Appearance and ease of use
Huawei Mate 20 is the closest relative of Huawei Mate 20 Pro, but differs from it noticeably. And, admittedly, for the better. The older version is heavily narrowed, almost sharpened sidewall, and here the lateral edges are much wider, there is a hard grasp, because the glass screen is more flat. Huawei Mate 20 Pro with its 3D glass with strongly rounded edges literally slips out of the palm, like a piece of soap, when you try to control one hand. Huawei Mate 20 with the "usual" 2.5 D-Glass is perfectly held in hand, although the backrest they have the same rounding. This proves once again that the best is the enemy of the good, it is never worth to overdo it.
Huawei Mate 20 is also wider than its "slippery" fellow, and wider and the screen, so that read on it more comfortable. In this case, the body is not only not heavier, but even slightly lighter in weight than the more compact, but also a heavier version of Mate 20 Pro. In General, the ergonomics of Huawei Mate 20 in all surpasses Huawei Mate 20 Pro, whose beauty demanded too much sacrifice.
The Materials here are the same: the side frame is made of metal, and both panels are made of glass. Depending on the color, The texture of the back wall changes. The Version with a gradient is perfectly smooth and markaya, but there is still a variant with a backrest covered by small notches for giving effect of roughness. Both options have a blue tint in color.
Another huge advantage of the usual Huawei Mate 20 is a drop-in-the-screen cutout, which, compared to the wide "bangs" Huawei Mate 20 Pro takes up very little space at the display, leaving most of the user. The Information on the display is placed, naturally, much more.
The Sad thing is that the edges of the screen are just as rounded as possible. Users do not like it, users do not enjoy it, but the manufacturer does not care.
The Buttons of Huawei Mate 20 are again nicer: they are larger, and even the texture of the surface are different. The power Button has a grooved surface with a notches, it does not confuse to the touch with the volume rocker, while the Mate 20 Pro both buttons are too small and equally smooth
Another Nice news: The fingerprint scanner here is not a slow screen, as in Mate 20 Pro, and "traditional", with a round own platform, located, however, on the back cover. The Scanner works quickly and clearly.
The Tray for the two Nano-SIM cards is exactly the same as the older model. The microSD memory Card cannot be installed there, but instead of one of the SIM-cards it is possible to insert a memory card of the new format nanoSD, which, however, has not yet been seen on sale.
And trusts This joyful picture of the total superiority of ergonomics Huawei Mate 20 over the more expensive model Huawei Mate 20 Pro (the difference, among other things, is 30 thousand rubles!) the presence of 3.5-millimeter audio output for conventional headphones. Applause, Curtain.
In Fairness, Huawei Mate 20 Pro protection of the hull from water and dust was better: IP68 corresponds to dust and performance under water, and IP53 Huawei Mate 20-is only dust-proof (some dust can get inside, but it is not The device) and protection against splashes and rain.
Huawei Mate 20 is equipped with an IPS display with a diagonal of 6.53 inches and a resolution of 2244 × 1080, covered with 2.5 D-glass Corning Gorilla Glass. The Physical dimensions of the screen are 72 × 150 mm, the aspect ratio is 18,7:9, the point density is 381 ppi. The Frame has a width on the sides on 2 mm, from below-4 mm, on the top-also 4 mm (a small drop-out cut can not be considered at all).
The editor of sections "Monitors" and "Projectors and TV" Alexey Kudryavtsev conducted the Detailed examination with the use of measuring devices. Here is his expert opinion on the screen of the sample.
The Obverse surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are better than the screen of Google Nexus 7 (2013) (hereinafter just Nexus 7). For the sake of clarity, let's give a photo, on which the screens are turned off the white surface (on the left-Nexus 7, on the right-Huawei Mate 20, then they can be distinguished by size):
The Screen at Huawei Mate 20 is noticeably darker (the brightness of the photos 112 against 123 in the Nexus 7). Double reflected objects in the screen Huawei Mate 20 very weak, it shows that between the layers of the screen (more specifically between the outer glass and the surface of the LCD matrix) there is no air gap (screen type OGS-One Glass Solution). Due to the smaller number of borders (such as glass/air) with strongly differing refractive coefficients such screens are better to look in conditions of intensive external illumination, but their repair in case of cracked external glass is much more expensive, Because you have to change the entire screen. On the outer surface of the screen there is a special Oleofobnoe (fat-repellent) coating, which is even better efficiency than the Nexus 7, so the fingerprints are removed significantly easier, and appear at a slower rate than in the case of conventional glass.
