Is your iPhone constantly restarting on a loop? All you can see is the Apple logo appearing and disappearing on the screen, and you can no longer use it. Don’t worry, there are ways to hurdle this obstacle.

But before we guide you through the fixes, let’s find out why this problem is occurring in the first place.

Why Does My iPhone Keep Restarting?

There are several reasons why you are experiencing this problem. Perhaps your phone’s connection to your wireless carrier is unstable.

It can also be that your iPhone is jailbroken, so it’s affected by a malware attack. Interrupted software updates can cause this issue too.

When your iPhone malfunctions for the mentioned reasons or otherwise, your iOS can get stuck in a boot loop. Read on to learn how to fix your iPhone that is stuck in a restarting loop.

Let’s begin!

Back up Your iPhone.

Before we start with any troubleshooting, we recommend that you back up your iPhone first to avoid losing any important data along the way.

You can do this with iCloud and through your Mac or PC. If you need help, you can visit Apple Support, and they will provide you with all the details you need.

Force Restart Your iPhone.

Try to do a force restart on your iPhone. This will not delete any important data on your iPhone, but it will clear junk and corrupt files that can cause the system to crash. There are different ways to do a force restart.

  1. iPhone 6s and older: Press and hold the Sleep/Wake button and Home button until the Apple logo appears. Then, release both buttons.
  2. iPhone 7 and 7 plus: Press and hold the volume down button and the Sleep/Wake button simultaneously. Release when the Apple logo appears on the screen.
  3. iPhone 8 and newer: First, press and release the volume up button. Then, press and release the volume down button. Next, press and hold the side button. Lastly, release the side button when the Apple logo appears.

Determine if an App is Causing Your iPhone to Restart.

If you recently installed an app before your iPhone went into a restarting loop, uninstall that app. Check if this will resolve the problem.

You can always check Analytics Data to see if there are problems with an app. To do this, follow the steps below:

  1. First, launch the Settings app on your phone.
  2. Then, go to Privacy and select Analytics & Improvements.
  3. Finally, click Analytics Data.

There will be several entries on the list. Scroll down and look for any apps that are listed several times. If you find one, uninstall that app.

Install Pending Updates for Apps and iOS.

Regularly updating the apps and iOS helps fix the bugs and brings in new features for your iPhone. Before updating the apps and iOS, keep in mind the following:

  1. You should have a stable internet connection
  2. Your storage should be sufficient for updating/installing the downloads
  3. When updating iOS, your battery juice should be at least 50% or your iPhone should be connected to a power source

To update your apps, follow these steps:

  1. First, launch the App Store on your iPhone.
  2. Next, click your account icon on the top right part of the screen.
  3. Scroll down to see the Available Updates. Then, click Update All.

Install Pending Updates for Apps

To check for an iOS update, do the steps below:

  1. First, launch the Settings app on your phone.
  2. Then, go to General and then tap Software Update.
  3. Click Download and Install if there is an available download.
  4. Wait for the download and installation to finish.

Once you’re done, reboot or soft reset your iPhone. This will refresh the apps and system services.

Reset All Settings.

Resetting all settings is recommended if your iPhone is acting up after installing a new iOS update. Don’t worry because this will not delete any data on your device. This will only reset all settings, including network, privacy, location, and others.

These are the steps on how to reset all settings:

  1. Start by opening the Settings app on your iPhone.
  2. Then, tap General.
  3. Scroll down and tap Reset. It’s located on the bottom part of the screen.
  4. Then, select Reset all Settings.
  5. Next, enter your device passcode, and click confirm that you want to reset all settings on your iPhone.

Wait for the reset to finish. Your iPhone will restart automatically, and all default setting options are now applied to your iPhone.

Observe if your iPhone still keeps restarting after doing this method.

Remove Your SIM Card.

As we mentioned at the start of this article, one of the reasons why your iPhone keeps restarting on a loop may be caused by an unstable connection to your wireless carrier. And since the SIM card directly connects your iPhone to your wireless carrier, removing it can fix your problem.

You will need a paperclip or something small and pointy to eject the SIM tray from your iPhone. Removing a SIM differs on each iPhone model, and Apple will guide you through that.

Safely unplug your iPhone on the Mac/PC. If the problem still exists, you can click on the Try Again button.

Restore Your iPhone in DFU Mode.

If the problem still occurs even after a system repair, try restoring your iPhone in DFU mode. A Device Firmware Update (DFU) is considered the deepest type of system restore on an iPhone, and it can repair an iPhone with a corrupt iOS.

Restoring in DFU mode differs depending on which iPhone model you are using. For iPhone 6s, SE, and earlier models, these are the steps:

  1. First, connect your iPhone to a Mac or PC using the lightning cable.
  2. Once it’s connected, hold the Home button and Sleep/Wake button for 8 seconds.
  3. Then, release the Sleep/Wake button, but continue to hold the Home button until the screen is entirely black.

If the Apple logo appears, it means you’ve held down the Sleep/Wake button longer than necessary. You need to start from step one again.

For iPhone 7 and 7 Plus users, these are the steps to enter DFU mode:

  1. Start by connecting your iPhone to a Mac or PC using the lighting cable.
  2. While the device is connected, hold both the Sleep/Wake button and volume down button for approximately 8 seconds.
  3. Then, let go of the Sleep/Wake button but keep holding down the volume down button.

The Apple logo will appear if you’ve held down the Sleep/Wake button longer than necessary. The screen should remain black. This signals that your iPhone has entered DFU mode and is now ready for iTunes restore.

For iPhone 8, 8 Plus, X, and later models, these are what you need to do:

  1. Connect your iPhone to a Mac or PC using a lightning cable.
  2. Press and release the volume up button while the device is connected.
  3. Next, quick-press and release the volume down button.
  4. Then, press and hold the side button until the screen turns black.
  5. Immediately hold down both the side button and volume down button for about five seconds.
  6. Finally, release the side button while still holding the volume down button. Do this until nothing is displayed on the screen.

Once you’ve entered the DFU mode, you can continue restoring your iPhone via iTunes. Make sure that your iPhone is connected to the Mac or PC the entire time to avoid errors during the restoration process.

Check For a Hardware Problem.

Now that we’ve checked and did some troubleshooting for possible software-related problems, you can also check if the problem is caused by malfunctioning hardware.

If your battery is already worn out, you can replace the faulty battery by bringing it to an Apple service center. If your iPhone keeps restarting even while charging, check if your lighting cable still works. Otherwise, try using another cable to charge your device.
