Charging the battery

Before you turn on and start using HTC One M9, it is recommended that you charge
the battery.
§ If the battery has been discharged for several days, you may need to charge
HTC One M9 for several minutes before powering it on.
§ Use only the adapter and the USB cable that came with HTC One M9 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.
