During the disassembly of the iPhone 16, iFixit found several small changes in the internal component placement, with the L-shaped logic board and one of the millimeter wave 5G antennas missing. The reason is the battery, which is larger than the iPhone 15 and uses a “hard steel case instead of a soft pouch.”
But the coolest feature is hidden under the battery. iFixit found that the batteries were held in place with a smart adhesive that “pulls apart when an electric current is passed through it.” This means the battery stays in place until a charge is applied, but it also means “a consistent, repeatable process that doesn’t rely on tricky and fragile adhesive strips.”
There is no tab to pull the battery. The battery is fixed with adhesive until 9V current flows. Like a car battery, an alligator clip was attached to the silver tab on the battery and another clip was attached to the ground screw next to the USB-C port. If you plug it into a power source and wait about a minute, the battery will magically detach from the case.
Afterwards, when the battery is replaced with a new one, the board layer is re-adhered to the case. You can see it in action in the following video.
