Charge the Battery

Follow these instructions to charge your phone’s battery using either the included AC adapter or via a USB connection on your computer.

Important: Use only the adapter and the USB cable that came with your phone to charge the battery. When the battery power is too low, make sure to use the power adapter to charge, not the USB cable connection with your computer.
