Turn Battery Saver On or Off auf Xiaomi
Battery saver on Xiaomi phones limits background activity to stretch the remaining charge. Once enabled, MIUI throttles background processes, restricts data usage for apps you are not actively using, and delays automatic syncing for email and other notifications.
This is why messages sometimes arrive late or downloads pause mid-way. The system decides which processes get resources based on the active battery mode, not on individual app settings.
Turn Battery saver on or off in Settings
Go to Tap on Settings ➔ Tap on Battery & performance ➔ Enable or disable Battery saver. Toggling it here applies the change immediately, no restart needed.
You can also switch Battery saver from the Quick Settings panel or the Quick Launch bar, without opening the full settings menu. This is useful when you need instant full performance for a call or a navigation app.
Leave Battery saver off if you rely on real-time notifications or need consistent app performance. Turn it on when charge is low and you mainly need calls and messaging to keep working.
