Stop fast phone battery drain

Identify battery-heavy apps and settings on Android or iPhone.

1. Open the phone’s Battery settings and review usage by app over the last 24 hours or several days.
2. Restrict background activity for an unusually heavy app and reduce screen brightness or always-on display use.
3. Update the operating system and important apps, then restart the phone.
4. Check battery health where available. Sudden shutdowns or a very low health reading can indicate a worn battery.

Follow the official instructions for your device or service. Back up important data before changing settings or attempting repairs.
