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’m actively upset about how much worse the new battery statistics are. I wouldn’t even be able to tell you whether or not my battery life improved because the battery stats tell me nothing now
