Verdict: Galaxy A56 ahead on 1 row, Nothing Phone (3a) Pro on 1 row
On the makers’ published figures, the Galaxy A56 wins on battery lifespan (2,000 cycles against 1,400 cycles); the Phone (3a) Pro wins on peak brightness (3,000 nits against 1,200 nits). One gap is borderline, a difference most people would not notice: RAM (12 GB against 8 GB) for the Phone (3a) Pro. The differences in weight, display size, battery per charge and fast charging are below the thresholds you would notice. Both state the same refresh rate, storage (base) and battery capacity. 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.
