Hi I have several droid razr phones (not currently activated) and I was testing the batteries on all of them and noticed something funny. Of the 7 phones I have, four of them seem to drain quicker then the other three. I did all the updates on them, then gave them all a full charge. I let them all sit in the same area of the room for 48 hours and then checked them once the 48 hours was up. Three were about 50% drained, four had less then 10% battery left. So I was thinking the four with 10% battery left maybe had defective batteries. So I decided to remove the three good batteries and install them in the device that only had 10% left. So I charged them up again and ran the 48 hour test again, (this time with known good batteries installed in the devices). 48 hours later when I checked them, they once again showed less then 10% left. That hints that it is the phone that is causing them to drain faster, not a battery problem. One thing I noticed was all the ones that drain faster have two messages when I the home scree and swipe my finger down from the top it says "background data restricted" touch to remove the restriction. Then it also says active smart actions, low battery saver. The three phones that have 50% battery remaining after 48 hours does not have any messages when I swipe my finger down the screen. So that may have something to do with it, does anyone have any idea? below is a photo of the two messages that show up on one of the four that only last 48 hrs.
