Following the recent launch of the iPhone 15 Pro on Friday, a notable influx of reports highlighting overheating concerns have emerged. In a recently published statement on Tuesday, the esteemed analyst, Ming-Chi Kuo, asserts that these thermal challenges do not stem from the cutting-edge 3nm A17 Pro chip, but instead, they are attributed to “compromises made in the thermal system.” 

The iPhone 15 Pro boasts the groundbreaking A17 Pro chip, marking a collaboration between Apple and TSMC and serving as their inaugural foray into the realm of 3nm processors. This development naturally led to the conjecture that the adoption of this new 3Nm technology was the root cause of the overheating predicaments.  

Nevertheless, Kuo refutes this assumption, contending that the issues arise from adjustments Apple implemented to accommodate the transition to titanium components, aimed at rendering the iPhone 15 Pro models lighter than their predecessors. 


Kuo expounds in his statement: “My survey indicates that the iPhone 15 Pro series overheating issues are unrelated to TSMC’s advanced 3nm node. The primary cause is more likely the compromises made in the thermal system design to achieve a lighter weight, such as the reduced heat dissipation area and the use of a titanium frame, which negatively impacts thermal efficiency.” 

Kuo prognosticates that Apple possesses the capacity to rectify these issues through software updates. Nonetheless, he introduces a caveat, indicating that any substantial enhancements might necessitate a compromise in chip performance: 

“It’s expected that Apple will address this through software updates, but improvements may be limited unless Apple lowers processor performance. If Apple does not properly address this issue, it could negatively impact shipments over the product life cycle of the iPhone 15 Pro series.”
