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 Bluetooth feature.

  • Turn off Wi-Fi.

  • Turn off the GPS (Location) service.

  • Turn off the mobile data connection.

  • Turn off auto-syncing of accounts.

  • 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.