At output of a white field on full screen and at manual control of brightness its maximal value made 530, 0, 2 cd/m² under usual conditions, in very bright light it rises up to 830 cd/m². In this case, the larger the white area on the screen, the lighter it is, that is, the actual maximum brightness of the white areas in the output of the real image will be below the specified values. But the stock of brightness is still there, so the readability of the screen in the daytime in the sun should be at a good level. The Minimum brightness value is 2.0 cd/m², i.e. a low level of brightness without problems allows the device to be used even in complete darkness. There is An automatic brightness adjustment According to the light sensor (it is above and to the left of the front camera lens). In automatic mode, the brightness of the screen increases as well as decreases when the ambient light conditions change. The Operation of this function depends on the brightness adjustment position: The user can try to set the desired brightness level in the current conditions. If not to intervene, in total darkness the auto-brightness function decreases brightness up to 6 cd/m² (very low), in the conditions illuminated by artificial light office (approximately 550 lux) installs on 160 cd/m² (normal), in a very bright environment (corresponds Illumination of a clear day outside the room, but without direct sunlight-20000 lux or a little more) increases to 830 cd/m² (expected). The brightness Level of the backlight depends on the position of the slider in the dark and middle conditions, but in a very bright environment is always set maximum. The default Result was not satisfied, so we moved the slider slightly to the right in full darkness and for the three conditions mentioned above, got 10, 240 and 830 CD/m² (the perfect combination). It Turns out that the auto-adjustment function of brightness works adequately and allows the user to customize their work to individual requirements. At any level of brightness the significant modulation of illumination is absent, therefore there is no flicker of a screen.
This smartphone uses A matrix of type IPS. The Screen has good viewing angles without a significant shift of colors, even with large deviations of view from the perpendicular to the screen and without inverting shades. For comparison, we present the photos on which the screens Huawei Mate 20 and Nexus 7 are displayed the same image, while the brightness of the screens initially installed about 200 CD/m², and the color balance on the camera is forced to switch to 6500 K.
Brightness at the angle of the screens decreased (at least 5 times, based on the difference in shutter speed), but Huawei Mate 20 screen is still slightly lighter. The Black field at the diagonal deviation is highlighted in the middle degree (in the Nexus 7 it is still darker) and acquires a purple tint. The Pictures below demonstrate this (the brightness of the white sections in the perpendicular plane of the screens is the same!):
The Contrast (approximately in the center of the screen) is high-about 1300:1. Transition response Time Black-white-black equals 22 MS (10 ms on + 12 ms off). The Transition between gray tones 25% and 75% (by numerical value of color) and back in the amount of 37 Ms. Built on 32 points with an equal spacing of the numerical value of the shade of gray gamma curve did not reveal the shaft either in the lights or in the shadows. The approximating of the power function is 1.98, which is below the standard value of 2.2. At the same time the real gamma-curve deviates markedly from the steppe dependence:
The Presence of dynamic adjustment of the brightness of the backlight in accordance with the nature of the output image we have not revealed that very well.
Spectra component is well separated, which causes a wide color coverage. For the consumer, the wide color coverage is not a merit, but a disadvantage, because in the end the color of images-pictures, photos and movies-oriented to space sRGB (and such an overwhelming majority), have Non-natural saturation. This is Especially noticeable on recognizable shades, such as shades of skin. The Result is shown in the picture above.
However, not everything is so bad: When you select a profile, the Normal [colors] coverage shrinks to the sRGB boundaries.
By default, the balance of shades on the scale is acceptable, because the color temperature is not much higher than the standard 6500 K, and the deviation from the spectrum of the absolutely black body (ΔE) below 10, which for a consumer device is considered an acceptable indicator. In this case, the color temperature and ΔE vary slightly from hue to hue-this has a positive effect on the visual evaluation of the color balance. In This device, you can adjust the color balance by adjusting the hue on the color wheel.
