The reason I purchased a droid razr maxx hd was for the excellent battery usage.  I was very happy with it till the kitkat update.  Now I have virtually no battery life, when before I could go at least 3 days.  I took it in to the local Verizon store and they were very nice, and tried the factory reset - spent a couple of hours -  no help.  I have tried to remain patient, assuming with so many documented problems that a fix would be in the works -   I'm running out of patience.  I would be happy if you could just come up with some way to go back to jellybean.   I am unable to use the phone for more than emergency contact, and have to keep it on airplane mode for the battery to last at all.  Please help!!!
