Xiaomi phone brakes: how to return performance in 10 minutes

Even Xiaomi’s flagship models eventually start to “hang”: apps open for a long time, animations twitch, and the system responds to commands with a delay. 80% of the time the problem lies not in the hardware, but in clogged memory, background software or errors. MIUI. The good news is that 9 out of 10 users can remove the brakes themselves without contacting the service center.

In this article, we provide step-by-step instructions for models from Redmi Note 10 to Xiaomi 14 Ultra, including hidden settings. MIUI, We'll look at software methods like cleaning up cache, turning off animations, and hardware-based methods like battery wear, overheating. Spoiler: 60 percent of the time, a banal reboot in Safe Mode helps -- but more on that later.

If your Xiaomi started to slow down after the update, that’s a separate story. MIUI 14/15 There are some background optimization bugs that even Snapdragon has. 8 Gen 2 work 30% We'll tell you how to roll back the firmware or turn on hidden performance mode.
