appearance
The overall screen plan of Xiaomi 9 is to use the water drop overall screen, which was popular at the end of last year. Xiaomi is called the "pearl screen", continuing the double glass design of Xiaomi digital series. The three dimensions of the fuselage are 157.5mm, 74.67mm and 7.61mm, respectively, and the weight is 173g. This weight is very light with more and more half kilogram mobile phones.
The front is made of Corning's sixth generation gorilla glass. There is a long earpiece on the top of the forehead, and the "pearl camera" is directly below. The LED warning light is placed on the right side of the earpiece, which is not equal in width from top to bottom, left to right, and the forehead and chin are wider than the left and right sides. At the bottom is the fifth generation screen fingerprint, and there will be a reminder when the screen is stopped.
The camera arrangement abandoned the 2018 millet ancestral traffic light design. Because the fingerprint under the front screen replaced the rear fingerprint, the back cover has no previous fingerprint holes, and the integrity is higher. The appearance has also been upgraded to a higher level. The glass has been bent around, making the phone more suitable for the palm, and the feel has been improved. This time, the holographic illusion glass design should be praised. The camera is still in the familiar upper left corner. It is upgraded to three cameras, and the fill light is moved below the camera module. This design is really higher than the iPhone.
In terms of cameras, from top to bottom are telephoto, wide-angle main camera and ultra wide-angle camera. The first camera has a circle of bright colors, which can present different effects under different lights. This design should also be highly praised, making the three back shots look more harmonious, and improving the recognition of the phone.
From left to right are microphones USB Type-C、 Speakers. The antenna is designed on both sides of the bottom, and there is a slight color difference between the antenna and the metal frame.
The top is back to the infrared transmitter, and there is also a noise reduction microphone and antenna strip next door.
The thickness of the whole machine is 7.61mm, and the frame is only 3.5mm. The frame is very small, somewhat similar to Samsung's practice. The key setting is the same as MIX 3. An independent AI key is added. The AI key can be used to set a single machine, double click, and long press functions. The keys are a little loose, and the workmanship needs to be improved.

