordance with the nature of the output image (in dark areas the brightness decreases), the resulting dependence of brightness on hue (gamma curve) does not correspond to the gamma curve of a static image, since the measurements were carried out with sequential output of shades of gray almost in full screen. For this reason, we carried out a number of tests - determining contrast and response time, comparing black illumination at angles - when displaying special templates with a constant average brightness, and not monochromatic fields in the entire screen. In general, this non-disabled brightness correction does nothing but harm, since constantly changing the screen brightness can at least cause some discomfort and reduce the visibility of gradations in the shadows in the case of dark images. In this case, the manufacturer has surpassed all others, since this dynamic adjustment, when displaying any image other than a white field on the entire screen, significantly reduces the brightness, which significantly reduces the readability of the screen in bright light.
The color gamut from a practical point of view is equal to sRGB:
The spectra show that the matrix filters moderately mix the components with each other:
As a result, visually the colors have a natural saturation. The balance of shades on the gray scale is good, since the color temperature is slightly higher than the standard 6500 K, and the deviation from the blackbody spectrum (ΔE) is less than 10, which is considered a good indicator for a consumer device. At the same time, color temperature and ΔE change little from hue to hue - this has a positive effect on the visual assessment of color balance. (The darkest areas of the gray scale can be ignored, since color balance there is not very important, and the error in measuring color characteristics at low brightness is large.)
In this smartphone, in the screen settings, you can select a high brightness mode, set the option Extended outdoor mode(but there is no noticeable effect from it on the street as well), turn on some Adaptive mode, in which increasing the yellowness of the screen supposedly reduces eye fatigue, and also switch to manual mode, in which you can adjust the color tone, saturation (color contrast) and simply contrast. An example of what we got when we tried to adjust the color balance is shown in the graphs above in the form of dependencies labeled as Corr. After the correction, the color balance improved slightly, but not significantly. There is no particular need to intervene.
Let's summarize. Formally, the screen has a fairly high maximum brightness (even without additional amplification) and has good anti-glare properties. However, dynamic adjustment of the backlight brightness greatly reduces the brightness when displaying any image other than a full-screen white field, which significantly reduces readability in conditions with bright ambient lighting. The high-brightness mode helps somewhat, but it will have to be turned on manually. In complete darkness, the brightness can be reduced to a comfortable level. It is also possible to use a mode with automatic brightness adjustment, which works adequately, but does not compensate for the above-mentioned features. The advantages of the screen include an effective oleophobic coating, the absence of flicker and air gaps in the layers of the screen, as well as the sRGB color gamut and good color balance. Significant disadvantages include, first of all, the extremely aggressive non-switchable dynamic adjustment of the backlight brightness and the low stability of black to the deviation of the gaze from perpendicular to the screen plane. Both of these shortcomings (especially the first) no longer allow us to assign the screen a “high quality” rating - it is, in the end, average.
Sound
The Lenovo Vibe X2 has only one main speaker; it produces a fairly loud and ringing sound, clear throughout the entire spectrum, but practically devoid of low frequencies. The sound output grille here is cut into the back wall, so the sound is significantly muffled when the device is lying on the table. In conversational dynamics, the voice of a familiar interlocutor, timbre and intonation remain recognizable, the conversation is quite comfortable.
To play music, there is only a standard Google Music player with a minimum number of settings in the form of preset equalizer values.
An FM radio is included as standard with the smartphone, and there is also a voice recorder. The device can also record telephone conversations from the line; to do this, just press a special button in the telephone application interface right during a call.

Camera
Lenovo Vibe X2 is equipped with two digital camera modules with a resolution of 13 and 5 megapixels. The front 5-megapixel camera has a fixed focus, pictures are taken in size 2560x1920. You can initiate taking a “selfie” here in various ways: using gestures, voice commands and even blinking your eyes, but simply pressing the hardware sound key cannot release the shutter of the front camera, and this is one of the most convenient ways. In the settings, it is possible to assign shooting to this hardware key, but this only works in the case of the rear camera.
The main rear camera is equipped with a 13-megapixel module with f/2.2 aperture, autofocus and a single LED flash. There is no optical stabilization here, just as there is no ability to shoot 4K video or at 60 fps. The camera's capabilities are quite simple, although in good lighting it takes quite tolerable quality pictures.
The camera control menu is also very simple in its capabilities and interface. In addition to the usual shooting mode, there is a panoramic and HDR mode, plus you can use some additional effects.

