Different from the previous generation of orthodox ARM architecture, Xiaomi Tablet 2 uses the Intel Atom X5-Z8500 processor with the X86 architecture and the 14nm process. At first glance, it is found that the parameters of Xiaomi Tablet 2 are not much better than those of Xiaomi Tablet 1, except for the CPU. What is the actual situation?
In terms of specifications, Xiaomi Flat 2 uses an all metal fuselage with a thickness of 6.95mm, CPU： Intel X5-Z8500 (4-core 2.24GHz), 7.9-inch screen, 2048 * 1536 resolution, 2G memory, 16G/64G ROM, rear camera 8 million pixels, front 5 million pixels, battery 6190mAh, using USB Type-C interface, supporting 5V/2A fast charging. Compared with Xiaomi Tablet 1, its most important improvement is to replace an Intel CPU, use USB Type-C interface, increase fast charging, and the resolution and memory remain unchanged, In addition, in order to control the thickness of the fuselage, the battery capacity has also been reduced by about 500mAh. Before the evaluation, we cannot confirm that it can bring a better experience than the previous generation.

Xiaomi Tablet 2 and Xiaomi Tablet 1 also use an 8 million pixel camera, aperture F/2.0, unknown sensor model, and do not support phase focusing. From the perspective of daytime imaging, the white balance and analytical power levels of the two are similar, but the coating algorithm of Xiaomi Tablet 2 is better, but it must be said that after all, it is photography on the tablet, There is still a big gap between its effect and that of mobile phones.
Weak light

Both of them have no optical anti shake, and their performance in night imaging is normal. It is OK not to zoom in. Once zoomed in, it will find that the analytical power is seriously insufficient and there are many noise points. Compared with the first generation of Xiaomi flat plate, Xiaomi flat plate 2 has less noise points for weak light photography.
Quick charge
The official data of the Xiaomi tablet is that it can support fast charging, with the specification of 5V/2A. However, we have reported that the Xiaomi tablet 2 supports Qualcomm 2.0, with the maximum specification of 12V/1A. Later, we learned from the official communication of Xiaomi that the Xiaomi tablet 2 can indeed support Qualcomm 2.0 fast charging, The official reason why Qualcomm 2.0 fast charging may not be related to the fact that the Xiaomi Tablet 2 uses Intel X5-Z8500 CPU
Endurance&fever
In terms of fever, we used to use NBA 2K15 as the standard to test fever, but it may be due to the compatibility problem of Intel X5-Z8500, which led to the flashback of NBA 2K15 into the game, so we changed it to Wild Racing 8 to test fever. After running the wild drag racing 8 for 1 hour, the maximum temperature of the millet flat 2 is 42 ℃, the heat control is OK, within the acceptable range, and there will be no heat in daily use.
In terms of endurance, compared with the iPad mini 3 with a battery of 6471mAh and the iPad mini 4 with a battery of 5124mAh, its endurance performance is closer to the iPad mini 4. After three and a half hours of medium and high intensity endurance testing, 65% of the battery is left. This performance belongs to the upper middle level of the Android tablet.
summary
As an Android tablet, Xiaomi Tablet 2 performs well. Compared with the first generation of Xiaomi Tablet, it has not brought about performance improvement, and it is more optimized and controlled from the aspects of shape and feel. If you already have Xiaomi Tablet 1, we don't recommend you to buy Xiaomi Tablet 2. It won't make you feel great improvement with the first generation. But if you want to buy an Android tablet and can't find a suitable choice, you may consider Xiaomi Tablet 2
