Charging the battery

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