Highlights
- iPhone 15 Pro series faces overheating issues, especially when charging.
- Apple considers using titanium casing, raising heat dissipation concerns.
- Rumours suggest a graphene vapour chamber could cool future iPhone models.
- Apple’s exploration of advanced thermal management aims to enhance user experience.
Apple’s release of the iPhone 15 Pro and iPhone 15 Pro Max models hasn’t gone down as smoothly as the company would have liked.
As per reports, users have been vocal about the devices’ tendency to overheat, a problem initially so severe it drew comparisons to handling a freshly microwaved Hot Pocket.
This issue was particularly pronounced when running certain applications, such as Instagram and Uber, leading to an uncomfortable user experience and accelerated battery depletion.
Thankfully, the deployment of iOS 17.0.3 in early October addressed the primary bug causing this overheating, providing much-needed relief to users.
iPhone 15 Pro’s Titanium Casing Causing Heat
However, some owners of the iPhone 15 Pro series have continued to report excessive heat during use, particularly while charging.
Ming-Chi Kuo, usually the top dog when it comes to Apple news, has suggested that the choice of titanium for the handset’s casing could be exacerbating the issue, given the material’s inferior heat conductivity compared to steel.
In contrast, Samsung has proactively addressed similar concerns with its Galaxy S24 Ultra by significantly enlarging the vapour chamber (VC) by 92% compared to its predecessor, the Galaxy S23 Ultra.
The S24 Ultra also uses Titanium for its frame but the enhanced VC has offset most of the heating issues.
Looking at these issues, Apple’s response to ongoing thermal management challenges are likely evolve, with rumours suggesting that the company is finally incorporating a vapour chamber in future iPhone models.
Graphene Vapour Chamber on iPhone 16 Series?
Apple has reportedly been exploring the idea of VCs on iPhones since 2021.
For the uninitiated, a VC operates by absorbing internal heat and converting a contained liquid into gas, which then cools and recondenses, cycling back to cool the device’s processor effectively.
Graphene is renowned for its exceptional thermal conductivity and could represent a significant advance over the graphite pads currently employed, promising enhanced heat dissipation and potentially mitigating the overheating issues that have plagued earlier models.
Apart from, among the anticipated innovations, there are also reports emerging of a metal shell for the battery, which could offer improved thermal properties and a graphene layer attached to the processor.
As Apple continues to push the boundaries of smartphone technology, effective thermal management remains a critical consideration, both for user comfort and device performance.
The transition to materials like graphene could mark a significant step forward in addressing these challenges, ensuring that future iPhones can deliver the high-performance, user-friendly experience that customers expect.
