Reports from The Elec, as cited by MacRumors and Macworld, say Apple’s rumored book-style foldable iPhone—often referred to as “iPhone Ultra”—is preparing for mass production in late July and still targets a September launch. Earlier coverage suggested hinge-related concerns could cause delays, but more recent supply-chain reporting indicates the project is moving forward. The Elec describes earlier testing problems with a 3D-printed hinge module, including slight noise after durability tests involving millions of folding cycles and higher defect rates tied to manufacturing tolerances. Sources cited from Taiwan indicate these problems have largely been addressed, and that the device is entering preparation for mass production. 9to5Mac similarly reports that 3D-printed hinge issues appear solved and that recent reports point to an unveiling during the September keynote. The Elec also reports key component details: a Samsung-supplied 7.8-inch foldable OLED panel, and hinges sourced from Taiwan’s Shin Zu Shing and U.S.-based Amphenol. Mass production is expected to involve Foxconn for the initial batch, with Apple aiming for timing that remains aligned with its September plans.
