There are several reports that the iPhone 15 Pro will be warmer than expected. Apple already addressed the problem in September Last year it was claimed that a possible cause was due to third-party apps, and a supposed fix was released in iOS 17.1.
Despite several iOS updates with up-to-date phones running version 17.3 and 17.4 on the way, some users are still reporting iPhone 15 Pro And ProMax heat problems.
According to Notebook controlThe issues with the warmer iPhone 15 Pro are being referred to internally by Apple engineers as “expected behavior,” although Apple has not confirmed this.
Some users also report that the phone heats up when the device is not performing demanding tasks. Reddit user Meghrathod reported that after taking his iPhone to the Apple Store, he was told that unless he received a temperature alert, the phone was fine to use and passed all diagnostic tests. However, other Reddit users felt that light gaming and simply using the camera should not cause the phone to become uncomfortably warm.
Others inside the wire confirmed that their iPhone 15 Pros and Pro Max models were still extremely hot. One user said they thought they had received a bad device so they exchanged it, but the same thing happened with the replacement. Some claim to have fixed the problem by completely erasing it and then restoring it, which could point to a simple software issue rather than a flaw in the iPhone 15 Pro’s design.
An user, Richard1864, contradicted the group, saying that using 5G and gaming that causes a phone to heat up is normal behavior, as 5G mobile data is power intensive, many games are demanding on both the CPU and GPU, and all Android and iOS phones doing this. However, according to many in the thread, the iPhone 15 Pro appears to run slightly warmer than previous models.
Some suspect that the move to a titanium frame, while more durable, could worsen the problem, as titanium is less conductive and can dissipate less heat than the steel and aluminum found on previous iPhone models.
Graphene is the coolest
Apple is actively working on the graphene thermal system of the iPhone 16 series to solve the previously existing heating problem. And the Pro series battery would change to a metal shell for the same reason.November 16, 2023
Apple could try to address this in the iPhone 16 series, as a user on X (formerly Twitter) @KosutamiSan claims that Apple is working on a graphene thermal system for the iPhone 16 to solve the alleged heating problem. Graphene could work because the material disperses heat effectively and is stronger than steel, but it is more expensive and difficult to produce.
With the annual performance improvements of phones, cooling could become a major focus for future smartphones. Overheating may become an increasingly common problem as manufacturers must come up with new ways to maintain the temperature of devices, especially under heavy loads. Our phones may be quickly approaching the limits of what current cooling technology can handle.
We may see more phones with active cooling, such as the fans in the Redmagic 9 Pro or larger vapor cooling chambers such as in the Samsung Galaxy S24Ultra and OnePlus12.
