As users only on this user to user only forum, we can't know why your iPhone is restarting. Have you been routinely updating your iPhone as updates have been released? iOS 18.5 was released today, so at a minimum, update to the latest release. Then after you update, Force Restart your iPhone, by following the directions in this link --> Force restart iPhone - Apple Support

Keep this procedure in your memory and use it after EVERY iOS update going forward.

As per my experience this is an hardware problem because i also faced the same on my 16 pro device and apple replaced the logic board for free, If the device is under warranty then you must go to apple service centre and get it diagnosed.

When iPhone 16 was released in September, there were reports of this, but as updates have been rolled out, we rarely see anyone saying it now. You didn't say whether you have been keeping up with updates?

Hello Justaamerican.

This is not normal with your phone. You should maybe check it with a local hardware store to see if it’s a hardware problem. You could also go to an Apple Store, but they are a little overpriced.

That is HORRIBLE advice. The phone is under warranty and if there is an issue with it, Apple will take care of it. What hardware store do you know which can diagnose or fix an iPhone? Where on earth did you get such an idea??
