Rumored — not yet announced. Apple has not confirmed Apple iPhone Duo or any specification on this page. Everything below is drawn from leaker and analyst reporting, cited to its original source in our news coverage. Last updated 2026-09-10; this page will be rebuilt with confirmed specs once Apple officially announces the device.
Apple iPhone Duo
Expected to announce September 9, 2026 (confirmed) · Expected release October 23, 2026 (confirmed)
What's rumored so far
Apple's first foldable iPhone is real, and it's called the iPhone Duo — not "iPhone Ultra" or "iPhone Fold" as pre-event rumors guessed. It unfolds to a 7.6" Super Retina XDR display with a nano-texture finish, and folds down to a 5.4" outer screen; both panels run ProMotion and peak at 3,000 nits outdoors. It supports Apple Pencil — a first for any iPhone — and ships in dark blue and white. Starting at $1,999, it's the most expensive iPhone Apple has ever sold. No score yet, and with an October 23 ship date, real reviews are still weeks away.
Every spec here is Apple-confirmed or sourced directly to post-keynote coverage (TechRadar's live event blog, Popular Science, Fox Business) — a big change from this page's pre-event version, where even the device's name was genuinely unsettled between "Fold," "Ultra," and "Duo" across different outlets' rumor reporting. How the hinge and crease actually hold up under real use is still unknown — that's exactly the kind of thing no announcement can tell you, only weeks of hands-on testing after the October 23 release.
