SIM card

A SIM card is used in mobile devices to store data confirming the authenticity of mobile service subscribers.

Mobile networks

A mobile network is a radio system that allows multiple mobile devices to exchange data with each other.

GSM GSM (Global System for Mobile Communications) is designed to replace the analog 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
UMTS UMTS stands for Universal Mobile Telecommunications System. It is based on the GSM standard and applies to 3G mobile networks. Developed by 3GPP and its biggest advantage is the provision of greater speed and spectral efficiency thanks to W-CDMA technology.	UMTS 850 MHz UMTS 900 MHz UMTS 1900 MHz UMTS 2100 MHz
LTE LTE (Long Term Evolution) is defined as fourth-generation (4G) technology. It was developed by 3GPP based on GSM / EDGE and UMTS / HSPA in order to increase the capacity and speed of wireless mobile networks. The subsequent development of technology is called LTE Advanced.	LTE 800 MHz LTE 900 MHz LTE 1700/2100 MHz LTE 1800 MHz LTE 1900 MHz LTE 2100 MHz LTE 2600 MHz LTE 700 MHz (B12) LTE 700 MHz (B28)

Mobile Technologies and Data Rate

Level 1 Cache (L1) The cache is used by the processor to reduce access time to more frequently used data and instructions. L1 (level 1) cache memory is small and works much faster than both system memory and other cache levels. If the processor does not find the requested data in L1, it continues to search for them in the L2 cache. With some processors, this search is performed simultaneously in L1 and L2.	32 kB + 32 kB (kilobytes)
L2 Cache L2 (level 2) cache is slower than L1, but instead it has a large capacity, allowing caching of more data. She, like L1, is much faster than system memory (RAM). If the processor does not find the requested data in L2, it continues to search for them in the L3 cache (if any) or in RAM memory.	512 kB (kilobytes) 0.5 MB (megabytes)
The number of processor cores The processor core executes program instructions. There are processors with one, two or more cores. Having more cores improves performance by allowing multiple instructions to execute in parallel.	8

Inexpensive model in a metal case with a fingerprint scanner

This spring, at the International Mobile Congress (MWC 2016) in Barcelona, \u200b\u200bChinese company ZTE introduced its two new smartphones, Blade V7 and Blade V7 Lite. From the names it is logical to conclude that the models are related to each other, and the prefix “Lite” in the second means “lite”, or, simply, a simplified version of the first. We will meet with the older model a little later, but for now let's turn our eyes to the younger model Blade V7 Lite. Everything is simple with her: she quickly enters the Russian market, and under her own name. It is worth recalling that its immediate predecessor Blade V6, whom we met under the name Blade X7, had several names at once, and in different parts of the world was known under various names. It should also be noted that our market was the first where the Blade V7 Lite was launched. The smartphone is inexpensive, and in some ways even more interesting than the older model - this, at least, concerns the fingerprint scanner and front camera with a higher resolution. All other details can be found in our review of the ZTE Blade V7 Lite.

Contents of delivery

ZTE Blade V7 Lite comes in a small rectangular box made of hard matte cardboard. The box is designed simply, but neatly, the equipment does not match its volume, there is more free space inside than you need.

The kit consists of a network adapter (maximum output current 1 A), a USB connection cable, a stereo wired headset with rubber ear pads of an in-channel type, as well as a protective film on the screen, a paper clip and a thin booklet with documentation.

Appearance and usability

ZTE Blade V7 Lite quite logically repeats the design of its immediate predecessor Blade V6 (X7) and is less similar to the older V7 model of its subfamily, although there are, of course, intersections with it. The outer part of the case is based on a large metal cover made of aluminum (lightweight aircraft, as manufacturers like to call it). The cover is not integral: the inserts made of plastic, painted the color of metal, fall on part of the sides and ends, it is in them that all the connectors are installed.

The case of the ZTE Blade V7 Lite does not look more expensive than it actually is, it is quite simple, but the assembly and workmanship do not cause any particular complaints. A medium-sized five-inch device due to matte metal surfaces and a very small mass (only about 136 grams!) Is comfortably held in the hand, does not slip out. It is convenient for carrying in any pockets of clothes, angles strongly rounded in plan do not allow the ZTE Blade V7 Lite case to abut against the body.

