Wow. Maybe mine is in better shape that I thought. I routinely get through my day with 20-30% remaining. I'm not one of those people who obsess over every mA of power, but I like to think I'm smart about it. Display brightness at about 40% and AUTO, location to phone only, BT enabled, and WiFi automatically shuts down when I leave my home network. The only other thing that I've done is to disable most of the Verizon bloatware with Package Disabler. Oh, and I use a black theme with Nova.
I agree that the S7 Edge is a beast WRT power. I just picked up a new S8 yesterday, so we'll see how it compares. I really didn't need another phone because this Note is running really well, but I couldn't skip the low price this time. Someone (Samsung, Best Buy, or Big Red) is giving those things away, and I wanted mine.