The camera can shoot video in the maximum Full HD resolution (1920×1080, 30 fps). An example of a test video is presented below.
- Video No. 1 (84 MB, 1920×1080, 30 fps)
 |
The camera copes well with shooting text. |
 |
The camera does macro photography well, but fine details are lost in the noise. |
 |
The field and plane sharpness is quite good. |
 |
Quite large areas of out of focus can be seen at the bottom and left of the frame. |
 |
The camera handles close-ups well, although the noise reduction could have been softer. |
 |
Bad shots also happen. Judging by the relatively short shutter speed, the autofocus was wrong. |
The camera turned out to be not outstanding at all, especially for its 13 megapixels. The sensor may not be so weak, but the noise reduction still processes it quite roughly, which is why details are lost, especially in the shadows, even in weak ones. Sometimes failures occur in the form of large areas of blur or autofocus errors. However, in most cases the pictures come out good. The sharpness in shots is good and decreases quite smoothly, and in good lighting it will probably be even better. In general, the camera does not do too bad and is quite suitable for documentary shooting.
Telephone and communications
The smartphone works as standard in modern 2G GSM and 3G WCDMA networks, and also supports fourth generation LTE networks. In practice, with a SIM card from the domestic operator MTS, the smartphone confidently recognizes and works with 4G networks. The network capabilities of the smartphone are not the richest, but they meet the minimum modern requirements: there is support for Wi-Fi 802.11b/g/n/ac, both bands (2.4/5 GHz), as well as Bluetooth 3.0 + 4.1 LE. Wi-Fi Direct and Wi-Fi Display are supported; as a standard, you can organize a wireless access point via Wi-Fi or Bluetooth channels. At home, with the Asus RT-N16 router as an access point, the hero of the review demonstrated a connection speed of 48 Mbit/s. There is no NFC, and there is no support for USB OTG mode either. The navigation module works with both GPS and the domestic Glonass system, the speed of the module is not satisfactory.
 |
 |
OS and software
The device uses the Google Android software platform version 4.4.2 as a system with a graphical user interface installed on top of it called Lenovo Vibe UI. Externally, the shell looks neat, but, traditionally for Lenovo, it is somehow clumsy and therefore unstylish, there are too many different colors. Application icons are flat, there is no separate menu for them - all icons are immediately placed on desktops mixed with widgets.
 |
 |
The settings menu is divided into two sections: one contains most of the usual system settings, and the second is devoted to specific ones, such as working with gestures, various modes (“in the pocket”, “in the hands”), as well as settings for the proprietary button called Smart Menu . Smart Menu creates a virtual button placed at any edge of the screen. By clicking on this button, a quick access menu to the main functions of the smartphone opens, a set of which can be specified by the user.
Of course, there is no opportunity to reduce the size of the desktop and bring the keyboard closer to the edge - a five-inch screen is no longer considered in the modern world as something out of the ordinary and requires adapting the interface for “one-handed” control.

One thing can be said about pre-installed programs: there are too many of them; This is perhaps one of the disadvantages of Lenovo mobile devices. All this huge number of applications, sorted into numerous folders, consists of completely free, publicly available programs that, if desired, any user can download from the Play Store - but only those that he really needs. It also comes pre-installed with a full set of Yandex mobile applications (free and mostly duplicating Google’s branded applications) and, of course, a full set of clients for the most popular social networks, as well as several games. Branded utility applications have the same endings, they are easy to recognize and guess their purpose by their names: ShareIt, SyncIt, SnapIt Camera, SeeIt Gallery, CloneIt. Security tools are united by the Security program, which includes an antivirus, spam filter, anti-theft program, various data protection modes, parental controls and even the ability to optimize hardware operation.

Performance
The Lenovo Vibe X2 hardware platform is based on the latest Mediatek MT6595m single-chip system (SoC), in which 4 powerful Cortex-A17 cores (2.0 GHz) are adjacent to 4 Cortex-A7 cores (1.7 GHz), less productive, but also more economical. The operation of the new SoC is based on the big.LITTLE principle, while the previous eight-core Mediatek platform had eight low-power equivalent ARM Cortex-A7 cores. The MT6595m is capable of demonstrating the highest performance to date, in which it can compete with the top Qualcomm Snapdragon 801.
Graphics processing in the smartphone is handled by the new PowerVR G6200 GPU video accelerator with 2 cores with a frequency of up to 450 MHz. This is the main difference between the graphics subsystem of the simplified SoC Mediatek MT6595m in comparison with the full Mediatek MT6595, which runs the Meizu MX4. That, in addition to a higher maximum operating frequency of processor cores (up to 2.2 GHz), also has a higher frequency of graphics cores (up to 600 MHz). So it is not surprising that in all test programs, both complex and graphic, the full-fledged Meizu MX4 (MT6595) platform demonstrates better results than the Lenovo Vibe X2 (MT6595m) platform.
The amount of RAM in the Lenovo Vibe X2 is 2 GB, and about 23 GB of the nominally designated 32 GB of internal memory is available for the user’s needs in the device. The amount of internal memory cannot be increased using microSD cards; the smartphone does not support memory cards. Also, you cannot connect external flash drives to the Micro-USB port using a special adapter in OTG mode. That is, the amount of built-in memory is finite, and it cannot be expanded by any means.