The practical and, apparently, reliable ZTE Blade V7 Lite case is really excellent in hands, and its low weight is almost a record for a five-inch device. There are no glossy smooth surfaces on metal and plastic parts, these parts are completely not soiled. But the front glass, it seems, was deprived of a grease-repellent coating, since the screen is covered with fingerprints extremely quickly, and they do not scrub well.

Ergonomics are also a little lame: the side buttons here, unlike most modern devices, are distributed on both sides. There is no convenience in this, because when you click on one of the buttons, the other fingers rest on the opposite key and often press it too. I have to dodge and get used to holding the device with a slightly different grip, but why is all this necessary? The keys themselves are quite pleasant to the touch, large, protruding, not too hard.

The card slot is located on the right side, using the familiar hybrid slot for two SIM cards or one SIM card plus a microSD memory card. Both slots support Nano-SIM, the farm itself is made of metal, it is installed and removed without problems and distortions. Hot swapping is supported.

The front panel is completely covered with 2.5D glass with sloping edges, the rear wall also has rounded edges, but still there is a feeling that the previous Blade V6 (X7) was more sloping and rounded to the touch, here the edges are a little more rough and the glass rounded less than usual.

There is no LED indicator above the screen, there are standard sensors, a front camera and a speaker. A selfie camera, by the way, in the ZTE Blade V7 Lite has its own LED flash, which is quite unusual for a device of such a low level.

Nevertheless, there is an event indicator here, it is implemented as a ring pulsating with light on the central touch button below the screen. The other two buttons on either side of it are simply indicated by dots, so in the settings their purpose can be interchanged, and this will not cause visual discomfort.

On the back there is a main camera module with a single, but rather bright LED flash, as well as a fingerprint scanner. The camera module protrudes beyond the surface, so it is inconvenient to work with the device lying on a solid surface: it sways when touched. However, this does not really matter, because you still can’t get to the fingerprint scanner on a lying device, and without it the smartphone cannot be unlocked. The scanner is responsible for authorizing the owner of the fingerprint not only when unlocking the smartphone, but also when launching applications. It does not always work clearly, but erroneous recognition is still rare. By touching the scanner, the smartphone does not unlock, first you need to turn on the screen, and then touch the scanner area.

The main speaker is displayed on the back side, but this does not muffle the sound when the phone is on the table, since the speaker cover grill falls on a small bevel of the case. There are two grilles, but the sound comes out only through one of them, there are no stereo speakers here.

At the bottom end, the universal Micro-USB connector is habitually located in the center, supporting the connection of third-party devices in USB OTG (USB Host) mode. Nearby you can see the hole of the conversational microphone.

The hole of the second, auxiliary microphone could not be found - perhaps it is not in this smartphone at all. At the top there was only a single jack with a diameter of 3.5 mm for connecting headphones.

There is no mount for the strap on the case, the plugs are not covered with plugs, the device did not receive protection from moisture and dust. As for colors, the device is so far presented in the Russian market only in one thing - light gray.

Screen

ZTE Blade V7 Lite is equipped with an IPS touch screen combined with 2.5D glass with sloping edges. The physical dimensions of the screen are 62 × 110 mm, the diagonal is 5 inches, the resolution is 1280 × 720 pixels, the pixel density is 294 ppi. The sides around the screen have a width of 4 mm, and on top and bottom the indents are 16 mm, the frame is quite wide. The manufacturer painted the frame around the display black, so that when the display is off, it looks like a "frameless", but in reality the device is far from that.

The brightness of the display can be adjusted manually, there is also an automatic adjustment, among the sensors there is an ambient light sensor. Multi-touch technology supports up to 5 simultaneous taps. When you bring the smartphone to your ear, the screen is blocked by the proximity sensor. Double tapping on the glass awakens the screen, it is also possible to activate by drawing special characters.

