Whether eco characteristics 2. Information about the size and weight of the device, presented in different units of measurement. Used materials, offered colors, certificates
LeEco Le 2 received a large, even by today's standards, screen - its diagonal is 5.5 inches. Given the Full HD resolution, it boasts a decent pixel density (403 ppi) and a decent display-to-body ratio (74.4%). The entire front panel is protected by the "antiquated" Gorilla Glass 3, but it still has excellent scratch and shock resistance. The IPS-matrix has almost perfect viewing angles and realistic color reproduction.
The characteristics of the gadget, given its low cost, are far from being the worst. Under the hood there is a 10-core Helio X20 chipset, which is manufactured using a 20-nanometer process technology. It comes with 3 GB random access memory and 16/32/64 GB of built-in eMMC 5.1 memory. There is no room for a microSD card, so choose the model that has more ROM. As for the price of LeEko Le 2, on average in Russia it is sold for 12 thousand rubles.
The smartphone lacks the traditional 3.5 mm audio port, but it comes with a USB Type-C adapter. It runs on Android 6.0.1 Marshmallow operating system, which features EUI 5.8 user interface. She looks, undoubtedly, beautiful, but very unusual. There are many settings and functions, the shell is flexible and also extremely fast. The device has Wi-Fi 802.11ac, Bluetooth 4.1 and infrared port.
In addition, inside LeEko Le 2 there is a 3000 mAh battery, which will only be enough for one day of battery life. Fortunately, the user will be able to quickly charge it using Mediatek's Pump Express 3.0 technology. The charging process from 0 to 100% takes about an hour and a half, which is quite a good result.
Smartphones from the Chinese company LeEco, which previously bore the name LeTV, have already appeared in our reviews (LeTV 1s X500, LeTV One X600), but then this manufacturer was little known in Russia. Now, after the noisy release of the brand on Russian market, LeEco is worth telling in more detail. If in general outline then LeEco is a popular home electronics manufacturer and video content provider. His assortment includes not only TVs and smartphones, but even models of smart bicycles and smart cars. When it comes to video content, by 2010 the company had become the leading online video platform in China with a monthly audience of over 800 million users. She owns thousands of cinemas, the rights to hundreds of films and TV series, and even her own film studio, Le Vision Pictures (LeVP).
As a result, LeEco was able to create a unique vertically integrated ecosystem that combines an online platform, content, devices for viewing it (TVs and smartphones, virtual reality helmets) and mobile applications. Now she intends to conquer the Russian market as well: LeRee President Viktor Xu announced plans to invest from $ 0.5 billion to $ 1 billion in the Russian economy over three years. LeRee (LeEco Russia and Eastern Europe) is a subsidiary of the LeEco holding, specially created in 2016 to do business in Russia and Eastern Europe, as well as in the CIS countries.
It is clear that in this context smartphones are not the main product for LeEco, but just a platform for consuming paid content. A kind of your own "console", which is not a sin to implement at a cheaper price, but with great coverage, in the hope of profit from the monetization of their services. True, they are not yet optimized for Russia, so for the first time, domestic LeClub subscribers will receive partner content from Amediateka, Liters, ivi, Megogo and Zvooq. It is difficult to say whether such a subscription business model will be successful in Russia, time will tell. In our review, we traditionally turn to technical capabilities and consider in all details the most massive model of current smartphones presented in the LeEco range - Le 2.

Contents of delivery
The LeEco Le 2 smartphone is sold in a large rectangular box made of matte cardboard with a laconic design. On a black background, only the silvery company logo and a sticker with the main characteristics flaunt.
The set consists of a powerful mains adapter with variable output current (2/3 A; 3.6 / 8/12 V), connecting USB cable Type-C, ejecting needles, and a headphone adapter.
Appearance and usability
LeEco Le 2 received a large 5.5-inch screen and a metal body with an aluminum casing that covers everything except the front panel. Wide flat side edges and a slightly sloping rear wall have a matte rough surface. Two plastic inserts on the top and bottom of the back of the case, which cover the antennas of the communication modules, received a texture similar in color.
The LeEco Le 2 has a metal case, but everything here suggests that the manufacturer tried to minimize production costs as much as possible. Nobody bothered to give the metal surfaces any distinctive feature, such as a grinding effect. The same applies to the front part: the screen is covered with ordinary flat and transparent glass, there are no sloping edges like modern 2.5D glasses, there is no tint. Because of this, as well as the fact that the painted frame under the glass has no pattern, the front panel as a whole looks rustic.
The body is rather large and thick, but due to its low weight, strongly rounded corners in plan and good shape, the device does not feel massive in the hand. It fits comfortably in the pockets of clothes, fits comfortably in the palm of your hand, does not slip out, and there are no fingerprints on its matte surfaces. There are no complaints about the assembly: all parts are clearly fitted, no cracks or deflections were noticed.

