Curious for those with battery life issues are you on 4g or 3g does your area switch between 3g and 4g a lot? That could be some of the problem. It may not be but just a thought have you tried setting it to 3g only just for a day and see if your battery life is a little better? I have had 3 different Maxx's. The first one did good for a 10 days and then the sound stopped and my battery failed a few days later. The battery got super hot and would not hold a charge. My 2nd phone worked great until it fell out of my car charger and broke the screen. My third Maxx which I have had for a few days is doing fine with the battery they have all been pretty consistent which tells me that signal could play a role in battery life which you don't have a lot of control over.
