For anyone new major Android update you should be doing a factory reset. I did the same after going through 4 beta updates and battery life is back to the good days where it definitely took a hit during the beta period. Still closer to 6 hours of on screen (I'll typically end the day around 3 hours or so, with 50% left).
Yeah, I finally reset it. We'll see how it goes. I kinda want an S10 anyway.