The back panel, as usual, is given over to the main camera module, flash and fingerprint scanner. The camera module does not stick out beyond the surface of the case, so using a smartphone lying on the table is quite comfortable. The camera is equipped with an LED flash made of two multi-colored LEDs, the flash is quite bright. For some reason, the pad of the fingerprint sensor is made mirrored, and, of course, there are traces of any touch on it. This mirror, instantly covered with fingerprints, always looks sloppy and does not decorate the overall look, but only spoils it.
The slot for cards is located on the left side, you can install two Nano-SIM cards in it, but for a microSD memory card there is neither a separate place, nor the ability to install it instead of one of the SIM cards (that is, the slot is not hybrid). Hot swapping of cards is supported.
The front panel has an LED event indicator in the upper part above the screen, and a full set of necessary sensors installed right there, next to the earpiece grille, and a bright backlighting of the bottom row of touch buttons below the screen. Control buttons can be quickly locked and unlocked by simultaneously pressing the volume and power buttons. This is convenient: not everyone likes the touch buttons on the case, which are triggered at the slightest accidental touch, but here this issue is solved simply.
The side buttons on the right side are pretty stiff and take some getting used to. But in general, their location and size do not cause irritation, this is a complete order.
On the top end there is only a small dot of the infrared transmitter used to emulate the remote control. Without it, of course, there is nowhere in LeTV products, since all of them are positioned primarily as participants in the LeEco ecosystem, where the first place is now the consumption of video content by subscription. Soon, TVs of this brand will begin to be sold in Russia, and it will be even easier to interact with them using such a smartphone. However, even for an old Philips TV, our LeEco Le 2 could become a remote control without any problems.
The USB Type-C connector is installed in the middle of the bottom end; it supports connecting other devices and flash drives in USB OTG mode. On both sides of it, holes are symmetrically cut in the body, supposedly letting in sound from the speakers, but in reality, as usual, the speaker is hidden only behind one of these groups, the second is a props (perhaps there is a spoken microphone behind it).
The 3.5 mm audio jack was removed from the device altogether, standard headphones can only be connected to the USB Type-C connector using the supplied adapter. But headphones connected directly to the USB Type-C connector were not found in the kit, although the company has already presented such headphones with an active noise cancellation system and support for its own CDLA standard, certified by the Chinese Musicians Association. The USB port allows uncompressed audio to be streamed to a decoder inside these headphones, and these headphones do not require a separate power supply.
In Russia, the device can be purchased in a golden case, as well as in a dark gray version, but in other markets there are other color options.
Screen
LeEco Le 2 is equipped with an IPS touchscreen display with dimensions of 68 × 121 mm. Diagonal - 5.5 inches, resolution - 1920 × 1080 pixels, dot density is approximately 401 ppi. The screen here is not "frameless", the width of the frame on the sides is about 3 mm.
The brightness of the display can be adjusted manually or by automatic adjustment based on the operation of the ambient light sensor. The AnTuTu test diagnoses support for 10 simultaneous multitouch clicks. When you bring the smartphone to your ear, the screen is adequately locked and unlocked using the proximity sensor. There are no functions to turn on and off the screen by tapping on the glass, but you can wake up the smartphone by touching the fingerprint scanner.

