The iPhone 15 Pro and iPhone 15 Pro Max aren't officially out yet, but some tech enthusiasts have already gotten their hands on them already. That said, there are also many complaints of the new iPhone Pros overheating but not everyone thinks the same.
It's very easy to point at the A17 Pro chipset as the culprit, but according to Apple analyst Ming-Chi Kuo, it's not that simple. In his blog post, he said the overheating issue was most likely caused by the thermal system design instead of the chipset. With the new titanium frame, lighter weight and reduced heat dissipation area, these could be the factors that affect thermal efficiency.
On the other hand, BGR also reported that the iPhone 15 Pro and iPhone 15 Pro Max don't have any extra cooling features. However, there are graphite sheets to move heat from the logic board to the back of the iPhone. According to Apple, the new titanium build is Grade 5 and is bonded to the aluminium frame which should help heat dissipation.
Apple has yet to make any announcement regarding the 50-50 overheating issues experienced by users. But Kuo said he thinks Apple will release a software update to address the issue. Moreover, it could impact the shipments and sales of the iPhone 15 Pros if it's not solved by then.
