To us for review was one of the best camera end of 2018 Huawei Mate 20. Feature of the smartphone become a triple main camera with optics from the German company Leica, and advanced algorithms of image capture and post-processing on the basis of AI.
In 2018 Huawei Technologies Co. Ltd. became took first place in the world among manufacturers of smartphones. Leadership as reflected in number of units sold worldwide, and the level of financial savings, allowing the company to compete with such corporations as Samsung and Apple. Huawei resorts to relatively aggressive advertising, confronting their rivals. At the same time, the company does not hesitate to pick up the last trends of competitors, like “bangs” and artificial intelligence. But that does not stop Huawei to move away from copying other manufacturers, and design the devices.
In the Russian market share of Huawei in 2018 reached 17.4% and is rapidly gaining momentum, thanks to the release of the best in terms of prices and characteristics.
Huawei works closely with China — the government strongly supports the company. Huawei has become difficult for the largest manufacturer of smartphones, is a conglomerate with sub-brands and different branches. For example, the company is also engaged in network communication and production of audio-video equipment. Huawei also invested in nanotechnology and neural networks.
Ergonomics and appearance
Okay, let’s review the Huawei Mate 20. The casing consists of a polished glossy glass and metal frame. At first glance the device can slide into the palm of your hand, but in practice this is not a smartphone lies in the hand like a glove. The phone fits perfectly in the palm of his right and left hand thumb falls exactly on the button “Food”.
The fingerprint scanner very well placed on the back side — easy to reach with the index finger blindly. This is a rare case in the camp of Android devices where hidden on the back surface of the sensor is not always possible to find the first time.
The backlash of the hull is missing, as well as “pohrustyvaniâ” when pressed. Colour marketing name model that came to us for review, “the twilight color”. The appearance of small scratches in the coating possible, but it is unlikely that they will be visible even under close inspection. However, without a complete case to carry a smartphone is not necessary — from a small palm so big the camera you can still drop, and a beautiful glossy surface very easily soiled and quickly collects fingerprints.
Important point — the new design is no confusion with the positioning of a smartphone in space. Many devices have problem — if the gadget is to take the night, to the touch it is difficult to understand where the top and where the bottom of the device. But due to the ribbed power button and the bezel frame of glass in which are hidden three cameras and one flash to the wrong position Mate 20 will be difficult.
The device is “lies” in the horizontal mode, allowing no tension to keep the brush case is ideal for those who like to view web content, or reads books. The smartphone is convenient to use Yandex. Browser, which the search string is at the bottom.
At the top, in a small cutout on the display, “hidden” front camera. There is also a LED indicator for calls and notifications — it is small, neat and has some color and is not distracting. “Bangs” on the screen does not prevent the use of smartphones. Moreover, when using a dark background image creates the impression that “cut” does not.
The smartphone comes in a black matte box in the middle of which is the inscription “HUAWEI Mate20” and an indication of the use of triple camera with optics brand Leica.
Inside the box is covering the smartphone, the unit with a translucent silicone case, earphones, USB Type-C wire and key for SIM card tray.
It’s nice that with some time, almost all “Chinese” are used in the delivery of simple, but still protects from drops the bumper. Unfortunately, almost all cases are pretty cheap and acquire over time a yellowish tint. In any case, still nice.
Power adapter supports SuperCharge that can charge your smartphone to 100% in less than an hour. However, we note that it is fraught with rapid battery wear.
I am glad that brands like Huawei and Xiaomi, care about the consumers, providing them for the first time all elements of the accessories.

Huawei Mate 20 comes with software called build number 18.104.22.168 on immediately updated to the latest version. Firmware smartphone runs on the Android operating system 9.0 and as the shell is used EMUI 9.0.0.
The system is focused on gesture control and just “beat” the desire to use a smartphone with a physical and virtual buttons.
Huawei wants to avoid a hard peg to Google by promoting your individual account with such important functions as “Cloud”, “Password account”, “Center of protection”, “Payments and purchases” and “device Manager” where you can disable the operation of applications. Account Huawei is a function of “Protection account”, where you can use two-factor authentication.
