Restarting your iPhone is as simple as powering it off and turning it back on again. Here’s how to restart your device for current and older models, and how to force restart if it’s not responding.
How to install the iOS 17 public beta
For iPhone X, iPhone 11, iPhone 12, iPhone 13, or iPhone 14
The iPhone X eliminated the Home button, meaning the side button on the right replaced some of the functions of the Home button, such as waking or putting your iPhone to sleep. So just holding down just the side button doesn’t do anything with newer versions.
To turn off your iPhone X or later, hold the side button and either one of the volume buttons on the left until the power-off slider appears on the screen. Swipe the slider and wait until your iPhone powers off.

To turn your device back on, press and hold down the side button until the Apple logo appears.
For iPhone 6, iPhone 7, iPhone 8, or iPhone SE (2nd or 3rd generation)
For older iPhones that have the Home button, the side button’s primary function was for powering off your device. Press and hold the side button until the power-off slider appears and swipe the slider to turn off the device.

How to force restart your iPhone
