6 Ways to Fix iPhone Keeps Turning On and Off

If you’re looking for solutions as to why your iPhone keeps turning on and off, we’ve got the answer for you. One of the first steps towards addressing this issue is understanding why it is happening. With that in mind, let’s begin!

Why Is My iPhone Turning On and Off Repeatedly?

Typically, this issue can be witnessed when you restart your iPhone. Instead of it booting up to your Home screen, you see the Apple logo again. This may be caused by one or more factors. Here are the most common ones:

1. Your iPhone failed to properly update. One of the most common reasons an iPhone turns on and off by itself is because a software update was unable to install properly. For example, you may have been attempting to install iOS 17, but something interrupted this process. This may be why your iPhone keeps turning on and off.
2. Your iPhone may have a hardware problem. You may be experiencing issues with your iPhone turning off randomly due to a physical problem with your device. For example, you may be experiencing a problem due to water entering your battery. The battery may also simply be unable to hold a charge.
3. An app may be causing issues. Along with hardware issues, software issues may be causing problems as well. There may be an app on your iPhone that is causing significant battery drain.
4. You may be experiencing a malware attack. While unlikely, it is possible that you are the victim of a malware attack. While this typically only occurs when you are doing something nefarious with your iPhone, there is a slim possibility that you received an attack while using your iPhone normally.

3. Check Your Battery Health and Drain Your iPhone

NOTE

You can easily check your iPhone’s battery health via Settings > Battery. You can also click Battery Health & Charging within this setting for more information.

Another option is to drain your iPhone battery completely. This can be a good solution if you find that your iPhone is shutting off with battery left. If there is a small software glitch occurring with your iPhone or battery, you’ll be fine. However, if there is a larger issue present, you may need a stronger solution. You may also want to consider some charging tips.

1. Simply allow your iPhone battery to drain completely. Essentially, you are waiting for your iPhone to shut down on its own due to lack of power.
2. Once the iPhone is completely dead, connect your charger to the device.
3. Wait for the battery to fill completely to see if this fixes your issue.
   

4. Update iOS System

If you find yourself asking “Why does my iPhone keep turning off and on by itself?” then try checking for a software update to see if this fixes any potential issues. While not always a guarantee, there are times when a software update to your device can fix any potential bugs or small errors occurring within your iPhone.

1. From your iPhone, navigate to Settings.
2. Select General.
   
3. Tap Software Update. If one is available, tap on it and follow the instructions on-screen.
   

5. Uninstalling Unused Apps

NOTE

If you are using iOS 11 or later, your iPhone should be deleting unused apps automatically. Ensure this feature is enabled via Settings > App Store > Offload Unused Apps.

App bloat, or having way too many unused apps, can often cause problems for your device. For example, an app you no longer use may be using resources without you fully realizing it. However, be aware that if you’re trying to solve a problem wherein your iPhone turned on and off by itself, this may not fix your specific issue unless an app is giving you problems.

Fortunately, deleting unused apps is super easy:

1. From your Home screen, long-press on an app you want to remove.
2. A pop-up should appear. Select Remove App.
   
3. Select Delete App.
   
4. Choose Delete App again to confirm.
   

Alternative Solutions When All Methods Have Failed

If all of the above solutions have failed, your unfortunate last resort is to contact Apple Support. While this is not the ideal situation, this is likely one of the only solutions left if you tried everything above. It is likely that you are experiencing a hardware problem or a software problem that only Apple or an Apple Specialist is capable of fixing.

Final Words

Being in a situation where your iPhone keeps turning on or off even when you have battery left can be tough. Considering how essential our devices can be in this day and age, the only solution is to have a device that works when you need it to. Following the troubleshooting steps outlined above, you should be able to get your device performing as expected.
