Huawei mate XS is not the most powerful and advanced mobile phone, but it is also the most expensive one in the world – even in folding phones. The letter “s” in the title indicates an upgrade to the original model. < / P > < p > different body materials, new screens, improved hinge mechanisms – what else can prove the high cost of its unusual “smartphone tablet” with flexible screens? < / P > < p > the fact that mobile phones can be expanded into small square tablets is not surprising. However, you don’t want the screen of Huawei mate XS to fold outward instead of inward. When folding, the phone is almost completely surrounded by the screen covering the flexible matrix. < / P > < p > this decision is quite strange, especially considering that the flexible screen is not as strong as the ordinary mobile phone screen glass. This may be due to the fact that although the matrix is flexible, it must still have at least a certain bending radius, but it cannot be folded along the line as simply as paper. < / P > < p > you can see with your eyes and feel with your fingers that there are actually some protruding places in the middle. The screen itself has no protective glass, and the film folds under your fingers. < / P > < p > the screen is covered with a certain film, which has an oil repellent coating, and the fingers slide on it lightly, so it is easy to be covered by scratches. However, the coating is softer than glass. By the way, the strength of the zirconium alloy in the case is also higher than that of the titanium alloy used in the first model. < / P > < p > the metal part of the shell accidentally folds inward and does not remain at the top, which is only displayed when the digital board is opened. The metal is completely matte, but the rest of the bulge is covered with glass. < / P > < p > it contains all the lenses, flash lights and buttons to open the folding mechanism, as well as the company logo. By the way, a button is just a button to release the screen. < / P > < p > Huawei mate XS has only one camera, unlike ordinary mobile phones. Because of the foldable design, the main screen of the mobile phone is always in the same position, and there is no common form of self timer. But your smartphone will fold up, and then the camera will be able to be turned in its own direction. However, if the smartphone is expanded into a tablet, it will not have a front facing camera. Well, on the other hand, there’s no camera on the screen at last – no “drops”, no “bangs”, no “holes”. < / P > < p > Huawei claims that compared with the first version of the model, the deployment mechanism has been improved and enhanced. The right side has a volume button and a power button with a fingerprint scanner on it. At the bottom, there is a USB type-C connector and a main speaker. This is mono. < / P > < p > since there is no front camera, there is no face unlocking function. But capacitive fingerprint scanners make up for that perfectly. The slot can hold two nano SIM cards. Huawei’s mate XS smart phones only offer one color, and the case is not waterproof. < / P > < p > the mobile phone is equipped with AMOLED display with 8-inch diagonal and 2480 × 2200 resolution. The physical size of the screen is 136 × 153 mm, the aspect ratio is 9:8, and the dot density is 414 PPI. The width of the border around the screen is 5mm at the side, 4mm at the top and 5mm at the bottom. The border is wide. The screen does not support refresh rates higher than 60 Hz. < / P > < p > the front surface of the folding screen is made of plastic. In addition, the protective film is glued to most of its surface, which is obviously a part of the screen structure. However, the protective film is not very strong because it is easy to scratch and leave scratches; the surface of the flexible screen is smooth but not flat. However, this actually has no effect on the image. < / P > < p > the screen of Huawei mate XS is a little brighter with 112 brightness and no obvious shadow. The multiplication of reflected objects in Huawei mate XS screen is very weak, which indicates that there is no gap between the layers of the screen. The outer surface of Huawei mate XS screen is obviously oil repellent, so it is easier to remove fingerprints than ordinary glass, and the display speed is slower. < / P > < p > This screen uses the AMOLED matrix – the active matrix on the OLED. Use red, green and blue pixels to create a full-color image, but the red and blue pixels are only half, which can be called rgbg. < / P > < p > in the clip above, you can see four green pixels, two red and two blue, and the manufacturer considers the screen resolution of the green sub-pixel, while the screen resolution of the other two pixels is twice as low. The < / P > < p > screen has an excellent perspective. Indeed, white alternates between almost invisible blue-green or pink hues, even if the deviation occurs at a small angle. But black remains black at any angle. The color restoration is