Battery optimization is one of the first arsenals for MIUI users to save power, referring to the process of adjusting settings to extend battery life on their devices. Turn the power off automatically when the Xiaomi phone is not in use. This feature is available on Android 7 and lower versions also.
Even Android 12, 11, 10, 9, and 8 versions support this. But the interface and settings will be different.
If you sleep at 11 pm, then you can switch it off at that time. Your phone will be ready to switch on again by the time you wake up for a morning walk at 5 am. It saves 6 hours of battery life.

Instead of charging the phone twice in the daytime, it is enough to do it once.
