The ZTE Axon 7 mini is not a smaller copy of the 5.2-inch flagship, even if visually it is very similar. This smartphone simpler camera, SoC Qualcomm Snapdragon 617, but it is equipped with an AMOLED display, a pair of good speakers, an NFC module, and a dedicated AKM sound processor, but it costs significantly less than the Axon 7.
In general, at first glance, this is an excellent solution for users who do not need a “shovel” and high performance in gaming applications, but still require high-quality sound and display. Let's see how it works and whether it can meet such requirements.

Appearance
Externally, Axon 7 mini is extremely similar to the older model, so without looking closely it’s even difficult to understand which version it is. And only when you take it in your hand does everything fall into place, because a smaller body is much more convenient. From a subjective point of view, it is smartphones with a screen diagonal of 5.2 inches or so that are the most optimal solution, because in a medium-sized hand such a smartphone is still comfortable, and watching web pages, videos or even playing is already convenient, although not as good as in larger models.

The appearance of the device almost exactly repeats the design of the Axon 7, which was developed within the walls of BMW Designworks, but for some reason this is not indicated in the press releases of the tested model. But a reminder of this is the inscription on the cover of the smartphone “Designed in the USA”. There are only three distinctive features, not counting weight and size indicators - different surface treatment decorative grille speakers, the absence of dedicated touch keys, and the absence of a tiny plastic insert above the camera window. Otherwise, everything is identical - similar general outlines, similar materials and coating, as well as the placement of controls and other functional elements. The assembly of the device is generally of high quality, but when you lightly tap on the body, the volume control and lock keys rattle a little, which was not noticed with the older model.
On the front side, in addition to the screen, there are a pair of speakers, a front camera window, as well as an activity indicator and a proximity/light sensor unit. On the back side in the upper part there is a camera block that protrudes slightly above the general surface, which can cause damage to the protective glass. Also at the top of the panel there is a fingerprint sensor and a two-color LED flash.
On the left side surface, only a double SIM card tray is visible, instead of one of which a microSD memory card can be installed. On the right side surface there are keys for locking and volume control.
At the bottom end you can see the USB Type-C connector and the built-in microphone hole. There is also a microphone on top, as well as a mini-jack audio jack (3.5 mm).

Software
The smartphone uses Android 6 OS with the proprietary MiFavor 4.0 shell. We managed to consider this combination during testing of the ZTE Axon 7, so we will not focus on it. The only significant difference is the virtual keys on the screen, while the older model has physical touch keys. In the case of Axon 7 mini, their functions can also be reassigned. Unfortunately, as in the case of the flagship, an update to Android 7 is not yet expected, and there are not even unofficial firmwares based on Nougat, although they are available for the older model, for example, LineageOS 14.1.
Display
As with the older model, the tested smartphone uses an AMOLED display, but its diagonal and resolution are slightly smaller - 5.2 inches and 1920x1080 pixels. The display supports up to 10 simultaneous touches. There is an oleophobic coating, but it is not as effective as in the case of the Axon 7, although in theory it should have been identical. The disadvantages inherent in AMOLED displays are well known to everyone, but there is no purple tint on dark colors, no flickering, much less graininess, was noticed. The only drawback that really makes itself felt is the low brightness compared to IPS matrices, which in the case of the tested smartphone was 320.36 cd/m2, which is not always enough, especially when working with the phone under direct sunlight. sun rays. The low brightness of the display is directly related to the high power consumption when displaying light colors.
The advantages of AMOLED displays are also well known: huge viewing angles and contrast, low power consumption when displaying dark tones, and a larger color gamut. Actually, the color gamut turned out to be much wider than the standard color space sRGB, but color accuracy is not the highest. The DeltaE deviation on the gray scale increases with brightness from 1.8 to 18.2. On primary colors (CMYRGB), the DeltaE deviation is in the range of 6.0...12.6. For non-professional equipment, a Delta E deviation of up to 10 is considered normal. The color temperature in the standard display mode is slightly too high and, depending on the luminosity, ranges from 7611...8126 K.

