iPhone 15 Pro shows false “iPhone needs to cool down” warning on iOS 27.0.1

Hi! I have an iPhone 15 Pro running iOS 27.0.1. I’m experiencing a serious issue with a false temperature warning.

My iPhone is physically cold and not under heavy load, but it randomly shows the “iPhone needs to cool down” temperature . It can happen at completely random times, including during normal use.

The issue started after updating to iOS 27.0.1. I’ve seen other iPhone 15 Pro users reporting the same issue.

Could you please check if this is a known issue and escalate my case to the appropriate technical team? I’d also like to know whether Apple is currently working on a fix and if there is any estimated timeframe for it.

I’m really concerned because the warning makes the phone difficult to use even though it is not actually hot.

Apple is not participating on this user to user forums and therefore cannot escalate your issue. As volunteer on this community I can confirm that I see this issue happen to some people. Have you tried to force restart your iPhone to see if the issues persist ?

Press and quickly release the volume up button.
Press and quickly release the volume down button.
Press and hold the side button.
When the Apple logo appears, release the side button.

Apple Support has stated this is a bug in iOS 27.0.1. They are working on an update and it will be released soon.

A mi me está pasando lo mismo con el iPhone 15, mi condición de batería está al 100 y mi teléfono es nuevo 9 meses de uso, lo reinicie y nada.
