How to fix iPhone keeps restarting issue

Restarting your iPhone is important for many reasons but if your iPhone keeps restarting, here are some of the issues it may be facing.


Restarting your iPhone is important for many reasons. It is akin to refreshing the phone. By restarting the phone, redundant apps slowing it down are powered off. But there is a problem when the iPhone keeps restarting itself. Sometimes, your iPhone can enter an involuntary loop of constant restarting. This is an issue that can get infuriating and annoying; because, most times, your use of the phone is inhibited.

If you are experiencing the issue now and would like to know how to solve it, you don’t need to worry. By the end of this post, you would have found practical and workable solutions to dealing with the problem.

Before we go into the solutions for this problem, it is important to find out some causes. This way, you can further prevent it, to some extent, from happening again.

Causes of your iPhone constantly restarting

An iPhone that keeps restarting on its own is not a unique problem. Given the presence of some factors, it will happen. If an iPhone keeps restarting, here are some of the reasons causing the problem.

Hardware problem: This is one major cause of a restarting iPhone. Hardware problems refer to the physical components of the device that are faulty. For example, a pressed-in power button will cause the iPhone to keep restarting. Also, improper placement of the battery can cause it to lose and regain contact with the panel. Although this would just make your phone go off, it is still an example of a hardware problem.

Jailbreaking: Jailbreaking your iPhone helps you bypass some Apple restrictions, granting you unlimited access. However, it also reduces the available security on your device. This leaves your device open to potential attacks including malware, some of which may find their way into your device and cause malfunctioning. A constant restart can also be a product of a poorly done jailbreak.

Issues with updates: Updating your device can be met with some difficulties such as connectivity issues. These difficulties can result in an incomplete update or a bad update altogether. With a bad update, your device cannot function properly. This can result in constant restarting.


These are some of the causes. Generally speaking, the majority of the causes can fall under any of these categories. That said, here are some ways of dealing with the issue.

Fixing an iPhone that keeps restarting

Update your device

This should be the first step. Not only does it help you get the latest OS, but it also clears any issue that pertains to the OS you were using – issues like an incomplete update. It is advised that you first back up your files though.

Reset all settings

This will help where there is a possibility that a setting has opened your phone up to a biting attack. By resetting all settings, your device goes back to how it was originally set. This way, some security settings that might have been disabled are brought back. While you do not risk the loss of your data, you should back them up first. Just to be on the safer side.

This can be done by going to Settings – General Reset – Reset All Settings.

Connect your device to iTunes

Connecting your device to iTunes can be used to restore your most recent backup. This can help put secure and necessary data that are already backed up back into your phone. This way, unnecessary or interfering data is deleted. 

Your phone can still be connected to iTunes even if it is in recovery mode. All that is necessary is to connect the phone to a computer system with a stable USB cord. You should then launch iTunes on your system and go to the Summary Section. Click on “backups” and further click on “restore backups”. 

This is majorly useful in instances where the cause of constant restarting is a malware attack.
