Apple is working on graphene cooling for iPhone 16 series

The iPhone 15 overheating issues have been largely resolved by iOS 17.0.3. With the Apple iPhone 16, the hardware is supposed to cool.

The Apple iPhone 15 series appeared on the Internet just a few weeks after its launch in September with less encouraging news. The new Apple phones were plagued by overheating problems, which Apple was forced to acknowledge fairly quickly. This shouldn’t happen again with the Apple iPhone 16.

The reason for the intense heat development was that the software was not perfectly tailored to the new models. iOS 17 was just as new as the iPhone 15 phones. In the iPhone 15 Pro and 15 Pro Max, Apple’s new flagships also had to contend with completely different thermal challenges thanks to the new titanium housings. Apple has now largely resolved the problem with the release of iOS 17.0.3. But it looks like Cupertino will opt for a hardware solution instead for next year’s Apple iPhone 16 series.

According to a new rumor, Apple is now considering replacing the iPhone 15’s copper heatsink in the iPhone 16 with a graphene solution. Graphene offers better thermal conductivity compared to copper. The material is likely to be a noticeable upgrade in next year’s iPhones. Apple would combine the graphene heatsink with a new metal casing for the battery for better heat conduction and cooling. So far, however, these are still early rumors. The current models have only been on the market for two months. Therefore, as usual, you should treat the report with caution.
