Apple recently took the wraps off its iPhone 15 series at its Fall event. The top flagship models reported overheating issues soon after, and several reports hinted that it could be due to its Titanium chassis. However, Apple quickly acknowledged and said the reason is the lack of software optimization in iOS 17. Apple largely fixed the overheating issue with the iOS 17.0.3 update. The iPhone 15 series has already arrived in many hands, and it’s too late for the company to recall devices and replace them with new ones. However, the Cupertino company is looking for more ways in the upcoming iPhone 16 series, including using a graphene solution.

The Apple iPhone 16 series could use a graphene solution

Apple is reportedly working on replacing the copper heat sink with a graphene solution on the iPhone 16 series. This comes from reliable leaker @KosutamiSan who added that Apple will also change the iPhone 16 Pro series’ battery to a metal shell for the same reason.

Graphene’s exceptional thermal conductivity would significantly enhance heat dissipation capabilities compared to currently used copper heat sinks. Apple Insider says that it is 10 times more effective than copper. Additionally, a new metal battery housing is rumored to complement the graphene heat sink. It will further improve heat transfer and cooling efficiency.

The iPhone 16 could be pricier than its predecessors

If reports of Apple using Graphene come true, a price hike could also be on the cards. Graphene costs more than copper to implement, and the placement may require a product re-design as well. This also aligns with previous reports of the iPhone 16 being significantly more expensive.

Notably, Apple has actively worked on finding solutions to fixing overheating in iPhones. For example, Apple patented a heat dissipater made of graphene in 2016. Moreover, the company reportedly has also been working on liquid cooling in iPhones.

While these reports remain unconfirmed, they hint at Apple’s commitment to optimizing thermal performance in future iPhone iterations. While @KosutamiSen has quite a history of providing reliable leaks, it’s too early to digest leaks. This news should be taken as a pinch of salt.
