Now it seems that the top 10 commemorative version of Xiaomi is undoubtedly the highest mobile phone of this year. So, what is the actual performance of this “supreme version” mobile phone? < / P > < p > the top commemorative version of Xiaomi 10 is a big mobile phone in all aspects. In fact, it’s similar to Samsung’s recently released Galaxy note 20 ultra, so the top commemorative version of Xiaomi 10 looks very bulky. The overall size of the phone is 162.4 x 76.1 x 9.5 mm, and it weighs 221.8 G. If it is used with small hands, it may be very uncomfortable. < / P > < p > the front of the mobile phone is a display screen with almost no border, a hole for installing the front lens is reserved at the top left, and a loudspeaker is installed at the top of the display screen. The top edge of the phone is equipped with an infrared transmitter and two microphones. At the bottom there is a usb-c interface, microphone, speaker and dual sim card holder. < / P > < p > Xiaomi 10 supreme commemorative version also adopts the popular on-screen fingerprint recognition, which we have seen a lot. The recognition rate and accuracy can not be compared with the traditional capacitance recognition, but the recognition performance of this mobile phone is also fast and accurate. < / P > < p > due to the slight arc on the back of the mobile phone and the curved screen design, the hand feel of this mobile phone is very smooth. In fact, the previous Xiaomi 9 also used this design style. In general, the appearance and feel of Xiaomi 10 commemorative mobile phone continue Xiaomi’s consistent style. < / P > < p > of course, these are not all the design details of the supreme commemorative version of Xiaomi 10. The most eye-catching module of the camera is the 4. The first mock exam mobile phone is too high, so when the phone is held, the projecting part will touch the finger. Unless you use a protective case, it will be uncomfortable for the camera to stand up to your hand. < / P > < p > Xiaomi 10 supreme commemorative edition has no waterproof and dustproof IP certification. In horizontal comparison, most mobile phones with the same price have waterproof and dustproof certification, such as apple and Samsung. < / P > < p > the top commemorative version of Xiaomi 10 adopts the design of a large earpiece, and the stereo effect can be achieved with the main speaker at the bottom. Therefore, the sound of this mobile phone is very loud, but the sound effect depth is slightly insufficient. The good thing is that it has a usb-c to 3.5mm adapter as standard, and it has a very good Bluetooth codec. < / P > < p > to sum up, the design of the supreme commemorative version of Xiaomi 10 is the same as other mobile phones at the same price. Although there is no obvious place to be brilliant, it is at least matched with the price. < / P > < p > the display effect of Xiaomi 10 supreme commemorative edition is very dynamic, and the screen refresh rate reaches 120Hz. But its effect is not as good as that of phones like oneplus 8 pro and Samsung Galaxy note 20 at the same price. Their effect is more gorgeous. However, other mobile phones do not have the powerful charging function of Xiaomi 10 commemorative edition. < / P > < p > the brightness of the mobile phone screen is very good, and it is easy to see the screen in direct sunlight. In my tests, it had a peak brightness of more than 480 nits, higher than the 412 nits of the Samsung Galaxy note 20 Ultra. < / P > < p > however, for the screen, there is an obvious defect, that is the curved edge of the screen. Although we see this kind of screen is very dazzling in the product promotion, it will change the angle of the light and sometimes increase the glare. < / P > < p > Xiaomi 10 supreme commemorative edition does not use the latest Qualcomm snapdragon 865 + processor, but carries a more conventional snapdragon 865 processor. < / P > < p > Xiaomi did not explain why it did not use the latest chips. From the results, the performance of snapdragon 865 chip is fast enough. With 12gb memory and UFS 3.1 memory chip, no matter playing all mobile games or taking photos and recording videos, there will be no jamming. It can be said that this mobile phone can handle any processing task without performance bottleneck. < / P > < p > in terms of capacity alone, the 4500mAh battery capacity of the top commemorative version of Xiaomi 10 is only the average level of the same mobile phone. After all, it’s up to the battery to support five cameras, a high-performance chipset and a huge high refresh rate display. However, the strategy of Xiaomi’s software background end application has been more radical, in order to ensure good battery life. Therefore, Xiaomi 10’s ultimate commemorative version will last for one or two days. If it’s the normal frequency of daily use, it can last about a day and a half. < / P > < p > what really attracts people’s attention is its high-power charging function. In my test, using the standard 120W charger, it took only 21 minutes to charge the mobile phone battery from 0% to 100%. The principle