Using Your Phone’s Battery and Charger
Battery Capacity
Your Sprint PCS Phone is equipped with a Lithium Ion (LiIon)
battery. The standard battery provides up to 3.0 hours of continuous
digital talk time in CDMA mode and up to 3.5 hours of continuous
digital talk time in GSM mode.
The extended battery provides up to 4.7 hours of continuous digital
talk time in CDMA mode and up to 5.2 hours of continuous digital
talk time in GSM mode.
When the battery reaches 5% of its capacity, the battery icon blinks.
When there are approximately two minutes of talk time left, the
phone sounds an audible alert and then powers down.
Note: Long backlight settings, searching for service, vibrate mode, and
browser use affect the battery’s talk and standby times.
Tip: Be sure to watch your phone’s battery level indicator and charge the
battery before it runs out of power.
Installing the Battery
To install the Li-Ion battery:
1. Insert the battery into the opening on the back of the phone at
an angle, making sure the plastic tab on the bottom of the
battery is inserted into the matching slot in the phone.
2. Press down until the battery snaps into place.
