苹果手机无法关机怎么办

If your iPhone is unresponsive and you are unable to turn it off using the normal method, you can force restart it by following these steps:

For iPhone 8 or later models:
1. Quickly press and release the Volume Up button.
2. Quickly press and release the Volume Down button.
3. Press and hold the Side button until you see the Apple logo.

For iPhone 7 and 7 Plus:
1. Press and hold both the Side (or Top) button and the Volume Down button simultaneously.
2. Keep holding both buttons until you see the Apple logo.

For iPhone 6s and earlier models:
1. Press and hold both the Home button and the Top (or Side) button simultaneously.

This should force restart your iPhone and resolve any issues causing it to be unresponsive.