According to the results of testing in benchmarks, a smartphone on the new Mediatek platform showed itself to be one of the most powerful and productive modern mobile devices at the moment, coming very close, and in some ways even ahead of the top solutions of generally recognized market leaders based on Qualcomm Snapdragon 801. What is gratifying is that and the new graphics subsystem here is also the most powerful; in game tests it demonstrates not exorbitant, but maximum figures, almost at the level of Adreno 330, although, of course, it is slightly inferior to the latter. Finally, the Chinese have made a truly powerful platform of a decent level, all that remains is to understand how economical it remains at the same time - after all, the previous eight-core MTK 6592 showed very disastrous results in this regard. Currently there are only a few models on the market based on the new platform (Lenovo Vibe X2, Meizu MX4 and Zopo 999), but next season we can expect a large influx of new products based on this SoC.
Testing in the latest versions of comprehensive tests AnTuTu and GeekBench 3:
For convenience, we have compiled all the results we obtained when testing the smartphone in the latest versions of popular benchmarks into tables. The table usually adds several other devices from different segments, also tested on similar latest versions of benchmarks (this is done only for a visual assessment of the obtained dry numbers). Unfortunately, within the framework of one comparison it is impossible to present the results from different versions of benchmarks, so many worthy and relevant models remain “behind the scenes” - due to the fact that they once passed the “obstacle course” on previous versions of test programs.
 |

 |
 |
Testing the graphics subsystem in 3DMark game tests,GFXBenchmark, and Bonsai Benchmark:
When testing in 3DMark, the most powerful smartphones now have the ability to run the application in Unlimited mode, where the rendering resolution is fixed at 720p and VSync is disabled (which can cause the speed to rise above 60 fps).
 |
 |
Browser cross-platform tests:
As for benchmarks for assessing the speed of the javascript engine, you should always make allowance for the fact that their results significantly depend on the browser in which they are launched, so the comparison can only be truly correct on the same OS and browsers, and this is possible during testing not always. For Android OS, we always try to use Google Chrome.

