苹果怎么重启手机

To restart an iPhone, you can follow these steps:

1. Press and hold the power button (also known as the side button or sleep/wake button) located on the right side of the device.
2. While continuing to hold the power button, simultaneously press and hold either the volume up or volume down button.
3. Keep holding both buttons until the "slide to power off" slider appears on the screen.
4. Release both buttons, then swipe the slider from left to right to turn off the iPhone.
5. Once the device is powered off, press and hold the power button again until the Apple logo appears on the screen, indicating that the iPhone is restarting.

This process may vary slightly depending on the model of your iPhone, but these general steps should work for most devices.
