To turn off vibration on your iPhone, follow these steps:

  1. Open the Settings app on your iPhone.
  2. Navigate to Sounds & Haptics.
  3. Locate the following options and disable them by toggling the switches to the left (white):
    • Play Haptics in Ring Mode
    • Play Haptics in Silent Mode

Alternatively, if you want to disable all vibrations, including for system feedback and alerts, go to:

  1. Open the Settings app.
  2. Select Accessibility.
  3. Choose Touch.
  4. Find the Vibration option and toggle it off.

Additionally, you can use the Do Not Disturb feature to temporarily silence notifications and vibrations:

  1. Open the Control Center by swiping down from the top-right corner (iOS 15 and newer). For devices with a Home button, swipe up from the bottom of the screen.
  2. Tap the crescent moon icon to enable Do Not Disturb.

Please note that disabling vibrations entirely will also turn off vibrations for emergency alerts.
