Weight

254 g

At 254 grams, the iPhone Duo is heavier than the iPhone 18 Pro Max, though it has the smallest footprint of the foldables compared.

Its outer screen is 5.4 inches, and a nano-texture layer on the inner display reduces the crease and reflections. The inner screen has a 1.4:1 shape, against 4:3 on Samsung's Galaxy Z Fold 8.
