iPhone 15 Pro Overheating Likely Caused by Thermal Design, Not 3nm Chip

  • iPhone 15 Pro overheating likely due to thermal design compromises, not 3nm chip manufacturing process according to analyst Ming-Chi Kuo.

  • Reduced heat dissipation area and titanium frame negatively impact thermal efficiency.

  • Software updates may help but will be limited without reducing processor performance.

  • Shipments could be impacted over iPhone 15 Pro lifecycle if issues not properly addressed.

  • Tests show processor throttling when overheating during benchmarks and extreme use cases.

Apple is facing significant production issues with the camera sensors and titanium chassis for the iPhone 15 models, which may impact availability, according to analyst Ming-Chi Kuo. Additionally, the iPhone 15 Pro Max is experiencing delays in manufacturing, potentially causing problems for early upgraders.
The iPhone 15 Pro models are expected to be 10% lighter than the iPhone 14 Pro models, thanks to a lightweight titanium frame, potentially making it the lightest Pro model since the iPhone XS or iPhone 11 Pro.
The iPhone 15 Pro Max's A17 Pro chipset, built on TSMC's 3nm node, offers superior single-core performance and improved graphics capabilities compared to the A16 chipset in the iPhone 14 Pro Max, with higher clock speeds and enhanced ray-tracing and HDR calculation abilities.
The iPhone 15 is a significant upgrade from previous non-Pro models, featuring a more powerful chipset, a 48MP primary camera, the Dynamic Island feature, and improved HDR, making it the best non-Pro iPhone upgrade in years.
The iPhone 15 Pro Max experiences substantial thermal throttling and overheating during intensive tasks like gaming, potentially indicating insufficient thermal headroom or similarities between the A17 Pro and A16 Bionic chips.
Apple is experiencing strong demand for various models of the iPhone 15, not just the higher-end Pro versions, according to J.P. Morgan analyst.
Some users of the iPhone 15 are experiencing overheating issues while charging, with reports of the device becoming "almost too hot to touch."
Apple has acknowledged that the iPhone 15 and 15 Pro can get uncomfortably hot due to background activity, an iOS 17 bug, and third-party apps, but a software update and fixes are coming to address the issue.
The iPhone 15 series experienced heating issues, the iPhone 14 Pro had a camera rattling problem, the iPhone 4 had antenna issues, Apple deliberately slowed down older iPhones without informing users, and the iPhone 6 series suffered from the Bendgate controversy.
The iPhone 15 has outdated and underwhelming specs, including a lack of an always-on display, low refresh rate, and the use of a previous generation chipset, making it difficult to recommend over other comparable Android flagship devices or even the iPhone 14 Pro.
iPhone 15 Pro users are reporting continued issues with overheating despite updating to iOS 17.0.3, experiencing problems during phone calls, gaming, and other activities, indicating potential quality control problems with certain batches of the device.
Apple's adoption of TSMC's A17 Pro chip for its iPhone 15 Pro models is expected to contribute 4-6% of TSMC's total sales this year, and next year, Apple is predicted to use TSMC's N3E chip tech for its iPhone 16 Pro models, with five other companies expected to do the same for their advanced chips.
Apple released the iOS 17.0.3 update to fix the iPhone 15 Pro overheating issues, however, some users are still complaining that the device gets hotter than its predecessors.
The iPhone 15 Pro Max is reportedly experiencing screen burn-in issues, adding to a growing list of problems for Apple, and affected users have posted about the problem on Reddit.
The iPhone 15 Pro Max is experiencing screen burn-in issues, adding to a growing list of problems for Apple.
The iPhone 15 Pro Max is facing display burn-in issues, with users reporting the ghosting effect on their devices even without leaving static images onscreen for extended periods, suggesting a quality control problem with Apple's newest model.
The iPhone 15 Pro and Pro Max have faced controversies such as overheating and case wear, but overall deliver impressive improvements in cameras, charging speeds, battery life, and performance.
