IPhone X is actually disassembled. A stacked motherboard and two battery modules are used in the compact body.

When iPhone X went on the market, iFixit quickly dismantled the real machine. It can be confirmed that the dual lenses originally arranged horizontally in iPhone 7 Plus and iPhone 8 Plus are changed to vertical configuration because of the original deep camera module with Face ID function. At the same time, it can be confirmed that Apple has adopted a stacked motherboard and a two-piece battery module in the iPhone X, so as to place components and sufficient battery power in a smaller body.

Judging from the dismantling results of iFixit website, Apple did adopt a stacked motherboard design in iPhone X as rumored, which enabled many components to be placed in a relatively small body smoothly, and at the same time, the originally long battery module was split into two pieces according to the requirements and arranged in an L-shape, thus effectively utilizing the internal space.

Judging from the arrangement of the original deep camera module, it is not difficult to understand why the dual lenses originally arranged horizontally in the iPhone 7 Plus and iPhone 8 Plus will be changed to vertical configuration, because if they are arranged horizontally, they will inevitably get stuck in the original deep camera module component located at the top and center of the screen.

In addition, iFixit website also aims at the operation of Face ID, scans the face details through infrared camera and extracts specific features, so that the system can quickly judge whether the face shot by the lens is consistent with the original login information through these comparison information, thus achieving the purpose of identity verification. As for the technical principle of Face ID, it originated from 20 13' s acquisition of Apple for $360 million to help Microsoft build Kinect somatosensory camera PrimeSense.
