Owners of the iPhone 15 are likely to seek the latest iOS update, iOS 17.0.3, which aims to address a widespread issue of the new iPhones overheating. Apple’s official statement regarding the update is that it resolves “an issue that may cause iPhone to run warmer than expected” and includes two critical security updates. Testing conducted by ZDNet’s Jason Hiner reveals that the update effectively reduces the temperature of the iPhone 15 Pro and iPhone 15 Pro Max by as much as 15 degrees during peak performance.

While anecdotal reports suggested that iPhone 15 review models experienced minor overheating, Hiner used a thermal camera to record a temperature of 107.1 degrees Fahrenheit (41.2 degrees Celsius) for his iPhone 15 Pro Max review unit during fast charging with a 35W charger. However, after applying the iOS 17.0.3 update, the temperature peaked at 93.8 degrees Fahrenheit (34.3 degrees Celsius). Importantly, this update did not impact the phone’s performance, indicating that it successfully addresses the initial overheating problem.

It is advisable to keep your smartphone up-to-date by installing the latest software updates, particularly when they are part of the official release. Typically, these updates include fixes, security enhancements, and performance optimizations rather than introducing significant new features that may have unforeseen consequences. To ensure timely updates, it is recommended to configure your iPhone to receive automatic updates. If you encounter any update notifications, it is best to install them promptly.

Conversely, beta versions of iOS or Android operating systems may not provide the same level of stability and security as official releases, making them less suitable for primary smartphone use. For automatic updates on iOS, the feature is usually enabled by default. However, if your device is not promptly receiving updates, navigate to the Settings app, locate the “General” section, and access “Software Update” to check for and install the latest updates. If your device is operating on an older iOS version, you will also receive prompts to upgrade to the latest release.
