Vivo - X200 vs Xiaomi 15

These two are nearly even on the Mars Score (71.7 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 X200 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 battery capacity, 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 wireless charging, weight, antutu.

Both ship with comparable ram, main camera, refresh rate, 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.
