How do I install or remove the Battery Cover and Battery for my Samsung Galaxy S III?
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 batteries and chargers approved by Samsung. You must fully charge the battery before using your device for the first time. A discharged battery recharges fully in about four hours. Although you can use the device while the battery is charging, doing so will require additional charging time.