We took advantage of this opportunity. The graphs below present the results obtained after selecting the Normal profile and shifting the points to the specified in the above picture position. The Color temperature has approached the standard value and the ΔE has decreased on average. Some benefit from such correction is, besides brightness has decreased only on 12%. Note that this function is implemented in the variant rather for a tick, as there is no numerical reflection of the correction and there is no field for measuring the color balance. (The darkest areas of the gray scale can not be taken into account, because there is a balance of colors does not matter much, and the error of measurements of color characteristics on low brightness is large.)
There is a function Natural tone, which, if it is included, adjusts the color balance to environmental conditions.
After its activation, we placed the device under LED lights with cold white light, Resulting in 5.0 values for ΔE and 6800 K for color temperature, and under halogen incandescent lamp (warm light)-5.6 and 6100 K respectively, that is, color Temperature has become lower (though insignificant), and the balance has become slightly closer to the spectrum of radiation of the absolutely black body. The Function works as expected. Note that now the standard is to calibrate the display devices to the point of white in 6500 K, but in principle, the correction under the color temperature of the external light can be useful if you want to achieve better match the image on Screen to what is visible on paper (or on any medium on which the colors are formed by reflecting the incident light) in the current conditions.
There is a fashionable setting that allows you to reduce the intensity of blue components.
Marketers have tried to intimidate the user to show the degree of concern of the manufacturer. Of Course, there is no harmful UV radiation (see the spectrum above), and there is no eye fatigue caused by the blue light. In principle, bright light can lead to disruption of the daily (circadian) rhythm (see the article about the iPad Pro with a display of 9.7 inches), but everything is solved by the adjustment of brightness to a comfortable level, and distort the color balance, reducing the contribution of blue, there is absolutely no Sense.
Summarize: The screen has a very high maximum brightness and has excellent anti-reflective properties, so the device without problems can be used outdoors even summer sunny day. In total darkness, the brightness can be lowered to a comfortable level. It is Acceptable to use and the mode with automatic adjustment of brightness, working adequately. Also to the advantages of the screen should be attributed effective oleofobnoe coating, no air gap in the layers of the screen and flicker, high contrast, excellent uniformity of the black field, good stability of the black to the deviation of the view from Perpendicular to the screen plane, color coverage sRGB (when choosing the right profile) and acceptable color balance. There are no Significant shortcomings on the screen, its quality is very high.
The Front camera Huawei Mate 20 received a sensor with a resolution of 24 Mp and a lens with a diaphragm f/2.0. The Camera gives a great detail and sharpness of the pictures. Especially cool are the portraits, made in the mode with the blur of the background, the camera with the support of AI this effect is really good.
The Main camera of Huawei Mate 20 is simpler than that of Mate 20 Pro, but it is also triple. The Main module with sensor resolution 12 Mp and lens with aperture f/1.8 is supplemented with a sensor resolution of 16 Mp with wide angle lens with aperture f/2.2, and the third, 8-megapixel module received telephoto lens with aperture f/2.4. Complements This set of dual LED flash medium brightness, also inscribed in a square of four elements.
On the viewfinder screen with a single button switch modes zoom, and here lies some mystery. 0.6 ×-wide angle (16 Mp, F/2.2, 17 mm), 1 ×-main camera (12 Mp, F/1.8, 27 mm), this is understandable. And the third button-2 ×-gives a picture with a zoom of 2 × (f/2.4, 54 mm), but for some reason 12-megapixel, although the official resolution of the sensor in the third module is 8 Mp. We do not see in the "controversial" pictures of the obvious signs of interpolation, details on them are undoubtedly more than the central part of the 12-megapixel image of the main camera. The Most probable variant that we have planted much better fur, that is a matrix on 12 Mp instead of 8 (and a matrix of high quality) for Telemodul, but have forgotten to correct preliminary specifications.
As in the older model, there is the support of AI, which manages the modes: in the night glued several pictures into one, in Smart HDR expands the dynamic range, and when recognizing the background and object in real time identifies more than 1 500 Scenarios of 25 survey categories. There is a mode of manual settings, as well as special shooting modes-portrait, monochrome, night. It Is possible to save pictures in RAW in manual mode.
