Maxx user here, I've had it since the release day. I don't think I can switch to any other phone because I average 3-4 hours of talk time, hundreds of texts, stream music ten hours a day, and the battery is still at 40-50% with wifi and gps on at the end of the day.
Wireless charging is also awesome, which is built in.
The Maxx is also very easy to de-bloat, and there is no real reason to root this phone, because of how open the software is to begin with.
I think I paid $499 for my Maxx, now it's free with a 2 year contract. If I had to get a new phone right now, I would go with the maxx again.
edit: here is my battery roll for the last 24 hours
