iphone 11 black screen

Sometimes not having the ability to pull out the battery can be a real pain. Thankfully, device manufacturers built in a way to force the phone to restart if it is frozen or stuck on a black screen. We have tutorials on our support pages for many devices so I went ahead and found the one for the iPhone 11 that shows you how to restart the phone when it is frozen. You want step 9 on this tutorial.
