The performance of Xiaomi Mobile 3 is basically satisfactory. In terms of appearance, Xiaomi Mobile 3 has been qualitatively improved compared to previous generations of products. The appearance design after the combination of K900 Lumia 920 is quite stunning. This is an unexpected aspect; and although the screen size reaches 5 inches, there is no problem with one-handed control. A lot of effort should have been put into the ergonomic design. In addition, the workmanship of Xiaomi Mi Phone 3 is basically satisfactory, and there are no gaps in the joint part of the panel. Of course, Xiaomi Mi Phone 3 also has certain deficiencies in its casing. Judging from the situation of the engineering machine, there are already more than one scratches on the fuselage. I hope that the future official version can solve the problem of being easily scratched. In addition, the integrated body also eliminates the idea of ??opening the back cover to replace the battery, and also increases the difficulty of maintenance, which is difficult for users to accept. But relatively speaking, there are gains and losses. If you want an excellent appearance design, you can only make certain sacrifices in battery replacement. In terms of performance, the performance of the Xiaomi Mi Phone 3 equipped with the Tegra 4 processor we tested this time is acceptable. In the actual test, the performance can be ahead of the products equipped with the Snapdragon 600 and Exynos 5410 processors, but compared with the products equipped with the Snapdragon 800 There is still a certain gap in terms of processor products. After all, the Tegra 4 processor used in Xiaomi Mobile 3 has made certain compromises in performance due to power consumption and is not as powerful as the original Tegra 4. The Tegra 4 version of Xiaomi Mi Phone 3 does not generate obvious heat in daily applications, but it does have a relatively obvious heating phenomenon during the benchmarking process. This is an inevitable consequence of using high-performance processors and is also a common problem in flagship phones.