Sound
The tested smartphone, like the Axon 7, is equipped with a pair of speakers, one of which simultaneously serves as a system speaker and a conversation speaker. However, installing a pair of speakers is not so a big problem even in a limited space, but finding a place for two high-quality speakers and organizing a good sound picture is much more difficult. But the developers succeeded and the sound turned out to be very pleasant, without obvious defects, with a clearly noticeable high-frequency range and punchy bass. Moreover, by smartphone standards the sound can be called deep. But what surprised me most was the maximum volume. When playing a sinusoidal signal with a frequency of 1 kHz at a distance of 1 meter from the smartphone, a level of 81.2 dBA was recorded, which is currently best result among all the smartphones we tested. The difference in the volume of the speakers of the ZTE flagship and the smartphone being tested is almost 6 dBA, which is almost a double difference in volume level. In general, the mini version was a pleasant surprise here.
For high-quality playback of audio files, a separate sound chip manufactured by Asahi Kasei Microdevices is used, which, as experience in testing the ZTE Axon 7 has shown, really provides high-quality playback and high level volume on the analog audio output. When playing a 1 kHz sine wave and running into a 32 ohm load, the audio output recorded a level of 279.6 mV, which is not anything remarkable. In general, this is a good indicator for a middle-class smartphone, but it will be difficult for a smartphone to drive headphones even with a medium impedance, not to mention high-impedance ones. ZTE Axon 7 also does not set records, but under similar conditions its output level was recorded at 305.7 mV.
When testing the quality of audio output in the Right Mark Audio Analyzer 6 (hereinafter referred to as RMAA) package using an external E-MU 0204 USB sound card, the final rating of “very good” was obtained. The signal-to-noise ratio turned out to be very high, the dynamic range was wide, but the frequency response in the high-frequency region turned out to be a little overwhelmed. However, I personally was not able to notice this blockage even when using high-quality monitor-type headphones.
General results in the packageR.M.A.A.
Performance
The smartphone is based on the Qualcomm Snapdragon 617 system-on-chip. This is a 64-bit 8-core solution based on the 28 nm LP process technology. 4 Cortex-A53 cores operate at a frequency of 1.5 GHz, and the second quartet, based on the same architecture, operates at a slightly lower frequency of 1.2 GHz. The video subsystem is based on Adreno 405. We tested a version of 3 GB of LPDDR3 RAM operating at a frequency of 933 MHz, and 32 GB of permanent memory.

The following smartphones were taken as opponents: Moto M (MediaTek Helio P10), ZTE Axon 7 (Qualcomm Snapdragon 820), as well as Moto G4 Plus, based on the same system-on-chip as the tested smartphone. System performance was measured using synthetic PCMark, 3DMark, Geekbanch 4 and AnTuTu v6. Memory speed was assessed using the AndroBench application.
Testing was also carried out in cross-platform javascript tests (Mozilla Kraken JavaScript and SunSpider). The results of these tests significantly depend on the browser used, therefore, to minimize the impact, Google Chrome will be used in all reviews, as the most common one.
Camera
The front camera has a resolution of 8 megapixels with an f/2.2 aperture. Apparently, the sensor size is small, so the quality of pictures in low light is very mediocre, and this camera is not suitable for taking “selfies” at dusk at all. In good lighting or when shooting outdoors during daylight hours, the pictures turn out to be quite tolerable. Among the features, we can note the smile detection mode, but it only works when the teeth are at least slightly noticeable, and the automation is not able to detect a slight smile. There is also a “retouching” mode indicating the level of activity, but all processing comes down to the usual blurring of an already blurry picture.
