Xiaomi MIX is a "concept mobile phone" released by Xiaomi Company. As a completely unexpected product, Xiaomi MIX is undoubtedly the most technologically sensitive product in the history of Xiaomi. Its ultra-high screen share has reached an astonishing 91.3%, almost to the extent of borderless, which is quite amazing. Conscience is that although Xiaomi named the phone as "concept", the price of the phone is not a concept. Now let's see how this Xiaomi MIX named after concept performs.
Unpacking&Appearance
The packaging box of Xiaomi MIX is different from the pure white packaging commonly used by Xiaomi. MIX uses a black packaging box with the words "Designed By MI" stamped with gold.
256GB is printed on the side, which means this is the exclusive version of MIX, and 256GB UFS2.0 built-in storage is used.
The packaging has a special structure and adopts a folding design. The phone body, protective sleeve and accessories are located in different compartments.
After expansion, all the accessories are on the same plane, so you can get the accessories you want. Both the body and accessories are very reliable, and the packaging is very protective.
The QC3.0 fast charging head equipped with 5V, 2A/9V, 2A/12V and 1.5A as standard is more conscientious.
The quality of the included leather case is good. The inner layer uses a velvet inner surface, which can protect the phone very well. The outer leather feels good, which can cover the whole back and the frame. The protection is very good.
Unlike ordinary mobile phones, Xiaomi MIX does not use traditional earphones because its forehead width is very narrow. Instead, it uses a vibration earphone design built into the frame. There is no hole on the body surface, but it conducts sound through vibration (not bone conduction). In our use, it is not very different from ordinary earphones, Both loudness and call clarity are good.
The forehead and the border on both sides are very narrow, only the chin is relatively wide, so it also has a very high screen proportion, reaching an astonishing 91.3%. Due to the super narrow forehead, the front camera is designed at the bottom, located at the lower right corner of the fuselage. The camera opening is very small and hidden.
Its front camera is 5 million pixels, which adopts the third generation 36 level intelligent beauty, and supports up to 1080P video calls. Although the chin is relatively wide, it is still relatively narrow compared with most mobile phones.
The corners of the screen are designed with large rounded corners. It is a 6.4 inch 17:9 screen customized by Xiaomi in Sharp, with a resolution of 2040 × 1080, a pixel density of 362ppi, and a maximum brightness of 500 nits.
Although its pixel density is not high at present, the overall performance of this screen is commendable. The fineness and color performance are good, and the super high screen proportion gives people a strong visual impact. The system has a built-in eye protection mode and color temperature adjustment, which can be turned on when the light is dark, reducing the output of blue light to protect vision.
The back cover and the frame are made of an integrated ceramic material. The handle is smooth and not very slippery. The holding feeling is more comfortable than that of the ordinary glass back cover. The frame and the back cover are formed as a whole, so the holding part is smooth and does not hurt the hand at all.
The shell of Xiaomi MIX is made of microcrystalline zirconium ceramics with Mohs hardness of 8.5. It was fired at 1500 ℃ for 7 days. Its hardness is second only to sapphire, and it is very wear-resistant and practical. After the author used it naked for a period of time, it still has no scratches. Compared with glass and metal, it is more suitable as the body material.
Because the design of virtual keys is adopted, the front fingerprint identification layout of Xiaomi 5s/Note2 is not used for fingerprint identification. The fingerprint identification is designed below the back camera, and the size of the opening of the fingerprint identification module and the lens is almost the same. However, its position is slightly higher, so you need to adjust your finger fingerprint to touch it.
The power button and volume button are located on the right side of the body, and the most commonly used power button is below the volume button. The location is reasonable.
The SIM card slot is located on the left side of the fuselage, which is tightly connected without any virtual position.
There are 3.5mm headphone jacks and two noise reducing microphones on the top.
At the bottom are speakers, call microphones, and USB Type-C connectors.
The actual appearance of the screen is still quite beautiful, with high color saturation. The color mixing style is slightly different from the general IPS screen, but users can choose the color mode and adjust the color temperature to achieve the most suitable display effect.
The high configuration version uses 6GB of LPDDR4 running memory. After we open multiple APPs, the remaining memory is still about 3GB. There is almost no shortage of memory, and no number of domestic APPs are enough.
Because the Xiaomi MIX has a screen up to 6.4 inches, in order to provide users with a better operating experience, the Xiaomi version of the small dot -- the levitation ball, which can be moved at will, click to display shortcut buttons, which can realize the Home button, multi task, return, screenshot and lock functions. It is more practical, especially when you cannot use your phone with both hands at the same time, The levitation ball is very helpful.
