The iPhone goes to sleep by default after it's been inactive for a certain period of time. But even though the iPhone consumes much less battery life when it's asleep, there may be circumstances--especially when the phone's battery is particularly low--in which you want to completely turn off iPhone.
Here's how you do it:
- Start by holding down the sleep/wake button at the top right-hand corner of the iPhone for a few seconds.
- This will bring up a screen asking you to run the slider across the screen to turn off the iPhone.
- If you don't want to do this, just tap the cancel button at the bottom of the screen.
- If you do, though, move the slider to the right. When you do, a progress wheel will appear and in a second or two, the iPhone will turn off.
- To turn it back on again, just hold down the sleep/wake button again until the Apple icon appears on the screen.
- Then let the button go and then wait for the phone to start up.
