Apple finally unveiled its first folding phone, the iPhone Duo, entering the competitive foldable market against Samsung's Galaxy Z Fold8. In terms of size, Samsung's offering is 53 grams lighter and thinner in both folded and unfolded states, featuring an aluminum frame, while the iPhone Duo sports a premium titanium build with IP68 protection compared to the Fold8's IP48 rating. Regarding displays, both devices feature nearly identical cover screens, though the iPhone Duo utilizes rounded corners and a larger corner-placed selfie camera.

The main displays share the same diagonal, but the iPhone Duo offers a sharper resolution and includes Nano Texture glass and stylus support absent on the Galaxy. Under the hood, the iPhone Duo is powered by Apple's 2nm A20 Pro chipset, claimed as the fastest in a smartphone, while the Galaxy Z Fold8 utilizes the Snapdragon 8 Elite Gen 5. Both offer 12GB of base RAM, though the Galaxy allows up to 16GB on higher storage tiers, whereas the iPhone Duo maxes out at 2TB.

In the camera department, the iPhone Duo features a 48MP main sensor, while the Galaxy Z Fold8 boasts a 50MP sensor with superior 8K video capabilities. Battery capacity remains unconfirmed for the iPhone Duo, with Apple citing up to 31-44 hours of playback. The Galaxy Z Fold8 houses a 4800 mAh battery.

Ultimately, the choice depends on user preference for iOS versus Android ecosystems and design priorities.
