Fully charging your new iPhone is the first thing you should do once you return home with your new phone. The iPhone is a touch screen smartphone manufactured by Apple. It has a rechargeable lithium-ion battery. When fully charged, the battery will last up to 250 hours if the phone is not used, or approximately 6 to 8 hours if being used for web surfing or talking. The iPhone can be charged using a computer or the included USB power adapter.
Plug the Dock Connector to USB Cable that came with the iPhone into the dock connector slot on the bottom of the iPhone. Continue to the next step if you wish to charge your iPhone using a computer, or skip to step 3 if you wish to charge your iPhone using the USB power adapter (wall charger) included with your iPhone.
Plug the Dock Connector to USB Cable into a computer that is turned on and not in standby or sleep mode. Go to step 4.
Plug the Dock Connector to USB Cable into the USB port on the USB power adapter that came with the iPhone, then plug the USB power adapter into a wall outlet.
