How do I install or remove the Battery Cover and Battery for my Samsung Galaxy S III?
You must fully charge the battery before using your phone for the first time. A discharged battery recharges fully in about four hours.
Charging a Battery
Your device is powered by a rechargeable Li-ion battery. The travel charger used to charge the battery is included with your device. Use only Samsung-approved batteries and chargers.
Although you can use the phone while the battery is charging, doing so will require additional charging time.
