Verdict: Xiaomi 17T ahead on 2 rows, Nothing Phone (4a) Pro on 2 rows

On the makers’ published figures, the Xiaomi 17T wins on storage (base) (256 GB against 128 GB) and battery capacity (6,500 mAh against 5,080 mAh); the Phone (4a) Pro wins on peak brightness (5,000 nits against 3,500 nits) and battery lifespan (1,400 cycles against 1,000 cycles). 4 gaps are borderline, differences most people would not notice: display size (6.83 in against 6.59 in) for the Phone (4a) Pro, RAM (12 GB against 8 GB) for the Xiaomi 17T, battery per charge (65.67 h against 63.4 h) for the Xiaomi 17T and fast charging (67 W against 50 W) for the Xiaomi 17T. The difference in weight is below the threshold you would notice. 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.