The main camera is 16 megapixels with an f/1.9 aperture, which is slightly better than most comparable devices. It is worth considering that shooting with maximum resolution is done with an aspect ratio of 4:3, and for the more usual 16:9 ratio, the maximum resolution is 12 megapixels. In Pro mode, you can manually change the shutter speed, sensitivity (ISO 100-1600), exposure correction, select a white balance setting, manual focus and set the interval shooting step from 1 to 60 seconds. As with the ZTE Axon 7, auto mode HDR shooting works extremely rarely, so if there are areas in the frame with a large difference in brightness, it has to be activated manually. Upon closer inspection of the flash module, which consists of two LEDs, it is noticeable that it differs from the flash module of the older model. This guess was confirmed by measurements - at a distance of 1 meter, an illumination level of 20.1 lux was recorded, while the flash of the flagship under the same conditions provides an illumination of 60.1 lux, which is currently a record among the smartphones we tested.

Transferring camera control using the Camera 2 API is impossible, just as shooting in RAW is impossible, so measuring the noise level of the matrix is essentially pointless, because when saving in JPEG, the software noise reduction is too aggressive. To evaluate image quality, a test pattern was captured with all available sensitivity values. Below are cropped fragments.

ZTE has never released smartphones that could compete with the main flagships on the market. The situation changed when the ZTE Axon 7 and the “junior” model with the “Mini” prefix were introduced. The release date of the devices is 2016. Just like its older brother, the ZTE Axon 7 Mini is one of the best music smartphones in the market.

Video
Appearance and design
The body is made of metal with small plastic inserts for antennas on the rear panel. The first thing that catches your eye in comparison with the Axon 7 is the absence of touch control keys and a different speaker grille pattern on the front side of the smartphone. The side edges are rounded on both sides.
After turning it on, it becomes clear that the phone has wide frames on the sides. Above the display is the front camera
The device is well assembled and does not creak when compressed. The rear panel houses the main camera module, flash and fingerprint scanner. The lens sticks out, and the scanner does not always respond clearly to pressure. Axon 7 Mini is available in 3 colors:
- Grey.
- Gold.
- Platinum.
On the right side there are volume buttons and a lock key.
On the left is a hybrid connector into which you can insert either two Nano-SIM format SIM cards, or one SIM card and a MicroSD memory card
The microphone and USB Type-C connector are located at the bottom
On the top edge of the smartphone there is an additional microphone and audio jack.
The dimensions of the device are 147.5x71x7.8 mm, and the weight is 153 g.
Display
The smartphone is equipped with an AMOLED screen
The diagonal is 5.2 inches, and the resolution is 1920x1080 px. The pixel density is 423 ppi. There is also an oleophobic coating. Despite the presence of protective glass Gorilla Glass 4, there is no escape from a large number of small scratches.
ZTE Axon 7 Mini received a “Gloves” mode. After its activation, the screen responds to touches when wearing gloves, but high sensitivity leads to a large number erroneous clicks.
The automatic brightness adjustment mode works correctly
In the sun, the information on the display is clearly visible, but the colors are slightly distorted. The AMOLED screen provides rich blacks and a wide color gamut. The image is cool, bright and contrasty, which is typical of AMOLED. In the settings, the smartphone owner can independently adjust the color saturation and hue.
Software
Axon 7 Mini runs on Android 6.0.1 OS with the MiFavor UI shell installed, which has long been one of the most unfinished. But in version 4.0 the developers fixed it.
MiFavor 4.0 is not much different from other shells that are installed on Chinese devices. You can see similarities with Huawei's Emotion UI. All program icons are located on the desktop, however, while in Emotion UI 5.0 you can enable the menu in the settings, this option is not available in the Axon 7 Mini.
The smartphone has an application for selecting themes and . If you use a password to lock your phone, the wallpaper will not change. Also, after blocking, applications are suspended. After unlocking, a widget appears asking you to stop running programs. For this reason, applications do not synchronize after blocking, as a result of which notifications about incoming emails may not arrive regularly.
