Galaxy S9+ battery deterioration after Pie Update

Terrible battery drain after Pie update! Trying a factory reset now. Battery life went from 42 hours to 19. Help. My phone is Galaxy S9+, Model SM-G965U, service provided by Sprint.

My battery actually has improved by 1 - 2 hours. I usually have my phone set to dark mode and the adaptive battery feature in pie OS gives me more SOT

Re: Galaxy S9+ battery deterioration after Pie Update

I already have the Adaptive Battery option chosen, as well as have nearly EVERY app go to sleep if not in use.  I also have chosen "Medium Power Saving" instead of "Optimized" Battery Setting, giving me an estimated 1 hour more.  Also, for the Display, I have nothing called "Dark Mode" - but think you must be referring to "Night Mode."  Do you use Night mode 24/7?

Did a factory reset - it helped slightly. I used to get 45 hours on one charge - now get barely 22 hours.

Even though I have most of the apps set to 'sleep' when not in use, I still see many running in the background.  For example, Chrome is set to "Put App to Sleep immediately when it's not in use" - but it ran in the background for 55 minutes, using 3% of battery.  How can I truly put apps to sleep/shutting them down when not in use??

What is using MOST of the battery is the Samsung Experience at 59%, followed by Android OS (using 9%), Android System {8%), Device Idle (6%), and Cell Standby (3%)

Update: Did a factory reset - which I hate doing.  It helped, but only slightly.  Battery life is barely 24 hours (down from 42-45) - if I don't use my phone much.  Very disappointed - wish I could somehow roll back this update.  SAMSUNG, are you listening??? Please address this.

Already have Adaptive Battery set...didn't even realize it.  Battery is almost dead right now - after 20 hours of only 2 hours of screeen time during that time.

Re: Galaxy S9+ battery deterioration after Pie Update

Yup.  I regularly got 40-45 hours on a charge.  I don't use much screen time on my phone and have always had it set up so apps go to  'sleep' when not in use. Have always checked that nothing is on in the background when I go to sleep.  Battery used to go down 2-3% during the night.  Now it's down 25%.  If you have any suggestions, I'd love to hear them!
