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.
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.
§ As a safety precaution, the battery may stop charging to avoid overheating.
§ We recommend you check the temperature of the battery while you're charging.
Also, avoid charging the battery in hot environments.
§ When you're using the Internet and charging the battery, HTC One may become
warmer. This is normal.
§ To conserve energy, unplug the power adapter from the electrical outlet after you
finish charging.
