One of the new features of MIUI 9 is smart system optimizations to make the device run faster. It comes with Game Booster that should improve the overall performance of games, and here’s how to make it work. We tested it on the Redmi Note 5A, but the feature should be available to most Xiaomi phones running the Global stable MIUI 9 ROM.
The Xiaomi Security app is used for clearing cache and running security checks, but scrolling down you'll see Tools, one of which is “Gaming speed boost”. Memory is cleaned right away, but to allocate power efficiently, you have to add the game you want to play undisturbed.
The Booster has its own Settings panel that comes with some neat features. To enjoy a more fluid game experience, you can turn off all notifications except for incoming calls, turn off the trio of hardware/software buttons and even prevent switching networks, if you are using both SIM cards.
When everything is optimized, games should run faster, but some devices and their chipsets might heat excessively, so proceed with caution.
Dont worry its a totally useless app
