Apple and Samsung have both entered the foldable market with high‑end devices that promise to redefine how we use phones. Apple’s iPhone Duo, unveiled on Wednesday, steps away from the rumored “iPhone Ultra” name and instead offers a palm‑size foldable that feels like a hybrid between a phone and a tablet. Samsung’s Galaxy Z Fold 8 Ultra, released earlier this year, pushes the foldable envelope with a taller book‑style design, a triple‑camera setup borrowed from its flagship S26 Ultra, and a 5,000‑mAh battery that should keep it running all day.
Design and Display
The iPhone Duo sports a 5.4‑inch OLED cover screen and a 7.6‑inch matte inner display that reduces glare and crease visibility. Its overall thickness is 5.2mm when open and 11.3mm when closed, weighing 254 grams. Samsung’s Z Fold 8 Ultra, by contrast, features a 6.5‑inch AMOLED cover and an 8‑inch internal display, making it taller and more slab‑like when closed. The Ultra is thinner at 4.1mm open and 8.9mm closed, and it is lighter at 215 grams.
Both phones boast high refresh rates—120Hz on the Duo’s cover and up to 120Hz variable on the Ultra’s displays. The Duo’s matte finish outperforms the Ultra’s anti‑reflective coating in low‑light conditions, while the Ultra’s larger screen offers more space for multitasking and media consumption.
Camera Systems
The Duo’s camera lineup is pared down to two 48‑megapixel rear lenses—wide and ultrawide—without a telephoto option. A 12‑megapixel front camera sits on the cover, and a 12‑megapixel under‑display FaceTime camera appears on the inner screen. Samsung counters with a 200‑megapixel wide, 50‑megapixel ultrawide, and 10‑megapixel telephoto rear trio, plus a 10‑megapixel selfie camera on each display. The Ultra’s camera hardware is shared with the S26 Ultra, suggesting strong performance in low light and zoom.
Processor, Battery and Charging
Under the hood, the Duo runs Apple’s A20 Pro chip, the same found in the iPhone 18 Pro series. The Galaxy Z Fold 8 Ultra is powered by Qualcomm’s Snapdragon 8 Elite Gen 5. Battery life on the Duo is quoted at up to 31 hours of video playback on the inner display and 44 hours on the outer screen, with a 24‑hour mixed‑use estimate. The Ultra’s 5,000‑mAh battery should comfortably last a full day under typical use.
Charging speeds differ: the Duo supports 60‑W wired charging (50% in ~20 minutes) and 25‑W MagSafe wireless charging, while the Ultra offers 45‑W wired charging (63% in ~30 minutes) and 20‑W wireless via Qi‑compatible cases. The Duo’s magnetic charging and MagSafe ecosystem give it an edge for users who value accessory integration.
Durability and Features
Durability is a key differentiator. The Duo carries an IP68 rating, allowing it to survive immersion up to 6 meters for 30 minutes and offering dust resistance. The Ultra only meets IP48, tolerating up to 1.5 meters of water and protecting against larger solids but not dust. Samsung’s build includes Corning Gorilla Glass Ceramic 3 on the cover and Victus 2 on the rear, while Apple uses Gorilla Glass Victus 2 and advanced aluminum framing.
Software differences are also notable. The Duo runs iOS 27 with Apple’s new N1 wireless chip, Thread support, and dynamic island features. The Ultra ships with Android 17 and One UI 9, offering a more familiar Android experience. Both phones support dual eSIMs and high‑brightness displays, but the Duo’s 3,000‑nit peak brightness gives it an advantage in bright outdoor settings.
Price, Availability and Who Should Buy
Both devices start near $2,000 for 256GB: the Duo at $1,999 and the Ultra at $2,100. Preorders for the Duo begin on Oct. 16 with a release on Oct. 23, while the Ultra is already available. Samsung’s Ultra offers a larger screen and stronger camera system, making it suitable for users who want a tablet‑like experience and advanced photography. The Duo, with its compact size, matte display and robust durability, appeals to those who prefer a phone‑like feel with foldable flexibility and a tighter integration into the Apple ecosystem.
Ultimately, the choice hinges on usage priorities: the Duo for compact, durable, ecosystem‑centric use; the Ultra for larger display, superior camera hardware and a more traditional phone‑to‑tablet transition.