Of the pre-installed applications, note the presence of WPS Office and Accuweather widgets. Despite the fact that the developers cut out a number of functions of the flagship model, the shell interface remains beautiful.
Sound
This is the main trump card of the hero of the review. Axon 7 Mini was designed as a relatively inexpensive smartphone with high-quality sound in headphones and speakers. Stereo speakers located on the front panel are capable of producing high-quality and loud sound without distortion, even in extreme modes.
The second specific feature of speakers is volume. The Axon 7 Mini is capable of demonstrating cinematic sound reproduction techniques. In order to appreciate the beauty of stereo speakers, several demo videos are recorded by default. To feel the beauty of sound, the smartphone should be located no more than an arm's length away.
Listening to music on headphones, you can notice defects even in those audio files that were previously considered ideal. A discrete sound processor is responsible for sound purity.
Performance
Android 6.0, eight-core Snapdragon 617, Adreno 405 video accelerator, along with 3 GB of RAM and 32 GB of internal memory contribute to the high performance of the device. The chip was developed in 2015 and was installed on mid-range phones. Over time, they began to equip budget devices price segment, so its presence in the Axon 7 Mini cannot be called an unexpected decision. The developers could have supplied a more powerful chip, but in this case the smartphone would have been in a different price category.
Octa-core Snapdragon processor 617
The creators have worked on optimizing the system and eliminating freezes that occurred in the previous version of Axon Mini. Although the Snapdragon 617 is a strong processor, it is already outdated. Its speed is enough for comfortable work in the browser, but you can’t play games with high detail.
Camera
Front-camera
The main camera of the phone is capable of recording video in Full HD format. The application installed by default has a number of settings that will appeal to both those who want to customize everything at their own discretion and ordinary users.
There are several photo modes:
- Pro mode.
- Long exposure.
- Slow motion.
- Live Photo mode.
- Quick shot.
In good lighting, in the hands of a master, the smartphone is capable of taking high-quality pictures
Autofocus is fast in most cases, but macro photography can be problematic.
In poor lighting conditions, the camera focuses within a couple of seconds, but in the dark the Axon 7 does not take high-quality pictures.
Battery
The battery capacity is 2705 mAh. This is a low figure, but the disadvantage is compensated by support for fast charging.
The Snapdragon 617 is considered an energy-efficient processor, but the battery capacity is not enough for long-term intensive use of the smartphone without additional charging. The ZTE Axon 7 Mini will work for 3-4 hours in games, and you can watch videos for 8 hours. On average, the battery charge lasts for one day of normal use.
Detailed battery usage
Advantages and disadvantages
Despite the fact that the Axon 7 Mini has lost a number of functions compared to the flagship model, it has retained its advantages. If design, AMOLED and screen diagonal are among the subjective advantages of the device, then the phone also has objective advantages
- Metal body.
- USB Type-C.
- High quality sound.
- Availability of a fingerprint scanner.
- Availability of a headset in the delivery set.
- Fast charging support.
- 3 GB RAM and 32 GB internal memory.
- Weak battery.
- Unstable 3g operation.
- Increased display sensitivity in Gloves mode.
- Price.
- Fingerprint scanner malfunctions.
ZTE Axon 7 Mini is a good smartphone with its advantages and disadvantages. What makes the device unique is that it is one of the best multimedia phones on the market. The main disadvantage of the review hero is the price.
Any smartphone can function as an MP3 player, but if high-quality sound is important, then ZTE has practically no equal.
A separate Asahi Kasei AK4962 audio chip is installed here, to which software support for Dolby Atmos technology and stereo speakers has been added. Watching demo videos convinces that the developers’ efforts were not in vain. The surround sound effects are impressively rich and spacious.
You can enable Dolby support in your video player, as well as when watching movies in popular online cinemas and on YouTube. With it, the sound becomes rich and goes beyond stereo, becoming three-dimensional.