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 test sample.
The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are no worse than those of the Google Nexus 7 (2013) (below, just Nexus 7). For clarity, here is a photo in which a white surface is reflected in the turned off screens (on the left - Nexus 7, on the right - LeEco Le 2, then they can be distinguished by their size):
The screen of the LeEco Le 2 is slightly darker (brightness in the photos is 105 versus 112 in the Nexus 7). The doubling of reflected objects in the LeEco Le 2 screen is very weak, which 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 type screen - One Glass Solution). Due to the smaller number of boundaries (such as glass / air) with very different refractive indices, such screens look better in conditions of intense ambient light, but their repair in the case of cracked outer glass is much more expensive, since the entire screen has to be changed. On the outer surface of the screen, there is a special oleophobic (grease-repellent) coating, which is noticeably better in efficiency than that of the Nexus 7. Therefore, fingerprints are removed much easier, and appear at a slower rate than in the case of ordinary glass.
With manual brightness control and with output white field full screen the maximum brightness value was about 440 cd / m², the minimum - 4 cd / m². The maximum brightness is quite high, and given the excellent anti-glare properties, readability even on a sunny day outdoors should be at an acceptable level. In complete darkness, the brightness can be lowered to a comfortable value. In the presence of automatic brightness control by the light sensor (it is located to the left of the front speaker slot). In automatic mode, when the ambient light conditions change, the screen brightness both increases and decreases. The operation of this function depends on the position of the brightness adjustment. If it is 100%, then in complete darkness the auto-brightness function reduces the brightness to 40 cd / m2 (normal), in an office illuminated with artificial light (about 550 lx) it sets to 340 cd / m2 (bright), in a very bright environment (corresponds to outdoor lighting on a clear day, but without direct sunlight- 20,000 lux or slightly more) the brightness is increased to 440 cd / m² (to the maximum, which is needed); if the slider is about 50%, then the values are as follows: 7, 260 and 440 cd / m² (the first value is low, the second is high), the control for 0% is 4, 150 and 440 cd / m² (only the first value is low). It turns out that the automatic brightness control function works more or less adequately, and to some extent allows the user to customize his work for individual requirements, although we did not get a completely satisfactory option. At any brightness level, there is no significant backlight modulation, so there is no screen flickering either.
This smartphone uses an IPS-type matrix. The micrographs show the typical IPS subpixel structure:
For comparison, you can see the gallery of photomicrographs of screens used in mobile technology.
The screen has good viewing angles without a significant color shift even with large gaze deviations from the perpendicular to the screen and without inverting (except for the darkest when deviating along one diagonal) shades. For comparison, here are photographs in which the same images are displayed on the screens of LeEco Le 2 and Nexus 7, while the brightness of the screens was initially set to about 200 cd / m2, and the color balance on the camera was forcibly switched to 6500 K.
White field perpendicular to screens:
Note the good uniformity of brightness and color tone of the white field.
And the test picture:
Colors on the screen of LeEco Le 2 have close to natural saturation, but the color balance is noticeably shifted towards the blue, "cold" area.
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 did not change much on both screens, but in the LeEco Le 2 the contrast decreased to a greater extent due to the strong black highlighting.
And a white box:
The brightness at an angle at the screens decreased (at least 5 times, based on the difference in exposure), but in the case of LeEco Le 2, the drop in brightness is greater. When deviated diagonally, the black field is lightened strongly and acquires a slight reddish tint. The photos below demonstrate this (the brightness of the white areas in perpendicular to the plane the direction of the screens is the same!):
And from a different angle:
With a perpendicular view, the uniformity of the black field is average:
The contrast (approximately in the center of the screen) is high - about 1100: 1. The response time for the transition black-white-black is 26 ms (14 ms on + 12 ms off). The transition between gray tones of 25% and 75% (based on the numerical value of the color) and back takes 41 ms in total. The gamma curve, plotted using 32 points with equal intervals in terms of the numerical value of the shade of gray, did not reveal a blockage in either the highlights or the shadows. The exponent of the approximating power function is 2.41, which is higher than the standard value of 2.2. In this case, the real gamma curve significantly deviates from the power dependence:
This device has a dynamic adjustment of the backlight brightness in accordance with the nature of the displayed image - the brightness of the backlight decreases in dark images in the middle. As a result, the obtained dependence of the brightness on the hue (gamma curve) does not correspond to the gamma curve of a static image, since the measurements were carried out with sequential display of gray shades on almost the entire screen. For this reason, a number of tests - determining the contrast and response time, comparing the black illumination at angles - we carried out (however, as always) when displaying special templates with a constant average brightness, and not single-color fields across the entire screen. In general, such a non-switchable brightness correction does nothing but harm, since a constant change in the brightness of the screen can at least cause some discomfort, reduce the visibility of gradations in the shadows in the case of dark images and the readability of the screen in bright light, since the brightness is not the brightest in the average image illumination is underestimated, and its already not an excess.
The color gamut is slightly wider than sRGB:
The spectra show that the matrix filters moderately mix the components together:
However, the deviations of the coordinates of the primary colors from the vertices of the sRGB triangle are small, so visually the colors on this screen practically do not differ from the natural ones. In this device, in the screen settings, it is possible to choose one of four profiles.
All photos above are taken with the default profile selected - Letv... When choosing a profile Bright the coverage triangle is skewed:
And in the profile Estest. coverage is compressed to the sRGB borders:
In profile Soft the coverage does not change, but the color balance is corrected - excessive cyanosis is reduced, the image becomes more pleasant for the eyes:
Let's see how this affects the values of the color temperature and deviation from the spectrum of a black body (ΔE) in different shades of gray:
In the case of the default profile, the color temperature is significantly higher than the standard 6500 K and the ΔE varies greatly from hue to hue - this negatively affects the visual assessment of the color balance. In case of a profile Soft the color temperature is closer to 6500 K, but ΔE increases, although it still remains below 10 in most shades, which is considered an acceptable indicator for a consumer device. The second option is probably better.
To summarize: the screen has a fairly high maximum brightness and has excellent anti-reflective properties, so the device can be used outdoors without any problems even on a sunny summer day. In complete darkness, the brightness can be lowered to a comfortable level. It is also permissible to use a mode with automatic brightness adjustment, which works more or less adequately. The advantages of the screen include an effective oleophobic coating, no air gap in the layers of the screen and no flicker, as well as high contrast. The disadvantages are the low stability of black to deviation of the gaze from the perpendicular to the plane of the screen, as well as non-switchable dynamic adjustment of the backlight brightness. Nevertheless, given the importance of characteristics for this particular class of devices, the screen quality can be considered high.
Sound
The smartphone sounds with high quality, the sound both in the headphones and from the speaker pleases with the breadth of the frequency range, saturation, purity and brightness of the sound. The volume margin is not excessive, but at any volume level, the sound is devoid of noise impurities and distortions. Dolby Atmos technology, which is gaining popularity among smartphone manufacturers, is also responsible for the sound quality.
In the conversational dynamics, the voice of the familiar interlocutor remains recognizable, the interlocutors on the other side also do not notice any noticeable distortions. The dictaphone records sound with high quality, a noise reduction system is present, and in general it copes with its tasks adequately. There is no FM radio in the device. The vibrating alert is above average in terms of power, it is well felt.

