While anecdotal experiences suggested that some iPhone 15 review models were running slightly warmer than anticipated, Hiner took a more scientific approach. He employed a thermal camera to monitor the performance of his iPhone 15 Pro Max review unit during fast charging with a 35W charger. Before the update, the device reached a temperature of 107.1 degrees Fahrenheit (41.2 degrees Celsius). However, following the installation of iOS 17.0.3, the temperature peaked at a much more manageable 93.8 degrees Fahrenheit (34.3 degrees Celsius).
Thankfully, the measures taken by Apple to alleviate overheating concerns did not affect the phone’s performance. As a result, it appears that the initial overheating issue has been successfully addressed with this update.
