To put your iPhone in Ring mode, move the switch so that orange isn't showing. Ring mode:
To put your iPhone in Silent mode, move the switch so that orange is showing. Silent mode:
On iPhone 7 and later, you can adjust the settings for ringtone and vibration in Settings > Sounds & Haptics. On earlier iPhone models, go to Settings > Sounds.
By default, the volume of ringtones and alerts mirrors the volume you set for audio playback. If you want to control your ringtone and alert volume separately from other apps, turn off Change with Buttons. If you turn off Change with Buttons, you need to manually adjust your ringtone and alert volume in Settings > Sounds & Haptics or Settings > Sounds.
On the same screen, you can choose if you want your iPhone to vibrate when set to ring or silent mode. If you turn off both settings, your iPhone won't vibrate.
