Verdict: REDMI Note 15 Pro+ 5G ahead on 6 rows, Pixel 9a on none
On the makers’ figures and the named third-party sources, the REDMI Note 15 Pro+ 5G wins on display size (6.83 in against 6.3 in), peak brightness (3,200 nits against 2,700 nits), storage (base) (256 GB against 128 GB), battery capacity (6,500 mAh against 5,100 mAh), battery per charge (60.78 h against 52.32 h) and fast charging (100 W from the maker against 23 W from GSMArena). One gap is borderline, a difference most people would not notice: weight (185.9 g against 207.1 g) for the Pixel 9a. Both state the same refresh rate, RAM and battery lifespan. The other 37 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.
