Between the Razr 50 and Xiaomi 15 Pro, the Razr 50 comes out ahead in weight and screen size, while the Xiaomi 15 Pro wins on wired charging and antutu. Overall, the Razr 50 scores 60.2 and the Xiaomi 15 Pro scores 74 on our Mars Score.
Which should you buy?
The Xiaomi 15 Pro is the clear pick on raw spec strength, leading by 13.8 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the Razr 50 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 weight, screen size, water resistance.
Pick the Xiaomi 15 Pro 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 wired charging, antutu, wireless charging, 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: the Xiaomi 15 Pro is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