Playing video
To test “omnivorous” video playback (including support for various codecs, containers and special features, such as subtitles), we used the most common formats, which make up the bulk of the content available on the Web. Note that for mobile devices it is important to have support for hardware video decoding at the chip level, since it is most often impossible to process modern options using processor cores alone. Also, you shouldn’t expect a mobile device to decode everything, since the leadership in flexibility belongs to the PC, and no one is going to challenge it.
According to the testing results, the subject was not provided with full support for all the necessary decoders, in this case, audio ones. To fully play most of the most common files on the network, you will have to resort to the help of a third-party player - for example, MX Player. True, even in it you will first have to change the settings, switching from hardware decoding to software or to a new mode called Hardware+(not supported by all smartphones).
| Format | Container, video, sound | MX Video Player | Standard video player |
| DVDRip | AVI, XviD 720×400 2200 Kbps, MP3+AC3 | plays normally | plays normally |
| Web-DL SD | AVI, XviD 720×400 1400 Kbps, MP3+AC3 | plays normally | plays normally |
| Web-DL HD | MKV, H.264 1280×720 3000 Kbps, AC3 | Hardware+ | |
| BDRip 720p | MKV, H.264 1280×720 4000 Kbps, AC3 | plays fine with decoder Hardware+ | The video plays fine, but there is no sound¹ |
| BDRip 1080p | MKV, H.264 1920×1080 8000 Kbps, AC3 | plays fine with decoder Hardware+ | The video plays fine, but there is no sound¹ |
¹ MX Video Player only played sound after switching to software decoding or a new mode Hardware+; The standard player does not have this setting
Further testing of video playback was performed Alexey Kudryavtsev.
We did not find the MHL interface, like Mobility DisplayPort, in this smartphone, so we had to limit ourselves to testing the output of video files on the screen of the device itself. To do this, we used a set of test files with an arrow and a rectangle moving one division per frame (see “Methodology for testing video playback and display devices. Version 1 (for mobile devices) 720/24p
Note: If in both columns Uniformity And Passes green ratings are given, this means that, most likely, when watching films, artifacts caused by uneven alternation and frame skipping will either not be visible at all, or their number and visibility will not affect the viewing comfort. Red marks indicate possible problems with playback of the corresponding files.
According to the frame output criterion, the quality of playback of video files on the screen of the smartphone itself is good, since frames (or groups of frames) can (but are not required) be output with uniform alternation of intervals and without skipping frames. The smartphone can even display files with a resolution of 4K up to 30 fps inclusive. When playing video files with a resolution of 1920 by 1080 (1080p) on a smartphone screen, the image of the video file itself is displayed exactly along the border of the screen, one to one in pixels, that is, in the original resolution. The brightness range displayed on the screen corresponds to the standard range of 16-235 - almost all gradations of shades are displayed in shadows and highlights (the hue difference in shadows and highlights can be ignored) - which is what is required for correct playback of typical video files.
Battery life
Lenovo Vibe X2 does not have the largest battery on the modern mobile market - 2300 mAh. The problem is that the body of the smartphone is too thin to accommodate a larger battery, so you have to make do with what you have if you want a sleek, thin smartphone. The new powerful hardware platform on which the hero of the review is based also makes its own adjustments: the smartphone, as expected, turned out to be quite power-hungry, in active mode its charge will last for half a day, in normal mode - for a day, no more. At the same time, quite strange differences in the stability of energy consumption are observed. For example, while showing quite average figures for battery life in reading and 3D gaming modes, the device demonstrated completely disastrous results when playing a 720p video over a home Wi-Fi network using a third-party application - the MX player. Obviously, we are talking about poor optimization here, and perhaps with the release of new firmware something will change for the better, but for now that’s it.
| Battery capacity | Reading mode | Video mode | 3D Game Mode | |
| Lenovo Vibe X2 | 2300 mAh | 13:00 | 6:00 am | 3 hours 15 minutes |
| Meizu MX4 | 3100 mAh | 12:00 pm | 8 hours 40 minutes | 3 hours 45 minutes |
| TCL Idol X+ | 2500 mAh | 12:30 pm | 7:20 am | 3:00 am |
| Sony Xperia Z3 | 3100 mAh | 20:00 | 10:00 am | 4 hours 50 minutes |
| HTC One M8 | 2600 mAh | 22:10 | 13:20 | 3 hours 20 minutes |
| Samsung Galaxy S5 | 2800 mAh | 17:20 | 12:30 pm | 4 hours 30 minutes |
| TCL Idol X+ | 2500 mAh | 12:30 pm | 7:20 am | 3:00 am |
| Lenovo Vibe Z | 3050 mAh | 11:45 am | 8:00 am | 3 hours 30 minutes |
Continuous reading in the FBReader program (with a standard, light theme) at a minimum comfortable brightness level (brightness was set to 100 cd/m²) lasted almost 13 hours until the battery was completely discharged, and when continuously watching videos in high quality (720p) with the same brightness level through the home Wi-Fi network, the device lasted 6 hours. In 3D gaming mode, the smartphone worked for more than 3 hours.
The smartphone charges quite quickly - fully charging the battery lasts about 2 hours.
Bottom line
To summarize the review of Lenovo Vibe X2 is very simple: a new smartphone with basic characteristics that are not inferior to the flagship, organized on the latest top-end platform and offered at the same time at the price of a product for the mass market, which it, in fact, is, is more than worthy of the closest attention of users. Yes, the device does not have some functions and properties, without which it cannot be called a true flagship, but it was not intended to be one. Lenovo Vibe X2 is aimed at mass demand and is offered at an interesting price, while it can offer the most powerful system, attractive design, high-quality build, decent screen and camera, LTE support and even expanded equipment. You can probably find fault with some little things like the lack of NFC and USB OTG, but for most users this is not yet a critical drawback. At the same time, all the main parameters of the new product are at a decent level, the smartphone turned out to be very interesting, and given the fact that Lenovo has now “frozen” prices in rubles at least until the end of the year, it turns out that we now have one of the most favorable prices in Europe. Keeping in mind the attractive design of this well-coordinated mobile device and the simply luxurious packaging in which it is delivered to stores, the Lenovo Vibe X2 could be an interesting choice as a gift for the New Year holidays.

