While we’re fairly confident that Apple has overcome the overheating concerns raised at launch regarding the iPhone 15 Pro and iPhone 15 Pro Max, thermal concerns remain. We noticed that our iPhone 15 Pro Max continued to run warmer than we’ve experienced running other iPhones in the past. Indeed, this applies to almost all smartphones except the Pixel 8 Pro.
We recently went to an Apple Store as a private customer to have the iPhone 15 Pro Max tested for defects, and all tests performed by iPhone technicians came back clean. So we pushed the tech a little more about how unusually warm this generation of his Pro iPhone felt running compared to previous models he’s been using. Somewhat surprisingly, the engineer quietly admitted that Apple had advised engineers internally that this was “expected behavior.”
It’s not a huge problem in terms of the overheating issue that ruined the launch, but it still feels unusual for a device to heat up when you’re not doing anything other than carrying it around. As highlighted by Apple analyst Ming Chi-Kuo, titanium has a lower thermal conductivity than the steel frames that Apple previously used in the iPhone 14 Pro series, which may at least contribute to the thermal issue. There is a possibility that it has become.
Apple quickly admitted that a software bug in iOS 17 was responsible for the overheating issue at launch, and that certain third-party apps were also causing the chip to overload and heat up. However, while the initial patch to address this issue helped alleviate the issue, some users continued to experience the issue. Apple’s latest update, iOS 17.3, seems to have further helped alleviate the heat issues we experienced with the iPhone 15 Pro Max, but it didn’t stop it from running hotter than expected.
To highlight this, this article tested the iPhone 15 Pro Max, Galaxy S24 Ultra, iPhone 13 Pro, and ROG Phone 8 Pro, all idling at an ambient temperature of 26 degrees Celsius. The iPhone 15 Pro was 31.5 degrees Celsius, the Galaxy S24 Ultra was 29.3 degrees Celsius, the iPhone 13 Pro was 28.7 degrees Celsius, and the ROG Phone 8 Pro was only 26.8 degrees Celsius. The S24 Ultra is also made with a titanium frame, but with a 92% lower frame than the S23 Ultra to offset the effects of using titanium instead of the more conductive “aluminum armor” used in the S23 Ultra. % Equipped with a large vapor chamber. previous model.
As a phone made specifically for mobile gaming, it’s no surprise that the ROG runs noticeably cooler when idle. It uses an advanced combination of graphite sheets, fast-cooling conductors, boron nitride, and a vapor chamber followed by an additional graphite layer. Naturally, its sustained performance overwhelms even the iPhone and his S24 Ultra. But it’s also clear that the iPhone 15 Pro runs significantly warmer at idle than all the phones here, including the iPhone 13 Pro. But apparently Apple has a fix, but iPhone 15 Pro users won’t be able to benefit from it.
Apple was rumored to be testing an iPhone with a vapor chamber in 2021. However, we are yet to see Apple adopting such an approach, which would definitely help both the iPhone 15 Pro and iPhone 14 Pro series, which were also hit by the issue. There are no problems with heat, but only under intensive load, for example when playing games. In addition to a new steel outer coating for the iPhone 16 Pro’s battery, new rumors have also surfaced that Apple may do the following: Considering introducing the use of graphene Also as a thermal solution for iPhone 16 Pro.
Rutgers researchers have found that applying a layer of graphene deposited directly on silicon may be a more effective method than traditional solutions like graphite because of its much higher thermal conductivity. Highlighted research published in 2017. This helps draw heat away from the chip and dissipates it more effectively. Using this approach instead of a vapor chamber may be preferred by Apple as it does not add any additional weight to the iPhone 16 Pro. Apple is also said to be considering a steel case for the iPhone 16 Pro’s battery to further dissipate heat.
Whatever approach Apple takes to reduce heat on the iPhone 16 Pro series will no doubt be welcomed. Both the iPhone 14 Pro and iPhone 15 Pro are still experiencing heat issues, so the next iPhone Pro, expected to be released later this year, may finally eliminate this issue.
