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.
