Apple iPhone 18 ProvsSamsung Galaxy Z Fold8

The short answer

Choose the iPhone 18 Pro for video playback time. Choose the Galaxy Z Fold8 for the larger screen. The iPhone 18 Pro is £500 cheaper at UK RRP (£1,199 against £1,699). The Galaxy Z Fold8 gets security updates until July 2033; Apple publishes no date for the iPhone 18 Pro, 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: iPhone 18 Pro ahead on 1 row, Galaxy Z Fold8 on 1 row

On the makers’ published figures, the iPhone 18 Pro wins on claimed video playback (34 h against 26 h); the Galaxy Z Fold8 wins on display size (7.6 in against 6.3 in). 2 gaps are borderline, differences most people would not notice: battery capacity (4,800 mAh from the maker against 4,056 mAh from GSMArena) for the Galaxy Z Fold8 and fast charging (60 W against 45 W) for the iPhone 18 Pro. The difference in weight is below the threshold you would notice. 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.

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.
