Which should you buy?

Pick the Razr 50 Ultra 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, weight, screen size, among others.
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 wireless charging, wired charging, antutu, among others.
Both ship with comparable main camera, 5g support, front camera, so those specs do not 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.