EMUI — shell, which is based on the Huawei Mate 20 consists of desktop pages, which are downloaded programs. A separate menu, as such, is not here.
The leftmost tab is used to control the “Google Search” shows the latest and popular news, including and subscribed user via its own Google account. Those who will interfere, you can remove/stop system application, but in no case shall not update them through Google Pay — otherwise they will turn on again.
The drop down notification list is typical of the Android operating system:
Standard keyboard in landscape mode looks a little thick, it takes quite a lot of space, but it allows to correctly write messages or notes on the go:
Menu “Settings” is reminiscent of the menu from iOS. For example, tabs have labels, and the settings are split into several paragraphs. At the top there is a tab log in to your own account Huawei, and located above search form on the setting items.
The system of creating screenshots similar to iOS 12 and displays made screenshot at the bottom left of the screen, and after clicking on the image opens the image editor. This “trick” all of the Android operating system 9.0 — the use of it causes a sense of deja vu when you abruptly transition from iPhone. Blame Huawei, and Google to copy I don’t want to, but it’s a fact. And in the future it is not necessary to pay particular attention to these operating systems more than 10 years of existence, has absorbed the best model of usability.
At the bottom tab “System” option is “Easy mode” including “grandma’s” desktop interface, allowing people with low vision or older generation, simple and easy to operate with the basic functions of the smartphone. As for me, made this point in an awkward place and find it immediately almost impossible.
More recently, manufacturers added to their smartphones mode called “Digital welfare” or “Digital balance.” Original profile name — Google Wellbeing. In fact, it is a toolbar, which tracks the habits of the owner of the smartphone, allowing you to control the startup and operation of applications in the background. In Huawei Mate 20 this parameter is divided into “Battery” and “Digital Balance.” Their division looks inappropriate — in fact, they are two identical functions that are redundant.
The desktop environment looks a little “toy”. The icon is drawn without the frills and you have a discrepancy in size between the system and third party software. Yes, you can change the theme, and the launcher, but the system shell by default doesn’t seem as nice as on other smartphones.
And the iPhone X line, this device is focused only on gestures. The control system should be used. Unlike iOS, where it takes a couple of hours, the Mate 20 the process can take up to several days. For example, to return back, you need to swipe to the side. The left — back and exit the application, right — forward and also exit programs by double sliding fingers. For example, in the browser, this move allows you to move through your open pages of the tabs. Huawei as clearly as possible trying to please the users, giving a maximum range of options. Not to say that it came out very easy, but takes time to get used to. The era of buttons, it seems, has passed and a new stage in the development of mobile operating systems (expect touch-sensitive buttons control volume and power!).
I definitely do not like is the “full backup” with iPhone X swipe gesture from the bottom up, which opens the multitasking running applications and acts as the virtual “Back” button and “Home”. How else, you ask? It is the most intuitive gesture for human mind. To circumvent which has become already a norm of action, it is meaningless. The only difference from iOS is not used in Huawei white stripe for visual cues on how to perform the action. To complete to start using the shell EMUI, you need to have experience in managing iPhone series X.
In this review, it is not necessary to pass the built-in apps Huawei. They are quite comfortable and refined. It is noteworthy that some brands of services from ecosystems Huawei begin with the prefix “Hi” — a kind of analogue chips for Apple, which used almost all the names of their products started with the prefix “i”.
HiSearch is analogous to the Spotilight of iOS, and looks almost identical. The drop-down list from the search string contains four recommended apps that were running previously, and is frequently visited. In HiSearch you can search for contacts, applications and calendar events.
The app “Themes” much like the analog of the same program on Xiaomi. The application has a filter by category, rating, collections. There is a history of the use of certain topics. The app fulfills its function and does not cause the desire to put a third-party launchers.
