I honestly think the issue is that with a 2300 mAh battery and the usual set of Android apps installed (lots of which stay in the running area), the battery can be depleted very quickly. And if you use any push mail, like the stock mail app with Exchange, you'll see the battery drop extremely quickly. I have my screen set at 1-5% brightness and I still can't get a full day's usage out of the phone without recharging. I am guessing that Facebook has also made this impossible, along with its requirement to have Messenger and those damn bubble heads roaming wild. The foolishness about the 3000 mAh batteries in the new phones is that they run at an insanely high and needless resolution above 1920x1080, which means the battery benefit you might have gained is no longer a true gain. The One M8 is a negligible increase in power and the G3, which still seems unavailable, looks like it will feature the same or worse battery suck with the ultra high resolution screen.