Camera
The smartphone is equipped with two modules digital cameras with a resolution of 16 and 8 megapixels - "24 megapixels for two cameras", as LeEco writes about this on its website, which looks funny. The front module here has a sensor with a resolution of 8 megapixels and a pixel size of 1.4 microns, a wide-angle lens (76.5 °) with an aperture of f / 2.2. The focus is fixed, there is no own flash. The quality of shooting for the level of selfies is average, sharpness and detail are sometimes lame, as well as the white balance. Such a smartphone could have a better selfie camera.
The main camera received a 16-megapixel sensor and a lens with an f / 2.0 aperture, fast phase detection autofocus and dual bright LED flash. The only thing missing is the stabilization function.
The control menu here is its own, it is clear and easy to use, everything you need is always in front of your eyes. You can manually adjust and set exposure, ISO, white balance, brightness, contrast, you can choose additional shooting scenarios such as night, HDR or beautification mode. You cannot transfer control of camera settings to third-party applications using the Camera2 API, there is no possibility of recording in RAW either.

The camera can shoot videos at maximum 4K resolution, but does not support 60 fps. There is a possibility of slow-motion recording at a speed of 120 fps, but in a low resolution of 720p, which does not make much sense, but manufacturers persistently insert such a mode. Apart from the absence of the stabilization function, which makes shooting on the go jerky, as well as not very high-quality recorded sound, otherwise there are no complaints about shooting video at maximum resolution. The picture is clear, rich, detailed and juicy, there are no artifacts or slowdowns. The sound, unfortunately, is not perfect, there is a familiar echo effect, more like the sound of water in a tank.

