screen. If the battery charge is critically low, the battery icon ( ) will be shown in the title bar.
Always use a Sprint-approved or HTC-approved desktop charger, travel charger, or vehicle power adapter to
charge your battery.
To charge the battery:
1. Connect the USB connector of the phone charger to the sync connector on your phone.
2. Plug in the phone charger to an electrical outlet to start charging the battery.
Charging is indicated by a charging icon ( ) in the title bar of the Home screen.
After the battery has been fully charged, a full battery icon ( ) appears in the title bar of the Home screen.

• Do not remove the battery from the phone while you are charging it using the phone charger or car
