How Do I Reboot My iPhone 8?

If your iPhone 8 or iPhone 8 Plus is frozen up, behaving oddly, or if you're running into some temporary glitches, rebooting your iPhone 8 will help.

Rebooting an iPhone 8 or 8 Plus, a process also known as a "soft reset," is very easy. You can try a reboot basically any time your iPhone is frozen up, behaving strangely, a feature isn't working as expected, or an app is crashing. If you need to restart, just follow these steps:

  1. Press and hold the side button on the right edge of your iPhone 8 until the Slide to power off slider appears.

  2. Move the slider from left to right.

  3. Wait 15-30 seconds as your iPhone 8 shuts down.

  4. When the iPhone is shut down, reboot the iPhone 8 by holding down the side button.

  5. When the Apple logo appears, release the side button and let the iPhone reboot.

What Does a Soft Reset Do on iPhone 8?

When you soft reset, aka "restart" or "reboot," an iPhone 8 or 8 Plus, you clear out the iPhone's active memory. This isn't the memory that's used to store your photos, apps, music, and other data. Instead, this is the memory that apps and iOS use to operate. It's also the memory where temporary problems can occur.

When you soft reset an iPhone 8, you clear out the active memory and let the phone start up again with cleared memory. If problems have been happening in the active memory, clearing it out usually fixes them. The reset doesn't erase any of the data in the permanent storage, though, so you don't have to worry about losing important stuff.

Why Won't My iPhone 8 Reboot? 

In some cases, an iPhone 8 or 8 Plus may be having a more serious problem preventing it from rebooting. You'll know you're having this problem when you can't follow the steps to reboot the iPhone listed earlier in the article. This can happen for any number of reasons, but usually, the problem is with your operating system or the hardware in your iPhone.

Even if that's happening, though, you can still reboot. You just need to use a different process, called a "force restart" or a "hard reset." This won't delete any of your data, either, and can help fix a tougher glitch.

To hard reset your iPhone 8, follow these steps:

  1. Press and release the Volume Up button

  2. Press and release the Volume Down button.

  3. Press and hold the side button.

  4. The iPhone 8 screen will go black. When the Apple logo appears, release the side button and let the phone restart.
