An iPhone turning continuously on or off is a serious issue. Off late, many iPhone users have reported that their phone automatically turns on or off.
Sometimes, this issue might be due to a firmware problem (which only the Apple service center can fix), and in some cases, we can fix this issue with simple solutions listed in this article.
Common Reasons Why iPhone Keeps Restarting
Instead of booting the phone normally, if your iPhone keeps restarting time and again, displaying the Apple logo, then it might be due to the following reasons:
Malware attacks only happen with Jailbroken iPhones. These iPhones can install apps from any third-party source, which makes the device vulnerable to many threats. In case you have installed any apps from third-party websites, we recommend you delete them and see if the iPhone still restarts.
If you were updating your iPhone’s OS but failed halfway, you might see the restarting issue popping up.
It is very rare to have a hardware issue on an iPhone. If your iPhone’s power button is not functioning properly, it might also lead to a continuous restart.
If you have updated the iPhone recently, you might see some drivers not functioning properly. This can only be fixed with a firmware update.
