iPhone 15 Pro had an overheating problem

Users complained of overheating iPhone 15 models shortly after release, which Apple fixed via software, but the iPhone 16 is rumored to have a hardware solution, too.

The iPhone 15 is already here and can’t get a hardware change mid-cycle, but X user @KosutamiSan says Apple is working on a solution for iPhone 16. The company could switch to a graphene heat sink and a metal battery case to promote better heat transfer.

The iPhone has no fan, so heat has to be dissipated through the device frame into the air using passive heat transfer. Heat sinks do precisely what the name implies, they remove heat from undesirable areas by having a more efficient thermal conduction value than the materials around it.

Kosutami is a known leaker that collects design validation test products and other such pre-production items. The leaker has a short history with accurate leaks like USB-C components for iPhone 15, but also some misses like with a supposed iPhone 15 Pro Thunderbolt cable. So, we’re rating this leak as possible.
