To help you better sort out and solve the iPhone turning on and off repeatedly issue, we will list 7 ways to solve the problem and the detailed steps for each. We hope that our guide will be helpful to you.

Part 1. Why Your iPhone Turns On and Off Repeatedly

First, let's analyze the reasons for this problem in detail from several aspects. Only when the root cause of the problem is found can the problem be solved more efficiently.

Update Failure

This is one of the most common culprits that cause the iPhone to switch on and off constantly. If your iPhone recently updated its system, but the update progress was interrupted, or the update failed, your iPhone may be stuck in a constant on/off cycle.

Hardware Issues

This is probably the most intuitive reason. If your iPhone's hardware components malfunction, such as a broken power button or an out-of-control screen, your device will receive the wrong commands and thus repeat the on/off action.

Malware Attacks

If you've ever jailbroken your iPhone, your phone may be more susceptible to malware attacks. The malware may mess up your system, thus causing the iPhone to switch on and off repeatedly.

Unstable Driver

If you have recently made some changes to the system of your device, this may cause the driver to malfunction. And reboot loops will happen on your device. This also means you need to update your iPhone’s firmware.