Inevitably comparing the results with Huawei Mate 20 Pro, we can state that the main camera is weaker here. And yet, it's still a high level, with enough light the camera copes very well. Telemodul 2 ×, yielding to this parameter of the optical zoom Huawei Mate 20 Pro (that was 3 ×), gives a very decent picture, as well as the telemodul of the older model. We would even say that the picture from Telemodula is preferable to the main one, and would recommend to use it for images (it is clear that in most of the plots such "replacement" can not be performed). The Wide-Angle module is even more cheerful than Huawei Mate 20 Pro, although the drop in detail at the edges of the image is still significant. But the impressive night shots of us from Huawei Mate 20 did not succeed.
Video can be filmed in 4K format at 30 fps and 1080 p at 60 fps. The Video is encoded in H. 265 or H. 264 to choose from. The Quality of shooting in the senior modes is good-both in detail and in sharpness, but at night the camera shoots video noticeably worse than Mate 20 Pro. Sound is recorded cleanly.
Telephone part and Communications
The Smartphone supports a large number of LTE frequencies, but it is not LTE Cat. 21 with a data transfer rate of up to 1.4 Gb/s, as in Mate 20 Pro, and "only" LTE Cat. 13, 400 Mbps. All common LTE FDD bands are Supported (Band 3, 7, 20), as well as the LTE TDD Band 38. In practice, within the urban features of the Moscow region, the device demonstrates a confident work in wireless networks, does not lose touch, quickly restores communication after forced breakage. There are Wi-Fi (2.4 and 5 Ghz, with support for 802.11 ac), Bluetooth version 5.0 (with a bunch of profiles for wireless music broadcast on headphones) and NFC. That's perfect.
The Navigation module works with GPS (dual-frequency, with A-GPS), and with the domestic Glonass, and with the Chinese Beidou, and with the European Galileo. The First satellites even at cold start are detected quickly, during the first seconds, accuracy of positioning does not cause claims. The Magnetic compass required for navigation programs is available in the smartphone.
The Phone application supports Smart Dial, that is, when dialing a phone number immediately carried out and search for the first letters in Contacts. The Ways to sort and display contacts are standard for the Android interface. Vibrate medium power.
The Hardware platform allows the smartphone to keep both SIM-cards in 3G/4G at the same time in active standby mode. Thus, the SIM-card for voice communication will work in a standby mode in 4G, even if to transfer data in 4G the other card is assigned. Work cards in Dual SIM Dual Standby mode, the radio modem is here one.
Software and Multimedia
As a software platform used Google Android last 9th version with its own Shell EMUI 9.0, and this is also the latest version of the interface. It is Promised that "EMUI 9.0 increases overall performance by 12.9% and provides accelerated launch of applications. EMUI 9.0 has received the second generation of GPU Turbo 2.0 technology, which greatly accelerates the processing of graphical tasks using intelligent analysis, providing increased productivity and reducing energy consumption. The NEW algorithm improves touch screen sensitivity and reduces response time by 36%. " We cannot but admire such accuracy of measurements!
Developers have reduced the settings menu items by 10%, combining a number of sections and moving infrequently used items into a separate tab. The Navigation bar is lowered, some visuals are also moved, but in general the user, accustomed to use Huawei smartphones, immediately recognizes the familiar interface.
Paid attention to Security: EMUI 9.0 provides a higher level of data protection with built-in password storage to securely store IDs and credentials for different applications and services. ALL data is encrypted and does not leave the internal memory of the smartphone, allowing you to use the AutoComplete function without the risk of leakage of personal information.
APP Assistant helps you set up notifications so you don't interrupt Your gaming sessions. The Digital Balance control Panel analyzes the activity of personal use of the smartphone and provides statistics on the time of operation with each application, screen unlock frequency and breakdown by periods. Using This data, users can set limits and adjust the time of each application. Wind Down Mode provides a comfortable turndown service, allowing you to adjust the brightness of the display gradually and switch it to monochrome mode with the notification sounds muted for a certain time.
There is a function of unlocking the face, it works fine even in total darkness: At this point the screen itself lights up as brightly as possible, and it seems to be enough to illuminate the face for the camera.