Another system application is the “Manager phone” — now an analogue of this program is on almost every smartphone with Android. The program performs various optimizations, closes unnecessary background processes and clears RAM.
I want to also mention not as necessary, but still interesting applications. For example, the standard “Music” supports Dolby Atmos and allows you to set as a ringtone the current track.
Huawei is a Health tracker that tracks the number of steps. The tab “Exercises” allows you to perform tasks training. You can divide them into walking, running, Biking, and to develop training plans and all this is accompanied by the voice assistant, though in the English language.
“Virtual remote control” — a program that allows you to use the IR port to the smartphone as a TV remote.
HiCare — independent performance monitoring components. Use the diagnostics and search for current information. It is possible to find the authorized service center in the city where you live. There are also tips and recommendations on working with your smartphone.
“Phone Clone” — the transfer of information from your previous device to Huawei. Supports transfer data from iOS.
“Mirror” — turns the smart phone into a mirror using the front camera.
HiSuite — backup and recovery. You can create backup data on any external storage device: memory card, USB drive, FTP. Or on a personal computer using the program.
Hardware-based and display
Platform Mate 20 is a powerful system-on-chip of its own production Kirin 980, with a dedicated neural kernel, network interfaces and memory in a modern format high capacity.
The processor is divided into three clusters and two additional sub-cluster, a total number of eight cores (2×ARM Cortex-A76, 2.6 GHz + 2×ARM Cortex-A55, frequency of 1.92 GHz + 4×ARM DynamiQ, 1.8 GHz); architecture HiAI. Included two modules neural computing NPU (Neural Network Processing Unit). Kirin 980 uses an architecture Big+Middle+Little. Not difficult to guess that the role of the Big acts A76 2.6 GHz, Middle takes on A-76 1,92 GHz, and uses Little A-76 and A-55 1.8 GHz in a clustered ARM technology DynamiQ.
The platform itself contains 6.9 million transistors and is fabricated for 7-nm process technology, that allows significantly to reduce power consumption and heating of the chip in complex tasks. Nominal frequency of the CPU is 25 degrees.
AnTuTu shows us the following data:
Evaluation 272678 points does not seem grandiose, but it’s more than in the same iPhone 8, where the result is 201000 points.
In the benchmark Geekbench 4 the result is in single-threaded mode 3367 and 10037 to multicore. The same 8 iPhone wins in single core test with 4537 points, but loses in multi-core, picking up 8975 points.
As this synthetic test, we therefore expect them credibility is not worth it. On the case — Huawei and has a slightly retarding the throttle, while the iPhone 8 is practically not heated, although the A11 chip Apple chip is produced by a 10-nm process technology.
Neural network (NPU) is only responsible for the processing of the photos and video. For example, UHD 4K videos are optimized for the best quality content, and electronic stabilization selects the correct focus point and exposure. In Huawei Mate 10 using the first version of the chip, whereas in the Mate 20 new NPU faster than the previous 46%.
Memory is represented by 16-bit modules LPDDR4X with a clock frequency of 2133 MHz working on a multi-channel memory architecture Quad Channel. In General terms, here 6 GB. In idle state consumes almost half of RAM and an additional swap file ZRAM takes less than 600 MB. However, this is a pretty good score for an Android device.
As a permanent store is memory standard UFC 2.1. The flash drive pretty fast. For internal storage using a file system f2fs format. It was developed by Samsung Corporation and optimized for eMCC drives and for future SSD. It is divided into streams /data and /system. The last option is only storage of the Linux kernel and is 4.5 GB of which is occupied 3.8 GB. Section /data contains all other files, including those added by the user. Of the announced 128 GB appears only 108 GB, employing more than 7.9 GB user available a little more than 100 GB.
Li-pol (lithium-polymer) battery has a nominal temperature of 29 degrees, and the stated capacity of 4000 mA*h. the Main advantages of this type of battery:
A large energy density per unit mass;
The thickness of the elements from 1 mm;
The opportunity to obtain a very flexible shape;
No memory effect;
A slight voltage drop as the discharge;
The operating temperature range of Li-polymer batteries are pretty wide: -20 to +40 °C according to manufacturers.
