Charging a Battery Your device is powered by a rechargeable Li-ion battery. The Travel Charger that is used to charge the battery, is included with your device. Use only Samsung-approved batteries and chargers. 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. Note: You must fully charge the battery before using your phone for the first time. A discharged battery recharges fully in approximately 4 hours. 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. Getting Started 8
