The Galaxy S21 Ultra is much better than Xiaomi 14T, having a global score of 98.1 against 83.7. Although the Galaxy S21 Ultra is a better device than the Xiaomi 14T, it must be noted that it is also extremely older, somewhat thicker and heavier. These devices use Android operating system, but the Galaxy S21 Ultra has the previous 11 version and Xiaomi 14T has Android 14.
Xiaomi 14T counts with just a bit better looking screen than Galaxy S21 Ultra, because although it has a bit less pixels per inch of screen, a little smaller display and a little bit lower 1220 x 2712 resolution, it also counts with way more brightness. Xiaomi 14T counts with a way bigger storage for applications and games than Galaxy S21 Ultra, because it has 128 GB more internal memory capacity.
The Galaxy S21 Ultra has a much faster processor than Xiaomi 14T. Both of them have 12 GB of RAM and the same number of cores. The Galaxy S21 Ultra takes much clearer pictures and videos than Xiaomi 14T, because although it has a tinier diafragm aperture which is worse for taking photographs in low-light situations, it also counts with a much better 7680x4320 video resolution, a lot better 108 megapixels resolution camera in the back and a bigger back-facing camera sensor taking better quality pictures.
Xiaomi 14T has a battery lifetime that is just as good as Samsung Galaxy S21 Ultra's battery life.
