Same. Before this update I never, ever, used that button before. I have no clue what it used to do before update. And whatever that junk is that comes up when I swipe up, nope, don’t need it, don’t want it. I don’t want to use any buttons, or the crown. Before update I never used either.
Do you have a job where you sit all day? The more you move, the faster the battery drains. Wife and I have S7’s. Mine drains WAY faster than hers because I’m on my feet moving all day, she sits at a desk all day. Mine barely lasts a day, she can go two if she wanted.
