Despite Apple’s efforts to address the iPhone 15 Pro’s reported heating issues, some users continue to experience excessive warmth, even after iOS updates and device replacements.
Apple technicians have reportedly referred to the issue as “expected behavior,” but the company has not officially confirmed this stance. Users have noted that the phone can become warm even during light tasks like gaming or using the camera.
While some users have found success in resolving the issue through a complete erase and restore, indicating a potential software problem, others suspect that the shift to a titanium frame may be contributing to the heating issue due to its lower conductivity compared to steel and aluminum.
Looking ahead, Apple is rumored to be exploring a graphene thermal system for the iPhone 16 series, leveraging graphene’s exceptional heat dissipation properties. However, this material is more expensive and challenging to produce.
With the increasing performance demands on smartphones, cooling is becoming a critical consideration for manufacturers. Overheating may become more prevalent, necessitating innovative approaches to temperature management, especially under heavy loads.
We may witness the adoption of active cooling solutions, such as fans or larger vapor cooling chambers, in future smartphones to address these thermal challenges.
