Appearance screen
Xiaomi 9 SE continues the design of Xiaomi 9. The three dimensions of the fuselage are 147.5mm x 70.5mm x 7.45mm, and the weight is 155g. The front is equipped with a 5.97-inch "pearl screen". The panel is Samsung AMOLED with a resolution of 2340x1080432ppi. Corning's fifth generation gorilla glass also supports color AOD information screen display.
There are hidden bar speakers, front camera, light distance sensor and LED warning light above, hidden under the black glass panel. The whole front looks like a smaller version of Xiaomi 9. Unfortunately, this generation of Xiaomi 9 has no dual speakers in the whole series.
The design layout of the back is the same as that of Xiaomi9. The top left is three vertical shots, with different order. From top to bottom, there are super wide angle, wide angle main shot and telephoto, and CMOS is also different. The following photo will be explained in detail.
The first camera light ring is still there. There is a plastic binding at the joint between the back cover and the middle frame, and the transition is not as smooth as that of Xiaomi 9.
The round arc metal highlighted middle frame, the key layout also continues the traditional design of Xiaomi. The AI key on the left is removed, the key feel is crisp, and the feedback is moderate. The card slot is designed for dual Nano SIM, and does not support extended TF cards. The top still retains the infrared transmitter, and the bottom is symmetrically designed with USB-C interface.
The overall design of 9 SE is square, not like the four curved surface radian of Xiaomi 9. It has a strong hand feel, moderate weight, and excellent single hand grip.

It is recommended to use the adaptive mode in daily life.
performance
The world's first Snapdragon 712 is an upgraded version of Snapdragon 710. The 10nm process can be seen from its name. Now let's see how much better it is compared with last year's Snapdragon 710, and how much difference it is compared with the flagship Snapdragon 855.
CPU
Snapdragon 712 CPU adopts the design of two large cores and six small cores. The large core is based on the A75 architecture, with the highest frequency of 2.3GHz; The small core is based on the A55 architecture, with a maximum frequency of 1.7GHz. The only difference between the previous generation Snapdragon 710 and the small core is that the frequency of the large core is increased by 0.1GHz.
First of all, the score of Geekbench 4 is about 1900 for single core and 6000 for multi-core. The Snapdragon 712 on Xiaomi 9 SE has made little progress compared with the Snapdragon 710 on Xiaomi 8 SE. The single core performance is not as good as that of the Meizu Note 9 with Snapdragon 675, The RAR and Pi tests are the same. The small victory over Snapdragon 710 is not as good as Snapdragon 675. There is still a big gap in this year's Qualcomm flagship Snapdragon 855.
GPU
The GPU model of Snapdragon 712 and Snapdragon 710 is Adreno 616, but the frequency is 100MHz higher and the highest frequency is 610MHz.
In terms of GPU, it finally saved face. Both GFXBench and 3D Mark scored higher than those of Snapdragon 675 and 660. Compared with the previous generation of Snapdragon 710, it also improved slightly, but there is still a lot of gap from the flagship Snapdragon 855. As an aside, the 675 dragons of the Meizu have fought back and forth with 660 dragons two years ago, interesting！
Memory, flash memory
Xiaomi 9 SE uses dual channel LPDDR4x memory, with a frequency of 1866MHz. Judging from the running score, it belongs to the average level, and there is nothing outstanding. Compared with Xiaomi 8 SE, it has not improved much.
Samsung UFS 2.1 particles, model KM2V7001CM, leads many middle and low-end mobile phones using eMMC flash memory in terms of score. The sequential reading reaches 467MB/s, which is rare at the 2000 price.
Since the Snapdragon 712 only supports single channel UFS flash memory, the speed is still a bit poor compared with the flagship dual channel.
Conclusion: Snapdragon 712 is the product of Qualcomm's toothpaste extrusion. It's better to improve the frequency and sell it after changing the waistcoat. It seems that Qualcomm has obtained the authentic "Toothpaste Classic" from Intel.
photograph
Xiaomi 9 SE is equipped with a three camera combination, which covers the daily common focal sections. From top to bottom, they are:
S5K3L6 13MP, sensor size 1/3.1 ", aperture f/2.4, unit pixel area 1.12 μ m ultra wide angle lens;
IMX586 48MP, sensor size 1/2 ", aperture f/1.75, unit pixel area 0.8 μ m (four in one output 1.6 μ m);
OV8856 8MP, sensor size 1/4 ", aperture f/2.4, unit pixel area 1.12 µ m telephoto lens.
Let's compare Xiaomi 9, Xiaomi 8 SE and Meizu Note9
day
Sample 1
Sample 2
The first impression of the four mobile phones is very close. The main camera of Xiaomi 9 SE and Xiaomi 9 uses the same CMOS, and the photo style is similar. The picture of Xiaomi 8 SE is cold and the contrast of Meizu Note9 is higher.
Sample 3
Sample 3 Enlarged
Here, Xiaomi has the richest sense of hierarchy and the best analytical power, followed by 9 SE and 8 SE.
Sample 4
In the third group of samples, 9 SE is more accurate in restoring green, more tolerant, and better overall appearance than 8 SE. It accurately restored the scene at 4:00 p.m., which is still no different from Xiaomi 9. Here, Meizu Note9's HDR has a small problem, the exposure is too high, the overall picture is white, and more color information is lost.
