I totally agree and understand your frustration about tweaking or turning off features that you'll never use to get better battery life. But the flip of this is to then not buy a phone with such features such as a phone like the nexus 6. But then, even with a phone that has limited or no extra features, you would still likely have to tweak a setting or two if you want some extra battery life.
My point is that untweaked, my S6 gets 4 to 5 hours of SoT depending on how bright I need the screen to be. (again, that's with everything turned on max and even some things turned on that wasn't directly out of the box.)
Tweaked, I lose nothing or no features. But yet now I get 5.5 to over 6 hours of SoT. (again, mostly due to screen brightness and/or how much I'm using auto brightness)
Since I use my phones a lot, I use multiple wireless chargers to keep them topped up. Far better for me than the quick charger as my phone is now never below 50% at any moment of the day or night.