The data of this screen is not much different from that of the previous generation, and the performance is average, which belongs to the normal level of Samsung A screen. However, in the adaptive mode, several colors are floating.
after Love to play computer games The measured maximum brightness is 412nit manually and 563nit automatically under strong light. This performance is enough to cope with all the scenes. Although the color performance is mediocre, it has achieved good results in brightness.
performance
Xiaomi 9 is currently the second mobile phone equipped with Snapdragon 855 chip. The 7nm process adds the concept of super core to the CPU. One super core, three big cores and four small cores form the 1+3+4 mode.
Ultra large core Kryo 485 Gold (based on A76), 2.84GHz 512KB L2 Cahce; The large core architecture is the same as the super core architecture, but the frequency is reduced to 2.42GHz, and each core is 256KB L2 Cache; Small core Kryo 485 Silver (based on A55) 1.8GHz 128KB L2 Cache per core, and eight cores share 2M L3 Cache. The GPU is upgraded to Adreno 640 585 MHz. The memory still uses dual channel LPDDR4x, and the frequency is increased to 2133MHz.
President Lei said at the press conference that Snapdragon 855 is the most roaring chip in the world. Now let's see how powerful it is by running points (compared with Kirin 980, Apple A12 and Snapdragon 845).
CPU
In the Geekbench 4 test, Snapdragon 855 is at the top level of Android whether it is single core or multi-core (not considering the Exynos series, after all, 9820 single core is close to A12), slightly higher than Kirin 980, but inferior to Apple A12.
In the RAR test, the Kirin 980 is anti super Snapdragon 855. This is because the Snapdragon 855 has castrated the cache. The Snapdragon 855 has only 2M L3 shared cache, and the L2 cache of the three large cores has also castrated to 256KB. In contrast, the Kirin 980 has 4M L3 shared cache, and the four A76 large cores have 512KB L2 cache, so the Kirin 980 has the upper hand in the test that requires cache. Pi calculation of Snapdragon 855 and Kirin 980 are not different, both are much faster than Snapdragon 845.
GPU
Qualcomm said that the new Adreno 640 is 20% faster than the previous generation, and the test results show that it is basically achieved. There is no problem to get rid of the Kirin 980, but there is still a big gap between the new Adreno 640 and Apple A12, which is constantly increasing by 50% every year. Adreno is still in the leading position in the Android camp, but the gap is not as big as before.
Memory
The memory frequency of Snapdragon 855 has been raised to 2133MHz, which is the same as that of Kirin 980. All tests of AndEBenchPRO memory have improved. Both single core and multi-core are the best level of Android, but the latency is not as good as that of Kirin 980.
Flash Memory
The flash memory technology of mobile phones has not broken through for a long time. Now all the flagship ships are equipped with USF 2.1 flash memory, and the gap is not big. They are all at the normal level of USF 2.1. If you want a faster reading and writing speed, you still have to wait for Samsung S10's debut USF 3.0. I hope that Xiaomi can also follow up quickly.
In summary, Snapdragon 855 has achieved good results in various tests. It deserves to be the top Android chip, but Qualcomm has slowed down its progress in the GPU, which has always been the leader. Although the 845's extreme performance was lower than A11, its energy consumption ratio finally exceeded A11. But this year, the 855's extreme performance has been greatly widened by A12 in terms of GPU, There is no need to talk about energy consumption ratio.
Through the above tests, it is clear that Lei is not bragging. The Snapdragon 855 is indeed the strongest chip in the world, but in front of the strongest Apple A12 in the universe, it still seems a little powerless. Finally, A12 said: The only thing that can defeat me is iOS 13.
Measured value of collapse 3
The open world lasts for 10 minutes, with an average of 55 fps. The highest temperature on the front is 40.8 °, and the highest temperature on the back is 38.7 °. The performance of the CPU super core is a bit confusing. The load is not large, and the frequency often hovers at 825MHz. The performance of the big core is relatively stable, and it basically keeps running at 2419MHz.
photograph
In the press conference, President Lei also focused on taking pictures of Xiaomi 9. This time, Xiaomi 9 was upgraded to three shots. In addition to the mainstream wide-angle zoom combination, it also added ultra wide-angle. The equivalent focal length of ultra wide-angle is 13.25mm, which is a bit wider than the ultra wide-angle of Mate 20. Mr. Lei said that macro photography can be achieved by using ultra wide angle. The official claimed that 4CM macro photography can be taken, and humiliated an international fruit brand on the spot.
The IMX586 sensor adopted by Xiaomi 9 can output 48 million pixels of original photos, but the 48 million photos opened in the photo taking interface are generated through 12 million pixels of original interpolation; In the professional mode, let's first compare the 48 million differences between different modes:
The 4800W of Xiaomi 9 is unstable. Sometimes interpolation performs well, and sometimes the original output performs well. In addition, the original 4800W looks like a layer of cloth, and the picture looks dirty.
All 48 million pixel samples of Xiaomi9 below are output in professional mode for comparison to see what the difference is (comparison objects: Glory V20, Huawei Mate 20 Pro, Xiaomi8).

The first impression of the four mobile phones is close, and the hair color trend is the same, but the V20 is not very stable, and sometimes the white balance tends to be blue. The tolerance of Xiaomi 9 is slightly better than that of Glory V20, and there is no big gap in analytical power. If you just want to compare, Glory V20 is better than Xiaomi 9; When the 4800W mode is turned on, the analytical power of each company has been significantly improved. The noise can't be held anymore, and the analytical power is basically at a level.
Scenario 4
Scene 4 Enlarge
Xiaomi 9's dark exposure is lower than that of Huawei and Glory, and its analytical power is also poor. To sum up, in the daytime, Xiaomi 9 could not find any problems when taking photos, which was in line with the flagship performance. Compared with Xiaomi 8, the improvement was mainly due to its analytical power and tolerance; Compared with Glory V20, it is more tolerant and stable.

