Charging the battery
Before you turn on and start using HTC One remix, it is recommended that
you charge the battery.
Use only the adapter and the USB cable that came with
HTC One remix 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.
1. Insert the small end of the USB cable into the USB connector.
2. Insert the other end of the USB cable into the power adapter.
3. Plug in the power adapter to an electrical outlet to start charging
the battery.