The appearance is unusual and very pleasant for me. Light, very light. Although it costs Android 4.4, the interface developed by the manufacturer suits me quite well, everything is at hand, everything can be changed. LTE is basically what started the whole fuss because of it. And also Buns!!! Buns in the form of a film and a cover (bumper) included. Well, the price, so to speak, is still the old one.

The camera seems to be 13, but it would be nice to upgrade it in software. I don’t really like the automatic detection of the region of calling subscribers, it detects it incorrectly, but you can’t turn it off. Although not critical, it is still an inconvenience. There is also a problem with numbers in calls, it is not clear on what principle sometimes removes +7 from the number in calls, and when you make a new call they say that the number was dialed incorrectly, you have to look for the contact in the book again and call from there.

Camera - this can be solved by installing third-party programs that provide real image quality.
The battery - well, there’s nothing you can do about it, you have to pay for the thinness of the phone, but for me the operating time was much improved by using a utility that disables the 3G data transfer function in the background and removing the factory security after obtaining root rights. The effect in energy consumption is really high and the phone now really lasts for a day.

1. Camera (I gave it 4* because of it): maybe my hands are crooked, but the photos always turn out blurry (I’ve never gotten a clear photo). The quality of the photo in the dark is even worse (if there is something white in the photo, it completely takes over the flash). Before this I had an HTC with 8 megapixels, the photos were much better quality (even at night with flash), although they were also not ideal.
2. The phone has some kind of built-in feature that determines by phone number and shows on the screen the region to which you are calling or from which they are calling you. So, for example, the phone identifies the Kaluga region as the Chelyabinsk region. It correctly identifies only Moscow and the Moscow region, as well as if the call is to a landline phone (everything is clear here, based on the city code). But you can simply ignore this.
3. A couple of times
The manufacturer Lenovo has firmly established itself in the mobile device market. The range of gadgets is replenished with new models of different price segments. In this review we will talk about the Lenovo Vibe X2 (Vibe X update), and we will also talk about the differences between the Lenovo Vibe X2 and X2 Pro.
Design
The body consists of several layers, the boundaries of which are clearly visible, which is the calling card of this gadget. Each layer has a different color design. The buyer can choose between White, Black and Red versions of the smartphone. The phone is comfortable to hold in your hand. The front panel is covered with special protective glass.
On the front there is a front camera, a speaker and three touch buttons. At the back there is a main camera and flash. There is a headphone output at the top, and a microUSB output at the bottom.
On the right side there is a power button and a volume rocker. On the left side there is a slot for a microSIM card.
Display
The 5-inch IPS display of the smartphone has an HD resolution of 1920×1080. Even in bright light, working with the phone will be comfortable thanks to the anti-glare coating. The screen has a good reserve of brightness and reproduces colors well. Overall, the display is great for a variety of everyday tasks.
Cameras
Lenovo Vibe X2 has a 13 MP main camera and a 5 MP front camera. The image quality of the main camera is quite good. Video is recorded in HD format.
Hardware and software
The MediaTek MT6595M processor with 8 cores and 2 GB of RAM is responsible for the performance of the smartphone. You can run demanding games on your phone, which is a definite advantage. 32 GB of memory is allocated for data storage; this volume cannot be expanded due to the lack of a slot for microSD cards.
The phone runs on Android 4.4.2 with Vibe UI shell. The interface now has some cool widgets and options. Application icons can be organized using folders directly on the desktop.
Autonomy
Lenovo Vibe X2 is equipped with a 2300 mAh battery. This is relatively little considering the cost of the device. The review showed that the battery life of the smartphone is not very high. In maximum load mode, the gadget lasted only 2.5 hours. With moderate use, the phone will last about 6 hours without recharging. You can watch the video for just over 4 hours.
Comparison with Vibe X2 Pro
To briefly describe the X2 Pro model, we can say that it is a slightly enlarged Vibe X2 with two 13 MP cameras, a Qualcomm Snapdragon 615 processor and a 5.3-inch display. The main differences between the models are presented in the table.
Conclusions:
Lenovo Vibe X2 and Vibe X2 Pro are very interesting representatives of the middle class. They have an unusual design, a good display, and cool hardware. The only negative is low autonomy. If you choose between these two models, it is better to take the Pro, as you can expand the flash memory up to 128 GB using a microSD card.

