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
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 Charger
To use the desktop charger provided with your phone:
Plug the outlet from the desktop charger in the wall.
Place your phone into the desktop charger, making sure
that it fits securely. If properly connected, you should
see the charging lights.
A red light on the desktop charger indicates that the
battery is charging.
A green light on the desktop charger indicates that
the battery is at least 90 percent charged.
A yellow light on the desktop charger indicates that
there is a problem charging the phone.
It takes about 3 hours to fully recharge a completely rundown
battery.
