Which should you buy?
The Xiaomi 15 Ultra edges ahead on the Mars Score (70.4 vs 73.8), but the 3.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Poco F7 Ultra if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are wired charging, weight.
Pick the Xiaomi 15 Ultra if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. Its strongest claims are wireless charging, ram, pixel density, among others.
Both ship with comparable main camera, refresh rate, 5g support, so those specs do not separate the two — focus on the differences below.
