My husband and I both have Droid 4 phones, purchased on the same day. Today we both noticed a crazy drain on the battery. Seems like it started yesterday, but today my D4 was out of battery charge by 1pm and I had to charge it up to full. 4 hours later it was depleted again. This is with the phone in standby mode. I have also noticed that something is activating the screen from sleep mode, as I have the phone laying on my desk. The screen will flash on, but I do not see any new notifications. I have noticed that 4G is dropping in and out a lot lately - could this be what is draining our phone batteries?
