Milestone of Breaking the Limit: Evaluation of Xiaomi 10 Extreme Speed Commemorative Edition

Since 20 1 1 the first generation of Xiaomi mobile phone, the price/performance ratio has been tied with Xiaomi, which has become its biggest label. Although similar product descriptions have rarely been seen in recent years, in many people's subconscious, Xiaomi and cost performance have been equated by default, but cost performance is also easy to misunderstand. After all, cheap things will inevitably be considered as the performance of products, which is also the reason why Xiaomi is branded. Although they tried to hit the high-end market, it was obviously not an easy task.

In fact, in order to subvert this image, Xiaomi also tried to make a lot of efforts and invested a lot of money in research and development. This kind of cost-free investment allows us to see the other side of Xiaomi. For example, the ceramic body that was difficult to use before, the bright silver version with extremely low yield introduced in Xiaomi 6 era, and the appearance of Xiaomi MIX Alpha, which surprised the whole industry last year, and the launch of 1 100 million pixel camera sensor, all of these products shocked every user. Finally, by the beginning of 2020, Xiaomi will no longer be entangled in the price tag, and will wholeheartedly build a truly high-end flagship and launch a brand-new digital flagship Xiaomi 10 series. Once sold, it won the praise of many users and successfully entered the high-end market.

After the development and accumulation of 10 years, Xiaomi officially released a flagship masterpiece-Xiaomi 10 speed commemorative edition on the occasion of the anniversary of 10, which combines the classic craftsmanship of Xiaomi for ten years and also introduces a number of black technologies to show users the performance and configuration of a truly high-end flagship.

"Inherit the classic design.

First of all, in terms of appearance, Xiaomi 10 speed commemorative edition combines the most classic technology of Xiaomi in the past ten years, and the design styles of three modern editions inherit the most classic design technology of Xiaomi mobile phone. We saw the bright silver technology of Xiaomi 6 limited edition 100 sets, the transparent back cover version debuted on Xiaomi 8, and the exquisite ceramic technology, all of which appeared in the Xiaomi 10 speed commemorative edition released this time.

This time I got a customized bright silver version. The mirror glass with four curved surfaces on the back adopts the same process as Xiaomi 6 bright silver plate. When electroplating and coloring in a dust-free vacuum environment, a grain of dust will invalidate the whole glass. The whole processing process, including the transfer between the processing workshop and the material workshop, must be carried out in a dust-free environment, which poses no small challenge to production.

The effect of this manufacturing process is more difficult because of the combination of silver electroplating process and secondary glass. In the electroplating process, hundreds of millions of 0. 1mm silver particles are attached and deposited on the inner surface of glass in a vacuum environment. In order to ensure uniform mirror gloss, silver particles must be attached to the glass evenly. However, due to the different incident angles of silver particles on the arc glass arc, the thickness of the film will be different, resulting in water ripples or orange peel, and the slightest defects under the mirror glass will be infinitely magnified. This also makes this process seem almost impossible.

Now, after the iterative upgrade of the process, the mass production problem of bright silver plate has been well solved. Seven layers of coatings with a thickness of about 300nm were repeatedly superimposed on the glass by evaporator, and the ultra-high reflectivity of 92% was achieved. The specular reflection effect is matched with bright silver with high reflectivity, which has a strong visual impact and creates a sense of mystery in the future.

Xiaomi 6 Bright Silver Exploratory Edition almost satisfied the imagination of all users at that time. This design, which looks like a water drop in science fiction, is presented again in Xiaomi 10 Supreme Commemorative Edition, which further brings users a colorful visual experience.

"Screen upgrade 120Hz refresh rate supports MEMC motion compensation.

Xiaomi 10 speed commemorative edition not only inherits the classic craft, but also makes some corresponding upgrades. The 6.67-inch hyperboloid OLED screen of 120Hz has been further improved compared with the 90Hz of Xiaomi 10 series. Due to the higher refresh rate, Xiaomi 10 Extreme Edition can also display more pictures in a unit time, which will be smoother during use, and can effectively reduce the smearing of words and other contents during sliding when Weibo or news client list pages are swiped.

Accordingly, the touch sampling rate of this screen is increased to 240Hz, which can respond to the touch action in the first time, greatly reducing the response delay during the touch process of the mobile phone. The advantages of high refresh rate and high touch sampling rate in game scenes are naturally prominent, which effectively reduces the tearing of high-speed sports scenes and is very suitable for racing games and FPS shooting games.

With the support of high refresh rate screen, Xiaomi 10 Extreme Memory Edition supports MEMC motion compensation technology, and inserts a compensation frame between two frames that is not in the video source itself to achieve the purpose of smoother picture. MEMC technology fundamentally solves the problems of high frame rate and few film sources, and optimizes the viewing experience to the greatest extent through the frame insertion algorithm, bringing smoother viewing effect.

"Native 10-bit screen with 64 times color display.

