iPhone 4 – How to Turn Off and On, Sleep, Wake with iPhone Button

A few simple buttons and a high-resolution multi-touch display make it easy to learn and use iPhone. To learn more about using iPhone’s multi-touch display, go here.

Locking iPhone and Turning It On or Off

When you’re not using iPhone but you still want to receive calls and text messages, you can lock it.

When iPhone is locked, nothing happens if you touch the screen. You can still listen to music and adjust the volume, and use the button on the included stereo headset to play or pause a song, or answer or end a call.

By default, if you don’t touch the screen for a minute, iPhone locks automatically.

To	Do this
Lock iPhone	Press the Sleep/Wake button.
Unlock iPhone	Press the Home button or the Sleep/Wake button, then drag the slider.
Turn iPhone completely off	Press and hold Sleep/Wake button for a few seconds until the red slider appears, then drag the slider. When iPhone is off, incoming calls go straight to voicemail.
Turn iPhone on	Press and hold the Sleep/Wake button until the Apple logo appears.

Adjusting the Volume

When you’re on the phone or listening to songs, movies, or other media, the buttons on the side of iPhone adjusts the audio volume. Otherwise, the buttons control the volume for the ringer, alerts, and other sound effects.

To adjust the volume, use the buttons on the side of iPhone.

Flip the Ring/Silent switch to change between ring and silent modes.

When set to ring mode, iPhone plays all sounds. When set to silent mode, iPhone doesn’t ring or sound any alerts or sound effects (alarms set using Clock do sound). By default, when you get a call, iPhone vibrates whether it’s set to ring or silent mode.

If iPhone is set to ring mode, you can silence a call by pressing the Sleep/Wake button or one of the volume buttons once. Press a second time to send the call to voicemail.
