About the buttons and switches on your iPhone, iPad, or iPod touch

• Side button (iPhone 6 and later): Press to wake your iPhone or put it to sleep. You can also use the Side button to turn off your iPhone, and with iPhone X or later you can do a few other things.
• Top button (iPhone SE and earlier, iPad, iPod touch): Press to wake your device or put it to sleep. Press and hold the button to turn your device off or on.
• Ring/Silent (iPhone only): Use to mute sounds and alerts on your iPhone. If the switch shows orange, it means your iPhone is in silent mode and will vibrate for incoming calls or alerts. When in silent mode, the alarms you set in the Clock app will still sound, and calls from Favorite contacts will still ring.
• Side switch (certain iPad models): Use to mute sounds and alerts from your iPad or turn Rotation Lock on or off.
• Volume up/down: Use to adjust the volume when listening to music, watching videos, or playing games. When you press the buttons, you'll see the Volume under the indicator. When you're not using other apps, the buttons will adjust the ringer volume and you'll see Ringer under the indicator.
• Home/Touch ID: Use to unlock your device. Press and hold to activate Siri. Press twice from the Home screen or in the app to bring up the App Switcher.
