Turn Off Connectivity When Unused:

  1. Swipe the “Status” bar down on the home screen
  2. Tap the tiles associated with “Bluetooth”, “Wi-Fi”, and “Location” (GPS) to disable these features

  6. Under “Wireless & Networks”, tap “More”
  7. Turn off “Tethering & Mobile Hotspot”

Switch to 2G Connectivity:

NOTE: If you don’t have quick access to a wall socket or battery bank and your phone runs low on battery or you want to conserve battery life, you can temporarily switch to 2G until the next recharge.

  1. Access “Settings”
  2. Under “Wireless & Networks”, tap “More”

Minimize Third Party App Usage:

NOTE: Third party apps can affect battery life even when unused, due to the fact that they can still run regular background processes. As such, by turning off or removing unused third party apps, you might be able to improve battery life in the long run.

  1. Open the “Settings” menu
  2. Tap “Apps” under “Device”
  3. Go to “Downloaded”
  4. Select the desired app and tap “Force Stop” / “Disable” to turn it off

NOTE: By lowering the amount of data being synced by your device, you can improve battery life in the long run.

  1. Tap “Apps” on the home screen
  2. Open “Settings”
