As the Xiaomi launch conference approaches, news about MIUI 9 keeps flowing out. Recently, MIUI official microblog began to release a countdown warm-up poster, and the three posters released were all scientists related to "lightning". Benjamin Franklin invented the lightning rod, Michael Faraday invented the generator, and Nicola Tesla discovered the alternating current. It is easy to see that Xiaomi's official implication this time is that MIUI 9 will bring users a lightning fast experience. At the same time, it has also made great efforts to save power.

In April 2017, Lei Jun required that the new MIUI 9 system should be "smoother, more stable and more power efficient", which coincided with the suggestion of the current MIUI official micro blog. It is known that MIUI 9 will be the first to adapt to Xiaomi 6 and Hongmi Note 4X (Qualcomm). After MIUI 9 is truly stable and smooth, it will be directly copied to a large number of models. MIUI revealed that the second batch of models include Xiaomi 5, Xiaomi MIX, Xiaomi Note 2 and other popular models.

Now, it is less than a day before the launch of MIUI 9's new system. Here is a brief review of the MIUI 9 related information leaked before: MIUI 9 will add three new themes, redesign the lock screen interface, and confirm the addition of split screen function and information assistant function. In addition, MIUI 9 will moderately simplify and optimize some functions that are not just needed, extremely low frequency, and have few users.