A detailed examination using measuring instruments was carried out by the editor of the “Monitors” and “Projectors and TV” sections Alexey Kudryavtsev. We give 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 that is resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are better than those of the Google Nexus 7 (2013) screen (hereinafter simply Nexus 7). For clarity, we present a photo on which a white surface is reflected in the turned off screens (on the left - Nexus 7, on the right - ZTE Blade V7 Lite, then they can be distinguished by size):

The screen of the ZTE Blade V7 Lite is slightly darker (brightness in photographs 106 compared to 114 for Nexus 7). The doubling of reflected objects in the ZTE Blade V7 Lite 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 - One Glass Solution type screen). Due to the smaller number of boundaries (such as glass / air) with very different refractive indices, such screens look better under conditions of strong external illumination, but repairing them in the case of a cracked external 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 (it is noticeably worse in efficiency than Nexus 7), so fingerprints are removed a little easier and appear at a lower speed than in the case of ordinary glass.

With manual brightness control and when displaying a white field in full screen, the maximum brightness value was about 310 cd / m², the minimum - 10 cd / m². The maximum brightness is low, however, 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 light sensor (it is located to the right of the front camera eye). 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 slider. If it is 100%, then in complete darkness the auto brightness function reduces the brightness to 90 cd / m² (too much), in an office lit by artificial light (about 400 lux) it sets to 190 cd / m² (normal), in a very bright environment (corresponds to illumination on a clear day outdoors, but without direct sunlight - 20,000 lux or slightly more) the brightness rises to 310 cd / m² (to the maximum - this is necessary); if the adjustment is approximately 50%, then the values \u200b\u200bare as follows: 10, 105 and 310 cd / m² (ideal combination); the regulator is 0% - 10, 15 and 310 cd / m² (the average value is underestimated, which is logical). It turns out that the automatic brightness adjustment function works absolutely adequately and allows the user to customize their work to individual requirements to some extent. At any brightness level, there is no significant modulation of the backlight, so there is no screen flicker.

This smartphone uses an IPS type matrix. 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 deviations of the gaze from the perpendicular to the screen and without inverting colors. For comparison, we present photographs on which the same images are displayed on the ZTE Blade V7 Lite and Nexus 7 screens, while the brightness of the screens was initially set to about 200 cd / m², and the color balance on the camera was forcedly switched to 6500 K. A white field is perpendicular to the screens:

We note a good uniformity of brightness and color tone of the white field. And the test picture:

The color balance varies slightly, the color saturation is normal, the picture is slightly darkened. Now at an angle of about 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 the contrast decreased in ZTE Blade V7 Lite to a greater extent due to blackening and a strong decrease in image brightness. And the white field:

The brightness at an angle of the screens decreased (at least 5 times, based on the difference in shutter speed), but the ZTE Blade V7 Lite has a much darker screen. The black field with a diagonal deviation is highlighted to an average degree and acquires a red-violet hue. The photos below demonstrate this (the brightness of the white areas in the direction perpendicular to the plane of the screens is the same!):

And from a different angle:

With a perpendicular look, the black field uniformity is good (here the brightness of the backlight is maximized):

Contrast (approximately in the center of the screen) is high - about 1500: 1. The response time for the black-white-black transition is 26 ms (14 ms on + 12 ms off). The transition between gray tones of 25% and 75% (according to the numerical value of the color) and vice versa in total takes 43 ms. Constructed at 32 points with an equal interval in the numerical value of the shade of gray, the gamma curve did not reveal a blockage in either highlights or shadows. The exponent of the approximating power function is 2.25, which is slightly higher than the standard value of 2.2, while the real gamma curve deviates slightly from the power dependence:

Due to the presence of a dynamic adjustment of the brightness of the backlight in accordance with the nature of the output image (in dark images, the brightness tends to decrease), the resulting dependence of the brightness on the hue (gamma curve) does not correspond to the gamma curve of a static image, since measurements were carried out with gray shades almost full screen. For this reason, we conducted a series of tests - determining contrast and response time, comparing black flare at angles - when displaying special patterns with unchanged average brightness, rather than plain colors in the entire screen. Let us present the dependence of brightness (vertical axis) on time when switching from a black field to white in the halves of the screen alternately, while the average brightness does not change and the dynamic adjustment of the backlight brightness does not work (graph 50%/50% ) And the same dependence, but with alternately displaying fields in full screen (graph 100% ), while the average brightness is already changing and the dynamic adjustment of the brightness of the backlight works with might and main:

In general, such a non-switched brightness correction does nothing but harm, since it reduces the distinguishability of gradations in the shadows in the case of dark images. In addition, this dynamic adjustment when displaying any image other than a white field in full screen, significantly lowers the brightness (which is already not in excess), which affects readability in bright light. Note that the adjustment is slow, so at least there are no annoying sharp jumps in the brightness of the backlight.

