Learn how to insert or remove the battery on the Apple iPhone 3GS.
Insert / remove battery
The iPhone battery is built into the device and cannot be removed.
If the device menus are frozen or unresponsive, you can soft reset using hardware keys. To perform a soft reset, follow these steps:
- Reset the iPhone by holding the sleep/wake button at the top right of the device and the home button at the bottom center of the face at the same time.
- Hold them both until you see the screen go black.
- Wait until the white Apple logo appears.
- When this happens, you can let go.
- The device will reboot.
