Samsung built its foldable identity around the S Pen and then dropped stylus support entirely with the Galaxy Z Fold 7. It was also the first company to hide a selfie camera under a foldable's inner screen, and it axed that on the same generation. The iPhone Duo arrives with both. Apple Pencil works on the inner and the outer display, an under-display camera sits behind the inner screen, and the phone is rated IP68 against the Fold 8's IP48, which only keeps out solid objects of 1mm and larger. Digital Trends listed five places where the Duo has the edge.
Seven years of Samsung foldables have gone into hinges, screens and software, and Apple has turned up with the heavier phone. The Duo measures 11.3mm thick closed and weighs 254 grams, against 201 grams and 9.7mm for the Fold 8 and 215 grams for the Fold 8 Ultra. It starts at $2,000, and the Fold 8 is cheaper. On battery, Apple claims 26 hours of streaming video on the 7.8-inch inner display and up to 37 hours on the outer one, which works out roughly level with an iPhone 17 Pro if you live on the big screen.
