Apple iPhone 18 ProvsApple iPhone 15 Pro
The short answer
Choose the iPhone 18 Pro for peak brightness, more base storage, video playback time and faster charging. The iPhone 15 Pro wins no row by a gap you’d notice. Apple publishes no date for either; its record with retired iPhones points to 2033–2037 for the iPhone 18 Pro and 2030–2034 for the iPhone 15 Pro, our estimate, not Apple’s.

Verdict: iPhone 18 Pro ahead on 4 rows, iPhone 15 Pro on none
On the makers’ published figures, the iPhone 18 Pro wins on peak brightness (3,000 nits against 2,000 nits), storage (base) (256 GB against 128 GB), claimed video playback (34 h against 23 h) and fast charging (60 W against 20 W). 5 gaps are borderline, differences most people would not notice: weight (187 g against 211 g) for the iPhone 15 Pro, display size (6.3 in against 6.1 in) for the iPhone 18 Pro, RAM (12 GB against 8 GB, both from GSMArena) for the iPhone 18 Pro, battery capacity (4,056 mAh against 3,274 mAh, both from GSMArena) for the iPhone 18 Pro and wireless charging (25 W against 15 W) for the iPhone 18 Pro. Both state the same refresh rate, typical brightness and HDR peak brightness. The other 33 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.
