Which should you buy?
The MIX Fold 4 edges ahead on the Mars Score (64.6 vs 71.4), but the 6.8-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the ThinkPhone 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, refresh rate, among others.
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, ram, antutu, among others.
Both ship with comparable main camera, 5g support, pixel density, so those specs do not 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.
