Many iPhone users have reported that their iPhone keeps freezing and restarting intermittently for a few minutes, restarts on its own, or occasionally under certain scenarios. This is a software issue in iOS that can pop up for various reasons. So, this article will tell you how to fix iPhone keeps freezing and restarting issue in details.

Part 1: Why Does My iPhone Keep Freezing and Restarting

You’ll be curious to know why does my iPhone keep freezing and restarting, even though it’s brand new. There can be multiple factors playing behind it. However, most of them can be software related that can cause an iPhone to keep freezing or restarting. Here are the common reasons for the ”iPhone keeps freezing and restarting” issue:

1. Bugs in Software Updates.

One of the common reasons for “iPhone keeps freezing and restarting” is the earlier software updates released for beta users. Apple warns users that these updates may cause unexpected errors and glitches, disrupting the user experience.

However, stable updates can also cause issues like these. The iOS 16 is a recent example of it which caused battery drain issues for some models.

2. 3rd Party Apps.

Installing the 3rd party apps from the unofficial channels can cause compatibility issues in iOS, which may disrupt the overall device performances and eventually cause freezing and restarting issues. 3rd party apps can contain malware or viruses that can cause severe software issues.

3. Insufficient Storage.

If you’ve fully loaded your iPhone’s storage, it’ll likely struggle to perform basic operations and become sluggish. For optimum performance, ensure there’s some storage left for the OS to save temporary files and be operative.

4. Jailbreak.

Jailbreaking your iPhone means uplifting the restrictions on the device’s OS that Apple has imposed. Doing so will enable you to customize the system and install unofficial apps, which can also be a culprit for “iPhone keeps freezing and restarting”.
