It's easy (and annoying) to be distracted by your phone's alerts and incoming calls. Follow this tip on turning on your iPhone's silent mode if you need some peace and quiet but don't want to enable Do Not Disturb. Here's how to put your iPhone's ringer on silent while the baby is napping or you're watching a show, or if you just find the sound of a phone ringing unpleasant.
Push the switch back so the orange shows.
Your iPhone is now in silent mode. This means calls and alerts will be muted. Alarms set in the Clock app will not be muted.
To turn silent mode off, simply push the switch forward so the orange no longer shows.
You can still be alerted to calls and notifications if you have Vibrate on Silent on. But if you don't want your device to make even that much noise, you can also shut off the vibration feature.
Open Settings and tap Sounds & Haptics (or Sounds if your iPhone is earlier than iPhone 7).
Toggle Vibrate on Silent to off.