good, the color is moderately saturated, and the color balance of the screen changes. < / P > < p > to summarize. The screen has high enough maximum brightness and good anti reflection characteristics, so the mobile phone screen can display content well even in sunny summer. In the case of complete darkness, the brightness can be reduced to a comfortable value. The mode with automatic brightness adjustment is allowed. The advantages of < / P > < p > screen include effective oil repellent coating, close to sRGB color gamut and good color balance. At the same time, let’s recall the general advantages of OLED screen: pure black and, from the angle of view, the decrease of image brightness is significantly smaller than that of LCD. The overall quality of the screen is high, except that the maximum brightness may be higher. < / P > < p > Huawei mate XS has a set of classic lenses, wide angle, telescope module and depth of field sensor for portrait mode. It’s simpler than pro and P430. There is neither a separate video capture module, nor a large zoom periscope lens, nor a high aperture optical element. No matter how you unfold or collapse the screen, the lens is the same. < / P > < p > the main camera has a 40 megapixel module and an F / 1.8 aperture lens. There is hybrid autofocus, but no optical stability. By default, the lens is shot at 10 megapixels through 4-pixel intelligent merging. Naturally, you can take photos at full 40 MP resolution. < / P > < p > it turns out that images in 40 megapixel mode are very good. There is no noise in these images. Although the details are not the largest, 40 MP images are obviously better than 10 MP images in terms of the number of details. < / P > < p > if the lens is limited to 10MP pixel mode, the overall image quality can be characterized as very high, with very good details and clarity in the center of the frame, and of course there is no color noise. The sensor resolution of < / P > < p > UWA module is 16mp pixels with F / 2.2 lens. The module is also equipped with an autofocus system. < / P > < p > unfortunately, wide-angle modules are traditionally weak. Even in the center of the frame, the details are much lower than the main details, and the edges of the picture are not good. < / P > < p > the telephoto lens with F / 2.4 aperture is equipped with an 8 megapixel sensor, which realizes three times optical zoom and five times hybrid zoom. The module already has a light stabilizer, which is worth praising. Maximum digital zoom up to 30x. Zoom images are always 10 MP pixels, as if they were taken with the main lens. < / P > < p > remote module is very common, it produces very good image quality, so that you can see the details in the distance. There is no special module for macro photography, but shooting with shallow depth of field is not difficult. You can use the main camera and wide angle module at the same time. < / P > < p > the remote module equipped with optical stabilizer can better withstand long night exposure without blurring. At the same time, its moderate sensor can not provide ideal image with high sensitivity. In the night mode, however, the details are more detailed than in the light mode. < / P > < p > Huawei mate XS has no selfie lens, but after folding the smartphone, it can be realized in the main lens. There is no doubt about its quality: excellent picture, high definition, high detail. Even at night, it’s pretty good to take a picture of yourself. < / P > < p > at the same time, the mobile phone supports shooting 3840 × 2160 videos with a maximum resolution of 60 FPS. The video is of high quality in terms of detail, clarity and color, and can hardly be picked out. < / P > < p > the chips in this mobile phone are the best of Huawei chips. In terms of performance, it is indeed a high-end product. It may not be as good as high-end products like Qualcomm and Samsung. In practice, the mobile phone can complete any task without any problem. < / P > < p > Huawei mate XS mobile phone has built-in battery, increasing its capacity by 4500 MAH. However, the powerful chip and huge screen obviously consume so much power that the power of this mobile phone is not so good. However, it can almost meet your daily use time. < / P > < p > this phone can last 17 hours in normal use until the battery is completely dead. If you watch video, this phone can last up to 12 hours. < / P > < p > supports fast charging, and the phone can be fully charged in one hour. In half an hour, the battery power can be increased by 80%. < / P > < p > on the whole, this mobile phone is very good, but the screen is too easy to leave scratches, especially for people like me, it’s hard to see, but curious friends can buy it and experience it. < / P > < p > usually, as always, the phone is conceptual and “not for everyone.”. This mobile phone will still be a milestone in the development of folding screen mobile phones. As time goes on, there will be more and more folding screen mobile phones.
