Is anyone else experiencing the new iPhone 18 Pro getting unusually hot?? Only had the phone for 24 hours but it gets really hot, seemingly at random - meaning the camera isn't on or even a lot of apps open. at one point i felt it in my shirt pocket and there was only 1 app open on the phone. is this happening across the board or should I be opening a ticket with Apple.

Keep in mind when you a get new iPhone, for the first few days, the phone is working hard to index the millions upon millions of bytes of data from your previous iPhone. Give the phone a few days to finish its normal housekeeping, then see if there are any issues.

Hi, this sounds like an app that got stuck in a loop or is not optimized for iOS 27 or a corrupt cache for the app. What app(s) used all the battery capacity? Follow this path,

I have had my phone for a month now, no heat issues all that time. The phone started getting hot today, intermittently. By mid-afternoon the battery was at 39%, I charged it to 90%. At 9 p.m. battery level had dropped to 20%. So I had to charge twice today even though I was not using the phone intensively. I was able to do so because I was at home, but if this happens while out or travelling it would be a significant problem. It would be very easy for Apple to restrict background processes to only run while charging, in any case it should not lead to so much heat production. <Sarcastic comment about unwanted AI features here>
