That all true, but the comparison to others who aren't constantly using LPM wouldn't really be an apples to apples comparison then. Not to mention that using airplane mode consistently provides quite a bit more battery savings as well (on top of minimum brightness all the time). That is why getting higher numbers than many others isn't all that odd when all that is accounted for.Except low power mode doesn't limit anything I do on my phone, just like driving a sports car because you don't need to over 40mph because 40mph is the speed limit.
I can test again without low power mode if you really wanted. Sure low power mode greatly extends the battery life... THAT'S THE POINT. If it doesn't limit what I use my phone for I'd be silly not to take advantage of it.
Disables background app refresh - most people disable this by default because of the battery drain
Disables Siri - if have a use for a personal assistant, Google Now is better
Disables mail fetch - I don't need real time mail alerts... just check it manually
Disables automatic downloads - have it disabled anyways to save my data
Disables some visual effects - who would trade "fancy" animations for battery life
Caps CPU and GPU usage at ~60% max - even in games I don't notice any performance loss so...
