What Causes the Overheating Issue on iPhone 15 Pro Models?
The overheating issue on iPhone 15 Pro models is caused by a bug in iOS 17 that affects the performance of the A17 Pro chip, which is the most powerful processor ever used in an iPhone. The A17 Pro chip is based on a new 3 nm manufacturing process that enables faster and more efficient performance but also generates more heat than previous chips.
Some third-party apps, such as Instagram and Uber, have also been overloading the A17 Pro chip, leading to problems with heat dissipation. Apple has been working with app developers to optimize their apps for the new chip and reduce the thermal impact.

How Does iOS 17.0.3 Fix the Overheating Issue on iPhone 15 Pro Models?
iOS 17.0.3 fixes the overheating issue on iPhone 15 Pro models by addressing the bug in iOS 17 that affects the A17 Pro chip. The update also patches a pair of security exploits that could allow an attacker to gain elevated privileges on your device or execute malicious code through WebRTC.
According to Apple, the update does not affect the performance or battery life of the A17 Pro chip, and the titanium and aluminium design of the iPhone 15 Pro models provides better heat dissipation than the stainless steel frames used in previous models.
