Amidst various reports of overheating problems with the iPhone 15 Pro and Pro Max, Apple may already be considering a different cooling system for the iPhone 16.

According to the informant Kosutami on X, formerly known as Twitter, the iPhone 16, expected in 2024, may adopt a graphene cooling system to address the overheating issues faced by its predecessor, which currently uses copper for cooling.
Graphene is a form of carbon consisting of a single layer of atoms arranged in a hexagonal two-dimensional structure. It is known for its exceptional properties such as high electrical and thermal conductivity, mechanical strength, lightness, and transparency.
Apple may also incorporate a metal shell around the battery to mitigate internal heat. The temporary solution to the overheating issues in the current iPhone 15 models was a software update, but it does not seem to be definitive.
Apple is actively working on graphene thermal system of iPhone 16 Series to solve the heating problem existing before. And the battery of Pro series would change to metal shell, for the same reason.
