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, and 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.
