Apple iPhone DuovsSamsung Galaxy Z Fold8 Ultra

The short answer

Choose the Galaxy Z Fold8 Ultra for lower weight. The iPhone Duo wins no row by a gap you’d notice. The Galaxy Z Fold8 Ultra is £100 cheaper at UK RRP (£1,899 against £1,999). The Galaxy Z Fold8 Ultra gets security updates until July 2033; Apple publishes no date for the iPhone Duo, and its record with retired iPhones points to 2033–2037, our estimate, not Apple’s. On that estimate neither clearly gets them for longer.

Verdict: Galaxy Z Fold8 Ultra ahead on 1 row, iPhone Duo on none

On the makers’ published figures, the Galaxy Z Fold8 Ultra wins on weight (215 g against 254 g). 3 gaps are borderline, differences most people would not notice: display size (8 in against 7.6 in) for the Galaxy Z Fold8 Ultra, claimed video playback (31 h against 27 h) for the iPhone Duo and wireless charging (25 W against 20 W) for the iPhone Duo. Both state the same refresh rate, peak brightness, storage (base) and RAM. The other 38 rows have no threshold or no direction to judge by, so nobody wins them.

Specifications

A win is marked only where the figures can be ranked and the gap is one you could notice. A row the site has no threshold for says whether the two differ, and that it is not ranking them. = marks the same figure on both, ≠ not ranked a difference with no ranking. Every figure carries its source.
