Apple has published an iOS 17 system update that includes a remedy to keep the iPhone 15 range from becoming too hot.
The accompanying patch notes state that iOS 17.0.3 “addresses an issue that may cause iPhone to run warmer than expected.”

The Cupertino, California-based business blamed a software flaw and other difficulties related to popular applications like Instagram and Uber for causing its recently announced iPhone 15 models to overheat and stir concerns about being too hot to handle.
“We have identified a few conditions that can cause iPhone to run warmer than expected,” Apple said in a brief statement to The Associated Press last week, following media stories detailing overheating issues on internet message boards.
It’s not uncommon for new iPhones to become uncomfortably heated during the first few days of usage or when being restored using backup data saved in the cloud – concerns that Apple already warns consumers about. The handsets may also grow hot while running programs that need a lot of processing power, including Apple video games and augmented reality technologies, but the heating concerns with the iPhone 15 models have gone beyond those standard scenarios.
Apple stated in its statement that the issue is unrelated to its new CPU or the titanium case that houses the high-end iPhone 15 Pro and iPhone 15 Pro Max.
Apple also refuted suggestions that the overheating issue in the new models was caused by a switch from its proprietary Lightning charging connector to the more commonly used USB-C socket, which let it to comply with a European regulators’ rule.
