Charging the Battery
Your phone is powered by a rechargeable Li-ion battery. Use the wall charger to
charge the battery, and use only Samsung approved batteries and chargers.
Note: 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.
Note: For connection to an electrical supply outside of the U.S., you must use an adaptor properly
configured for the power outlet. Using the wrong adaptor can damage your phone and void
your warranty.
Note: If the battery level becomes too low, the phone automatically turns off. Recharge your
battery.
