Check Battery Usage
Open Settings > Battery to review battery usage by app and see activity over time. Look for apps with unusually high background activity.
Adjust Screen Brightness
A very bright display can use more power. Use automatic brightness when suitable or lower the brightness manually.
Review Background Activity
Check Background App Refresh and decide which apps really need to update when you are not using them.
Use Low Power Mode
Turn on Low Power Mode from Settings > Battery or Control Center when you need to extend battery life. Some background activities and visual effects may be reduced.
Understand Optimized Battery Charging
Review Battery Health and Charging settings. Optimized Battery Charging can help reduce battery aging by adjusting charging behavior based on your routine.
