¿Cuál deberías comprar?
The Z70 Ultra edges ahead on the Mars Score (75.1 vs 70), but the 5.1-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Z70 Ultra if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. The biggest gaps in its favor are ram, refresh rate, battery capacity, among others.
Pick the Xiaomi 15 if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are wireless charging, front camera, weight, among others.
Both ship with comparable main camera, 5g support, water resistance, so those specs don't separate the two — focus on the differences below.
Bottom line: the Z70 Ultra is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
