The iPhone 17 lineup is shaping up to be Apple's most ambitious upgrade in years, and according to industry sources, the company is finally addressing its long-standing thermal management issue. The iPhone 15 Pro models adhered to overheating issues, and there was quite a bit of a ruckus. While the company improved the thermals with the iPhone 16 lineup, it still gets plenty hot under heavy load, especially gaming. It is now being reported that Apple plans to incorporate a vapor chamber heatsink across the entire iPhone 17 lineup.
All iPhone 17 models will get a vapor chamber cooling solution, while the bigger 'Pro Max' will also rock graphite sheet for even better thermal management
Apple's implementation of a proper thermal management solution in its iPhone lineup has been a sore spot, considering how Android competitors have adopted vapor chamber cooling, even in the budget models. Apple's last year's iPhone 15 Pro models featured an A17 Pro chip, which brought thermal challenges to the mix and highlighted the need for a better cooling solution. Overheating caused the chip's performance to be throttled and hampered, which negates the entire purpose of an upgraded SoC.
According to sources familiar with the matter, the company is aiming higher for the iPhone 17 lineup, as the devices are reported to feature a vapor chamber cooling system (via MyDrivers). The bigger iPhone 17 Pro Max, on the flip side, is reported to feature a vapor chamber and graphite sheet cooling combination, which will set a new thermal performance and durability standard.
The company's new thermal solution will allow the A19 Pro chip to shine when it comes to performance, and it could be one of the tricks the company would have set in place to showcase the chip's capabilities. The A19 Pro chip will be based on TSMC's 3nm architecture, and it would only bring minimal gains, but conjoined with an efficient heat-dissipating solution, the jump in performance could be significant.
The report also claims that all iPhone 17 models will feature higher refresh rate displays, a feature which was only limited to the 'Pro' models. However, it remains to be seen if the company will use 90Hz panels for the standard models or upgrade them to 120Hz. Apple has been very reluctant to upgrade the display specifications of the standard models, and this year could be a big one for the company and its customers. Moreover, a higher refresh rate panel could also allow the base models to feature an Always-On display, but there have been no details on the matter so far. Take note that the iPhone 17 launch is still months away, and we will hear more details on the new thermal solution and the higher refresh rate, so be sure to stick around.
