I've had mine since early December. A couple of weeks after purchased it, I had just fully charged it and a couple of hours later (no usage) I got a warning that I needed to charge it. Which I did. The same thing happened a couple of hours later, again no usage. My battery showed the battery charge in the red. I rebooted the Droid and low and behold - 100% charged. This seems to happen about once a month. It seems it periodically needs rebooted or it misreads the battery charge. Has anyone else had this happen. I'm not a heavy user and do not have a lot of apps installed.
