Charging a Battery
Your phone is powered by a rechargeable, standard Li-Ion
battery. A Wall/USB Charger (Charging Head and USB cable)
is included with the phone, for charging the battery.
The battery comes partially charged. You must fully charge
the battery before using your phone for the first time. A fully
discharged battery requires up to 4 hours of charge time.
After the first charge, you can use the phone while charging.
Warning! Use only Samsung-approved charging devices and
batteries. Samsung accessories are designed to
maximize battery life. Using other accessories may
invalidate your warranty and may cause damage.
Note: Long backlight settings, searching for service, vibrate
mode, web browser use, and other variables may
reduce the battery’s talk and standby times.
Although you can use the phone while the battery is
charging, doing so will require additional charging time.
Using the Travel Charger
Important! Verify that the handset battery is installed prior to
connection. If the battery is not properly installed
and the wall charger is connected, the handset
may power off and on continuously, preventing
proper operation.
1. Plug the flat end of the Travel Charger into the
charging/USB port and the other end into a standard
AC wall outlet.
