The overheating iPhone 15 Pro problems were addressed with an iOS update, but Apple has a better solution for the upcoming iPhone 16 Pro.
Following the launch of the iPhone family, reports came in of new users experiencing handsets that ran hot. An iOS update mitigated the circumstances, but the basic equation of placing more demand on the processor and creating more heat that needs to be wicked away remains. While under more control than at launch, the iPhone 15 family still run hotter than your average iPhone.
Every generation of smartphones demands more performance than the last. The next generation of iPhones will be taking a larger-than-average step. As well as the usual expansion of capabilities, artificial intelligence will require more computing power. With the expectation that as much personal information and data as possible should be processed by AI routines locally, Apple will need to accommodate the demand for the presumptively-titled A18 chipset.
This means keeping everything cool will be a key part of the design. Android-powered gaming phones have developed several inventive solutions, including active cooling with fans and vents, oversized vapour chambers, and thermoelectric cooling using the Peltier Effect.
There’s renewed discussion about Apple introducing graphene for the next iPhone to help draw heat away from the chipset. Research has highlighted the benefits of using a boron nitride crystal substrate to increase the heat transfer capacity. This would be a thinner solution than a network of heat pipes and vapour chambers. All of these add bulk to a handset… a route that Apple’s designers have done their best to avoid.
Apple has already shown it is happy to introduce new materials to the iPhone package, with the titanium chassis’s appearance being a key selling point of the iPhone 15 Pro and 15 Pro Max.
Graphene could be the “one more thing” that unlocks the iPhone’s performance.
