how to force restart iphone

To force restart an iPhone depends on the model:

• For iPhone 8 and later models (including SE 2nd/3rd gen):
  1. Quickly press and release the Volume Up button.
  2. Quickly press and release the Volume Down button.
  3. Press and hold the Side (power) button until the Apple logo appears, then release it.
• For iPhone 7 or 7 Plus:
  1. Press and hold both the Volume Down button and the Sleep/Wake (Side) button together.
  2. Keep holding until the Apple logo appears.
• For iPhone 6s, SE (1st gen), or earlier:
  1. Press and hold both the Home button and the Sleep/Wake (Top or Side) button.
  2. Keep holding until the Apple logo appears.

This procedure forces the iPhone to restart without erasing any data. It is typically used when the phone is frozen or unresponsive.
