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.