Through wireless headphones with the help of Bluetooth smartphone can play audio as Hi-Res thanks to the support of wireless codec LDAC. Qualcomm aptX HD Support is also available. The Dolby Atmos System allows you to select profiles, but without the possibility of individual adjustments. In general, and in the headphones and through the stereo speakers smartphone sounds worthy: The sound is clean, loud, saturated. Interestingly, the speaker in the lower end is removed from the traditional series of holes, while the older model sound goes right through the hole of the USB Type-C. But There is a 3.5-millimeter audio output, and, like the Mate 20 Pro, the speakers are working in stereo mode.
Huawei Mate 20, as well as the older model, works on a single-chip system Huawei Kirin 980, manufactured on a 7-nanometer process. The SoC configuration includes three CPU clusters: two cores Cortex-A76 with a frequency of 2.6 Ghz, two same cores with a frequency of 1.9 Ghz and four Cortex-A55 with a frequency of 1.8 Ghz. GPU Mali-G76 MP10 is responsible For the graphics performance.
The Amount of RAM is 6 GB, the storage capacity is 128 GB (free 107 GB), also there is not officially delivered to Russia version with 4 GB of RAM. MicroSD memory Cards are not supported here, but you can insert a new nanoSD format card instead of one of the SIM cards. It is Supported to connect external devices to USB Type-C port in USB OTG mode.
Huawei Kirin 980 is the first of the presented SoC, which is produced by 7-nanometer technical process. It is Also the first solution with processor cores Cortex-A76, with GPU Mali-G76, with dual-core NPU unit. The Platform is very powerful, it has no obstacles, it confidently copes with any tasks, quickly opens the application, cheerfully scrolling interface. All proven games, including Modern Combat 3, Mortal Kombat X, Injustice 2 and PUBG, confidently go without the slightest snubs on the maximum settings. With such a huge screen to play games-one fun. The smartphone certainly has a significant performance margin for future updates.
When testing in 3DMark for the most productive smartphones now have the option to run the application in Unlimited mode, where the rendering resolution is fixed to 720p and disabled VSync (because of which the speed can rise above 60 fps).
Heating is more in the upper right part of the unit, which apparently corresponds to the location of the SoC chip. According To the Heat chamber, the maximum heating was 37 degrees (at the ambient temperature of 24 degrees), it is not very much.
Play a video
To test "omnivorous" when playing video (including support for various codecs, containers, and accessibility features, such as subtitles), we used the most common formats that make up the bulk of the existing In the content Network. Note that for mobile devices, it is important to have support for hardware decoding of videos at chip level, because it is often impossible to process modern variants at the expense of processor cores. Also, it is not necessary to wait for the mobile device decoding everything, because the leadership of flexibility belongs to the PC, and no one is going to challenge it. All results are summarized in the table.
This device supports DisplayPort Alt Mode for USB Type-C — output of an image and sound to an external device when connected to a USB port. Work in this mode, we tried together with three adapters (USB Type-C → HDMI company Choetech, Tronsmart CTHA1 and Aten UH3234). When connected to our monitor, the video output is in 1080p mode at 75 Hz of the HR frequency. Two Modes of operation: The output of the alternative desktop (PC mode) or simple copying the screen of the smartphone (projection mode).
In the second case in portrait orientation of a smartphone screen the picture on the Full HD Monitor is displayed inscribed in height and with wide black margins on the sides, and at landscape-inscribed on width with narrow black fields from above and below. There is no point to point in both options. In The alternative desktop mode, the monitor displays a completely different main screen, and the smartphone screen can be used as a touch pad for coordinate input.
The control panel at the bottom of the screen is removed when the image is displayed to the full screen (for example, when playing video). The Output is already in the true resolution of 1920 × 1080 and point to point. Simultaneously with the output of the image and sound can be connected by USB to the smartphone mouse and keyboard, USB stick, use the Cartood, etc., turning the smartphone into a basis for the workplace, but for this adapter or monitor (having input USB Type-C) should allow Connect external USB devices (i.e. have a USB hub). In the desktop mode on the external monitor you can work in parallel on the smartphone, that is, two desktops are obtained simultaneously, but the output of video in the mode of hardware decoding is only on one screen, and the same program is not Can work both there and there. Note that in the case of this smartphone and all tested adapters sound output to the monitor by HDMI did not work: at best, some noise was heard. When connected to the TV TCL L43P6US (1080p @ 60 Hz), no sound problems were observed.
