Comparison review
The Galaxy S21 Ultra is much better than Xiaomi 14, getting a 98.1 score against 79.4. Both phones we are comparing have Android OS, but the Galaxy S21 Ultra has the previous 11 version and Xiaomi 14 has Android 14. Even being the best device we compare here, it must be told that it's also a much older, somewhat heavier and a little thicker device.
Xiaomi 14 counts with a bit better looking display than Galaxy S21 Ultra, because although it has a just a bit less pixels per inch in the screen, a little worse 1200 x 2670 resolution and a little bit smaller screen, it also counts with a much brighter screen. Samsung Galaxy S21 Ultra has an extremely better processor than Xiaomi 14, and although they both have a Octa-Core processor, the Samsung Galaxy S21 Ultra also has a larger amount of RAM.
Xiaomi 14 counts with a very superior memory for games and applications than Samsung Galaxy S21 Ultra, because it has more internal memory. Samsung Galaxy S21 Ultra has a bit superior battery duration than Xiaomi 14, because it has an 8 percent greater battery size. Galaxy S21 Ultra shoots slightly better photographs and videos than Xiaomi 14, because although it has a smaller camera aperture which is not nice for shooting photographs or video in low-light environments and a smaller sensor shooting lower quality videos and photos, and they both have the same 24 fps video frame rate and the same 7680x4320 video definition, the Galaxy S21 Ultra also counts with a camera in the back with a way higher 108 mega-pixels resolution.