The speakers themselves are quite loud, and feel one and a half times more powerful than many smartphones in this price category. At the same time, the sound is quite clear, without wheezing or distortion at maximum volume levels.
However, the bass is a little lacking, which is logical given the thickness of the smartphone. Their deficiency is compensated by the amplification and detailing of mid frequencies, which overall gives a good picture. There are, of course, more bassy models, but there the sound becomes like a muffled mumble, in contrast to the detailed sound of the Axon 7 mini.
Listening to music in inexpensive branded monitor headphones also gives the right to talk about high sound detail in the mid and high frequencies. Suddenly, instruments appear in recordings that you had not previously noticed, and shortcomings in tracks that were invisible when listening on other smartphone models may also appear.
If you think about your competitors, the first thing that comes to mind is the musical Meizu. But they are simpler: the audio chip is different and the speakers are weaker. Alcatel Idol 4 also looks dull compared to the Axon 7 mini. For A-brands like Samsung or Apple, sound is given secondary importance, since manufacturers believe that the average level is quite enough for the mass market.
In terms of picture richness - one of the best
The AMOLED matrix on organic light-emitting diodes with a diagonal of 5.2 inches and a resolution of 1920x1080 is very good. It will especially appeal to fans of bright, rich and contrasting screens. It is more colorful and richer than more common IPS matrices.
If desired, this riot of colors can be muted a little with settings that allow you to make the image a little warmer and softer.
The screen has a great oleophobic coating, fashionable rounded edges of Gorilla Glass 4, called 2.5D, and excellent sensitivity. You can work with it even with thick gloves, if you first enable the option of the same name in the settings in the “Personalization” section.
But what can really upset you a little is the low maximum brightness. In direct sunlight, it will be difficult to operate your smartphone.
Asking about viewing angles for AMOLED matrices is bad manners. The image looks great from any direction and at any angle.
Original design and slippery body
Looking at the front side of the device, it is almost impossible to confuse it with others. The rounded edges of the newfangled 2.5D glass and decorative mesh the top and bottom covering the stereo speakers make it stand out from others.
But look at the reverse side, and you can no longer distinguish it from a number of other models, although the design was worked on by Designworks, a company part of the BMW group. However, “similar to others” does not mean bad. It's just that famous designers could be more original.
There are three colors on sale, one of which is much cheaper. The silver and gunmetal options look good, but the metallic pink bezel, made of textured aluminum, suddenly starts to feel like it's made from cheap plastic. The reason is the paint, which is simply not suitable for this type of surface.
The back cover is also aluminum and quite slippery. The only thing that saves the situation is the transparent case that comes with it.
The fingerprint recognition sensor is very convenient to use. It works almost instantly, but in about a third of cases it works on the second try. To avoid this, you have to apply your finger as evenly as possible.
Not a bad camera
The main camera in the Axon 7 mini will appeal to most owners. She makes almost no mistakes in white balance, she manages to take excellent night shots, she has accurate color rendition and works well in difficult conditions.
The main problem of the camera is the mediocre detail of the images, which, however, suffers from 95% of modern smartphone cameras. The lens also slightly distorts the geometry, so objects with straight contours running across the entire frame are best placed in the center.
Despite the aforementioned shortcomings, the ZTE's camera leaves a positive impression. Particularly impressive is the night mode, which uses a mechanism akin to HDR. The frames are obtained without dark spots and graininess.

The front selfie camera is the complete opposite of the main one. Its optics greatly distort the geometry. Almost all frames have overexposed areas, and post-processing algorithms blur out all the noise along with the details. Selfie fans - this is not your smartphone.
The quieter you go, the further you'll get
To maintain a distance from their main flagships, the developers equipped the Axon 7 mini with an average-performance Qualcomm Snapdragon 617 chip. This SoC with eight Cortex-A53 cores went into production about a year ago. In Axon 7 mini, the first four cores operate at 1.5 GHz, the others at 1.2 GHz.
