To prevent future iPhone 16s from overheating, Apple reportedly plans to make significant changes to the heat dissipation system. The Californian firm would in fact replace copper with graphene. We explain why.
Right after its launch, the iPhone 15 Pro was at the center of attention due to a serious overheating issue. Many users have revealed that smartphones emit a lot of heat when charging or after a few minutes of use. To correct the situation, Apple deployed a software patch, pointing out a bug in the iOS 17 operating system. Unfortunately, the update did not completely resolve the overheating of the iPhone 15 Pro. When the battery recharges, the camera is used for a long time or a demanding game is launched, the back of the iPhone quickly becomes hot.
In the future, Apple would rely on new technology to stem the overheating of its iPhones. From next year, the Cupertino giant would inaugurate a new system capable of dissipate heat emitted by the SoC and other components. This is what Kosutami, a renowned informant on his X account, says, whose comments are relayed by several specialized media, including Apple Insider.

Graphene to prevent overheating
According to the informant, “Apple is actively working on a graphene thermal system for the iPhone 16 series to solve the previously existing heating problem.” The company is apparently developing a heat dissipation system made with graphene for the iPhone 16. The use of this material is not trivial.
Graphene indeed benefits fromthermal conductivity ten times higher than that of copper, the metal currently used to dissipate heat in iPhone 15s. In short, graphene is better designed to dissipate heat than copper. This material, a very thin and strong form of carbon, would make it easier to dissipate heat through the device’s frame.
For the record, Apple is not the first manufacturer to rely on a form of carbon to prevent its phones from overheating. On the Pixel 8 and Pixel 8 Pro, Google actually uses graphite, that is to say several layers of graphene stacked on top of each other, to dissipate the heat emitted by the components. Furthermore, Apple reportedly plans to use a new metal case for the iPhone 16 Pro battery. Here again, this change should facilitate cooling of the terminal. We imagine that the box would make it possible to further evacuate the loss of energy, in the form of heat, from the accumulator.
As always, we invite you to take this rumor with a grain of salt, despite the good reputation and history of the source. Indeed, Apple is still free to make changes to the iPhone 16 between now and the launch of mass production, scheduled for the summer of 2024. Unless there are any surprises, the range will be announced during the month of September 2024 during a keynote.