Of course, even with the help of the levitation ball, Xiaomi is still weak in front of the 6.4 inch screen. Therefore, Xiaomi has also added a one handed mode to the MIX. Swipe left or right on the virtual button to activate the one handed mode.
The overall visual impact is very strong, far stronger than that of Sharp's early borderless models. The 6.4 inch large screen has a great experience in viewing pictures, watching videos, and playing games.
What's more, the Xiaomi MIX is a really "usable" model with a strong enough configuration. It uses the 2.35GHz Snapdragon 821 processor+4GB/6GB+128GB/256GB UFS2.0 built-in storage model, which achieves the configuration that a flagship computer should have, and really deserves the word "concept".
Screen quality
Xiaomi MIX adopts a 6.4 inch 17:9 screen customized by Sharp, with a resolution of 2040 × 1080, a pixel density of 362ppi, an official nominal maximum brightness of 500 nits, a contrast of 1300:1, and a color gamut of 94% NTSC. Xiaomi has also built in different display modes in the system, such as eye protection mode, standard mode, etc., and allows users to adjust the color temperature and change the color performance of the screen according to their preferences.
In the standard mode, the color temperature of MIX is about 7100, which is relatively cold. The maximum brightness is about 584 nits, and the contrast is 1816:1. The performance is quite good, especially the brightness, which is basically at the same level as the iPhone. In terms of color gamut, its sRGB color gamut exceeds 100%, and Adobe RGB color gamut is 84.6%. In terms of color accuracy, after we adjust the screen to the standard mode, the DeltaE of the screen is 3.4, up to 7.8. The performance of color restoration is OK, but slightly inferior to Xiaomi Note2, and basically consistent with Xiaomi 5/Xiaomi 5s.
System experience&performance performance
As Xiaomi's boldest attempt ever, Xiaomi MIX has a design different from most of Xiaomi's current mobile phones. For example, it has a large screen up to 6.4 inches. For example, it uses virtual keys instead of the physical keys that Xiaomi has always used. Therefore, the optimization of the MIX system by MIUI is also worthy of attention, but at least in terms of color matching and face value, MIUI does a good job.
The machine adopts MIUI 8.6 operating system, customized based on Android 6.0.1, and most of the colors are consistent with the ordinary MIUI. However, it has to be said that this color match is very good with MIX, and it is small and fresh with a piece of colorful wallpaper.
MIUI Some improvements have been made for MIX, such as the design of the levitation ball function for the 6.4 inch large screen. There is a small switch in the lower left corner of the virtual button to activate it. Similar to the Apple small white dot, it can slide freely on the edge of the two screens. Click to display the shortcut button. Return, home page, multi task, and lock screen can be quickly realized, which is relatively simple and easy to use. Because Xiaomi MIX uses three virtual key designs, Xiaomi has also added settings that can customize key functions, and can exchange the return key/multi task key. Users who are accustomed to the key layout of Google's native system can also quickly get started.
Processor performance
Xiaomi MIX uses the 2.35GHz Snapdragon 821 processor. In terms of processor performance, GeekBench's single core performance is basically at the same level as that of the 8890. However, due to the small number of cores, its multi-core performance is still somewhat lower than that of the 8890 and Kirin 955 SoCs. In terms of RAR and Pi, it has a small advantage over Xiaomi 5 and Xiaomi 5s.
Graphics Performance
In terms of graphics performance, the Snapdragon 821 and the Snapdragon 820 also use the Adreno 530 graphics processor. Therefore, there is no significant difference in graphics performance between the models using the Snapdragon 820 and the models using the Snapdragon 820. Except for the Apple A10, which is the best in graphics performance, the other models are almost the same.
Built in storage read/write performance
In terms of built-in storage, the UFS2.0 used by Xiaomi is quite outstanding in terms of reading and writing performance. The reading performance reaches about 490MB/s, much more than that of Xiaomi for 5s, and the continuous writing reaches 242.76MB/s. The power of 256GB UFS2.0 built-in storage is quite amazing. In terms of random reading performance, Xiaomi MIX also has a quite good improvement. In terms of random reading, it is about 112MB/s, while in terms of random writing, it is about 18.6MB/s. Compared with Xiaomi 5 and Xiaomi 5s, it has certain advantages. The advantages of the large capacity UFS2.0 built-in storage in terms of reading and writing speed are really obvious.
Photo proof
Xiaomi MIX adopts a 16 million pixel rear camera, the sensor model is OV 16880, the size is 1/3.06 inch, the unit pixel size is 1.0 μ m, it supports PDAF phase focusing, the aperture is f/2.0, and it is equipped with a two-color fill light. It is worth mentioning that the premium version of Xiaomi MIX uses 18K gold plating on the camera ring and fingerprint identification of the rear camera, which is slightly better than the ordinary version in visual effect. Next, let's take a look at how Xiaomi MIX performs in camera imaging compared with Xiaomi 5 and Hongmi Note3 all Netcom versions.

