If your iPhone is giving you trouble, a simple reboot is a quick way to fix the problem. But what if your device is frozen and you can’t get to the standard “slide to power off” screen?

There are a few different ways to power off and/or reset your iPhone, and we’ve got step-by-step instructions for all the different iPhone versions below. If you’re still unable to power off or reset your device, you may need to head over to your nearest Apple Repair Center for more assistance. Of course, you could also wait until the battery dies, but that solution can take some time – it’s not an everyday fix you want to have to deal with.

This is the basic method for powering down your modern iPhone. It can fix some common performance issues, like slow apps or spotty Wi-Fi.

Press and hold the Side button and Volume Down button until the power off slider appears on the screen.
