Rumored iPhone Ultra Foldable: Design, Specs, and Market Implications

Rumors suggest the iPhone Ultra will adopt a wider “book-style” chassis, more akin to the original Pixel Fold than Samsung’s slimmer Galaxy Z Fold line. The wider chassis would enable a broader landscape orientation when opened, potentially reducing the letterboxing seen on the Z Fold 7. The device is expected to forgo Face ID in favor of a lock-button Touch ID sensor, a choice attributed to preserving thinness and screen real estate.

Analyst Ming-Chi Kuo reports a flexible main display of roughly 7.8 inches paired with a 5.5-inch exterior screen. Thickness is projected at 4.5–4.8 mm when unfolded—thinner than an iPhone Air—and 9–9.5 mm when closed. The phone would house two rear cameras (wide and ultra-wide) and a novel 3D-printed hinge. Bloomberg notes Apple’s use of “a new display technology that reduces the crease without eliminating it entirely.”

The wider chassis aims to differentiate the iPhone Ultra from Samsung’s upcoming foldable, which Samsung has teased as “much wider than before,” positioning Apple to compete directly in the 2026 foldable market segment.

Early reports flagged durability concerns for the 3D-printed hinge. Subsequent updates indicate those concerns have been addressed as the device entered test production, suggesting the hinge’s reliability may now meet Apple’s standards.