The camera is not very good at shooting indoors. |
 |
Foliage begins to merge already in the middle plan. |
 |
Strong sharpening on wires and relatively good detailing in the background. |
 |
The numbers of the nearest cars are distinguishable. |
 |
The foregrounds work well. |
 |
The camera copes well with macro photography. |
The camera works well, but is unstable. From time to time, it unpleasantly lathers the frame almost over the entire field, and this is not connected with exposure. Perhaps the program is periodically "lost" when it comes to small, non-contrasting details. However, in most cases, the result is clearly above average, even if we do not make allowances for the low light of the test shots. Despite the fact that there are many quite typical problems that are worth working on, the camera makes a good impression, and it will cope with documentary shooting accurately, and sometimes even with artistic.
Telephone part and communications
The network capabilities of LeEco Le 2 meet modern requirements: 11 LTE bands are supported, including three used in Russia, as well as two Wi-Fi bands, Bluetooth version 4.1, and all three satellite navigation systems - GPS, Glonass and Beidou ... There is only NFC. The connection speed in 4G networks and work with cellular networks do not cause any complaints: the smartphone instantly reconnects after a break, does not lose connection in areas of uncertain reception, and delivers high speeds in 4G. VoLTE calls over 4G network are supported.
There are no complaints about the operation of the navigation module, the first satellites during a cold start are detected within the first tens of seconds. The smartphone is equipped with a magnetic field sensor, on the basis of which the digital compass of navigation programs usually functions.
The smartphone supports dual SIM. The standard interface allows you to select a specific card for each of the functions in advance or right during the connection. Working with two SIM cards is organized according to the usual Dual SIM Dual Standby standard, when both cards can be in active standby mode, but cannot work at the same time - there is only one radio module here.

OS and software
The device uses 64-bit software platform Google Android version 6.0.1 with its own EUI 5.8 shell with the ability to update over the air.
The original Google interface has been completely redesigned, everything that can be changed here. The menu for installed applications has been removed, the notification menu has been improved, the reboot menu has been modified, the quick access menu has been significantly expanded (it opens here by pressing the extreme left button and is combined with the menu of the last open programs). It is possible to change the themes, completely disable the touch buttons under the screen, sort and distribute the application icons on the home screens at will.

In addition to the usual enlargement of fonts, you can choose the entire enlarged interface scale, as in the iPhone Plus series. The fingerprint sensor can be used not only to authorize the user when unlocking the screen, but also to control the camera, players, and also to unlock individual applications and photo galleries.
 |
 |
As for third-party applications, there are literally a few of them preinstalled here, all of them are useful. The main ones are the Phone Manager system utility, which optimizes work with memory, allows you to cleanly uninstall applications, monitors power consumption, etc., as well as a file manager. In addition, there is a weather widget and the aforementioned TV control application and other household appliances... Some functions may require authorization and Account in the LeEco system, which, by the way, supports its own cloud storage.

Performance
The hardware platform of the smartphone is based on the 8-core SoC Qualcomm Snapdragon 652, produced using 28-nanometer technology. It includes four powerful 64-bit ARM Cortex-A72 cores up to 1.8 GHz, complemented by four simpler 64-bit Cortex-A53 cores up to 1.4 GHz. For graphics processing in the SoC, the Adreno 510 video accelerator with an operating frequency of up to 600 MHz is responsible.
The amount of RAM of the smartphone is 3 GB, the amount of built-in flash memory is 32 GB (the user of which has about 23 GB of free space). The allocated memory capacity in LeEco Le 2 cannot be increased due to microSD cards, there is simply no slot for them here. But it is possible to connect external flash drives to the USB port in OTG mode.

