Same problem on my wife's S9+. Used to unplug at 5:00AM and make it to 9:00PM with 40% left. After update it hits 0% by 4:00PM. Completely unacceptable.
I have a note 9 that hasn't had any problems at all with the pie and one UI update. Can't see that there are any problems with runaway processes or anything else unusual between my note 9 and the s9+. We've cleared cache, reset battery callibration, and factory reset. Nothing has helped.
Is there seriously no fix for this?