The color gamut is slightly different from sRGB:

The spectra show that the matrix filters to a moderate degree mix the components together:

As a result, the colors have a more or less natural saturation. The balance of shades on the gray scale is average, since the color temperature is significantly higher than the standard 6500 K, however, the deviation from the spectrum of the black body (ΔE) is below 10, which is considered an acceptable indicator for a consumer device. In this case, the color temperature and ΔE vary little from shade to shade - this has a positive effect on the visual assessment of the color balance. (The darkest areas of the gray scale can be ignored, since there the color balance does not matter much, and the error in measuring color characteristics at low brightness is large.)

This device has a fairly advanced system of profiles and settings, supposedly  providing the ability to adjust the color balance, etc. It is called Miravision. However, attempts to correct the color balance with it were unsuccessful, as the correction of color temperature leads to the fact that the shade of the midtones changes, and the white point is almost absent, it looks disgusting.

To summarize: the screen has a low maximum brightness, but it has excellent anti-glare properties, so the device can be used at least somehow outdoors, even on a summer sunny day. For conditions of complete darkness, you can set a comfortable brightness level. The mode with automatic brightness adjustment works adequately. The advantages of the screen include the lack of air gap in the layers of the screen and flicker, as well as close to sRGB color gamut. Significant disadvantages include a weak oleophobic coating, as well as non-disconnectable dynamic adjustment of the backlight brightness. Nevertheless, taking into account the importance of characteristics for this particular class of devices, the screen quality can be considered at least above average.

Sound

The ZTE Blade V7 Lite sounds just as uninteresting as the rest of the Blade series we've met before. And in the headphones, and in the main speaker, the sound is not only faded and colorless, with a predominance of only high frequencies, but also distortion and litter are noticeable. You cannot make out individual instruments; the higher the volume, the higher the noise background. However, it is worth noting this time a rather large supply of volume of the main speaker and its overall sonority, not to be called deaf.

To play tunes, the standard Google Play Music player is used, and to improve the sound, the same built-in sound system of the French company Arkamys, which was previously present in ZTE Blade smartphones, is used. There are no separate settings in it, there is only the ability to enable or disable this function as a whole. The standard player has a familiar equalizer with predefined values. In conversational dynamics, the interlocutor’s speech, timbre and intonation remain recognizable, but the sound is dull.

The FM radio with the ability to record programs from the air on the smartphone is available, it works only with the connected headphones. The built-in recorder is not particularly sensitive, there is no noise reduction, and apparently, an auxiliary microphone is not provided here at all.

There is a suspicion that the main 13-megapixel camera here, like in the Blade X7, is equipped with an 8-megapixel sensor, and the maximum resolution is achieved using image interpolation. The lens has an f / 2.0 aperture. Autofocus is quite fast, there is no electronic stabilization, video is recorded with a maximum resolution of only 720p. The maximum ISO value can be set manually to 1600, and in manual mode, you can affect the brightness, contrast, sharpness, set the white balance and select the metering point manually. It is not possible to transfer control of the camera settings to third-party applications using the Camera2 API; there is also no way to record images in RAW.

The camera can shoot video in maximum resolution up to 720p, there are no 4K modes and 60 frames / s. In general, the camera shoots video at an average level, the image is loose and full of artifacts, the sound is recorded well, although there is apparently no noise reduction system here.

The pictures have good sharpness according to the plans and the field, although to the edges it falls a little. The program works moderately, noise in the shadows can be found - both "cured" and unprocessed. Otherwise, the results are quite outstanding, slightly above average, so the camera can be recommended for documentary shooting, no more.

Telephone part and communications

The smartphone supports most of the ranges of 2G GSM, 3G WCDMA, and LTE Cat.4 wireless networks used in Russia. FDD LTE smartphone supports bands 3, 7 and 20 in all three bands most common among Russian operators. In practice, it was not possible to achieve high-speed LTE from the device with a SIM card of MTS operator in the same test places where other smartphones double high speed in the test program. A complete list of supported frequencies is as follows:

• GSM / GPRS / EDGE networks (850/900/1800/1900 MHz)
• WCDMA / HSPA + Networks (850/900/2100 MHz)
• LTE networks (1800/2100/2300/2600/800/850/900 MHz)

The remaining network capabilities of the smartphone are also modest: NFC is not present, as is Hot Knot; only one Wi-Fi band (2.4 GHz) is supported, there is Wi-Fi Direct, you can organize a wireless access point via Wi-Fi or Bluetooth 4.0. Micro-USB 2.0 connector supports connecting external devices in USB OTG mode.

