I was in the same boat, I went from a Verizon G2 to the One M8 when the new red version came out. I do love the looks of the M8, the speakers are awesome, display is better IMO, however the rear camera is a lot worse (front facing camera is fantastic though). As far as battery goes, on the G2 when you unplug it you can keep it at 100% for a few hours before it starts going down, the battery on that just lasts forever. I noticed the battery on the M8 is significantly worse, I was using it this morning after fully charging it and using it for about 20-30 minutes it dropped from 100% to 90%. I did the same thing on the G2 and that thing stayed at 100% the whole time.
I'm returning my M8 and going back to the G2. The M8 is also about 1cm taller.

I don't know how you came to that conclusion, the battery can't be "twice as good" as the M7. Better, yes, but not twice as good. It's only a few hundred mAh larger, and it's 400mAh smaller than the G2.
