This has only happened once to me, but i find it rather strange. I've had my droid for about a month now and with normal usage by the end of the work day (starting the day with a full charge) I typically have only depleted around 1/4 of my battery life. Just now at only 2:30 or so, part way through the day, I noticed that my droid battery was almost empty and i had the "please plug in" message. Seemed suspicious, so I checked to make sure no battery hogging processes were running and everything looked normal. On a whim, I restarted the phone. Upon booting back up the battery meter is displaying that it is FULL. Has anyone else seen this problem? Is this just a glitch or is it something to be concerned about?
