Didn't know that, but it's great!
Your welcome. Also follow some of devildogs suggestions. Calibrate your meter by Power your phone off and charge until it is 100%. You can check the state of charge by pressing volume down. Once charged to 100%, turn on and use it till you get the low battery warning (about 10%), then power off again and charge til 100% with the phone off again. Then you can use and charge your phone as you please. It is recommended to do this cycle every 2-3 months.
Turn off notifications for emails, fb,twitter, etc that you don't need and change your emails to check for email as little as possible (every hour or every four hours or more is best).
Turn off data, Wi-Fi and sync when your not using it. Easiest way to do this is use the Smart Actions battery defender.
And make sure your phone is set to LTE / CDMA mode instead of global (it sets to global by default). Go to your phone settings --->more... (under data usage) ---> mobile networks ---> network mode ---> select LTE/CDMA.

All of the suggestions in this thread are great but aren't all these functions a features that we are diabling, what make the phone so great. There is a much easier fix, extend your battery. You can get a Droid Razr Battery upgrade kit and get two and a half times the juice and keep all your feature and functions working as they are intended to. Checkout cellphone repair shop.com and you will find the kit.
