  • Check out the battery-draining apps – Start by checking which apps drain the battery the most. Go to Settings > Battery & Performance. Once you figure out which apps are at the top of the list, check for updates or uninstall the app, especially if it is unimportant.
  • Restart your S21 5G – If you haven’t restarted your phone for a while, it’s time to do it now. Many apps and processes run in the system’s background, causing the phone's battery to drain faster. Everything that runs unnoticed will be closed when you reboot the phone. In addition, a restart will refresh the memory and the phone will perform much better.
  • Disable the services you don’t use – one of our biggest mistakes is letting various services work even when we don’t need them. There is no need to have mobile data enabled if you’re connected to a Wi-Fi network at home. Or, why keep the Bluetooth on if you don’t need the headphones now? Once you are done with the service, please turn it off. You’ll notice the battery lasts much longer.

  • Set the screen timeout to 15 or 30 seconds – Go to Settings > Always-on display & Lock screen
