If the battery on Android runs out quickly, the phone may turn off in a few hours, even with light use. The main reasons are background apps, screen brightness, or an old battery.
Below are quick solutions.
Method 1: Check battery consumption
- Open Settings → Battery → Battery Usage
- See which apps consume the most energy.
- Limit the background activity of problematic apps or delete them
Method 2: Adjust brightness and screen
- Turn on Automatic brightness
- Set the screen timeout to the minimum comfortable level.
- Disable animations and effects if the device supports power saving.
Method 3: Power Saving mode
- Open Settings → Battery → Power Saving Mode
- Turn on the low battery mode
- Set up automatic activation when a certain percentage is reached.
Method 4: Updating the system and applications
- Update Android to the latest version
- Update all apps via Google Play
Errors in older versions may cause increased battery consumption.
Additional reasons
- Old or worn-out battery
- Constant GPS, Bluetooth or Wi-Fi
- Problems with the firmware
- Using heavy games or videos
Bottom line
Optimizing applications, brightness, and enabling power saving most often helps. If the battery runs out fast anyway, battery degradation is likely.
