Which should you buy?
These two are nearly even on the Mars Score (74 vs 74.3). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
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. The biggest gaps in its favor are weight, battery capacity.
Pick the Xiaomi 16 Ultra if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are wireless charging, wired charging, antutu, among others.
Both ship with comparable ram, main camera, screen size, 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.