The navigation module only works with GPS (with A-GPS), the domestic Glonass satellites the device does not see. The first satellites during a cold start are detected within a minute. The smartphone is equipped with a magnetic field sensor, on the basis of which a digital compass of navigation programs functions.

The smartphone supports two SIM cards in Dual SIM Dual Standby mode, when both cards can be in active standby mode, but cannot work at the same time - there is only one radio module. With 3G / 4G networks, a SIM card can work in any slot, but at the same time only one of the cards can function in this mode. To change the assignment of card slots, you do not need to swap places - this can be done directly from the phone menu. You can assign the desired card for calls or SMS in advance in the settings, or via the pop-up menu directly during the call, if it was not done in advance.

OS and software

The system uses a 32-bit Google Android software platform version 6.0 installed on a 64-bit SoC. There is no own shell here as such, only the appearance of the theme has been changed, the icons and navigation panel have been redrawn, and a separate menu for installed applications has been removed. Wide support for gestures has been added, including waved body, strokes on the screen and various characters.

There are not so many pre-installed third-party programs: there is a file manager, an alternative to UC Browser, there is a set of applications for working with office documents WPS Office and the ubiquitous Clean Master. Access to individual applications and even files can be limited by using fingerprint scanner authorization.

Performance

The hardware platform ZTE Blade V7 Lite is built on the basis of the quad-core 64-bit single-chip system (SoC) MediaTek MT6735P. The SoC configuration includes four Cortex-A53 processor cores operating here at a frequency of up to 1 GHz. For graphics processing, the Mali-T720 video accelerator is responsible. The amount of RAM is 2 GB, and about 10 GB is available for the user's needs in the device. There is the possibility of installing microSD cards up to 32 GB, but in practice, our Transcend Premium microSDXC UHS-1 128 GB test card was confidently recognized by the device. The device also supports connecting external devices to the USB port in OTG mode.

We have studied the capabilities of the MediaTek MT6735 level platform, this SoC belongs to the initial level, and here the maximum operating frequency of the CPU cores is reduced to 1 GHz. Accordingly, one should not expect any impressive results in tests from the device. In practice, the capabilities of MediaTek MT6735P are enough to work confidently in most standard applications, but it is not intended for demanding games. There were slowdowns in Modern Combat 5, the World of Tanks game runs more smoothly (at about 35-38 fps with subsidence up to 29 fps). You can play with a strong desire, but you still can’t get high graphics settings with such a screen and such a platform.

Testing in the latest versions of AnTuTu and GeekBench 3 comprehensive tests:

All the results we obtained when testing the smartphone in the latest versions of popular benchmarks, we have brought to the table for convenience. Usually several other devices from various segments are also added to the table, which were also tested on the latest versions of benchmarks (this is done only for a visual assessment of the obtained dry numbers). Unfortunately, in 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 at one time they passed the "obstacle course" on previous versions of test programs.

Graphics subsystem testing in 3DMark gaming tests,  GFX Benchmark, and Bonsai Benchmark:

When testing in 3DMark for the most productive smartphones, it is now possible to run the application in Unlimited mode, where the rendering resolution is fixed at 720p and VSync is disabled (due to which the speed can rise above 60 fps).

Bonsai benchmark	1896 (27 fps)	2532 (36 fps)	2003 (29 fps)	4119 (59 fps)	3515 (50 fps)

Cross-platform browser tests:

As for the benchmarks for evaluating the speed of the javascript engine, you should always make a discount on 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 is possible when testing not always. In the case of the Android OS, we always try to use Google Chrome.

Heat shots

Below is a thermal photograph of the back surface obtained after 10 minutes of running the battery test in the GFXBenchmark program (closer to white - higher temperature):

It can be seen that the heating is slightly more localized in the upper left part of the device, which, apparently, corresponds to the location of the SoC chip. According to the heat chamber, the maximum heating was only 34 degrees (at an ambient temperature of 24 degrees), this is very small.

