Verdict: Galaxy Z Fold7 ahead on 2 rows, Galaxy S25 on 1 row

On the makers’ published figures, the Galaxy Z Fold7 wins on display size (8 in against 6.2 in) and storage (base) (256 GB against 128 GB); the Galaxy S25 wins on weight (162 g against 215 g). 4 gaps are borderline, differences most people would not notice: battery capacity (4,400 mAh against 4,000 mAh) for the Galaxy Z Fold7, battery per charge (40.47 h against 37.27 h) for the Galaxy Z Fold7, claimed video playback (29 h against 24 h) for the Galaxy S25 and 3DMark Wild Life Extreme (5,664 against 4,885, both from 3DMark) for the Galaxy S25. The difference in Geekbench 6 (CPU, multi-core) is below the threshold you would notice. Both state the same refresh rate, peak brightness, RAM, battery lifespan and fast charging. The other 34 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.