To test the output of video files on the screen of the device, we used a set of test files with moving to one division by frame an arrow and a rectangle (see "Method of testing the video playback and display devices. Version 1 (for mobile devices) "). Screenshots with a shutter speed of 1 C helped to determine the character of video frames output with different parameters: resolution (1280 on 720 (720p), 1920 on 1080 (1080p) and 3840 on 2160 (4K) pixels) and frame rate (24, 25, 30, 50 and 60 fps). In The tests, we used the MX Player video player in Hardware mode. The test Results are summarized in the table:
Note: If There are green estimates in both the Uniformity and Gaps columns, it means that it is likely that when you view the movie artifacts caused by uneven striping and frame skipping, or you will not see at all, or their number and Visibility will not affect the viewing comfort. Red marks indicate possible problems associated with the playback of the relevant files.
By The criterion of the output of frames the quality of video playback on the screen of the smartphone is good, because in most cases frames (or groups of frames) can (but not required) be displayed with more or less evenly alternating intervals and without gaps Frames. However, the ideal smoothness in the case of files with 60 fps is not, because the refresh rate of the screen is approximately 62 Hz, so at least two frames per second output with increased duration. When playing video files with 1920 resolution on 1080 pixels (1080p), the image of the actual video file is displayed in one-in-one by pixels, exactly on the screen height (at landscape orientation) and in the conditionally true resolution of Full HD. However, the features a matrix with white subpixels instead of half blue: The vertical world is displayed through a pixel in a grid. This is true only for the test world, there are no artifacts on the real frames. The brightness range Displayed on the screen corresponds to the standard range 16 – 235: Shadows and lights display all gradations of shades, which is required for the correct playback of typical video files. Note that this smartphone has support for hardware decoding of files H. 265 with a color depth of 10 bits per color, with the output of gradients on the screen is done with a bit better quality than in the case of 8-bit files (However, this is not a proof True 10-bit output). The display of HDR files is also supported.
Battery life Time
Huawei Mate 20 has a built-in battery of a little less than the Pro-version: 4000 Ma · h. But the smartphone works longer — at least, the lower resolution of the screen is affected. In any case, the smartphone shows very high levels of autonomy, with this the hero of the review is all well. In real life, the smartphone confidently survives to evening charging.
Testing has traditionally been conducted at the usual level of power consumption without the use of power saving features, although there are such in the device.
Continuous reading in the program FBReader (with a standard, light theme) with a minimum comfort level of brightness (brightness was exhibited on 100 CD/m²) lasted until the full discharge of the battery 22 hours, and the continuous viewing video in high quality ( 720 p) With the same brightness level through the home Wi-Fi Network, the device operates up to 16 hours. In the mode of 3D-games smartphone can work up to 4 hours depending on the particular game.
The Smartphone supports fast charging SuperCharge, which allows you to fully charge the device in just 1 hour 30 minutes. Unfortunately, this is only possible with the use of the regular cable and charger Huawei SuperCharge. Starts charging the current 3.6 And at a voltage of 9 V, then these values, of course, fall. During the first half hour the battery is filled up to 65%, and the rest gets for the remaining hour.
The Buyer will be pleasantly surprised to learn that Huawei Mate 20 company offers for 47 770 rubles-that is, as much as 30 thousand cheaper Mate 20 Pro. For the difference in the cost of the two versions of Mate 20 you can, for example, buy another good smartphone, the same Xiaomi Mi 8. The hero of today's review is not worse in terms of hardware performance, because it works on the same top SoC Kirin 980. And in many other aspects (unsuccessful ergonomics, slow and buggy fingerprint scanner, lack of audio output 3.5 mm, huge "bangs") ordinary Mate 20 was even better than his older brother. Of course, more advanced cameras, screen and communication capabilities, higher security corps, but 30 thousand rubles?
The Buyer Huawei Mate 20 will delight a perfectly holding ergonomic case, a wide readable screen, a minimal drop-down in the display, the ability to insert your favorite wired headphones and enjoy a longer time Battery life without recharging. Given The huge price difference, Huawei Mate 20 is seen as much more balanced and, as a result, a reasoned acquisition than the flagship Mate 20 Pro.