SIM card
The SIM card is used in mobile devices to store data that certifies the authenticity of mobile service subscribers.
Mobile networks
A mobile network is a radio system that allows multiple mobile devices to communicate with each other.
| GSM GSM (Global System for Mobile Communications) is designed to replace the analogue mobile network (1G). For this reason, GSM is often called a 2G mobile network. It is improved by the addition of GPRS (General Packet Radio Services), and later EDGE (Enhanced Data rates for GSM Evolution) technologies. | GSM 850 MHz GSM 900 MHz GSM 1800 MHz GSM 1900 MHz |
| TD-SCDMA TD-SCDMA (Time Division Synchronous Code Division Multiple Access) is a 3G mobile network standard. It is also called UTRA/UMTS-TDD LCR. It was developed as an alternative to the W-CDMA standard in China by the Chinese Academy of Telecommunications Technology, Datang Telecom and Siemens. TD-SCDMA combines TDMA and CDMA. | TD-SCDMA 1880-1920 MHz TD-SCDMA 2010-2025 MHz |
| UMTS UMTS is an abbreviation for Universal Mobile Telecommunications System. It is based on the GSM standard and belongs to 3G mobile networks. Developed by 3GPP and its biggest advantage is providing greater speed and spectral efficiency thanks to W-CDMA technology. | UMTS 850 MHz UMTS 900 MHz UMTS 1700/2100 MHz UMTS 1900 MHz UMTS 2100 MHz |
| LTE LTE (Long Term Evolution) is defined as a fourth generation (4G) technology. It is developed by 3GPP based on GSM/EDGE and UMTS/HSPA to increase the capacity and speed of wireless mobile networks. The subsequent technology development is called LTE Advanced. | LTE 800 MHz LTE 1800 MHz LTE 2100 MHz LTE 2600 MHz LTE-TDD 1900 MHz (B39) LTE-TDD 2300 MHz (B40) LTE-TDD 2500 MHz (B41) |
Mobile communication technologies and data transfer speeds
Communication between devices on mobile networks is carried out using technologies that provide different data transfer rates.
Operating system
An operating system is a system software that manages and coordinates the operation of hardware components in a device.
SoC (System on Chip)
A system on a chip (SoC) includes all the most important hardware components of a mobile device on a single chip.
| SoC (System on Chip) A system on a chip (SoC) integrates various hardware components, such as a processor, graphics processor, memory, peripherals, interfaces, etc., as well as the software necessary for their operation. | MediaTek MT6595M |
| Technological process Information about the technological process by which the chip is manufactured. Nanometers measure half the distance between elements in the processor. | 28 nm (nanometers) |
| Processor (CPU) The primary function of a mobile device's processor (CPU) is to interpret and execute instructions contained in software applications. | 4x 2.0 GHz ARM Cortex-A17, 4x 1.5 GHz ARM Cortex-A7 |
| Processor size The size (in bits) of a processor is determined by the size (in bits) of the registers, address buses, and data buses. 64-bit processors have higher performance compared to 32-bit processors, which in turn are more powerful than 16-bit processors. | 32 bit |
| Instruction Set Architecture Instructions are commands with which the software sets/controls the operation of the processor. Information about the instruction set (ISA) that the processor can execute. | ARMv7 |
| Level 1 cache (L1) Cache memory is used by the processor to reduce access time to more frequently used data and instructions. L1 (level 1) cache is small in size and is much faster than both system memory and other cache levels. If the processor does not find the requested data in L1, it continues to look for it in the L2 cache. On some processors, this search is performed simultaneously in L1 and L2. | 32 kB + 32 kB (kilobytes) |
| Level 2 cache (L2) L2 (level 2) cache is slower than L1 cache, but in return it has a higher capacity, allowing it to cache more data. It, like L1, is much faster than system memory (RAM). If the processor does not find the requested data in L2, it continues to look for it in the L3 cache (if available) or in RAM memory. | 2048 kB (kilobytes) 2 MB (megabytes) |
| Number of processor cores The processor core executes software instructions. There are processors with one, two or more cores. Having more cores increases performance by allowing multiple instructions to be executed in parallel. | 8 |
| CPU clock speed The clock speed of a processor describes its speed in terms of cycles per second. It is measured in megahertz (MHz) or gigahertz (GHz). | 2000 MHz (megahertz) |
| Graphics Processing Unit (GPU) The Graphics Processing Unit (GPU) handles calculations for various 2D/3D graphics applications. In mobile devices, it is most often used by games, consumer interfaces, video applications, etc. | PowerVR 6200 |
| GPU clock speed Running speed is the clock speed of the GPU, measured in megahertz (MHz) or gigahertz (GHz). | 450 MHz (megahertz) |
