How to fix an iPad, iPhone iOS 13 that suddenly reboots when idle

One of the major problems anyone could encounter after installing system updates is on unexpected system crashes and reboots. These are tagged as major issues because it involves the core system functions. Tackled in this post is a relevant issue transpiring on an iPad and iPhone after the iOS 13 (beta) update implementation. To address the problem, I’ve also mapped out some applicable workarounds and potential solutions that can be used as free reference for those who need more input in resolving the same post-iOS 13 update issue. Read on for more information.

First solution: Force restart your iPhone iOS 13.

Your iOS device might have been stuck on random reboots or infinite bootloops after the iOS 13 update implementation. And the easiest potential solution to stuck problems in iOS devices is a forced restart. If you haven’t already, then this should be considered as the first workarounds to apply.

To force restart an iPhone or iPad with a physical Home button, simply follow these steps:

  1. Simultaneously press and hold the Power button and Home button until the device shuts down and reboots. 
  2. When the Apple logo appears, release both the Power and Home buttons.

To force restart an iPhone or iPad without a physical Home button, refer to these steps instead:

  1. Quickly press and release the Volume Up button.
  2. Quickly press and release the Volume Down button.
  3. Then, press and hold the Power button until the Apple logo appears.

A forced restart is a simulated battery removal procedure to abruptly shut down and reboot the operating system. This is the alternative procedure to a soft reset for stuck or unresponsive devices. Similar to a soft reset, minor software crashes and system errors caused by recent updates are remedied in the process.

Second solution: Install pending app updates.

If it’s not the operating system, rogue apps can also trigger the device to experience random unexpected reboots. Apps that are outdated are usually the main culprits. To clear this out, follow these steps to manually check for and install pending app updates on your iOS device:

  1. From the Home screen, tap App Store to open the Apple Store application.
  2. Next, scroll down to the bottom of the screen then tap Updates. A list of apps with pending updates will then show up on the next screen.
  3. Tap the Update button next to the name of an app to install individual app updates.
  4. Tap the Update All button on the upper-right side of the screen to update multiple apps at once. This option is only available if multiple app updates are available.

Allow all your apps to finish updating and once they’re done, reboot your iPhone to apply the recent app changes and to clear memory and app caches.

Third solution: Free up memory space.

As explained earlier, performance issues like symptoms of random crashes can also be attributed to insufficient memory on the device. Usually, you will get to see a storage full alert along with the options to free up space. This is very possible, especially if you’re fond of downloading huge apps and multimedia files to your device. After the update, the memory space might have shrunk even more. As a result, performance issues arise. To fix the problem, manage memory storage of your iOS device. Here’s how to get started:

  1. From the Home screen, tap Settings.
  2. Select General.
  3. Tap [Device Name] Storage.

View the available storage to gauge whether or not the memory space is sufficient. If the available memory is less than a gigabyte, then that’s an indication that the device is running low on storage. In that case, you’ll need to free up some space by deleting old and unwanted contents. You can also move some of your important files to iCloud or iTunes drive.

Fourth solution: Reset all settings.

Resorting to software resets is necessary if the problem continues after performing prior methods. If the recent iOS update overrides your settings and these overrides resulted in some system conflicts, then they must be rectified. To clear this out, follow these steps to reset all settings on your iPhone or iPad:

  1. Tap Settings from your Home screen.
  2. Tap General.
  3. Scroll down and tap on Reset.
  4. Choose Reset all settings from the given options.
  5. Enter your passcode when asked to proceed.
  6. Finally, tap the option to confirm all settings reset.

This reset erases all customized settings including invalid or incorrect configurations that caused conflicts with the iOS 13 update settings overrides. After the reset, you will need to re-enable necessary features including Wi-Fi and Bluetooth features so you can use them again.

Fifth solution: Erase and restore factory default settings.

