It’s a good idea to turn off your iPhone if the battery is low or if it’s acting strangely, as restarting it can often fix issues, just like it does with computers. In this guide, we’ll show you how to turn off any iPhone and how to perform a hard reset.
Regardless of the reason why you are doing this, below are the steps to turn off an iPhone. This technique applies to most iPhone models, from the original to the latest version.
Press and hold the Sleep/Wake button for a few seconds. Release the button when you see a message appear on the screen. This button is located on the right side of the phone (or on the top or side, depending on the iPhone model).
A power button will appear on the screen with the text 'slide to power off'. Move the slider all the way to the right to turn the phone off.
