How can I Monitor and Extend Battery Life for my Samsung Galaxy Tab A? (SM-P550, SM-T550, and SM-T350)

  1. From the Home screen, touch Apps > Settings > Battery.
  2. 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.

    Screen display may vary by user usage.

  • Verify that you are using the supplied Samsung USB/charging cable and not third-party accessories.
  • Ensure the USB/charging cable is connected securely and is not being blocked by a cover or case.
  • Make sure a battery or charging indicator appears on the device's display when the USB/charging cable is plugged in.