Despite these specifications, Li-pol, every battery starts to wear out, losing their capacity and gradually vadovas.
Mate 20 is charged from the Power Adapter 2 to 5 amps, which in theory allows you to charge the flagship in 50 minutes. In practice, the charging time was 1 hour and 20 minutes, but the smartphone was used and was constantly included Wi-Fi, NFC and Bluetooth. As usual, up to 50% the battery is charging fast and then slower.
Display Huawei Mate 20 has an aspect ratio of 18.7:9 with a resolution of 1080×2244 (FHD+). The size of the screen is 6.53 inches, and the type of matrix TFT LCD (IPS). The point density is 381 ppi which is quite low. Used 2.5 D Corning Gorilla glass 3. The brightness level is high, and its peak value is 510 CD/m2 at normal (room mode) and up to 800 CD/m2 on the street.
Display — not the most expensive component of a smartphone. This is evident in the small yellow image, which is highly visible at night. Any flashes of the screen is missing, but the white color strongly deviate from the true value. Installed anti-glare screen coating designed to protect from direct sunlight, at an acceptable level. Oleophobic coating is also of good quality and allows you to easily move your finger across the screen.
Uses the following interfaces: Wi-Fi (802.11 a/b/g/n/ac, 2.4 GHz/ 5 GHz), Bluetooth 5.0 (support BLE, SBC, AAC, aptX and aptX HD, HD LDAC and HWA Audi), NFC, GPS, Glonass, Beidou, Galileo. 4G/LTE supports the following Band: 1 — 9, 12, 17 — 20, 26, 28. Use two slots for SIM-cards format NanoSIM, and either one SIM, or one nanoSD card.
A memory card is a proprietary format nanoSD (Nano Memory Card or NM Card) — a serious drawback of the model. In the free course it in Russian nowhere. To purchase this card type can only have the Huawei that, for a moment, will cost 6,000 rubles. Moreover, for such maps there is no adapter, hence you will not be able to connect separately to your computer. The transition to a proprietary format, as it likes to make Apple devices, may result in the collapse of Huawei.
As the size of the nanoSD card is identical with the size of the Nano-SIM in the same slot can be used as a “SIM card” and the SD card. NM Card 45% less than microSD. Pleased with a top peak speed reading nanoSD — up to 90 MB/s.
4G/LTE network catches confidently and almost always reflects the full scale of the fill signal. Sharp drops in connection do not exist. There is the presence of the IR port for normal control and built-in appliances.
Huawei Mate 20 has two stereo speakers. Supported standards: aptX, aptX HD, LDAC, HWA (Hi-res wireless audio) and Dolby Atmos. Out of the box smartphone works with flac, ogg, aac.
Sound Mate 20 very clean. The dynamics are so properly transmit the sound, if you listen to the audio recording in a closed Studio space. However, speakers have serious penalties with the bass: clear bass is simply absent and after 2-3 minutes, the person who understands a little about music will understand that a track is played is relatively flat. And yet, the Mate 20 the impact metallic echo that, of course, does not paint the mobile.
To check the sound in the earpiece was used brand Monster Ispiration off the noise reduction. The headphones sound is also very clean, but the problem with the bass frequency has not disappeared. Headphones that come in the kit, can be used as main. They are the same quality as analogues for 900 rubles, and I see no reason to change them for a different model. The headphones have a MIC on their control panel you can switch tracks or decline the call.
Yet, despite the disappointments with the bass, I would recommend a smartphone for music lovers.
Front camera resolution Huawei Mate 20 is 24 megapixels with a f/2.0 aperture, the lens size is 26 mm. But despite the flagship features, front camera Mate 20 has the best results for their characteristics.