Sample 4 Enlarged
Zoom in to see the details. Compared with last year's 8 SE, Xiaomi 9 SE has made great progress in its analytical power, which is still no different from Xiaomi 9. Meizu's analytical power is better than Xiaomi's.
Sample 44800W
Sample 44800W amplification
Open the 4800W mode comparison, and the analytical power of Xiaomi 9 SE has indeed improved. It once again exceeds the 4800W interpolation of Meizu Note9, and is even more powerful than its flagship Xiaomi 9. The old problem is still there. The analytical power has been improved, but the picture is mottled and not as clean as the default mode. It is recommended to turn it on again when there is sufficient light.
Sample 5, 2x zoom
Sample 5 Enlarged
Double zoom ring section, Xiaomi 9 SE and Xiaomi 9 both have telephoto cameras. When you zoom in, you can see that 9 SE is slightly inferior to Xiaomi 9 in telephoto resolution, but still higher than Xiaomi 8 SE and Meizu Note9, which focus on digital zoom.
Sample 6, super wide angle
Sample sheet 7, super wide angle
In terms of super wide angle, it is surprising that 9 SE is wider than 9, and the white balance is more accurate. Xiaomi 9's white balance is slightly red, interesting！

Sample 3 Super Night View
In terms of night scene, compared with the previous generation of 8 SEs, it has made significant progress. Dark details and highlight suppression have been improved, which has solved the problem of highlight color overflow of the previous generation, and the analytical power has also been improved to a certain extent.
In conclusion, Xiaomi 9 SE has made great progress compared with the previous generation 8 SE. Its hard power is very close to that of Xiaomi 9. Its white balance, accurate exposure, tolerance and analytical power have also been improved to varying degrees. The price of 2000 yuan is impeccable, but the camera stability needs to be strengthened. When taking samples, the camera may collapse. If you want to turn on the camera again, you can only restart the phone.
Game measurement
NBA 2K19
In the 40 minute game test, the average is 42 FPS, and the average fluctuation is 3.12 FPS. Observe the frame rate graph. Except for the 60 FPS at the beginning of the game load and the intermediate transition load, the rest of the time is basically 40~50 wandering. In terms of CPU scheduling, the big core is very strong. It seems that the limit performance of the processor is not enough, resulting in the low frame rate of the game. 712 is still too young!
Avalanche
Full special effects open the world for 15 minutes, with an average of 44 FPS, and an average fluctuation of 9.17 FPS. The lowest frame rate during the fight can go to the single digit. If you want to play smoothly, it is recommended to reduce the special effects as appropriate, or change to Xiaomi 9?
Finally, look at the temperature performance. The maximum temperature on the front is 43.3 ℃ at the upper left corner of the screen, and the maximum temperature on the back is 41.4 ℃ at the upper right corner of the fuselage.
Charging and endurance
The Xiaomi 9 SE is equipped with a 3070mAh battery, which is slightly backward compared with the previous generation 8 SE.
Love to play computer games 2-hour endurance test
The endurance performance of Xiaomi 9 SE is better than that of the previous generation 8 SE, but now, everyone is improving the battery capacity, and the endurance performance of 9 SE can only be regarded as passing.
In terms of charging, the attached charging head has returned to the ancestral QC3.0. The actual measurement shows that the original charging head is used. It takes a total of 1 hour and 20 minutes from 5% to full charge. The peak power is about 14W. The charging trickle time is too long in the later stage, resulting in a long total time.
The power of the original charger of Xiaomi 9 is unchanged, so the Xiaomi 9 SE does not take the car with charge pump for fast charging, and wireless charging is also not supported.
other
Up to now, Xiaomi 9 SE has not updated the Game Turbo, and the official commitment is to update it in late March. At present, Xiaomi 9 SE only has the game acceleration software that comes with MIUI.
After the game acceleration is enabled, an unknown object will be displayed semi transparently in the upper left corner. Click it to select pop-up chat, browser search guide and so on. Both liver game and chat are correct.
After the Game Turbo is pushed, there will be more functions, such as real-time monitoring of CPU, GPU occupancy and frame rate, as well as touch settings, pause and hang up.
Xiaomi made a big news on WiFi, which castrated WiFi performance
Both 2.4G WiFi and 5G WiFi are in reverse, and the speed is only half of 8 SE. Even under 2.4G network, the speed is less than 100M optical fiber. The transmission speed of the LAN is halved. If you don't use the LAN frequently, the impact will be small.
Although they all use the fifth generation screen fingerprint of Huiding, the unlocking speed is still a little slower than that of Xiaomi9. In addition, there is a small bug that opens the screen. After the fingerprint is unlocked, the screen brightness will soar, which will affect the experience.
summary
advantage:
1. High cost performance, including Snapdragon 712 SoC, UFS2.1 flash memory and Sony IMX586.
2. Outstanding photographic ability. The photo taking ability is very close to that of Xiaomi 9, but the price is much cheaper.
3. Small screen flagship, so it feels good to hold it with one hand.
Disadvantages:
1. WiFi drives reversing. WiFi speed is lower than that of the previous generation.
2. Low battery capacity. It is only 3070mAh, and it basically needs to be recharged twice a day.
3. You can't buy it.
In general, the Xiaomi 9 SE is a mobile phone worth buying. Users who like small screens should not miss it.
