Verdict: Galaxy A56 ahead on 4 rows, Galaxy S25 on 3 rows
On the makers’ figures and the named third-party sources, the Galaxy A56 wins on display size (6.7 in against 6.2 in), storage (base) (256 GB against 128 GB), battery capacity (5,000 mAh against 4,000 mAh) and battery per charge (44.57 h against 37.27 h); the Galaxy S25 wins on weight (162 g against 198 g), peak brightness (2,600 nits from GSMArena against 1,200 nits from the maker) and Geekbench 6 (CPU, multi-core) (8,599 against 3,701, both from Geekbench Browser). 2 gaps are borderline, differences most people would not notice: RAM (12 GB against 8 GB) for the Galaxy S25 and fast charging (45 W from the maker against 25 W from GSMArena) for the Galaxy A56. Both state the same refresh rate, claimed video playback and battery lifespan. The other 35 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.
