Using Your Phone’s Battery and
Charger
Sprint-approved or Samsung-approved batteries and
accessories can be found at Sprint Stores or through
Samsung; or call 1-866-343-1114 to order. They’re also
available at
www.sprint.com.
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 5.6 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 turns off.
WARNING
Use only Sprint-approved or Samsung-
approved batteries and chargers with your
phone. The failure to use a Sprint-approved or
Samsung-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 reduce
the battery’s talk and standby times.
Tip
Watch your phone’s battery level indicator and
charge the battery before it runs out of power.
