A teardown of the iPhone Duo reveals a highly complex internal architecture characterized by extreme component miniaturization and a multi-part hinge mechanism. The device features a split-battery design with a total capacity of 4,883 mAh, with the logic board and a vapor chamber cooling system positioned to accommodate the folding display. The internal selfie camera, located under the display, is a 4-megapixel sensor, while the main camera module is comparable to the iPhone 17 in sensor size and quality. The display itself consists of two layers, with the ultra-thin glass showing signs of shattering during the flex test. The device's repairability is extremely low due to the tight integration of components and the difficulty of accessing the internal hardware without damaging the screen or frame. The teardown highlights the significant engineering challenges involved in creating a foldable device of this size, with the vapor chamber cooling system being notably smaller than those found in the iPhone 18 Pro and Pro Max.