Play video

To test the “omnivorous” when playing videos (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 hardware-based video decoding support at the chip level, since it is most often impossible to process modern versions using processor cores alone. Also, you should not expect decoding of everything from a mobile device, since the lead in flexibility belongs to the PC, and no one is going to challenge it. All results are tabulated.

According to the test results, the test subject was not equipped with all the necessary decoders that are needed to fully play most of the most common multimedia files in the network, in this case, sound files. To successfully play them, you will have to resort to the help of a third-party player - for example, MX Player. True, it is also necessary to change the settings and manually install additional custom codecs, because now this player does not officially support the AC3 audio format.

Format	Container, video, sound	MX video player	Native video player
BDRip 720p	MKV, H.264 1280 × 720, 24fps, AAC	plays normally	plays normally
BDRip 720p	MKV, H.264 1280 × 720, 24fps, AC3		video plays normally, no sound

BDRip 1080p	MKV, H.264 1920 × 1080, 24fps, AC3	video plays normally, no sound	video plays normally, no sound

Further testing of video playback performed Alexey Kudryavtsev.

We did not find the MHL interface, like the Mobility DisplayPort, in this smartphone, so I had to confine myself to testing the output of the image 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 “Testing Technique for Video Playback and Display Devices. Version 1 (for mobile devices) Red marks indicate possible problems associated with playing the corresponding files.

According to the criterion for outputting frames, the playback quality of video files on the screen of the smartphone itself is good, since frames (or groups of frames) can (but are not required to) be displayed with a more or less uniform rotation of intervals and almost without frame drops. With the exception of files with 60 fps, in which case many frames are skipped. The reason is atypically low refresh rate of the screen equal to about 49.5 Hz, so even files with 50 frames / s are reproduced either with a periodic skip of one frame, or a little slower. When playing video files with a resolution of 1280 by 720 pixels (720p) on the smartphone screen, the image of the actual video file 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 16–235 - all shades of gradation are displayed in the shadows and in the lights.

Battery life

The non-removable battery installed in the ZTE Blade V7 Lite has a capacity of 2500 mAh. In the absence of a productive platform or an energy-intensive high-resolution screen, the smartphone expectedly demonstrates quite good autonomy results. But you need to be aware that this is achieved due to low productivity and low graphics settings, the device is weak in multimedia tasks. The smartphone quietly survives until the evening charge, in general, it can last about a day and a half during normal operation. There is an energy-saving mode in the smartphone, but testing, as usual, was carried out without involving such functions.

Continuous reading in the Moon + Reader program (with a standard, light theme) with a minimum comfortable brightness level (brightness was set to 100 cd / m²) with auto-scrolling lasted until the battery was completely discharged a little less than 13.5 hours, and when watching video in high quality without interruption (720р) with the same brightness level through the home Wi-Fi network, the device almost reached the mark at 9 o’clock. In 3D games, the smartphone worked for more than 5.5 hours.

The smartphone’s battery is charged from a standard network adapter in about three hours with a current of 0.9 A at a voltage of 5 V.

Total

ZTE Blade V7 Lite, as already mentioned at the very beginning, first went on sale in the Russian market. Here he is estimated at 14 thousand rubles in official retail (but offers from 11 thousand can be found). In principle, against the background of price tags of modern top-end smartphones, such a cost the language will not turn out to be called high. However, this is not the case when you can say that the smartphone is extremely interesting to purchase at this price. No, the ZTE Blade V7 Lite is a rather modest device in terms of all technical parameters and capabilities with weak or at best average screens, cameras, sound, performance, communication capabilities. Even the smartphone’s level of autonomy did not shine, although generally “hardy” budget devices with low performance (precisely because of this low performance) are not uncommon.

What the ZTE Blade V7 Lite really doesn’t take away is the pleasant to the touch and practical housing, which is mostly made of metal. Also, from the advantages of the model, one can note the presence of a fingerprint scanner, which is extremely useful for people who care about the safety of personal data. But on this, in general, all the pluses end there. ZTE Blade V7 Lite is a real workhorse without a hint of multimedia focus. This is a low-performance, but reliable smart phone of a large industrial giant of the industry, officially presented here, and therefore supported by warranty conditions, which is also important.