We are already familiar with the Qualcomm Snapdragon 652 platform, we had to meet it, say, in the LG G5 se, and the test results of the review hero are similar. This SoC has established itself as a fairly powerful advanced platform - not top-end, but noticeably above average. Compared to competitors, it is not only twice as fast as the mid-level MediaTek Helio P10, but also in no way inferior to the flagship MediaTek X20.
In complex tests, the results turned out to be very impressive, about the level of the top solutions of last season, such as Qualcomm Snapdragon 808 or Mediatek MT6795T. At the same time, Snapdragon 652, in general, is not positioned as a flagship. Qualcomm Snapdragon 652 has confidently taken its place in the middle-upper segment, its capabilities are currently more than enough for any purpose, including demanding games. Unassuming "Tanks" run at maximum fps, heavy games with high graphics settings also do not slow down, do not crash or throttled the processor. The performance margin of this SoC should be enough for several future updates, in this regard, there are no complaints about LeEco Le 2.
Testing in latest versions complex tests AnTuTu and GeekBench:
All the results obtained by us when testing the smartphone in the most recent versions of popular benchmarks, we have summarized in tables for convenience. Several other devices from various segments are usually added to the table, 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, therefore, 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 gaming tests 3DMark, GFXBenchmark, and Bonsai Benchmark:
When testing in 3DMark for the highest performing smartphones, it is now possible 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 evaluating the speed of the javascript engine, you should always make allowances for the fact that the results in them significantly depend on the browser in which they are launched, so that the comparison can be truly correct only on the same OS and browsers, and this possibility is available when testing not always. In the case of Android OS, we always try to use Google Chrome.

To test the "omnivorous" video playback (including support for various codecs, containers and special features, such as subtitles), we used the most common formats that make up the bulk of the content available on the Web. Note that it is important for mobile devices to have support for hardware video decoding at the chip level, since it is often impossible to process modern versions using processor cores alone. Also, do not expect a mobile device to decode everything, since the leadership in flexibility belongs to the PC, and no one is going to challenge it. All results are tabulated.
According to the test results, the subject, to his delight, was equipped with all the necessary decoders that are needed to fully play most of the most common multimedia files on the network, including audio files. To play them successfully, you do not have to resort to using a third-party player - for example, MX Player. Although the AC3 audio format is played without problems in it, this is a rather rare case for a modern smartphone.
Further video playback testing was done by Alexey Kudryavtsev.
Theoretically, we could not check the possible support for adapters for outputting images to an external device due to the lack of an adapter option that connects to the USB Type-C port, 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)
Note: If both columns Uniformity and Skips green ratings are set, this means that, most likely, when watching movies, artifacts caused by uneven alternation and skipping of frames will either not be visible at all, or their number and visibility will not affect the viewing comfort. Red marks indicate possible problems with the playback of the respective files.
According to the criterion for outputting frames, the quality of video files playback on the screen of the smartphone itself is very good, since frames (or groups of frames) can (but are not required) to be displayed with uniform intervals of intervals and without frame drops. When playing video files with a resolution of 1920 by 1080 pixels (1080p) on a smartphone screen, the image of the video file itself is displayed exactly along the edge of the screen, one to one pixel by pixel, that is, in the original resolution. The brightness range displayed on the screen corresponds to the standard range of 16-235: all shades are displayed in shadows and highlights.
Battery life
The non-removable rechargeable battery installed in LeEco Le 2 has a capacity of 3000 mAh. According to the test results, the smartphone showed a confident average level in terms of battery life. In real scenarios of use, the device calmly lives an eventful day without recharging, and with economical operation it can last even more.
Testing has traditionally been carried out at the usual power consumption level, but the smartphone also has a standard power saving mode.
Continuous reading in the Moon + Reader program (with a standard, light theme) at a minimum comfortable brightness level (the brightness was set to 100 cd / m2) with auto scrolling lasted more than 13 hours until the battery was fully discharged, and with continuous high quality video viewing (720p) with the same brightness level through a home Wi-Fi network, the device can withstand 10 hours. In 3D games mode, the smartphone worked for about 5 hours.
The smartphone is charged quite quickly from the standard network adapter, the proprietary Qualcomm QuickCharge charging, here called Le SuperCharge, is supported. As a result, the device is fully charged from a standard mains adapter for 2 hours with a current of 0.6 A at a voltage of 9 V.
Outcome
As for the price of LeEco Le 2, everything is not easy here. The recommended price for the device is 15 thousand rubles, and a two-year warranty (1 + 1 year for club members), free screen repair within three months and courier delivery are supposedly promised. However, in fact, LeMall is still offering mandatory account registration with the expectation of a pre-order, or transferring it to AliExpress. If you manage to get a gift coupon, then such a smartphone will cost the lucky ones 10 thousand. In the future, they promise to open a branded offline store LeEco in the Atrium shopping center in Moscow.
In the end, the smartphone left a pleasant impression, but this is far from the level of top manufacturers like Apple and Samsung, with which the company representatives so self-confidently compared themselves during the Russian presentation. Le 2 is the level of solutions from Xiaomi, Meizu and Lenovo, and these companies certainly have something to offer for 15 thousand. In general, LeEco Le 2 has an average hardware platform in terms of performance, a good screen, sound system and a set of communication modules, quite satisfactory autonomy. The smartphone is very good in terms of its capabilities, no frank marriage, imperfections and shortcomings have been identified. For 10 thousand, this is already quite an interesting option to purchase, but at this price you still have to try to get it.
In conclusion, we suggest watching our video review of the LeEco Le 2 (X527) smartphone:

