Save battery using Device maintenance

Samsung has given an inbuilt function to save and optimize the battery power. There are a total of five option in the “Device Maintenance” (Settings -> “Device Maintenance”) and those are:

  • Battery
  • Performance mode
  • Storage
  • Memory and,
  • device security

I am going to cover only first four points under device maintenance but before that you can see “Optimize Now” button. Just click on it and it will automatically optimize the phone. Some of the functions which it performs are:

  • Closing any background apps
  • Freeing up storage space
  • detecting app crashes or any malwares etc.

Battery in Device Maintenance

  • Go to Settings -> “Device Maintenance” -> “Battery”
  • Once you click on battery, you will see three different power saving modes namely
    • Off
    • Mid and,
    • Max
  • Choose the one that you want to use. I prefer mid because “Max” battery mode almost makes your mobile like a basic phone.
  • Below these power saving options, you will also see “Save Power” option. Clicking on it will put the running apps into sleep.
