iPhones crash sometimes. Usually, this is caused by RAM issues and can be solved by clearing some cache and relaunching the heavy application that lagged.

That being said, when your iPhone has been crashing and also restarting persistently, there may be more underlying issues.

We know how frustrating it is. But don’t worry because in this article, we will teach you different ways to address the problem.

Why Does Your iPhone Keep Crashing?

Frequent crashing of your iPhone indicates possible problems on the system’s end.

This can be caused by bugs in the operating system (OS), malfunctioning applications, or insufficient memory to run processes.

Whatever the reason is, and as long as it’s not hardware-related, the methods below may be able to solve it.

Now let's get started!

1. Back up Your iPhone

First things first. Make a backup of your important files as some of the troubleshooting methods below may delete your data.

There are different ways on how to do this. We recommend that you visit Apple Support to guide you through this process.

2. Restart Your iPhone

A simple restart can solve many minor issues of your iPhone like frequent crashing. This will refresh all its system components especially if you’ve been using your device for a while.

The steps on how to restart your iPhone depends on its model.

For iPhone X, 11, or 12:

  1. Press and down the side button and any of the volume buttons until the power off slider shows.
  2. Next, drag the slider to the right and your phone will turn off in 30 seconds.
  3. Afterwards, turn your phone back on by holding down the side button.

Here are the steps for iPhone SE (2nd gen), 8, 7, or 6:

  1. Hold down the side button and release it once the power off slider appears.
  2. To turn off the phone, drag the slider. Wait 30 seconds for your device to shut down completely.
  3. After that, turn your device on by pressing and holding down the side button until the Apple logo appears.

Suppose your device is iPhone SE (1st gen), 5, or earlier:

  1. First, press and hold the top button until you see the power off slider.
  2. Right when you see the power off slider, drag it to turn your phone off.
  3. Finally, press and hold the top button to reactivate your iPhone.

If you’re unable to perform a normal restart because your iPhone keeps crashing along the process, try doing a hard reset instead.

3. Hard Reset Your iPhone

Unlike the usual way of restarting, hard resetting your iPhone forces the device to shutdown and immediately turns it back on automatically.

Use this method to clear out temporary and also corrupted files that may cause your device to crash. Your iPhone will not lose any important data during this process.

You should only do a hard reset on your iPhone if you can’t reset it the normal way. Read here if you want to know more about the difference between a hard reset and a normal reset.

There are also different ways on how to do a hard reset for your iPhone depending on the model you have.

  1. For iPhone 8 and later versions: The first thing you need to do is to press and release the volume up button. Then, immediately press and release the volume down button. Finally, hold down the side button until the Apple logo appears.
  2. For iPhone 7: Hold down both the Sleep/Wake button and the volume down button simultaneously. Wait until the Apple logo appears and release both buttons.
  3. If you’re using iPhone 6s, SE (1st gen), or earlier: Press and hold down both the Home and Sleep/Wake buttons at the same time until you see the Apple logo on your screen.

4. Clear Memory/Storage on Your iPhone

Your iPhone may have insufficient memory to run all its programs. As a result, it can face various problems like frequent crashing.

To ensure that your device always has enough memory, make a backup of your important files.

Afterwards, delete those that are no longer needed and also uninstall the unnecessary apps.

You can check the available storage of your iPhone on the Settings. From here, select General and tap on Storage.

Make sure that you always have at least 1GB of memory in your iPhone for system use.

5. Reinstall or Update an App on your iPhone

If your phone only crashes when you launch a certain app, the application probably contains bugs or is incompatible with your device. Try updating or reinstalling the application and check if the issue still persists after doing so.

Here’s how you can perform a manual update for your apps:

  1. Launch the App store.
  2. Navigate to your profile by tapping the profile icon on your screen.
  3. Scroll down until Available Updates.
  4. Tap on the Update button next to an application to update it. Alternatively, you can tap Update All to update all your apps.

Install Pending Updates for Apps

If your iPhone is still crashing even after updating the application, try deleting the app and reinstalling it again through the Apple Store.

6. Update Your iPhone Software

Aside from third-party applications, your iPhone’s own software may also contain bugs and corrupted files causing your device to crash. Keep your iOS updated to eradicate these issues.

If there’s a pending update, you will get a notification on the Settings app so make sure to visit it once in a while.

Follow these steps to update your iOS:

  1. Plug in your device into a power supply as this process may take some time.
  2. Connect your device to the internet and make sure that you have a stable connection throughout the process.
  3. Next, launch the Settings app on your phone.
  4. Navigate to the General section and select Software Update.
  5. Finally, click Download and Install, and wait for the process to complete.

7. Use TinyFix iOS System Repair

In addition to your iPhone’s built-in features, you can also count on a third-party app called TinyFix iOS System Repair. This application can fix the crashing issue of your device without losing any data.

  1. Download and install the TinyFix iOS System Repair tool to your computer.

8. Restore Your iPhone from an Old Backup

If none of the previous methods work, maybe it’s time to consider restoring your iPhone to its previous state, when it was working smoothly.

Keep in mind that you can only do this if you have previously made a backup of your iPhone.

To restore your device from an older backup, follow these steps:

  1. Using a USB cable, connect your iPhone to your Mac or PC.
  2. Launch the iTunes program on your computer.
  3. On the iTunes interface, click the Device button on the top left part of the interface and click Summary.

9. Put Your iPhone In DFU Mode

Your last resort is to perform a DFU (Device Firmware Update) restore. We recommend that you only use this option if you’ve exhausted all other options already.

This will erase all your files and restore your device’s system to its fresh state.

There are different ways to put an iPhone in DFU mode, depending on its model. First, connect your phone to your computer via a USB cable. Then, follow the steps outlined below.

For iPhone 8 or later models:

  1. Press and quickly release the volume up button.
  2. Right after releasing the volume up, press and release the volume down button.
  3. Afterwards, hold down the side button until the screen turns completely black.
  4. Next, you need to hold down both volume down and side button for five seconds.
  5. Finally, release the side button while holding the volume down button. If your screen doesn't display anything at this moment, it means that it is now in DFU mode.

If you’re using iPhone 7 or 7 Plus:

  1. Press and hold down both side and volume down buttons simultaneously. Hold them for about 8 seconds.
  2. After 8 seconds, release only the side button. If the screen doesn’t display anything, your device is now in DFU mode. If you see the Apple logo instead, you have to repeat the process.

For iPhone 6s, SE, or earlier models:

  1. Press and hold the Sleep/Wake and Home buttons at the same time for 8 seconds.
  2. Then, you need to release the Sleep/Wake button while still holding the Home button. Hold it until the display turns black.

As soon as your iPhone enters DFU mode, restore it using the iTunes application on your computer.
