Highlights Apple releases iOS 17.0.3 to tackle overheating in the iPhone 15 series. iPhone 16 rumoured to feature a graphene-based thermal management system. New metal bracket design around the iPhone 16 battery for improved heat dissipation. Skepticism remains about the unconfirmed hardware changes in the upcoming iPhone 16. The iPhone 15 series encountered significant overheating problems shortly after its launch. This issue was not isolated to a specific model; it affected the entire range, including the iPhone 15, iPhone 15 Plus, and the Pro variants. Users reported extreme temperatures, with some devices becoming too hot to handle comfortably. Now Apple has finally released a software update, iOS 17.0.3, which is aimed at addressing these concerns by rectifying software bugs and enhancing app optimization to prevent overheating. Graphene-Based Cooling in iPhone 16 Apple Addresses iPhone 15 Overheating with Software Update But even before the software optimisations, Apple is actively working on a more permanent solution to the overheating issue for its next-generation iPhone 16. One of the key developments is the introduction of a graphene-based thermal management system. This new system is expected to be a significant upgrade from the current copper heat sink technology used in the iPhone 15 series. The graphene-based system promises to be more efficient in dispersing heat, potentially resolving the overheating problem more effectively. Enhanced Heat Dissipation with New Battery Design New Design Element in the iPhone 16 In addition to the graphene cooling system, Apple is rumoured to incorporate a new design element in the iPhone 16 – a metal bracket surrounding the battery. This change is speculated to improve heat dissipation, particularly for the device's central processing unit and the battery. By redesigning the physical structure around these components, Apple aims to ensure better thermal management, contributing to the overall performance and user experience. Caution and Anticipation iPhone 16 New Features While these developments are promising, it is essential to approach them with a degree of caution. The information about the iPhone 16's new features comes from leaks and has not been officially confirmed by Apple. Given that the iPhone 15 series was only recently released, the details regarding the iPhone 16 are still emerging. As the expected launch date in the latter half of 2024 approaches, more concrete information about the device and its features is anticipated to become available. iPhone 15 Key Specs GENERAL Country
