How to Fix an iPhone that Won’t Power Off
Before you try any of these steps, first you should try the standard way of turning off your iPhone. For older iPhone models, hold down the Sleep/Wake button and then swipe the Power Off slider. If you have a newer iPhone, press and hold the Side button and the Volume down button until the slider appears. Drag the slider to turn off the phone. If the standard iPhone restart process doesn’t work, or doesn’t solve the problem, try these four steps, in this order: It’s hard for the average person to figure out whether that’s a problem with the iOS or an app you’ve installed, so the best bet is to restore your iPhone from backup. Doing this takes all of the data and settings from your phone, deletes them, and then reinstalls everything to give you a fresh start. It won’t fix every problem, but it does fix a lot. You can get phone support from Apple (charges will apply if your phone is no longer under warranty). You can also go to an Apple Store for face-to-face help. If you prefer that, be sure that you make an Apple Genius Bar appointment ahead of time. There’s a lot of demand for tech support at Apple Stores and without an appointment, you’ll probably wait a long time to speak to someone.
