Xiaomi Tablet 2 and Hongmi note3 were released together. The new machine uses Intel's Atom x5-Z8500 processor with X86 architecture+2G memory+16G storage, a rear 8 million front 5 million pixel camera, a 6190mAh battery, and a USB Type-C interface. The price is 999 yuan.
Although the 64G version with win10 will not be available until late December, the Android version of Xiaomi Tablet 2 has come to us. Now let's see what improvement it has and whether it is worth buying.
Packaging and accessories
The packaging of Xiaomi Tablet 2 is close to that of Hongmi Note 3. Instead of the kraft paper box started by Xiaomi 1, it uses a more conventional white paper box, with simple parameters of the machine on the back.
The accessories of the machine include the manual warranty, Type-C data cable and charging plug.
USB Type-C data cable
The output of the attached plug is only 5V/2A, which is not enough for the 6190mAh battery.
Appearance and workmanship
The front of Xiaomi Tablet 2 has not changed much. The logo is on the left side of the forehead, and the light sensor and camera are in the middle.
At the bottom are the three diamond keys of Android, and the keys have a weak backlight. Because the key spacing is huge, it is difficult to touch it blindly at ordinary times. Basically, the key light must be turned on all the time.
The millet flat plate 2 uses a metal body, and the texture of the back has been significantly improved, but the surface treatment is not very fine.
There are openings for noise reduction microphone on the right side of the rear camera and in the center of the top of the fuselage.
The bottom is a double speaker with downward opening, which will have a significant impact on the volume when it is flat. There is a compelling sentence below Xiaomi's logo, "Design by xiaomi in Beijing". The fans don't know how they feel (squint).
There is only one 3.5mm headphone connector on the top of the body.
At the bottom are two fixing screws and Type-C interface.
The power and volume buttons are on the right. The buttons are delicate and small, and the buttons are hard enough to feel the middle distance. The arc processing on the side of the fuselage is similar to the iPad mini4/iPhone 6, becoming more rounded.
The improved variable angle processing and lighter weight make the machine feel significantly improved.
Comparison with Xiaomi Tablet 1 and iPad mini3
From left to right are iPad mini3, Xiaomi Tablet 2 and Xiaomi Tablet 1, and the Xiaomi Tablet 1 on the far right is significantly larger.
In terms of the width control of the front frame, the millet flat plate 2 has also been significantly improved.

Thickness comparison between Xiaomi Tablet 2 and iPad mini3
The iPad mini3 weighs about 333g
The weight difference between millet plate 1 and millet plate 2 is 40g. It doesn't sound like much, but the difference is very obvious.
Hands on experience
The 7.9-inch 2048 * 1536 resolution screen is consistent with the iPad mini 2/3/4, and the fineness is not a problem at all, but the brightness and color performance of the naked eye seems to have a certain gap with the iPad mini, but the specific data will be confirmed in the subsequent detailed evaluation.
In addition, although it does not affect the use, there is still an obvious light leak on the top of the engineering machine we got, and we can not confirm whether it is an individual case or a common problem for the time being.
The factory film on the back of the machine shows that the machine is 5V/2A input.
However, the high pass fast charging charger used by the machine can support the 12V/1A high pass fast charging 2.0 specification. For daily use, a quick charger is more reliable.
In terms of system, Xiaomi Tablet 2 is equipped with MIUI 7 system based on Android 5.1.
Lock screen interface, desktop page 1 and page 2
Although the version number is higher, the overall UI and functions of the system are almost identical to those of Xiaomi Tablet 1. The system comes with a complete set of desktop tool plug-ins.
There are not many native apps, and the system is quite pure. Even the security center in mobile MIUI has been simplified. Only the self start management function that must be available in domestic rom has been integrated in the setting interface (in fact, the security center in tablet MIUI has been simplified since MIUI5).
There is a child mode in the system. Click the application that can be opened and set the password to open it. The overall effect is actually an application lock. When opened, the desktop is like an open folder, and only the selected applications will be displayed.
The system as a whole is extremely smooth, and the millet flat panel 1 equipped with MIUI 5 and MIUI 6 is completely rolled in smoothness. This may be due to the poor optimization of the Nvidia Tegra K1 of the first generation Xiaomi tablet, or the MIUI 7 bonus of the second generation.
performance
Xiaomi Tablet 2 has changed from the original NVIDIA Tegra K1 processor (4-core 2.2GHz A15 architecture) to Intel's Atom x5-Z8500 processor, which is a 4-core 2.2GHz CPU of X86 architecture and can run a complete Windows system. But it is said that because of Microsoft's authorization, the Win version will be released one month later.
Intel's Atom x5-Z8500 for Xiaomi Tablet 2 is the mid-range CPU under Atom. It has x7 on it. They are the successor of the Cherry Trail processor. They use 14nm technology, Airmont architecture, 64 bit processors, and integrate Intel's own Gen8 GPU.
Regardless of the difference in CPU architecture on both sides, the x5-Z8500 has no advantage in performance over Tegra K1 after deducting the performance loss of running Android on the X86 architecture from the running score. In terms of GPU, Intel's Gen8 GPU has exceeded everyone's expectations and is very close to Nvidia's old nuclear bomb Tegra K1.
See our Running points library 。 Compared with the previous generation, this achievement has won or lost. The most obvious improvement is the flash memory writing speed, but the overall improvement is not significant. The overall performance is between Snapdragon 801 and Snapdragon 808, and the overall improvement is not significant.

Power consumption curve
Under preliminary experience:
The heating of the machine is well controlled in daily use, and the heat is mainly concentrated in the middle and upper parts. Generally, it is only used to warm hands.
The power consumption speed is normal, which seems to be slightly higher than that of the previous generation.
If equipped with a fast charging plug, the charging speed is also good. You can charge 10% of the electricity in 10 minutes, and the heating control is OK.
The overall smoothness of the machine has improved compared with the previous generation, but the performance improvement is not obvious. The most obvious improvement is the appearance of materials and workmanship, as well as lower prices. For more detailed test contents, please pay attention to the specific evaluation completed later.
