Have you ever been frustrated that your iPhone keeps restarting? It can be quite bothersome when we are engrossed in an app or an important task, and suddenly our iPhone keeps restarting itself. Not only does it interrupt our work or entertainment, but it can also result in data loss or other inconveniences.

In general, the reasons that can cause an iPhone to keep restarting are as follows:

  • Software issues: errors or conflicts in the iOS system or applications
  • Hardware problems: battery issues, faults in the power management chip, or other internal component failures
  • Overheating: prolonged usage under high load, exposure to high temperatures, or blocked device ventilation
  • Insufficient storage space: the device's storage space is nearly full
  • Viruses or malware: the device becomes infected

While the reasons may vary, this post will introduce you to 8 practical methods to solve the issue of your iPhone keeps restarting over and over. It will cover everything from simple software adjustments to troubleshooting hardware problems. Let's take a look at these methods together!

My iPhone Keeps Restarting: Two Symptoms

Based on the symptoms and causes, iPhone keeps restarting issues can be categorized into two types: intermittent restarts and continuous loop restarts.

Symptoms of Intermittent iPhone Restarts

  • The iPhone spontaneously restarts during usage, but not frequently.
  • After restarting, the iPhone generally functions normally for a period before automatically restarting again.
  • There might be signs of app crashes or device slowdowns.

Symptoms of Continuous Loop iPhone Restarts

  • The iPhone gets stuck in an infinite loop displaying the Apple logo during the startup process.
  • The device turns off abruptly after starting up, displays the Apple logo again, and restarts the cycle repeatedly.
  • This looping process continues endlessly, preventing normal access to the device's user interface.

Regardless of which method you choose to fix iPhone keeps restarting, we recommend you perform a data backup first. This ensures that your important data is safely stored in case any unforeseen issues occur during the troubleshooting process.

How to Fix iPhone Keeps Restarting Intermittently

If your iPhone is experiencing intermittent restarts and you have access to the operating system, there's no need to worry too much. This situation is usually caused by some software issues or external factors. These problems can be easily resolved, and you can try the following 3 methods as a first step:

1. Update iOS and Apps

Updating iOS and apps can solve intermittent restart issues on your iPhone by fixing software bugs, improving compatibility between apps and the operating system, and providing security patches to prevent malicious activity that may cause unexpected restarts.

  2. Scroll down and tap on "General".

How to Fix iPhone Keeps Restarting Loop

If your iPhone is stuck in a continuous loop of automatic restarts and you are unable to operate your phone or even if your iPhone fails to start up, the previously mentioned methods may not be applicable. In such cases, you will need to resort to more forceful measures to resolve the issue of iPhone keeps restarting.

4. Force Restart

Firstly, you can try Force Restarting your iPhone. While a Force Restart may not resolve all issues, it is a simple and commonly used troubleshooting method to stop your iPhone from keeping restarting.

The method to force restart an iPhone varies depending on the model you have. You can follow the corresponding steps below to force restart your iPhone:

# For iPhone 8 Series and later (including iPhone SE 2nd)

  1. Press and let go of the Volume Up button, and then the Volume Down button.
  2. Press and hold the Side button.

5. Check the Hardware

Another potential cause of the iPhone restarting loop problem could be some hardware issues:

  • A worn-out battery: If the battery of your iPhone is identified as the culprit, you can resolve the issue by simply replacing the faulty or worn-out battery.
  • An unclean Lightning port: If your iPhone keeps restarting while charging, make sure the Lightning port is clean. Remove any pocket lint, dirt, or debris that may have accumulated, as it can hinder the charging process. After cleaning the charging port, try charging the device again. If the problem continues, attempt charging with a different cable.
  • Frequent drops: If your device has recently experienced a significant drop, it's possible that there could be a hardware problem causing your iPhone to get trapped in a restarting loop. And if the damage is severe, it's recommended to contact Apple Support or visit an authorized service center for help.

6. Pull out Your SIM Card

A connection issue with the wireless carrier can also be the reason for trapping your iPhone in a restart loop. A simple and effective solution is to remove and reinsert the SIM card. Here's how you can do it:

  1. Power off your iPhone completely.
  2. Insert the ejector tool (or a small safety pin) into the SIM card tray slot to eject it.
  3. Take out the SIM card from the tray.
  4. Wait for a few seconds and then place the SIM card back into the tray.

7. Restore Your iPhone

If you reach this point, there is still one ultimate solution for you to address the issue of iPhone keeps restarting: restoring your iPhone with iTunes. This method can often resolve persistent software issues that may be causing the restart problem.

However, it's important to proceed with caution as restoring your iPhone will erase all data on it. Therefore, it is highly recommended to back up your important data beforehand to ensure its safety. Here are the specific steps to restore your iPhone:

Step 1. Connect your restarting iPhone to a computer with the latest version of iTunes installed(for Windows and macOS Mojave and earlier), or with an opening Finder (for macOS Catalina and later).

Step 2. Put your iPhone into Recovery Mode.

Step 3. Once your computer successfully recognizes your device, you will be presented with two options: "Restore" or "Update". Click on the "Restore" button to begin the restoration process.

Step 4. Follow the on-screen instructions and wait for iTunes/Finders to complete the restore process.
