Verdict: REDMI Note 15 Pro+ 5G ahead on 1 row, Xiaomi 17T on none

On the makers’ published figures, the REDMI Note 15 Pro+ 5G wins on fast charging (100 W against 67 W). 4 gaps are borderline, differences most people would not notice: display size (6.83 in against 6.59 in) for the REDMI Note 15 Pro+ 5G, peak brightness (3,500 nits against 3,200 nits) for the Xiaomi 17T, RAM (12 GB against 8 GB) for the Xiaomi 17T and battery per charge (65.67 h against 60.78 h) for the Xiaomi 17T. The difference in weight is below the threshold you would notice. Both state the same refresh rate, storage (base), battery capacity and battery lifespan. 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.
