Charging the Battery
Charge your battery as soon as possible so you can begin using your device.
Keeping track of your battery’s charge is important. If your battery level becomes too low,
your device automatically turns off, and you will lose any information you were just working
on. For a quick check of your battery level, glance at the battery charge indicator located in
the upper-right corner of your device’s display 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 device.
2. Plug in the phone charger to an electrical outlet to start charging the battery.
Charging is indicated by an amber light shown on the notification LED of your device. As the
battery is being charged while the power is on, a charging icon ( ) also appears in the
title bar of the Home screen. After the battery has been fully charged, the notification LED
shows a green light, and a full battery icon ( ) appears in the title bar of the Home
screen.
For more information about the notification LED, see “Top and Front Panels” on page 11.
WARNING
• Do not remove the battery while you are charging it using the phone charger or car
adapter.
