Recent reports suggest that the upcoming iPhone 16 series will incorporate a new thermal design aimed at addressing hardware-level overheating issues. According to information shared by the Twitter user @KosutamiSan, Apple is actively working on a revamped heat sink and battery design to effectively dissipate heat. Unlike some Android counterparts, Apple only introduced an overheating solution in iPhones with the iPhone 14 series, which featured graphite pads.
Despite the inclusion of graphite pads, the iPhone 15 series encountered significant overheating problems. While Apple managed to alleviate the issue to a considerable extent with the release of iOS 17.0.3, the company is now focusing on a hardware-level solution for the iPhone 16 series. Let’s delve into the purported new thermal design and its anticipated benefits.
The Apple iPhone 16 Series is Expected to Feature a Graphene Heat Sink
Previously, users of the iPhone 15 Pro model reported severe overheating problems, even during basic tasks such as web browsing or scrolling through the Instagram feed. Apple acknowledged the issue, attributing it to improper iOS 17 optimization. The company addressed the problem by releasing iOS 17.0.3, which prominently featured the overheating fix in the changelog, effectively mitigating the issue. However, Apple seems to recognize the limitations of relying solely on software fixes for such concerns.
According to insider information from @Kosutami, Apple is actively developing an advanced thermal management system for the upcoming iPhone models. If the leaked information is accurate, the iPhone 16 series will incorporate an enhanced graphene heat sink, replacing the basic copper heat sink used in the iPhone 15 series. For those unfamiliar, graphene offers superior thermal conductivity compared to copper, promising more effective heat management for the iPhone 16 series.
To ensure a proactive approach in preventing a recurrence of the iPhone 15 Pro series overheating debacle, Apple is reportedly combining the graphene heat sink with a specialized metal bracket housing for the battery. This integration aims to enhance heat transfer and promote better cooling of the battery in case of overheating. It is advisable, however, to approach this information with a degree of caution.
Apple is actively working on graphene thermal system of iPhone 16 Series to solve the heating problem existing before. And the battery of Pro series would change to metal shell, for the same reason.
