Charging the Battery
Charge your battery as soon as possible so you can 
begin using your phone.
Keeping track of your battery’s charge is important. If 
your battery level becomes too low, your phone 
automatically turns off, and you will lose any 
information you were just working on. For a quick 
check of your battery level, glance at the battery charge 
indicator located in the upper-right corner of your 
phone’s display screen. If the battery charge is getting 
too low, the battery icon (
) blinks and the phone
sounds a warning tone.
Always use a Sprint-approved or Samsung-approved 
desktop charger, travel charger, or vehicle power 
adapter to charge your battery.
WARNING
Do not handle a damaged or leaking Li-Ion 
battery as you can be burned.
