Overview
Shortly after launch, Apple officially acknowledged that the iPhone 15 Pro and 15 Pro Max experienced abnormal overheating, attributing the issue to a combination of iOS bugs, third-party app coding issues (particularly Instagram and Uber), and the titanium chassis offering less heat dissipation than previous stainless steel designs. While iOS 17.0.3 resolved most software-related heat problems, some units continue to overheat due to underlying hardware faults.
Common Causes
- iOS software bug in early 17.x releases causing the A17 Pro chip to run at elevated frequencies unnecessarily
- Third-party apps not optimised for the A17 Pro chip creating excessive CPU load
- Titanium frame providing less thermal mass than prior stainless steel chassis, allowing heat to build faster
- Battery fault or swollen cell causing the device to generate excess internal heat
- Logic board thermal paste degradation reducing heat transfer from the SoC
Signs & Symptoms
- Device feels uncomfortably hot on the back and edges during normal use or charging
- iOS displays a temperature warning and temporarily disables charging to protect the battery
- Performance throttling — apps feel slower than expected due to thermal management kicking in
- Battery percentage drops rapidly during periods of high heat
Should You Try DIY?
Attempting to open the iPhone 15 Pro to address thermal issues can damage the titanium frame, the rear glass, and the IP68 sealing gaskets. This is a precision repair requiring trained technicians and proper equipment.
Professional Solution
iTech Repairs first verifies the iOS version and rules out software-related causes before conducting a full hardware diagnostic on overheating iPhone 15 Pro units. Where a battery fault is identified, we replace it with a quality cell. Logic board thermal issues are addressed with our micro-soldering capability. All repairs include a full thermal test cycle before return.
