I posted this in another thread but I'm going to paste it in here.
A few statistics from my day and battery usage.
Battery Percentage - 28% (Discharging from 100%)
Time on Battery - 11 Hours and 40 Minutes
Screen - 58% (3 Hours and 55 Minutes)
Voice Calls - 15% (45 Minutes and 33 Seconds)
Wi-Fi - 7% (Running 11 Hours and 33 Minutes, but wasn't actually connected to a Wi-Fi network until hour number 10)
Phone Idle - 7 Hours and 38 Minutes
Tapatalk - 4%
Chrome - 3%
Android System - 3%
Cell Standby - 2%
Bluetooth - 2%
A few notes to consider is that during most of my screen on time, I was surfing the web on Google Chrome and Android Central on Tapatalk. I also spent a little bit of that time text messaging and messing with widgets and such but that wasn't for long. Approximately 97% of my screen on time would have been during internet usage of some sort. I have my brightness set to automatic and due to the bright environment, I was at a pretty high setting all day. I was on 3G most of the day but in the beginning of my day it kept losing data signal and switching between 4G LTE and 3G. That was where quite a bit of my battery drained. I do not have any applications such as Facebook, Twitter, etc. updating at any intervals. WeatherBug Elite, however, updates every 6 hours and Comcast XFINITY every hour because you can't set these to not auto-refresh so I just set them to the maximum time allowed. Overall, I'm extremely happy I chose the Maxx over the standard HD because the extra juice is always welcome. Coming from the RAZR Maxx, the HD last as long if not longer so I'm very happy. Motorola has created the elite device in the Android market and possibly cell phones in general. Superb battery life with an HD screen on an open operating system just screams awesomeness!
