Normally i agree but.
Im still on the 12.5.20, which have been perfect for me all the time, amiui 12 to been perfect since the release day of the phone.
But now since the miui13 my phone start lagg and freeze, i never dropped my ohone or any other abuse and no new apps... Very weird yes, but its a fact which makes me sad, because i really like this phone. And i use the phone without playing at all, only normal daily use

I had the S21 ultra back in time to meanwhile i have this mi 11 ultra and i sold shamesong.
I will look for some weeks or i sell this and go back to my beloved mate 20x, is nothing change and miui13 is not and option, only want my phone stable and i see many people complain about it.... So this is MY reality.
Could be awesome if your good helping comment "Dont know how people can feel laggy with daily normal use of 11 Ultra" could help me... Thx btw, but it can't.
