If you're rocking an iPhone 15, it's probably a good idea to update to the latest version of iOS swiftly. Apple has released a fix for the overheating issues that have plagued its latest batch of iPhones. The company says that iOS 17.0.3 "provides important bug fixes, security updates and addresses an issue that may cause iPhone to run warmer than expected." An iPadOS 17 update is also available.
Apple partially blamed the overheating issue on an iOS 17 bug. It noted that there were also "some recent updates to third-party apps that are causing them to overload the system." The company has been working with the developers of those apps (which included Uber, Instagram and Asphalt 9) to resolve the problem.
Your iPhone may be configured to update to the latest version of iOS automatically during downtime when it's charging. You can also update your device manually, by going to Settings > General > About > Software Update on your iPhone. If iOS 17.0.3 is available to you (Apple rolls out updates gradually), you'll be able to install it right away and hopefully keep your iPhone from getting too toasty.
