Which should you buy?
The MIX Fold 4 is the clear pick on raw spec strength, leading by 11.2 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 you photograph or shoot video regularly and want the better imaging pipeline of the two. The biggest gaps in its favor are front camera, weight, pixel density.
Pick the MIX Fold 4 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, refresh rate, 5g support, so those specs don't separate the two — focus on the differences below.
Bottom line: the MIX Fold 4 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
