Worried about why your iPhone keeps turning on and off repeatedly? Here’s an article dedicated to the causes behind and their fixes

Is your iPhone frequently restarting unexpectedly? This can be quite frustrating. Several factors might contribute to this issue, ranging from hardware to software malfunctions. For example, a faulty battery, software glitches, or even a malfunctioning power button could be the culprit.

Let’s take a closer look at each potential cause and explore solutions to address these problems effectively.

Why Does My iPhone Keep Restarting Itself?

This issue manifests in several patterns. Sometimes, the phone unexpectedly restarts on its own. Other times, it restarts and then shuts down, only to start up again, leading to an endless cycle. Below, I’ve outlined some of the most common reasons for this problem:

1. Software Related Issues

One of the most common reasons why iPhone keeps freezing and restarting is due to software issues. This can happen if the operating system has become corrupted or if there is a bug in one of the apps you have installed.

2. Hardware Issues

Another common reason why iPhone keeps turning on and off repeatedly is due to hardware issues. This can happen if there is a problem with the battery, such as if it has become swollen or damaged.

3. App Glitching

App glitching can also be a reason behind your iPhone turning on and off repeatedly. This happens when an app is not functioning properly and is causing your iPhone to crash.

4. Battery Health

Finally, battery health issues can also cause your iPhone to turn on and off repeatedly. If your iPhone’s battery is not holding a charge properly, it may cause your iPhone to shut down unexpectedly.
