[Full Guide] 11 Ways to Fix iPhone Keeps Restarting

Part 1: Why does my iPhone keeps restarting?

Here usually two kinds of iPhone keep restarting issues.

• Case 1: iPhone restart intermittently: You can access your iPhone and use it for a while but restart after a few moments.
• Case 2: iPhone restart loop: The iPhone continuously restarts repeatedly and couldn’t get into the system at all. There could be plenty of reasons for the iPhone keeps restarting issue. This is a commonly faced problem in which the iPhone screen displays the Apple logo. Instead of booting the phone, it goes back into the same loop and restarts the device again.

Here are a few things that might be a reason why your iPhone keeps restarting itself from two aspects.

1. Bad update

This is one of the most common issues for the iPhone keeps restarting error. While updating your device to a new version of iOS, if the process gets halted in between, then it might result in a few issues. My iPhone keeps restarting whenever an update is halted in between, or the update goes wrong altogether. An unstable update of iOS can also result in this issue.

2. Malware attack

This usually happens with jailbroken devices. If you have performed a jailbreak on your device, you can install apps from other sources. Though, this comes with a few disadvantages as well and makes your device vulnerable to security threats. If you have installed an app from an unreliable source, it can result in the iPhone keeps restarting error.

3. Unstable driver

If any driver has become unstable after a prominent change in your phone, it can also put your phone in the reboot loop mode. The best way to overcome this is by updating your firmware.

4. Hardware issue

The chances of this are pretty bleak, but there are times when a malfunctioning hardware component also causes this problem. For instance, there could be a problem with your device’s Power key that might cause this error.

5. APP Problems

Apps don’t often cause the iPhone to keep restarting issue, but it can still happen. If you wrongly installed an app, your iPhone may keep restating itself.