Xiaomi 10 speed commemorative edition is equipped with native 10bit color depth screen and107 billion color display, which is 64 times of the traditional 8bit screen. 8bit color depth means that each channel of screen R, G and B has 2? That is, there are 256 color levels, and 10bit means that each channel of R, G and B has 1024 color levels. When displaying the same picture, the color of 10bit is richer and more accurate, the picture is more delicate and the color transition is smoother.

Compared with other mobile phone products, the native 10bit screen of Xiaomi10 speed commemorative edition can display10.7 billion colors without FRC technology (8bit+2bit). Through the actual color test, we can also see that at the stage of obvious color transition, there is no obvious loss of the overall color after amplification, and there is no color block problem caused by color loss, and the overall color is excessively natural and smooth.

On this basis, Xiaomi 10 speed commemorative edition screen passed HDR 10+ certification. For the video supporting HDR 10+ specification, dynamic tone mapping can be realized frame by frame, and each frame can be displayed with the most suitable HDR effect. The dark scene is deeper without losing dark details, and the bright scene is bright and transparent. We further demonstrate this rich color expression by recording and playing the signal source of HDR 10+ directly on the screen.

Xiaomi 10 Extreme Commemorative Edition continues the professional color matching of Xiaomi's high-end series of mobile phones. Every screen is precisely calibrated before leaving the factory to ensure that every screen can accurately restore the true color. Xiaomi provides users with ultra-accurate color reproduction through technology accumulation. The original color of Xiaomi 10bit is deep, which makes the color display of Xiaomi 10 Extreme Commemorative Edition richer and the color reproduction more realistic, even meeting the needs of designers in professional fields.

Xiaomi 10 speed commemorative edition is also equipped with front and rear dual light sensors appearing on Xiaomi 10 Pro. Through the AI intelligent judgment of the front and rear light sources of the fuselage, it can automatically adapt and adjust according to the ambient light accurately, greatly improving the accuracy of light sensing and solving a big problem that the automatic brightness of the mobile phone is erratic.

"The first 120 times ultra-telephoto low-light camera was launched, and DXOMARK was the first one.

Next, I will introduce you to another obvious hardware upgrade-camera module. Since the independent camera department was established on 20 18, Xiaomi image has reached the peak of mobile phone photography technology with amazing development speed. It took the lead in using the 1 100 megapixel sensor last year. By the beginning of the year, Xiaomi 10 Pro had achieved the world's double first in cameras and videos. It proves Xiaomi's outstanding strength in image.

Now Xiaomi 10 Extreme Commemorative Edition is another milestone of Xiaomi's professional imaging strategy. With periscope 120 times super telephoto lens; The customized main camera adopts11.32 inch super-large bottom and super-large pixel sensor; 128 super wide-angle lens and classic portrait lens with 50mm focal length. These four cameras cover the photographic needs of various focal lengths and meet the needs of users in different shooting scenes.

In addition to the first hardware upgrade in these industries, hardware dual-native ISO fusion hyperdynamic technology and chip-level single-frame progressive HDR technology have been realized in mobile phone images, bringing the hyperdynamic range level of mobile phones to a new field; Professional 8K movie camera supports dual 8K video recording of main camera and telephoto lens, and has many professional functions, such as log mode, director mode, and simultaneous opening of multiple cameras.

First of all, let's take a look at this 120 times super telephoto lens, which uses the familiar IMX586 image sensor. Since last year, many flagship models have adopted this sensor as the main camera. Because Sony IMX586 can reach 1.6um after the pixels are four in one, it can take night photos with low highlights and dark details in scenes with poor lighting. In addition, the periscope telephoto supports split OIS anti-shake, which avoids the blur problem caused by jitter during shooting and can greatly improve the filming rate; The ultra telephoto lens also supports a telephoto viewfinder. When the zoom is more than 15 times, a small window picture-in-picture preview is added to the screen, and the focus position is displayed in real time, so that the experience of telephoto camera in positioning the subject can be improved more conveniently and quickly.

After zooming at 10 times, you can still see the details of glass and wall clearly.

Xiaomi 10 speed commemorative edition has customized 48 million super-large base and super-large pixel main camera. It adopts the rare super-large base of11.32 inch, with a single pixel size of 1.2μm and a four-in-one super-large pixel of 2.4μm, which has excellent photosensitive performance. In complex shooting environments such as dark light, backlight and high light ratio, the rare 8P lens in the industry supports OIS optical image stabilization and 8K video recording. Both the sensor size and lens specifications have reached the top level, and ordinary users and professional photographers can have an excellent shooting experience.

The sensor of the main camera is not only a big bottom and a big pixel, but also the customized main camera is the first to support hardware dual native ISO fusion super dynamic technology, chip-level single-frame progressive HDR technology and HDR 10 video shooting, which can improve the dynamic range and color gamut of photography and video recording.

Friends who know how to shoot must know that when shooting at night, you need to improve ISO to get enough brightness, but too high ISO value will often bring more picture noise, making the whole picture look unclear, so the concept of dual native ISO has gradually appeared on high-end professional cameras to solve the problem of dim light noise.

