Battery Capacity

Your phone is equipped with a Lithium Ion (Li-Ion) battery. It
allows you to recharge your battery before it is fully drained.
The battery provides up to 3.8 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.

Installing the Battery

To install the Li-Ion battery:

1.

Insert the battery into the opening on the back of the
phone at a 45-degree angle, making sure to line up the
gold contacts. Gently press down until it snaps into
place.

2.

Install the protective cover by lining up the tabs at a
and gently press up until the cover snaps into place.

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.
