Which should you buy?
The Xiaomi 15 Pro edges ahead on the Mars Score (70 vs 74), but the 4.0-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Xiaomi 15 if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight.
Pick the Xiaomi 15 Pro if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are ram, pixel density, battery capacity, among others.
Both ship with comparable main camera, refresh rate, 5g support, so those specs don't separate the two — focus on the differences below.
Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
