Since the July update on my Note 9, I have noticed a major decrease in battery life. I can hardly make 12 hours on a full charge now. Before I would be at 25% to 30% at the point I'm down to 10% now and dropping fast. Hope there is a fix soon.
My battery life is now more like it was before the June update. I don't know what caused the improvement. One of the changes that I made was to enable Auto Restart, which can be found in device care. I have no idea if this helped but the July security update also came around the same time.