The approach of spring stimulates the emergence of fresh technical ideas for which there is still no shortage of smartphones in the world. The end of February was marked by a premiere boom, causing considerable excitement, primarily among developers seeking to really assess their commercial prospects for 2016. Each manufacturer of gadgets voices its spring tune, which is quickly picked up by an army of thousands of fans. Introducing the public smartphone ZTE Blade V7, did this company ZTE. But what exactly does the newcomer from the Celestial Empire carry, and we will try to find out now.

Not alone, and therefore not weak

Sharing the traditions of other smart families ZTE Blade B7  He arrived at the exhibition not alone, but with the support of his younger brother ZTE Blade V7 Lite, which only gave confidence. Even before finding out what is covered by a solid metal case, the public was honored to see a phone model whose thickness in some places does not exceed 3.5 mm, but on average it is not thicker than 7.5 mm. And this is actually not typical. Someone even found something similar in appearance with the iPhone 6. It is assumed that the device will first of all receive recognition from young people or those who identify with it.

Face to face

The front decoration of the device running Android Marshmallow 6.0 was a 5.2-inch matrix with a resolution of 1920 × 1080p, which is under the reliable protection of 2.5D glass, ending in smooth bends of the profile. This is not new, but still fresh and relevant. In front there is only one control key in the form of a ring, a speaker and a microphone.

As a working basis, the manufacturer chose the MediaTek MT6753 chipset, which has 8 cores and operates at a frequency of 1.3 GHz. Optimistic is the presence of 2 GB of RAM, behind which there is a 16-gigabyte potential of the internal storage unit, plus a reserve in the form of a microSD slot, which, if desired, can take a second SIM-card. In a word, the cameras on the smartphone are good: the main one with a resolution of 13 megapixels and phase detection autofocus (PDAF), front - 5 megapixels. Note the advanced gesture control functionality of Smart Sence.

The 2500 mAh battery will allow you to stay in the company of the gadget without recharging for about a day and a half or a day in intensive use.

Market prospects

It is no secret that the device takes up positions closer to the middle of the functional vertical and with all its nature proves that this is its place, no matter where it is on the market. Most likely, the domestic user will see this product later than the V7 Lite, whose debut in Russia is scheduled for spring.

It used to be this way: when purchasing an Android smartphone of the middle price category, the buyer received a rather faceless device with a completely standard, unremarkable exterior, but plus or minus good technical characteristics. We are not talking about the fact that then all the middle-end gadgets were ugly or inconspicuous. No, they were just very similar. Now, many first-tier manufacturers have begun to make inexpensive gadgets with an interesting appearance, but rather boring features. Like it or not, you have to choose: either one or the other, but there are not very many compromise solutions combining an interesting design and a decent hardware in this price category. In theory, the ZTE Blade V7, which is sold for 15 thousand rubles, can become just that.

⇡ Appearance and ergonomics

The new ZTE smartphone is made of aluminum, which is still a rarity in the middle price segment. The case of the device is non-separable and relatively strong - when squeezing the sides, there are no characteristic colored “stains”, but when pressed from above we can see them. However, for this you need to try. Rigidity ribs in the construction are enough; we have no complaints about the assembly.

The dimensions of the case in the Blade V7 are pretty standard for an Android smartphone with a screen diagonal of 5.2 inches. The frames around the display are not very wide. Due to this, it is quite comfortable to work with the device with one hand. The thumb easily reaches anywhere on the screen; you don’t have to shift the device in the palm of your hand.

The power key of the device is embossed, it’s nice to press it. It is located on the right side. Next to it is a slot for two cards. You can install either two Nano-SIM, or one SIM card and one microSD in the device. As always in such cases, we complain that there is no separate slot for a memory card. The volume control keys are on the left side. The headset jack is on the top, the micro-USB interface is on the bottom. Next to the latter is a slot in the external speaker. The location is good - the speaker does not overlap with the palm of the palm when the device is on the table or when it is in the hands.

The back panel is rough, so the Blade V7 does not slip even in a wet palm. She does not collect prints - the device turned out to be practical. Plastic inserts in the upper and lower parts of the “back” fit perfectly - they do not creak and do not play. The device exists in three colors: gray, graphite and gold.

Additionally
