Hi, I had the same problem with battery. I have: 1. Disabled background usage for Device care (the app that is responsible for the battery chart), deleted all the actualizations of this app and disabled autoactualize in play and Galaxy store. 2. Disabled permissions for Google play services. My SOT jumped from 3,5 hour to outstanding 6 hours. With 20 hours stand by time. Hope this will help You. Let me know if it worked for You.