Xiaomi 9 prefers to take care of the dark in night photography. Compared with Xiaomi 8, Xiaomi 9 has made progress. The details are fleshy. The analytical power and highlight suppression are not as good as those of Glory and Huawei. However, the glory will fade in some scenes, which is not stable enough.

After opening the super night scene, the brightness of Xiaomi 9's picture has improved significantly, and the highlight details have also been retained, but it still failed to defeat Huawei and Glory, which also opened the super night scene. The two Huayao brothers' night scene 6 samples can clearly see the details of the roof, and Xiaomi has become a black ball.
To sum up, there is still much room for improvement in the imaging quality of Xiaomi 9 camera. Compared with Xiaomi 8, there must be progress, but there are still shortcomings in the comparison with the glory V20 of the same IMX586. The highlight suppression at night is poor, and the picture quality is also relatively fleshy. Fortunately, there is a super night view mode, which can make up for these shortcomings. I hope Xiaomi can strengthen the software algorithm in the later stage, This CMOS has great polishing potential.

It still looks shocking!
Charging and endurance
The battery capacity of Xiaomi 9 is 3300mAh, which supports 27W high-voltage charge pump fast charging and 20W wireless fast charging. The standard 27W head is equipped, and the wireless charger needs to be purchased.
According to the 2-hour endurance test of Iooki standard, the remaining power is 83%.
In actual measurement, Xiaomi 9 standard charging head was used for charging. The peak power was about 24W. It took one hour and six minutes to fully charge, which was a huge increase compared with the flagship Xiaomi 8 last year.
When using Xiaomi 20W wireless charger (sold on the official website for 99 yuan), it only takes one hour and 32 minutes to fully charge the battery. The wireless is always cool, and the wireless is always cool.
new function
Quick Start
After the fingerprint is unlocked, continue to long press, and a shortcut will pop up. Sliding can wake up the payment code of Xiaoai or Alipay/WeChat.
AOD new style
Many styles are added to the information screen display for you to choose.
Dark Mode
The system adds dark mode, which covers almost all system applications and lacks support for third-party applications.
Game Turbo
The system homepage will add a game acceleration APP (which can be uninstalled). After opening, there will be a section GAME TURBO Animation.
The home page displays CPU, GPU utilization and battery capacity. On the top right is a menu where you can select games and settings. This page can only be operated horizontally, but the next setting menu will be operated vertically. The logic is a bit strange. I hope the official can add the homepage vertical screen function.
Click Advanced Settings to have a touch option, and you can also add a filter to the game screen. Is this the official plug-in of Xiaomi?
In the game, you can slide the GAME TURBO menu from the upper edge of both sides to the inside to display CPU, GPU occupancy and FPS. If you add another temperature display, it will be perfect.
It is also no problem to flirt with your sister while playing games.
summary
Here are some advantages and disadvantages
advantage:
Equipped with Snapdragon 855 SoC At present, it is the second Android machine equipped with Snapdragon 855, which is very competitive before the 855 is widely distributed.
Strong photo taking ability. Although not as good as the Glory V20, the hardware quality is not inferior to other mobile phones.
Standard configuration 27W Wired fast charging, also supports 20W Wireless fast charging. The charging speed is faster than before.
The vibration motor lifts enormously. Although it is not comparable to the X-axis linear ultra large volume motor of the iPhone, it is already a very good vibration experience.
High cost performance. two thousand nine hundred and ninety-nine Starting from the price, you can buy Snapdragon 855, IMX586 plus ultra wide angle three camera, as well as 27W wired fast charge, and support 20W wireless fast charge, etc.
Disadvantages:
There is still much room for improvement in photography.
The top configuration is only 8GB+128GB. For some people like Xiao Bian who like to watch videos offline, this capacity is a little stretched.
I really can't think of other shortcomings. 2999 is too fragrant.
As the annual flagship of Xiaomi, Xiaomi has given us a satisfactory answer. Xiaomi 9 has balanced performance in all aspects, selling 2999 is worth more than the price. We recommend you to buy it, but only if you can!
