Apple fixes iPhone 15 overheating issue with iOS update after reports of temps over 100 degrees

iPhone 15 models were overheating, with 57% of 9to5Mac readers experiencing the issue. Temperatures reached up to 107.1 degrees Fahrenheit.

Apple confirmed a bug in iOS 17 was partly to blame, along with demanding apps like Instagram and Uber.

Apple released iOS 17.0.3 to fix the overheating issue. Benchmarks showed no throttling of the A17 chip.

Thermal imaging cameras showed iPhone 15 models running much cooler after the update, around 90 degrees vs 100+ degrees before.

ZDNet testing visually confirmed the fix using the same thermal imaging camera to measure temperatures.
