On Wednesday, Apple rolled out the latest update for iOS 17.0.3, which addresses a known issue that could result in iPhones running at a higher temperature than usual. ZDNet’s testing has confirmed that the update successfully resolves this issue.
Jason Hiner from ZDNet encountered overheating problems with the iPhone 15 Pro and Pro Max. In order to measure the temperature, he utilized a thermal camera and discovered that the Pro Max reached a high of 107.1 degrees Fahrenheit (41.2 degrees Celsius) during fast charging. Additionally, he faced overheating concerns while using the Halide camera application.
After installing the 17.0.3 update, Hiner charged the phones and observed a peak temperature of 93.8 degrees Fahrenheit (34.3 degrees Celsius). The temperature then varied between 80 and 90 degrees Fahrenheit (26.7 and 32.2 degrees Celsius). Hiner also confirmed that the update did not impact the phones’ performance.
Apple addressed the widespread issue of the iPhone 15 overheating with three possible explanations: intense usage during initial setup, problems with recently updated apps, and a bug in iOS 17. As part of the iOS 17.0.3 update, Apple is collaborating with app developers to identify any potential performance concerns related to the A17 Pro chip in the iPhone 15 Pro and Pro Max.
If you recently purchased an iPhone 15, make sure to install the iOS 17.0.3 update, which includes crucial security updates. If you haven’t acquired one yet but plan to do so in the near future, the update will automatically appear for installation during the phone’s setup process.
