The heating problem on iPhone 15 is not because of the underlying hardware or Titanium frame, according to a statement Apple gave to Forbes. The Cupertino company blamed it on third-party apps and a software bug.

“Apple is actively working on graphene thermal system of iPhone 16 Series to solve the heating problem existing before,” said the leaker.

Current iPhone 15 models rely on what is called a vapor cooling system. Kosutami did not detail how the new cooling system on the iPhone 16 works but said Apple is also planning to use a metal shell on the battery of upcoming iPhones to further prevent heating.

If what the leaker says is true, the iPhone 16 might not heat as much as the iPhone 15 series. The new iPhones should be released in the fall of 2024.

You can expect all four models to be powered by the A18 Pro chip. Apple may also introduce an additional “capture button”.
