How to Enable and Configure Battery Saver Mode on Xiaomi HyperOS
When your Xiaomi battery is running low, Battery Saver mode extends it significantly by restricting background activity, reducing performance, and limiting visual effects. Here's how to use it.
Types of Battery Saving Modes in HyperOS
| Mode | Battery Extension | Restrictions |
|---|---|---|
| Battery Saver | Moderate (~20–30%) | Limits background sync, reduces CPU speed |
| Ultra Battery Saver | High (~50–80%) | Only allows calls, SMS, and 1–2 selected apps |
| Balanced (default) | None | Normal operation |
How to Enable Battery Saver
Method 1 – Quick Settings:
Swipe down to open Control Center → tap the Battery Saver toggle (battery icon with leaf).
Method 2 – Settings:
Go to Settings > Battery > Battery Saver → toggle "Use Battery Saver" to ON.
Configure Auto-Activation
Go to Settings > Battery > Battery Saver > Turn on automatically → set a percentage trigger (e.g., automatically enable at 20 %). This way you never accidentally run out of battery.
How to Enable Ultra Battery Saver
Go to Settings > Battery > Ultra Battery Saver → tap "Turn on". Select which apps are allowed in this mode (you can allow up to 5 apps — recommended: Phone, Messages, Maps, one messaging app).
What Battery Saver Restricts
- Background app syncing (email, social media won't auto-refresh)
- Location services for background apps
- Visual effects and animations reduced
- Screen brightness may be automatically lowered
- CPU performance capped to reduce heat and consumption
When to Use Each Mode
- Battery Saver: daily use when battery drops below 25 %
- Ultra Battery Saver: emergencies when you need the phone to last until you reach a charger
