Using Your Phone’s Battery and Charger
Battery Capacity
Your Sprint PCS Phone is equipped with a Lithium Ion
(Li-Ion) battery. The standard battery provides up to 3.3 hours
of continuous digital talk time and the extended battery
provides up to 5 hours of continuous digital talk time.
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
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.
