Comparison review
The Xiaomi Mi Mix Fold 4 has a general score of 84.3, which is slightly better than the Xiaomi 15's 80.6 score. Xiaomi Mi Mix Fold 4's body is incredibly thinner but somewhat heavier than the Xiaomi 15, and they were only released with a couple months difference. Both phones we are comparing use the same Android 14 operating system, so both of them should provide very similar operating system features.
The Xiaomi 15 has a little bit better looking screen than Xiaomi Mi Mix Fold 4, because although it has a way worse resolution of 1200 x 2670 pixels and a way smaller screen, it also counts with a quite higher number of pixels in each display inch and a bit brighter screen. Xiaomi Mi Mix Fold 4's processing unit is just as good as the CPU in Xiaomi 15, both have a 12 GB RAM and a Octa-Core CPU.
Xiaomi Mi Mix Fold 4 shoots just a bit better videos and photos than Xiaomi 15, although it has a smaller aperture which is not favorable for low-light captures and lower 24 frames per second video frame rate, they both have a same resolution camera in the back and the same 7680x4320 video quality.
Xiaomi Mi Mix Fold 4 has as much memory capacity to store more games and applications as Xiaomi 15, both have exactly the same internal memory capacity. The Xiaomi 15 has just a little bit longer battery performance than Xiaomi Mi Mix Fold 4, because it has 5400mAh of battery capacity instead of 5100mAh.