LeEco Le 2 looks pretty: shiny bevels and symmetrical elements look stylish and serious. There is not enough rounded glass - without it, the sharp edges cut unpleasantly into the palm.
There is an infrared port for controlling household appliances. You can install two nanoSIMs in the tray, but there is no place for a memory card in it. Under the screen are three touch-sensitive keys with backlighting, which turns off in sleep mode.
I carried my smartphone in jeans, a bag, threw it into my backpack, put it on the sand and hit the corners a couple of times. Not on purpose. For three weeks, not a single, even tiny, scratch appeared on the case. This is impressive.
A small mirror under the camera is a fingerprint scanner. It's good that it is here, but the sensor is very slow to understand: it takes almost a second to unlock. Compared to OnePlus and Huawei smartphones, the delay is noticeable.
Affordable yet powerful
The strongest feature of the LeEco Le 2 is its high performance. For three weeks of testing, the smartphone never rebooted, applications did not crash. Sometimes the case heated up for no reason, but only slightly, and then cooled down quickly.
Le 2 without brakes pulled such games as Modern Combat 5, Asphalt 8, Injustice, Unkilled and Angry Birds 2. The device was made to think only by the Navitel navigator, but not every flagship can cope with it.
A version of Le 2 with a Snapdragon 652 processor and 3 GB of RAM is being sold in Russia. There is also a Chinese version with a MediaTek Helio X20 processor. There is no point in ordering it: it is cheaper by only a couple of thousand, but without a guarantee, and Qualcomm's optimization is better.
There were no problems with the connection quality. The 4G network was confidently caught both in Moscow and during a trip to Europe. But the GPS is behaving strangely. On the map, the pointer spins wildly, reminiscent of a submarine locator.
Headphone jack is missing
Like the iPhone 7/7 Plus, the LeEco Le 2 also lacks a headphone jack. The trend of fashion is understandable, but why do this with a smartphone for 15,000 rubles? It is logical that a person limited by such a budget will not pay 3-4 thousand for wireless headphones.
Most importantly, it's very inconvenient without a headphone jack. On the plane, I could not charge my smartphone and listen to music at the same time, and in the car, I could not connect to the audio system via the AUX cable. The film from the flash drive via OTG was also not possible to watch.
Why is all this needed? To implement CDLA technology in a smartphone. It is LeEco's proprietary standard for high quality 24-bit / 192 kHz music transmission. Just like in expensive Hi-Fi players.
To appreciate the full power of CDLA, you need dedicated USB-C headphones. But in the bundle with Le 2 we get ... right, an adapter for an "outdated" audio jack. The sound through it is good (deep, with good detail and bass), but competitors can be just as good. An additional trump card is support for Dolby Atmos technology, which increases stage volume and adds a little low and high frequencies.

Adapter from USB Type-C to headphone jack in LeEco Le 2Bright display and pleasant interface
LeEco Le 2 has a 5.5-inch IPS-matrix with a resolution of 1920 x 1080 pixels. This is the gold standard for budget smartphones. The color reproduction is excellent, the brightness reserve is large, the light sensor works correctly, but with a delay of 2-3 seconds.
The screen does not fade under the sun and pleases with a good oleophobic coating. Only the black frame around it is wide - it looks out of place. By the way, the color rendition can be customized: there are four modes to choose from. My favorite is Letv, notable for its natural tones and correct white balance.
Every Chinese manufacturer strives to redraw Android in its own way. LeEco is no exception. The symbiosis of Android 6.0 and the proprietary EUI shell turned out to be successful. There is a neat and not overloaded interface, a lot of settings and excellent optimization - the system "flies".
