Comparison review
Xiaomi 14 Ultra has a general score of 84.4, which is just a bit better than Xiaomi 12's global score of 78.8. Xiaomi 14 Ultra is a noticeably newer phone than Xiaomi 12, but it's somewhat thicker and somewhat heavier. These phones include Android OS, but Xiaomi 14 Ultra has the newer 14 version and Xiaomi 12 has Android 12, so it provides a couple nice extra features.
The Xiaomi 14 Ultra counts with a sharper screen than Xiaomi 12, because it has way more screen brightness, a greater screen pixel density, a higher resolution of 1440 x 3200 pixels and a little larger display. The Xiaomi 14 Ultra has a much better memory to install games and applications than Xiaomi 12, because it has more internal storage.
The Xiaomi 14 Ultra and Xiaomi 12 both have quite similar processors, and although the Xiaomi 14 Ultra has a larger amount of RAM, they both have 8 cpu cores. The Xiaomi 14 Ultra features just a little bit longer battery performance than Xiaomi 12, because it has a 5000mAh battery size. The Xiaomi 12 captures a little bit better photos and videos than Xiaomi 14 Ultra, because although it has a smaller camera aperture which is worse for taking photos and video in low light situations and lower 24 fps video frame rate, and they both have a same resolution back-facing camera and the same 7680x4320 video definition, the Xiaomi 12 also counts with a much bigger back-facing camera sensor taking more light and vivid colors.