is to divide the 4500mAh battery into two parts, and charge both sides at the same time. < / P > < p > of course, such fast wired and wireless charging speeds come at a price. In charging, the top commemorative version of Xiaomi 10 mobile phone will become very hot. Wired charging mobile phone will be so hot that people don’t want to hold it with their hands. I don’t know if it will affect the battery life. < / P > < p > the phone also offers 10W reverse wireless charging. With this feature, you can use it to charge the iPhone 11. Most mobile phones that support reverse wireless charging can only charge mobile accessories such as wireless earplugs. < / P > < p > there are five cameras in the supreme commemorative version of Xiaomi 10. Four camera modules are integrated in the back of the mobile phone, including 48 megapixel main lens, f / 1.9 aperture and 1 / 3.2 inch sensor, which support OIS optical anti shake. The other is 48 megapixel, 5 times periscope lens, f / 4.1 aperture, 1 / 2 inch sensor, supporting OIS. There is also a 20 megapixel ultra wide angle lens, f / 2.2 aperture, 1 / 2.8 inch sensor. Finally, there is a 12 megapixel zoom lens, f / 2.0 aperture, and 1 / 2.55 inch sensor. < / P > < p > the screen opening in front of the mobile phone is equipped with a self timer lens with parameters of 20 megapixel, f / 2.3 aperture and 1 / 3.4 inch sensor. < / P > < p > the top commemorative version of Xiaomi 10 can capture very dynamic images with a large dynamic range. In a good light environment, the image quality between the four back cameras has little change. The color restoration is very consistent, slightly oversaturated. < / P > < p > the mobile phone lens can capture the white balance very well, so when the weather is clear, the photos show a bright effect. But when it’s dark, the effect is dull. < / P > < p > most of the time, the main lens and telephoto lens of Xiaomi 10 supreme commemorative edition can’t achieve automatic focusing. Sometimes it doesn’t even focus automatically at all, so it needs to focus manually. In zoom shooting without auto focus may affect the effect, click to make the mobile phone shake too much. However, there are also times when you can focus automatically, and the photos you take will be very clear. In my experience, only one third of the time can be focused. < / P > < p > this phone works well in low light conditions. When the ambient light is obviously insufficient, the mobile phone will automatically increase the exposure. If it is not in an extremely low light environment, the photos taken by the mobile phone will not have much noise. < / P > < p > of course, another gimmick of Xiaomi 10 supreme commemorative edition is its 120 times zoom function. But in my understanding, more than 20 times or even more than 10 times zoom is just a marketing gimmick, not much practical value. < / P > < p > the zoom effect is achieved only by enlarging and cutting the image, which loses a lot of image details and makes the final image completely unusable. Moreover, because the camera is difficult to focus, it is necessary to ensure the brightness of the environment and the stability of the lens in order to get a clear picture, which is too difficult. < / P > < p > Xiaomi 10 supreme commemorative edition also has night view mode, but its performance is very poor. When there are many light spots, there are few details. Unlike other mobile phones, which rely on long-term exposure to achieve night scene mode, the shooting time of the supreme commemorative version of Xiaomi 10 is very fast. As a result, the image quality is also very poor. Maybe it’s just a software problem. I don’t know if the subsequent system update will solve it. < / P > < p > the video effect of Xiaomi 10 supreme commemorative edition is only average at most. It supports [email protected] And UHD 60fps video recording, also support 960fps slow motion mode. Due to the dynamic HDR processing, the camera will always adjust the exposure, which is very uncomfortable visually. < / P > < p > such a price level has entered the competition range of high-end flagship mobile phones. For example, the price of nearly 7000 yuan has reached the price range of Huawei P40 pro and Apple iPhone 11 pro. The price of oneplus 8 Pro is even lower. < p > < p > compared with the wireless version and the wireless version, the top 10 has the advantage of fast charging. However, there are still too many deficiencies in the more critical camera processing capability. < / P > < p > it can be said that the supreme commemorative version of Xiaomi 10 is to package various parameters and functions into one device, and the cost of these things is really not low. But users pay more attention to the experience of integrating these things. < / P > < p > although it has excellent display effect and high camera parameters, it is similar to oneplus 8 pro. Compared with Huawei P40 pro, the difference of photo effect is obvious. As far as charging is concerned, Xiaomi has done a good job. What needs to be improved is the problem of charging and heating.
