iPhone 16 Pro Teardown: Metal Battery Shell and Improved Cooling Design

The YouTube channel RewaTechnology has released a detailed teardown video of the iPhone 16 Pro, revealing the internal design specifics of the new model. During the disassembly, engineers first accessed the device's interior by applying heat to the rear of the phone and separating the glass back cover. The first significant change was the battery, which, as previously rumored, featured a shiny steel casing with adhesive pads. This contributes to better heat dissipation compared to previous battery shells. The video notes that the metal battery shell is exclusive to the iPhone 16 Pro model.

The TrueDepth camera assembly's build closely resembles the iPhone 15 Pro, but its size is smaller due to a different cable arrangement. The rear camera assembly is larger, partly due to the bigger components of the telephoto camera. The motherboard used in the iPhone 16 Pro is also smaller than its predecessor, employing a new, denser layout. The new model's shield is larger, which may also aid in thermal performance.

The teardown also reveals that the iPhone 16 Pro's display has a larger physical size compared to its predecessor, but with thinner bezels and a smaller screen frame. The camera control button is a new design on the chassis, an inseparable component laser-welded to the housing. After removing all components, the new chassis layout becomes apparent. The new graphite-coated aluminum chassis structure further enhances heat dissipation and rigidity.

This teardown unveils multiple internal design refinements in the iPhone 16 Pro, particularly optimizations focused on cooling performance. The metal battery shell, denser motherboard layout, larger shield, and new chassis structure all contribute to keeping the new model at stable temperatures during high-load usage. These improvements will provide users with a smoother experience and extend the lifespan of the device.