A full system reset is usually needed if your iPad or iPhone continues to reboot when idle. There might be some complex system bugs that need to be wiped out for the problem to be totally resolved. But before you proceed, be sure to back up all your important files because they’ll also be erased in the process. Once you’re all set, follow these steps to factory reset your iPad or iPhone through settings:

  1. From the Home screen, tap on Settings.
  2. Tap General.
  3. Tap Reset.
  4. Select the option to Erase all content and settings.
  5. Enter your passcode to proceed.
  6. Tap the option to confirm full system reset or factory reset.

You can also use iTunes on a computer to manually erase and restore factory default settings on your iPhone or iPad. This is usually needed if your iOS device isn’t working stable.

Last resort: DFU mode restore.

If all else failed to fix the problem and your iPad or iPhone continues to reboot when idle, then your last option is a DFU mode restore. Putting your device in DFU state allows it to become accessible through iTunes even when the operating system or boot loader is corrupted or not working.

To enter DFU mode on an iPhone 8, 8 Plus and later models, as well as later iPads without a physical Home button, simply follow these steps:

  1. Connect your iOS device to the computer using the original USB cable.
  2. Open iTunes on your computer.
  3. Quick-press and release the Volume Up button.
  4. Then quick-press and release the Volume Down button.
  5. Now, press and hold the Power button until the iPad screen turns black. 
  6. After 10 seconds, press and hold the Volume Down button while still holding down the Power button for another 5 seconds.
  7. After 5 seconds, release the Power button but keep holding the Volume Down button for another 10 seconds.

To enter DFU mode on an iPhone 7 and 7 Plus models, follow these steps instead:

  1. Connect your iPhone to the computer via USB cable and then open iTunes.
  2. Then press and hold the Power/Side button until the power off slider appears. 
  3. Drag the slider to power off your device.
  4. After a few seconds, press and hold both the Power/Side button and Volume Down button for 10 seconds.
  5. Then release the Power/Side button but keep holding the Volume Down button for another 5 seconds.

If the screen remains black after releasing the remaining button, it’s an indication that you’ve already entered DFU mode and that your iPhone is already running in DFU mode. By then, iTunes will tell you that it has detected your iOS device and that is has to be restored. 

Just follow the onscreen commands to restore and repair your iPhone’s operating system in iTunes.

If you’re using an iPhone 6 or earlier models, entering DFU mode is done through these steps:

  1. Connect your iPhone to the computer via USB cable.
  2. Press and hold the Power/Side button for a few seconds until the power off slider appears.
  3. Drag the slider to turn off your device.
  4. After a few seconds, press and hold both the Power/Side button and Home button for 10 seconds.
  5. Then release the Power/Side button but keep holding down the Home button for another 5 seconds.

You will know when your iPhone has successfully entered DFU mode if the screen stays black after releasing the Home button. If the screen isn’t completely black or you see any logo on it, then that denotes it hasn’t entered DFU mode yet and so you’ll have to try again from the very first step.

Does your iPad, iPhone continue to reboot when idle?

In normal circumstances, performing the above procedures is usually enough to get rid of the symptoms unless you’re dealing with a stubborn iOS bug that requires a patch code. The same thing could happen if hardware damage is present on the device. With that said, you’ve got two more options left. You can either take your iPhone to the nearest Apple service for hardware assessments or escalate the problem to Apple Support. Performing the latter is necessary for the development of a dedicated fix patch, should the problem be caused by the unrectifiable iOS 13 bug. 

Alternatively, you can also resort to using iTunes alternatives. There are already a lot of third-party repair and recovery software available for various iOS devices. Among the most popular and widely used tools that are found effective in repairing fatal iOS errors are Dr. Fone, PhoneRescue for iOS, FonePaw iOS System recovery, Tenorshare ReiBoot and Joyoshare UltFix, to name some. You can download and install any of these tools on a compatible computer just like what you do with iTunes. Once you have your preferred software installed, connect your iPhone to the computer via USB cable/Lightning cable. Then launch the software to get started repairing major system issues inflicted by iOS 13 on your iPad or iPhone.