In the daytime scene, the white balance preferences of the three Xiaomi models are different, with large color differences. Among them, the white balance of Xiaomi 5 is the closest to the reality. In fact, it is the Red Rice Note3 All Netcom, and the white balance of Xiaomi MIX is the most biased. Both the sky and the glass wall are obviously blue. In terms of picture details, the three are similar. Xiaomi 5 and Xiaomi MIX are relatively close, while Hongmi Note3 All Netcom is slightly inferior.

In this scene, the white balance of the three mobile phones is still different. In contrast, the white balance of Xiaomi 5 is still the most accurate. Xiaomi MIX is a little bit blue, but it is still relatively accurate on the whole. The picture of Hongmi Note3 All Netcom is gray, and the color of the sky and the glass wall is not accurate. In terms of details, the three still cannot open the gap. Among the three, Xiaomi 5 is more tolerant, and the brightness and details of the shade at the lower right are better.

In terms of white balance, Xiaomi MIX is the most accurate. In terms of picture details, Xiaomi MIX is also the best. Xiaomi MIX does a good job in both details and the sharpness of font edges, and the buildings behind the main picture are well preserved. Hongmi Note3 All Netcom sacrificed other details for the brightness of the main part of the picture. The whole picture was overexposed, and the buildings in the background were almost invisible. What is more unexpected is Xiaomi 5. The details are not good. The font performance is fuzzy in many samples, and the exposure is also insufficient.

In the scene that tests the power of discrimination, Xiaomi 5 is the best. The lines of the protective net are relatively clear, but the overall picture is slightly green. Next is Red Rice Note3 All Netcom. Although it is a bit vague, it can still distinguish certain lines. The worst performance is Xiaomi MIX, whose lines have become blurred. In addition to the limited discrimination, the tolerance of Xiaomi MIX also has some shortcomings, and the dark details are ordinary.

In the sunny scene, the white balance of the three players is quite good. Hongmi Note3 All Netcom is slightly red, and Xiaomi MIX and Xiaomi 5 are both relatively accurate. In terms of picture details, the performance of leaf veins is not much different, but in some pictures, Xiaomi MIX is slightly overexposed, so some details are lost, but overall, the three are not much different. In terms of daily performance, the overall performance of Xiaomi MIX is quite good, and its sharpness, detail and tolerance are all fairly good. However, there is still room for improvement in white balance and exposure control.
Night proof sheet

In the night scene, when HDR is turned on by all three, the gap is very wide. Xiaomi 5 is far ahead in terms of picture details, brightness and sharpness. The exposure of Xiaomi MIX is very low, and the overall picture is underexposed, but the noise control is good, and the painting is clean. The sensitivity of the red rice Note3 is also low, so in order to get the same picture brightness, the exposure time is very long, which affects the photographing experience, and the picture is also somewhat blurred.

In the light scene, Xiaomi 5 and Hongmi Note3 all Netcom versions are the same in terms of sensitivity and exposure time. They are very similar in tuning, and their picture brightness and details are not much different. Xiaomi 5 is slightly more tolerant in the dark, and the brick seams on the wall have some reservations, while Hongmi Note3 can only vaguely see some outlines. The performance of Xiaomi MIX in the main part of the picture is fairly good, but the overall exposure is still insufficient, the ISO pressure is very low, and therefore many dark details are lost. The rain covered walls are almost completely indistinguishable. In terms of night view, Xiaomi MIX's performance is really somewhat unsatisfactory, and Xiaomi is a little conservative in the adjustment of this camera.
Endurance&fast charging&heating
In terms of endurance, after three hours of intensive testing, its remaining power is 80%, which can be described as quite violent. Among the flagship models sold on the market at present, there are few models with better endurance than Xiaomi MIX. Such a violent endurance can not be separated from the contribution of the 4400mAh battery, plus the good power control of the Snapdragon 821 and the targeted optimization of Xiaomi, this endurance performance is not surprising. During the test of MIX, the author heard many times that "it is not good hardware to install a system is a good mobile phone", but the author thinks that Xiaomi MIX is not such a mobile phone. Xiaomi has put a lot of effort into MIX, both in the combination of software and hardware, and in the levitation ball and one hand mode designed specifically for MIX, which reflect Xiaomi's attention to MIX, It is not a simple combination of hardware and MIUI.
In terms of fast charging, Xiaomi has its own QC3.0 fast charging head with 5V, 2A/9V, 2A/12V and 1.5A. In our actual measurement, the charging speed has also reached about 15W, which is the normal fast charging speed.
After 30 minutes of NBA 2K test, the front temperature is 42.1 ℃ and the back temperature is 41.3 ℃, which is not bad, and the heating control is also within a reasonable range.
summary
As the true annual flagship of Xiaomi Company, Xiaomi MIX is commendable in terms of appearance design, performance, manufacturing process, system experience and endurance. As a concept mobile phone that does not go far, Xiaomi MIX has done quite well. In addition to its slight weakness in photography, the whole machine is almost impeccable. Although as a concept mobile phone promoted by Xiaomi, Xiaomi MIX will not be widely distributed in the market like 5s and Note 2, in terms of design, technology, experience and endurance of MIX alone, it can be said without exaggeration that Xiaomi MIX is one of the most powerful competitors of the best domestic mobile phones this year.
