Part 1. Why Does My iPhone Keep Restarting?
Collecting issues reported by iPhone users, we found that iPhone rebooting rises particularly in the iPhone 16, 15, and 14 series. Most users are wondering why their iPhone keeps restarting on its own.

We can roughly divide the reasons into external problems and internal problems. Some possible reasons are listed below for your reference.
Reason 1. Hardware Problems
The decreased battery capacity and lifespan of old batteries, or sensor errors that prevent sensing, can cause the iPhone to get stuck on the restart interface and become unusable.
Reason 2. Malware Attack
A third-party software that is not downloaded from the App Store may carry viruses that keep the iPhone restarting and shutting down.
Reason 3. System Bug
Although the chance is pretty low, previous versions of the system may have various unknown issues, which could also be one of the reasons for the iPhone randomly restarting.
Reason 4. Charge Cable and Port
Some users reported that the iPhone keeps restarting while charging. This is also related to a problematic charging cable and charger, in which case the iPhone can only be charged intermittently. Once the iPhone receives power and then it stops receiving power again, resulting in a continuous cycle of restarts.

Step 1. Enter Settings.
Step 2. Choose Privacy>Analytics & Improvements.
