TechRadar compares iPhone Duo and Galaxy Z Fold 8 specs

TechRadar published a specification-by-specification comparison of Apple's iPhone Duo and Samsung Electronics' Galaxy Z Fold 8 on October 26, setting the two book-style foldables side by side across display, durability, camera and price.

Both phones carry a 7.6-inch inner display. The cover screen measures 5.4 inches on the iPhone Duo and 5.5 inches on the Galaxy Z Fold 8. According to TechRadar, Apple's nano-texture coating reduces the visible display crease, while the Galaxy Z Fold 8 shows more noticeable vertical creasing under light.

The Galaxy Z Fold 8 weighs 201g against 254g for the iPhone Duo, and measures 4.5mm unfolded and 9.7mm folded, versus 5.2mm and 11.3mm for Apple's device. The iPhone Duo carries an IP68 rating and the Galaxy Z Fold 8 an IP48 rating.

Stylus, multitasking and cameras

Samsung dropped the digitizer layer from the Galaxy Z Fold 8, so it does not support S Pen input. The iPhone Duo works with Apple Pencil USB-C but cannot charge it while attached. The Galaxy Z Fold 8 runs up to three apps at once through split screen and floating windows, while the iPhone Duo's iOS 27 split-screen multitasking is limited to two apps.

Inside, the iPhone Duo uses the A20 Pro chip and the Galaxy Z Fold 8 uses the Qualcomm Snapdragon 8 Elite Gen 5 for Galaxy, both built on 2nm processes with batteries of around 4800mAh. The Galaxy Z Fold 8 has a 10MP inner camera in a hole-punch cutout; the iPhone Duo hides a 4MP camera under the pixels and uses Touch ID instead of Face ID.

The iPhone Duo starts at $1,999 for 256GB and the Galaxy Z Fold 8 at $1,899, with Apple offering up to 2TB of storage against 1TB for Samsung's phone.