The photo with the front camera there is digital noise, sometimes noticeable artificial blur, reminiscent of the bokeh effect. Missing stabilization and autofocus. The worst thing is that a selfie with Mate 20 (second photo) is inferior to Nokia 7 Plus (first photo):
And although the photos themselves were taken in different conditions, in the photo with Mate 20 is clearly noticeable the lack of sharpness, image clarity, poor focus and prohibitive for such sensor noise.
The main camera
The main camera has dvuhtonnoy the camera, optics, Leica and three lenses: 12-Megapixel wide angle lens (f/1.8, 27mm) + 16-Megapixel ultra wide angle lens (f/2.2, 17 mm) + 8 Megapixel telephoto lens (f/2.4, 52 mm).
The camera has the following modes:
“Aperture”, with the regulation of the strength of the blur, or automatic control;
”Night,” with a high ISO level and shutter speed;
“Portrait” — simulation of the bokeh effect when capturing “live” person;
Standard Photos with bracketing;
“Pro” manual control of ISO, shutter speed, exposure, focus mode (accessible to AF-S, AF-C, MF) and color temperature.
An additional tab “More” includes the modes:
“Augmented reality” (similar to Animagi iOS);
“Light” (colour balance);
HDR (deep contrast);
“Period of time” (increased playback speed);
“3D-panorama” (chetyrehrazovoe overlay of images taken in a circle and from top to bottom with beaty-effects);
“Watermark” (text overlay on the image);
“Documents” (documents analysis, adjustment, and export to office applications);
“Download” (download more modes if they are available; it is assumed that they will be added).
We decided to compare photos without using light filters in RAW mode (with professional tools), HDR and photo in manual or auto focus.
Warning: RAW photos Huawei are clipped to 5 MB manual or automatic converters, in order not to “burden” the site more weight files.
Of course, first make a photo with the bokeh effect using the portrait mode:
To write that this is a masterpiece, don’t say anything. Portrait of “buddies” made of brass so bright and expressive, that I want to believe that I shot this photo on an SLR camera. Perhaps a professional photographer and will find flaws, but for the layman, for the fan to remove the mobile camera, the result seems to be something extraordinary.
This ultra-wide-angle photography, which captures 30% more outside the frame elements:
In normal cells the loss of sharpness and noise level can reach up to 30-35%, but Huawei with software tweaks were able to reduce this percentage to 5% in the daytime and in the evening — not more than 15%.
Example 2-fold increase in frame using zoom software:
Almost no noise, the triangle of exposure (ISO, aperture and shutter speed) are on stable parameter. However, in the automatic mode, noticeable some loss of sharpness, but the photo is too zasvecheno. But it is fair to consider the size of the matrix from which “pulled out all the power.” And nobody cancelled a Pro to set everything yourself.
An example of the second snapshot, where the lack of optical image stabilization, combined with the trembling of the hands and the corresponding high quality zoom:
The following picture shows the main 12-Megapixel camera is barely noticeable preshaping and increases the dynamic range with smooth loss of quality when zooming images:
Most of the work takes the focus, which at the edges is characterized by a decrease in the amount of sharpness and “soapy” flavor. Moreover, almost always need to be configured manually selecting the correct area of focus, not to lubricate.
The next frame illustrates the Galician stadium in the same Park:
The image in the RAW format shows the correct white balance and correct shade of the grass with the sky. Excellent and unobtrusive Scharping, which does not spoil the overall quality.
The use of a telescopic camera with a resolution of 8 megapixels and twice the optical zoom:
Far plan there is a slight deterioration, but near the received frame does not lose small parts.
The effect of the Panorama a no apparent bonding of frames and has smooth transitions throughout the area of the photograph:
The neural network used in the camera, are responsible for more precise settings of the diaphragm, autocoherence on the desired object, white balance and even light. However, computing the camera work is not as established as we would like, so it’s best to use manual settings.
Autofocus has multiple types of capture: phase, laser and contrast. For clearer indicator HDR-picture involves the calculation of depth of field, again, closely linked to neural computing.
Test the photo capabilities
Examples of images we will present below and the XR compare to iPhone with just one lens.
