Charging the Battery
Your phone’s Li-Ion battery is rechargeable and should be
charged as soon as possible so you can begin using your
phone.
Keeping track of your battery’s charge is important. If your
battery level becomes too low, your phone automatically
turns off and you will lose all the information you were just
working on. For a quick check of your phone’s battery level,
glance at the battery charge indicator located in the upper-
right corner of your phone’s display screen. If the battery
charge is getting too low, the battery icon (
) blinks and
the phone sounds a warning tone.
Always use a Sprint-approved desktop charger, travel
charger, or vehicle power adapter to charge your battery.
Using the Travel Charger
To use the travel charger provided with your phone:
ᮣ
Plug the end of the AC adapter into the phone’s power
interface connector and the other end into an electrical
outlet.
Ⅲ A red indicator light on the phone lets you know the
battery is charging.
Ⅲ
A green indicator light on the phone indicates that
the battery is fully charged.
Ⅲ
An onscreen indicator lets you know that the battery
is charged.
It takes about three hours to fully recharge a completely
rundown battery.
Warning! Using the wrong battery charger could cause damage to
your phone and void the warranty.
