Apple iPhone 18 ProvsSamsung Galaxy Z Flip8

The short answer

Choose the iPhone 18 Pro for peak brightness and faster charging. Choose the Galaxy Z Flip8 for lower weight and the larger screen. The Galaxy Z Flip8 is £50 cheaper at UK RRP (£1,149 against £1,199). The Galaxy Z Flip8 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.

2 wins for iPhone 18 Pro2 wins for Galaxy Z Flip81 gap borderline1 difference you won’t notice£50 apart at RRP

Verdict: iPhone 18 Pro ahead on 2 rows, Galaxy Z Flip8 on 2 rows

On the makers’ published figures, the iPhone 18 Pro wins on peak brightness (3,000 nits against 2,600 nits) and fast charging (60 W against 25 W); the Galaxy Z Flip8 wins on weight (180 g against 211 g) and display size (6.9 in against 6.3 in). One gap is borderline, a difference most people would not notice: claimed video playback (34 h against 31 h) for the iPhone 18 Pro. The difference in battery capacity is below the threshold you would notice. Both state the same refresh rate, 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.
