DoubtUser Concern

“I woke up this morning, and my iPhone 14 just kept restarting randomly, even when I wasn't on my phone. I've updated to iOS 17 and it's continuing. I don't know how to stop it. Any suggestions?”

Hey, It's Joan here again. I am an Apple expert and am interested in researching all tips and tricks about the iPhone/iPad. Thanks for visiting my website.

iPhone restart issues mostly happen with old devices, but sometimes, it can happen on newer iPhones like iPhone 15 or iPhone 14, too. I can feel the frustration when getting an iPhone keeps restarting itself.

Why does it happen, and what should you do? Give it away or take it to the Apple Store? In this guide, I will walk you through this problem and how to resolve the iPhone keeps restarting issue. Let's check out.

Why is My iPhone Continuously Restarting?

From what I have experienced, there are two scenarios in the iPhone keeps restarting:

  • iPhone restarts intermittently: You can access and use your iPhone for a while, but it suddenly restarts after a few moments.
  • iPhone restart loop: The iPhone continuously restarts over and over again and you can't access and use the device at all.

There could be plenty of reasons for the iPhone keeps restarting itself. Below are some common factors that often cause this issue:

  • Bad Updates: The iOS update process was interrupted for network interruption or other unknown reasons, which might result in the iPhone keeps restarting error.
  • Software Bugs: Some unexpected bugs and glitches in iOS or any other software can cause various issues, including the iPhone randomly restarting.
  • Malware Attack: You may jailbreak your iPhone to install apps from third-party sources, which makes it easy to install malware and get security threats.
  • Problematic Apps or Insufficient Storage can often cause the iPhone to restart itself.
  • Hardware Issues like iPhone water damage or component failure might also cause the device to restart continuously.

Attention: Back Up Your iPhone First!

Before making any fixes, ensure your iPhone data is backed up. Then, you won't lose important data like photos, messages, contacts, etc.

If you can access your iPhone, you can easily back up the device using iCloud. If not, you can try connecting your iPhone to a computer and making a backup with iTunes/Finder or third-party tools like FoneGeek Backup & Restore (iOS).

How Do I Stop My iPhone from Restarting Loop?

Tip 1. Force Restart Your iPhone

Force restarting an iPhone is usually the first and most time-saving method when the device has a software bug. Depending on the device model, here's how to force restart an iPhone.

  • iPhone 8 or Later: Quickly press and release the volume up button, then press and release the volume down button, and finally, keep pressing the side button for a while until the Apple logo appears.
  • iPhone 7 or iPhone 7 Plus: Keep pressing and holding volume down and power buttons at the same time until the device turns into an Apple screen.
  • iPhone 6S or Earlier: Press and hold the power button and the home button together for a few seconds until the Apple logo appears on the screen.

Tip 2. Update Outdated Apps

Some outdated apps can dramatically decrease battery life and cause the iPhone to crash and restart. If you find these apps installed on your iPhone, go to App Store > Updates and tap Update All, or choose the apps you want to update one by one.

Tip 3. Check and Uninstall  Faulty Apps

In most cases, iPhone or iPad restarts randomly due to faulty apps. If your iPhone keeps restarting after you install a specific app, try to uninstall the problematic app and then check whether the bug can be removed.

In addition, Apple provides a feature called "Analytics" that effectively diagnoses issues on the iPhone. If you are not sure which app causes the restarting, you can go to Settings > Privacy > Analytics Data to check for problematic apps. If you find any app in the list, just uninstall it to solve the restarting issue.

Tip 4. Turn Off Background App Refresh

If the Background App Refresh of some apps is enabled, the content will be updated automatically when the device is connected to WiFi or cellular data in the background, which puts a lot of pressure on the iPhone or iPad.

In such a situation, it's necessary to turn off the Background App Refresh of some apps that you don't need. To do so, navigate to Settings > General > Background App Refresh and turn it off.

Tip 7. Clean Up iPhone Storage

If you don't take good care of your iPhone, its performance will be affected even if the storage is 256GB. So one of the best ways to keep the device running smoothly is to clean the app cache and redundant data. Uninstalling useless apps or using some handy cache cleaner apps can help a lot.

Tip 8. Reset All Settings

If your iPhone still keeps restarting itself, you can try to reset all settings. This proves to be helpful in solving various problems on iPhone.

To restore your iPhone's settings to factory defaults, go to Settings > General > Transfer or Reset iPhone > Reset and choose Reset All Settings. You won't lose any data, but you will need to enter your Wi-Fi password again.

  1. Connect your iPhone to your computer and launch iTunes (or Finder in macOS Catalina).
  2. Locate your iPhone and click on Restore iPhone.
