without your intervention. You can also initiate a search for service by
pressing any key (when your phone is turned On).

The Power Save feature helps to conserve your battery power when
you are in an area where there is no signal.

screen.
Your screen remains blank while your phone is off (unless the battery
is charging).

Using Your Phone's Battery and Charger

Battery Capacity
Your phone is equipped with a Lithium Ion (LiIon) battery. It allows
you to recharge your battery before it is fully drained. The battery
provides approximately 3 hours of continuous digital talk time or
approximately 8 days of continuous digital standby 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,
playing games, or browser use affect the battery's talk and standby
times.
