Using Your Phone’s Battery and Charger
Sprint-approved or manufacturer-approved batteries and
accessories can be found at Sprint Stores or through your
phone’s manufacturer, or contact your cable provider for
more information.
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 3.6 hours of continuous digital
talk time.
When there are approximately five minutes of talk time left,
the phone sounds an audible alert and then powers down.
WARNING Use only Sprint-approved or manufacturer-approved
batteries and chargers with your phone. The failure to
use a Sprint-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.
Note: Long backlight settings, searching for service, vibrate mode,
browser use, and other variables may affect battery life.
Be sure to watch your phone’s battery level indicator and
charge the battery before it runs out of power.
