have a secure seal.
Note: Make sure the battery is properly installed before
switching on the phone.
Charging the Battery
Your phone is powered by a rechargeable Li-ion battery. The
Travel Charger, which is used to charge the battery, is
included with your phone. Use only Samsung-approved
batteries and chargers.
Note: You must fully charge the battery before using your
phone for the first time. A discharged battery recharges
fully in approximately 4 hours.
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 requires additional charging time.
