I don't have gsam installed. I did realize last night though that I forgot to turn on AoD so in my screenshots, I did NOT have AoD on. I have auto brightness on and it's pretty dark at my work so I'm guessing my brightness is low. I also have the screen resolution on WQHD+ and the screen timeout on 2 minutes. I do not let my phone sit idle with nothing going on just for the sake of showing high battery screen on numbers. The idle time is high because it was idle while I slept. If it makes you feel any better, when I woke up and woke up my phone it immediately went down to 99% and is down to 98% already since I used it for a bit while lying in bed.
I understand if you're skeptical but I've been around here a long time and I have no desire to mess with anyone. It's fine if you don't believe me though. I use my phone when I need it and maybe I just have good conditions? I also don't use FaceBook, which I believe is the root of many battery related issues. I mainly use Samsung internet browser, messages app, gmail, twitter, skype, and reddit. It is what it is. I'm happy with my battery life. I'm sure my battery life won't be as good today but it definitely does not go down overnight at all (or 1% upon waking up) and I am getting about 6-7 hour SoT average with plenty of battery left.