Shot a frame in RAW format. Highest quality, optimally matched exposure, resulting in visible the full picture, low and unobtrusive Scharping, absence of defects and high, sometimes excessive, depth of field:
iPhone XR took a picture of the frame in TIFF format. Visible automatic selection focal, range sharpness is at an acceptable level, color balance is slightly elevated:
Keramo-granite wall in the Park of the Galician. Here Huawei has surpassed himself. Perfect balance and excellence of detail:
iPhone XR as always overestimated the brightness. Sharpness is at a good level, slight sharping in the sky, turning into a small image defects:
And again Huawei Mate 20. A quiet, normal picture. No oversaturated colours. The usual sharpness away multiple defects. The light is at entry level ISO 160 without gross perenasytil:
iPhone XR again shows persistent filtering, which includes an increase in brightness, but with a balanced field even in the background. Photo more dynamic and intuitive features to yourself:
Summary: if you compare the camera of my personal “budget” iPhone XR with Huawei Mate 20, it is possible to draw several conclusions. First Huawei Mate 20 takes just a great photo! He tries to display the maximum amount of detail. The second is a valid transfer of a digital image of a realistic world as it really is in reality. And, third, neural networks are know their stuff. Daily maintenance of the neural processor post-processing the final image, depending on the focus and weather conditions, at 90% true.
Of the minuses I note the “raw” NPU — I would like to remove from the received explicit scenes moments blur and get a better image when zoomed.
Then you can estimate the photo with Mate 20 without our insights.
The amphitheater of the Park of the Galician:
Ryan Agricultural institutions:
The same shot, just cropped:
Ultra-wide format area of the Drama:
Similar format on the other hand the same place:
I own persona:
And this is a formal OZ Mall:
The grass field near the Administration building:
Apartment building and Playground in a residential area of Jubilee mikrorayna:
As we can see to remove in the morning and afternoon, the Huawei Mate modules 20 are excellent. But toward evening, the picture quality becomes worse. And then compare with the iPhone XR becomes useless.
Summary and conclusions
Huawei Mate 20 is considered to be one of the best camera phones on the market, and also has a powerful “iron”, which gives a reserve of performance for several years to come. However, it is not without its flaws: the camera of your smartphone at night is very noisy, the shell .. not working so smoothly as it would like.
On the other hand, you can not miss such important features of a smartphone like convenience and design. Gradient color does not look cheap, and the case did not scratch, no matter how we tried.
And the main feature — various settings of the camera for all occasions. Whether it’s a portrait mode or a normal format camera allows for virtually any position of the user, allowing you to capture the colorful scenery of the mountains and to do a quality photo in the rhythm of the city. With Huawei Mate 20 want to spend more time than a few hours. Manual setting of exposure and aperture, HDR, panorama, filters, and format ultra-wide-range image capture — all will not get bored imagination of a future photographer on such a larger and high-quality screen. It is not a slogan, but rather a pleasant feeling when you want to paint a picture that can machine that you like. Huawei Mate 20 — a great step forward for the Chinese company.
It is immediately evident that Huawei is trying to control software and technology, like Apple. At the same time, the Chinese company listens to its users. Huawei tries to take the competition to have the most current technology, but uses them differently. The development of its unique and unusual software environment is too expensive and long activity that is unforgivable in our time. And to take from others is not considered “stealing” is a kind of complex of measures that allows to survive in the market and make their products relevant to the users and to offer it at the right price.
High quality images in the morning and afternoon;
Huge selection of various settings, modes, and light filters cameras;
A huge screen with a small size of the device;
Great sound with Dolby Atmos;
Convenient to both the form factor of a smartphone;
The unusual design and color palette;
Support nanoSD memory card, which reach a reading speed of 90 MB/s.
The camera is “dazzled” when shooting in night mode;
System shell needs improvement in the smoothness of action;
Front camera does not justify its 24 megapixel;
Format nanoSD memory card is proprietary, difficult and expensive.
