Great as the iPhone 15 line is, it’s not devoid of problems, and one early issue was a tendency for Apple's new phones to overheat in certain situations. In theory, these heat issues have now been fixed by an iOS 17 update, but Apple might make changes to the iPhone 16’s hardware to ensure there’s no danger of its next phones getting too hot to handle.
This is according to @KosutamiSan, who, posting on X (via Apple Insider), claims that Apple is “actively working” on a graphene thermal system for the iPhone 16 series. That presumably means all four expected models – the iPhone 16, the iPhone 16 Plus, the iPhone 16 Pro and the iPhone 16 Pro Max – would get this feature.
