We love our iPhones, but sometimes they act up. Apps slow down or crash, things don’t run as smoothly as we’d like, or things just get weird — and we don’t know why. Usually, the solution is to power off and restart the device, but if you inexplicably only have 10 seconds to sort out your iPhone’s issues, here’s a handy trick to help you out.

All you have to do is zap your phone’s RAM, and you don’t even have to leave your Home screen to do it.

This tip comes courtesy of Gizmodo (via Marc Forrest), and it couldn’t be more simple. All you do is hold down the Power button on your iPhone until the “Slide to power off” prompt appears. Then, just park your thumb (or finger of choice) on the Home button until the phone bumps you back to the Home screen.

And that’s it. Just make sure your phone is unlocked because otherwise, all you’ll do is open Siri. And Siri can’t quite tell the difference between the words “cache” and “cash,” so it will be no help there.

This isn’t just for iPhones, obviously; it’ll work with any iOS device like an iPad or iPod touch. You shouldn’t need to do it too often, but it’s a decent way to start fresh after you install a new app or notice some weirdness going on with your device.
