Buying advice

Which should you buy?

The Xiaomi 15 edges ahead on the Mars Score (64.6 vs 70), but the 5.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the ThinkPhone 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 refresh rate, screen size, weight.

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, antutu, ram, among others.

Both ship with comparable main camera, 5g support, water resistance, so those specs don't separate the two — focus on the differences below.

Bottom line: the Xiaomi 15 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
