Verdict: Galaxy S26 ahead on 3 rows, Galaxy A56 on 1 row
On the makers’ figures and the named third-party sources, the Galaxy S26 wins on weight (167 g against 198 g), peak brightness (2,600 nits from GSMArena against 1,200 nits from the maker) and battery per charge (51 h against 44.57 h); the Galaxy A56 wins on battery lifespan (2,000 cycles against 1,200 cycles). 4 gaps are borderline, differences most people would not notice: display size (6.7 in against 6.3 in) for the Galaxy A56, RAM (12 GB against 8 GB) for the Galaxy S26, battery capacity (5,000 mAh against 4,300 mAh) for the Galaxy A56 and fast charging (45 W against 25 W) for the Galaxy A56. The difference in claimed video playback is below the threshold you would notice. Both state the same refresh rate and storage (base). 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.
