Restarting iPhone X,11, 12, 13, andlater

If you want to restart a modern phone, press and hold the buttons Captain Kirk and Mr. Spock are pointing to.

A slider should appear. Drag the slider and give the phone about half a minute to turn off. If it doesn't, your phone might be frozen. There are some tricks to force-restart a frozen device, which Apple discusses.

Once your phone is powered off, turn it back on. You'll need to press the button on Spock's side, and hold it until you see the Apple logo.

Restarting iPhones 6, 7, 8, and the new SE style

If you have a slightly older generation phone, it's Batman to the rescue.

Press and hold the side button the Caped Crusader seems to want to blam, pow, and kapow. As with the more modern phones, a slider should appear. Drag the slider and give the phone about half a minute to turn off. If it doesn't, your phone might be frozen. Try to force-restart your frozen device.

Once your phone is powered off, turn it back on. You'll need to press (not punch) the button on Batman's side and hold it until you see the Apple logo. I don't know what it is about him, but from that expression, I get the impression the Dark Knight needs more fiber in his diet.

Restarting even older iPhones

Did you seriously think the Man of Steel would stay away from our iPhone restart extravaganza? Of course not.

Here, Supes is pressing down on an older generationiPhone SE . The power button is located on the top of the unit, as it is for other older iPhones. By now, you know the drill. Press and hold that button until a slider appears. Drag the slider and give the phone about half a minute to turn off. If it doesn't, your phone might be frozen. Try to force-restart your frozen device.

Once your phone is powered off, turn it back on. You'll need to press that top button Superman is floating over, and hold it until you see the Apple logo.

A quick thanks for the super-assist

So there you go. Restarting your phone should be quick and easy. A special shoutout goes to our friends at The Noble Collection, who helped us book photo sessions with the fab four above. Last year, they sent usKirk , Spock , Batman , and Superman BendyFigs with the hope we'd use them as some sort of prop or another. You've got to admit, they were a lot more fun than just Photoshopping a red arrow over the buttons, right?

Anyway, there you go. Do you have any other how-to requests? Let us know in the comments below.

Live long and prosper. Up, up, and away!
