Disassembly of the iPhone 16 Pro smartphone confirmed the metal wrapping of the battery and improved cooling

Disassembly is an inevitable part of an iPhone launch, and the iPhone 16 generation is no exception. Shortly after its release, the iPhone 16 Pro was disassembled and examined internally, which revealed Apple's design changes.

Rewa Technology's teardown posted on YouTube includes a fairly standard teardown of the iPhone 16 Pro. After heating the rear wall and separating the glass back, the engineer gained access to the internal components as usual.

The first change to notice is the battery, which, as expected, has a shiny steel body attached with adhesive pads. This differs from previous battery cases, which may contribute to improved heat dissipation compared to previous generations.

Interesting is the fact that the video notes that the metal battery case is limited to the model only iPhone 16 Pro.

The TrueDepth camera module is similar in design to the iPhone 15 Pro version, except that it is smaller due to a different cable arrangement. The rear camera module is larger, partly due to larger elements for the telephoto lens.

The iPhone 16 Pro motherboard is also smaller than the previous model, with a new and tighter arrangement of components. The protective cover on the new model is larger, which may help with heat dissipation.

The display is physically larger than the old model, but also has thinner bezels and a smaller screen bezel. The camera control button, new to the case, is a stationary element laser-welded to the chassis.

With all components removed, a new chassis layout is revealed. A new graphite aluminum substructure, which again can help with thermal performance as well as increased stiffness.
