Last Monday, Apple published iOS 17.0.3, which includes two major security upgrades and claimed to solve a widespread issue with iPhone 15 overheating. The update’s release notes just claim that it solves “an issue that may cause iPhone to run warmer than expected,” but real-world tests have proven that it significantly lowers temps.
According to ZDNet’s Jason Hiner’s tests, the upgrade reduces temperatures by up to 15 degrees at their warmest point. While evaluating the iPhone 15 Pro and Pro Max, Hiner encountered overheating and discovered that the Pro Max reached 107.1 degrees Fahrenheit (41.2 degrees Celsius) while charging. He also had heating problems while using the Halide camera app.
Hiner loaded the 17.0.3 update and charged the phones after Apple published it. The temperature reached a high of 93.8 degrees Fahrenheit (34.3 degrees Celsius) and ranged from 80 to 90 degrees Fahrenheit (26.7 to 32.2 degrees Celsius). Hiner also stated that the upgrade had no effect on phone performance.
Apple replied to many allegations of the iPhone 15 overheating by citing three probable causes: excessive activity when setting up a new iPhone, problems with recently updated apps, and an iOS 17 flaw. In addition to the iOS 17.0.3 update, Apple is collaborating with app developers to identify any possible performance concerns with the A17 Pro processor in the iPhone 15 Pro and Pro Max.
Install the iOS 17.0.3 update if you have a new iPhone 15 (it also includes essential security upgrades). If you haven’t purchased one yet and expect to do so soon, the update should be available for download when you set up the phone.
