Using Your Phone's Battery and Charger

Warning! Use only Qwest-approved or manufacturer-approved batteries and
chargers with your phone. The failure to use a Qwest-approved or
manufacturer-approved battery and charger may increase the risk
that your phone will overheat, catch fire, or explode, resulting in
serious bodily injury, death, or property damage.
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.
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.
