OnePlus 12 vs Xiaomi 15

These two are nearly even on the Mars Score (69.6 vs 70). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the OnePlus 12 if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. The biggest gaps in its favor are wired charging, pixel density, screen size.

Pick the Xiaomi 15 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 antutu, weight, water resistance.

Both ship with comparable battery capacity, ram, main camera, 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.
