Verdict: REDMI Note 15 Pro+ 5G ahead on 4 rows, Galaxy A56 on 1 row

On the makers’ published figures, the REDMI Note 15 Pro+ 5G wins on peak brightness (3,200 nits against 1,200 nits), battery capacity (6,500 mAh against 5,000 mAh), battery per charge (60.78 h against 44.57 h) and fast charging (100 W against 45 W); the Galaxy A56 wins on battery lifespan (2,000 cycles against 1,000 cycles). One gap is borderline, a difference most people would not notice: claimed video playback (29 h against 25 h) for the Galaxy A56. The differences in weight and display size are below the thresholds you would notice. Both state the same refresh rate, storage (base) and RAM. The other 33 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.
