iFixit has completed its teardown of the iPhone Duo and awarded it a provisional 5 out of 10 for repairability — the highest score the site has ever given a foldable. The dual batteries release cleanly and the outer display comes off intact, but the team also flagged a possible hinge stress point that lines up with early reports of inner-screen cracks. For a first-generation foldable, the internals look thoughtful; the long-term durability story is still being written.
