Charging the Battery
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.
Always use a Sprint-approved or Samsung-approved
desktop charger, travel charger, or vehicle power
adapter to charge your battery.
Tip It is recommended that you completely charge your
battery first before using your phone. This guarantees
you begin using your phone with a fully charged
battery.
Plug the flat end of the charger into the phone's
charger/accessories jack and the other end into
an electrical outlet.
