18 2A. Phone Basics
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.
ᮣ Plug the flat end of the charger into the phone’s
charger/accessrories jack and the other end into
an electrical outlet.
WARNING
Do not handle a damaged or leaking Li-Ion
battery as you can be burned.
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.