When Xiaomi 10 speed commemorative edition took photos of Zhang Daguang, two photos were imaged by dual native ISO, while the low native ISO got a photo with high light but no exposure, and the plateau ISO got a photo with rich details in dark light. The two photos were combined into a super-dynamic photo with larger dynamic range, better tolerance and excellent noise control.

Because the customized sensor is adopted, the hardware on the sensor side supports the dual native ISO fusion super dynamic technology, and when painting from the sensor, you can have the image fused by dual sensitive ISO, so you can not only take super dynamic photos, but also make HDR videos with high dynamic range when shooting videos. Compared with the traditional HDR photos synthesized three times, it can effectively reduce the existence of ghosts when shooting dynamic objects. Xiaomi 10 Extreme Commemorative Edition supports HDR 10 video recording function, and can collect 10bit video materials with 4K or 8K resolution.

Thanks to the dual native ISO fusion technology of the main camera and the CMOS image sensor with color depth of 12bit, Xiaomi 10 speed commemorative edition can record videos with color depth as high as 12bit, which has exceeded the 10 bit specification of HDR 10bit video. At the same time, ISP and encoder support 10 bit data processing. In addition, the screen supports native 10bit display, and Xiaomi 10bit commemorative edition opens the entire 10bit link from acquisition, ISP, codec and display, no matter from shooting to video image processing to display, the whole link covers HDR 10 Xiaomi mobile phone.

"The first batch of mass production 120W wired secondary charging and 50W wireless fast charging.

In terms of charging, Xiaomi 10 speed commemorative edition has been upgraded in an all-round way, adopting a triple fast charging architecture consisting of 120W wired charging, 50W wireless charging and 10W wireless reverse charging.

Xiaomi 10 speed commemorative edition is the world's first smartphone to realize mass production of 120W wired charging. According to official data, 4 1% wired charging can be realized in 5 minutes and 23 minutes 100% wired charging. After our actual use test, the battery can be fully charged within half an hour without turning off the functions such as update and wireless.

Xiaomi 10 Extreme Commemorative Edition has customized two ultra-efficient charge pumps with a conversion rate of up to 98.5% to be used in parallel, converting the large voltage of the charger into two low-voltage charging channels that can be directly received by the battery and directly input into the battery. This reduces the charging voltage, realizes the current shunt in the charging process, and effectively avoids centralized heating.

I believe that users who have used wireless charging know that wireless charging is indispensable for a complete mobile phone charging experience. When it comes to wireless charging of Xiaomi mobile phone, it has always been ahead of the whole industry. From 20 18 to 20 19, Xiaomi 9 Pro was the first to launch 30W wireless charging. Xiaomi has always been ahead of other flagship models in the research and development of wireless charging.

This Xiaomi 10 speed commemorative edition redesigned the high-power wireless fast charging architecture based on Xiaomi 10 Pro, and mass-produced 50W wireless second charging technology for the first time in the world. According to official data, the 4500mAh millet 10 speed commemorative edition can be charged to 100% in 40 minutes by wireless charging. At the same time, Xiaomi's wireless secondary charging technology also supports wireless reverse charging function, and uses reverse direct charging to realize reverse wireless charging output, with the highest power 10 watt.

In addition to mobile phones, there are many accessories released with Xiaomi 10 speed commemorative edition, including 55W vertical air-cooled wireless charging, which not only supports 50w fast charging of Xiaomi 10 speed commemorative edition, but also supports other mobile phones that support wireless charging, such as iPhone. 20w intelligent tracking wireless charger saves the trouble of finding alignment coil when charging. As long as it is placed on the charging board, the coil will automatically track and charge, and multiple mobile phones can be charged in turn, which is quite convenient.

"Configuration and performance

Xiaomi 10 speed commemorative edition is equipped with Snapdragon 865+LPDDR5+UFS 3. 1 flagship configuration. The clock frequency of the latest generation LPDDR5 memory is 2750MHz, which is nearly 30% higher than that of the previous generation LPDDR4x memory, and it is the highest speed memory specification at present. At the same time, compared with LPDDR4x, the working voltage of LPDDR5 is lower, which further reduces the power consumption. Built-in brand-new UFS 3. 1 flash memory, supporting Write Turbo write acceleration and HPB host performance enhancer, can effectively solve the problem of long-term use of mobile phones, and provide strong reading and writing performance with LPDDR5 memory.

In terms of game experience, Xiaomi 10 speed commemorative edition has added a number of innovative gameplay such as Game Turbo 4.0, which can customize GPU driver parameter settings for different games, such as frame rate, resolution, anti-aliasing, anisotropic filtering, texture filtering quality and many other parameters can be customized and adjusted to meet the more extreme game needs of high-end players. In addition, the game trial mode is supported, and the advantage of large memory is fully utilized, so that the game can be directly downloaded and installed in high-speed memory, thereby improving the startup speed of game installation by 40%-60%, and can be deleted at any time after trial play, without occupying storage space and generating fragmented files.
