- Several early adopters are reporting heating issues on the iPhone 15 series.
- These issues are during charging and, separately, during prolonged phone use.
- We can independently confirm these heating issues on our iPhone 15 Pro Max.
The iPhone 15 series is the hottest phone in the market and in more ways than one. Customers who pre-ordered their iPhone 15 in the launch week have now received their phone and have spent a few days settling into it. Several early users, including me, now report facing excessive heat on their phones, especially during charging and prolonged use.
Speaking from my personal experience, my iPhone 15 Pro Max running iOS 17.0.2 runs very hot in two scenarios. One is during charging with a 65W USB PD GaN charger (which I have used with previous iPhones, Android flagships, laptops, earbuds, and more). With this charger, my iPhone 15 Pro Max gets very hot, to the point of discomfort, when holding the phone without a case. When using it with a case, I can feel the heat through the case. Using a 15W USB PD charger eliminates this heat, but the charging is also slower than it already is.
