Activating Your Phone
6. Reinstall the battery cover by sliding it back onto the phone until you hear it
securely click. Make sure the battery is properly installed before switching
on the phone.
Charging a Battery
Your phone is powered by a rechargeable Li-ion battery. A travel adapter, which is
used for charging the battery, is included with your phone. Use only approved
batteries and chargers. Ask your local Samsung dealer for further details.
You can use the phone while the battery is charging, but doing so requires additional
charging time.
Note: You must fully charge the battery before using your phone for the first time. A discharged battery
recharges fully in approximately 4 hours.
1. With the battery installed, temporarily remove the plastic cover on the right
side of the phone and plug in the travel adapter’s connector into the jack.
