The iPhone 15 series was plagued by overheating issues acknowledged by Apple, which it blamed on poor software optimization in iOS 17. The problem has since been largely mitigated with the release of iOS 17.0.3, but it appears Cupertino may opt for a hardware solution in the near future. This year’s iPhone 16 series.

Based on a new rumor, Apple is actively considering replacing the iPhone 15’s copper heat sink with a graphene solution for the iPhone 16. Graphene offers superior thermal conductivity than copper and is expected to be a notable update on next year’s iPhones. The graphene heat sink would be paired with a new metal bracket housing for the battery to aid in better heat transfer and cooling. We should say that this is still an early rumor so, as usual, take it with a grain of salt.
