Part 1. Why iPhone XR/11/12 Would Not Turn Off
There are many possible reasons why your iPhone cannot turn off. This part will deeply dive into understanding the four common reasons why the iPhone is not turning off. This section will focus on iPhone XR, 11, and 12.
1. You Used the Wrong Way To Turn Off iPhone
A possible reason your iPhone is not turning off could be that you are doing it wrong! Here is a quick and simple tutorial on how to turn off iPhone XR, 11, or 12.
Step 1. Press and hold the Side button and the Volume Up or Volume Down button until the slider appears.

Step 2. Tap the off icon on the top left and drag the slider to turn off your iPhone.
Note
If you follow the steps and do not see the screen above, there may be a system crash or a broken power button. Do continue to read on the understand the different problems.
2. System Crash
When your iPhone suddenly experiences a system crash and becomes unresponsive, it indicates that the system is going haywire. When this happens, you will not be able to do anything to your screen as it typically will just show a frozen black screen. The phenomenon affects the powering-off process as the buttons become unresponsive, and you won't be able to initiate the power-off page.
3. The Power Button Is Broken
It is uncommon for iPhone users to experience a broken Power button, resulting in the inability to perform the power-off steps on the iPhone. There are several possible reasons why your Power button is not working. A software glitch that causes the Power button to be unresponsive or physical damage that impacts the Power button could be possible reasons.
Sometimes you might suspect the Power button is broken, but it is not. Phone cases interfering with the Power button or dirt accumulated around it could have caused the Power button to be stuck. A simple swap in an iPhone case or cleaning will do the trick.
4. The Screen Is Broken and Unresponsive
Your iPhone screen will prompt you to slide the power-off slider to turn off your iPhone. However, if your screen is broken or unresponsive, you will not be able to see the power-off slider or screen. Reasons such as an old iOS version, physical damage to the screen, or too many files/apps could be why your iPhone is unresponsive.
Part 2. 5 Best Methods To Fix iPhone XR/11/12 Not Being Able To Turn Off
After understanding the common problems on why your iPhone is facing issues with turning off, here are sharing some simple and quick solutions that could help fix the problem.
1. Hard Reset Your iPhone
If your iPhone cannot turn off, a quick and easy way to check if anything is wrong is to perform a hard reset. Follow the steps below to perform a hard reset.
Step 1. Press and release the Volume Up button.
Step 2. Press and release the Volume Down button.
Step 3. Press and hold the side button.

Step 4. Wait for the Apple logo and release the side button.
2. Try AssistiveTouch
If your Power button is not working and you desperately need to turn off your phone, you can try the AssistiveTouch function. AssistiveTouch is a feature on iPhone that mimics the Home button but with more functions.
Step 1. Go into Settings > Accessibility > Touch and tap the AssistiveTouch button. Tap the switch to turn it on, and you should see a small circle on your screen.
Step 2. Tap on this circle and go into Device > More > Restart. Confirm that you want to restart your iPhone. After your iPhone restarts, check your Power button again to see if it works.

Step 2. Once the setting is reset, try turning off your phone again.
Note
Resetting settings remove all settings and rest them to their defaults. Your media and data are still safe.