In all tests, it shows the lowest results in comparison with competitors from the same price niche.
But don't rush to bury him. Firstly, the demonstrated performance is more than enough for most modern games and applications. Dead Trigger 2 and Asphalt 2 with maximum settings run on it without any visible slowdowns. The OS interface runs smoothly, and all applications open at about the same speed as on competitor devices.
Secondly, the chip does not overheat. During prolonged high loads, the temperature of the chip does not exceed the established limits, after which the system can slow down its operation. While for the more powerful Xiaomi Redmi Note 4 and Meizu MX6, after just 6-8 minutes of running the GFXBench test, graphic performance drops by 2-3 times, falling below the level of the Axon 7 mini.
In addition, the presence of three gigabytes of memory, which today can be considered slightly redundant, will not allow the smartphone to “sour” in 2-3 years, when more resource-intensive applications appear.
Battery is weaker than competitors
In terms of autonomy, the Axon 7 mini demonstrates low results for its class. This is quite expected, since its battery capacity is about 10% less than that of most competitors. At the same time, it’s disappointing that the AMOLED matrix does not make it more economical.
In a loop Subway game Surfers it lasts 3 hours 45 minutes, and can play Full HD video from a memory card for up to 7 hours 45 minutes. This is 20 and 15 percent less than the same HTC 10.
If you watch Full HD video from YouTube via Wi-Fi using a proprietary application, then the viewing time, in comparison with the file, will be reduced by an hour to 6 hours 40 minutes. Overall it's not bad, but I would like more.
Quick Charge 2.0 fast charging technology does its job properly: up to 80% of the smartphone is charged in 50 minutes, and fully charged lasts exactly one and a half hours.
Opinion site
The developers have done their best: the Axon 7 mini has a rich screen based on an AMOLED matrix, excellent sound for a smartphone with support for Dolby Atmos, which makes watching movies more atmospheric, and a high-quality camera with a good night mode. And if there was a Snapdragon 821 SoC here, then it could be placed on the same level as flagships and ask for a much more impressive amount for it than the 24 thousand rubles that it costs now.
Accelerometer(or G-sensor) - sensor of the device’s position in space. As a main function, the accelerometer is used to automatically change the orientation of the image on the display (vertical or horizontal). Also, the G-sensor is used as a pedometer; it can control various functions of the device by turning or shaking.
Gyroscope- a sensor that measures rotation angles relative to a fixed coordinate system. Capable of measuring rotation angles in several planes simultaneously. A gyroscope together with an accelerometer allows you to accurately determine the position of the device in space. Devices that use only accelerometers have lower measurement accuracy, especially when moving quickly. Also, the capabilities of the gyroscope can be used in modern games for mobile devices.
Light sensor- a sensor thanks to which they are installed optimal values brightness and contrast for this level illumination The presence of a sensor allows you to increase the battery life of the device.
Proximity sensor- a sensor that detects when the device is close to your face during a call, turns off the backlight and locks the screen, preventing accidental clicks. The presence of a sensor allows you to increase the battery life of the device.

Satellite navigation:
GPS(Global Positioning System - global system positioning) is a satellite navigation system that provides measurements of distance, time, speed and determines the location of objects anywhere on Earth. The system is developed, implemented and operated by the US Department of Defense. The basic principle of using the system is to determine location by measuring distances to an object from points with known coordinates - satellites. The distance is calculated by the delay time of signal propagation from sending it by the satellite to receiving it by the antenna of the GPS receiver.
GLONASS(Global Navigation Satellite System) - Soviet and Russian satellite navigation system, developed by order of the USSR Ministry of Defense. The measurement principle is similar to the American GPS navigation system. GLONASS is designed for operational navigation and timing support for land, sea, air and space-based users. The main difference from the GPS system is that GLONASS satellites in their orbital motion do not have resonance (synchrony) with the rotation of the Earth, which provides them with greater stability.
