Your device has an application that lets you see which applications and features use the most battery power.

View the Battery Status

  1. From the Home screen, touch Apps.
  2. Touch Settings.
  3. Scroll to and touch Battery.
  4. The Battery screen displays the percentage of battery power remaining and how long you might expect that power to last. It also shows the processes that have been using the battery power since it was last charged and the percentage used by each.

Reduce Battery Consumption

Your device provides options that help you conserve battery power. By customizing these options and turning off features in the background, you can use the device longer between charges:

  • Turn off the GPS service.
  • Turn off the mobile data connection.
  • Turn off auto-syncing of accounts.
  • Turn off the Smart stay feature.

  • Decrease the brightness of the display, or use automatic brightness.

Best Practices for Battery Charging

The following guidelines can help you charge your battery properly and safely:

  • Verify that you are using the Samsung USB/charging cable and wall charger included with your device, not third-party accessories.
  • Ensure the USB/charging cable is connected securely and is not being blocked by a cover or case.
  • Check whether a battery or charging indicator appears on the device's display when the USB/charging cable is plugged in.
  • Charge using a wall outlet, not a computer, for best results.
  • When the battery is fully charged, disconnect the device from the USB/charging cable.
