Battery life is so nice after the disappointing Galaxy Nexus. That phone had to be nursed to make it to bedtime, and I'm not a heavy user.
My three-day-old Droid Maxx is in heavy use because I'm still playing with all the doodads, and I've avoided plugging it in during the day just to see how it performs. It's never gone to bed with less than 30% battery. I even ran Navigate for 45 minutes yesterday without plugging it in, and it didn't flinch.
