Apple iPhone DuovsApple iPhone 18 Pro
The short answer
Choose the iPhone Duo for the larger screen. Choose the iPhone 18 Pro for lower weight. The iPhone 18 Pro is £800 cheaper at UK RRP (£1,199 against £1,999). Apple publishes no date for either; its record with retired iPhones points to 2033–2037 for both, our estimate, not Apple’s.

Verdict: iPhone Duo ahead on 1 row, iPhone 18 Pro on 1 row
On the makers’ published figures, the iPhone Duo wins on display size (7.6 in against 6.3 in); the iPhone 18 Pro wins on weight (211 g against 254 g). One gap is borderline, a difference most people would not notice: claimed video playback (34 h against 31 h) for the iPhone 18 Pro. Both state the same refresh rate, peak brightness, typical brightness, HDR peak brightness, storage (base), RAM and wireless charging. The other 32 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.
