Biggest changes for me were:
-Disable Hotword detection. Turn it back on when you want to impress friends and otherwise hit the mic button manually. Increases Screen on Time.
-Disable Auto sync. Set an automation to only sync while charging instead. Increases Battery at all times, may slow charging a tad.
-Disable Locations. Enable if needed on the go. Can't automate this with Llama but I'm guessing it would work using Tasker. Many less wake locks you can go hours without a single one now.
