Head to head

Apple iPhone 17 ProvsApple iPhone 15 Pro

The short answer

Choose the iPhone 17 Pro for peak brightness, more base storage and video playback time. 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 2032–2036 for the iPhone 17 Pro and 2030–2034 for the iPhone 15 Pro, our estimate, not Apple’s.

Verdict: iPhone 17 Pro ahead on 3 rows, iPhone 15 Pro on none

On the makers’ published figures, the iPhone 17 Pro wins on peak brightness (3,000 nits against 2,000 nits), storage (base) (256 GB against 128 GB) and claimed video playback (31 h against 23 h). 7 gaps are borderline, differences most people would not notice: weight (187 g against 204 g) for the iPhone 15 Pro, display size (6.3 in against 6.1 in) for the iPhone 17 Pro, RAM (12 GB against 8 GB, both from GSMArena) for the iPhone 17 Pro, battery capacity (3,998 mAh against 3,274 mAh, both from GSMArena) for the iPhone 17 Pro, fast charging (40 W against 20 W) for the iPhone 17 Pro, wireless charging (25 W against 15 W) for the iPhone 17 Pro and Geekbench 6 (CPU, multi-core) (8,770 against 6,830, both from Geekbench Browser) for the iPhone 17 Pro. Both state the same refresh rate, typical brightness and HDR peak brightness. The other 36 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.
