Not counting the added features, font and emoji changes since those are all subjective.
Since it was made available to me (T-Mobile S22 128GB) I’ve WAY less frame drops and the animations themselves seem smoother.
I haven’t had it long enough to notice a difference in battery performance but it’s something I plan to pay close attention to considering the terrible battery life the base S22 has had previously.
I don’t like new font, don’t like new buttons for wifi and BT in control center, new battery statistics is so terrible I stopped opening it as I am getting no useful information there.
Battery life - on some days seems better, on other days seems worse.
