Charging the Battery
Your Sprint PCS 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(
the phone sounds a warning tone.
Always use a Sprint-approved desktop charger, travel
charger, or vehicle power adapter to charge your battery.
Warning! Using the wrong battery charger could cause damage to
your phone and void the warranty.
Using the Travel Charger

Plug the round end of the AC adapter into the phone's
power interface connector and the other end into an
electrical outlet.
A red indicator light on the phone lets you know the
battery is charging.
An on-screen indicator lets you know that the battery
is charged.
It takes about three hours to fully recharge a completely
rundown battery.
