Here are some tips that can help maximize battery life on your Samsung Galaxy A51.

1. Look for apps using too much battery

The first thing you should do when you notice battery draining fast is check for apps that are using too much battery. Once you have figured the apps causing the battery drain, turn on optimize battery usage to restrict their background activity. Here’s how to do that.

  • Open Settings
  • Tap on Apps
  • Click the 3 dots vertical icon on the top right corner of the screen and select Special access
  • Tap on Optimize battery usage
  • Tap the drop-down arrow to select All. This will show a list of all installed apps on the device
  • Toggle the slider to the right for all apps you want to optimize

2. Put unused apps to sleep

If there are apps that are sitting idle and not being used at all, put them to sleep. This will save a ton of battery life by limiting their background activity. Here’s how to put unused apps to sleep.

  • Open Settings
  • Tap on Device care
  • Tap on Battery
  • Tap on App power management
  • Toggle the option Put unused apps to sleep to ON
  • Then set the Sleep delay for how long to wait before unused apps are put to sleep
  • Select and set to 1 day3 days or 7 days

3. Turn on power saving mode

This is a very useful feature that can significantly improve battery life of your phone. Enabling this feature can however limit your device of some functionality. Here’s how to enable power saving mode.

  • Tap on Device care
  • Tap on Battery
  • Tap on Power mode
  • Select and set Medium power saving or Maximum power saving.
  • You can also enable Adaptive power saving to allow your device to automatically set power mode based on your usage patterns.

Medium power saving mode will turn off Always-on Display and reduce the brightness level by up to 10%. It will also disable background data sync, location checks and limit CPU speed to 70%. While Maximum power saving mode will activate the Dark mode and limit the number of usable apps in addition to restrictions applied by the medium power saving mode.

4. Reduce screen timeout

Long screen timeout can substantially reduce battery life by keeping the screen on when idle. Here’s how to change the screen timeout.

  • Open Settings
  • Tap on Display
  • Scroll down and tap on Screen timeout
  • Select and set the screen timeout.

5. Reduce screen resolution

If your phone is set to maximum resolution, it will quickly drain the battery as higher resolution requires more power. Here’s how to reduce the screen resolution.

  • Open Settings
  • Tap on Display
  • Tap on Screen resolution
  • Select and set the lower resolution

6. Disable features you don’t need

If there are features you don’t use much, turn them off. Features like Edge panels, Edge lighting, Motion gestures, Video enhancer, Smart stay, Smart alert, Easy mute, Palm swipe to capture, etc are rarely used by most users but they are enabled by default. Here’s how to turn these features off.

We recommend turning off GPS and use just WiFi and mobile networks for location tracking if you are running out of battery. Here’s how to do that.

  • Open Settings
  • Tap on Location
  • Tap on Locating method
  • Select and set Battery Saving as the locating method. This will turn off GPS and use WiFi and mobile networks for estimating your location.

9. Don’t use mobile data when cell signal is poor

If you are in an area with poor signal reception, turn off mobile data if you don’t need it as your device uses more power when mobile signal is low as it tries to communicate with your network operator.

10. Disable Wi-Fi, Bluetooth and GPS when not in use

Turn off WiFi, GPS, NFC, and Bluetooth when you are not using them as they keep checking for signal which can drain power. To turn them off, swipe down the quick settings panel and tap the corresponding icon to disable it.
