Apparently, Motorola themselves have confirmed in a Tweet that they uncovered an odd problem with many of their Android smartphones. If you have a Moto phone that is running Gingerbread, you could experience weak battery life issues after the Daylight Savings Time change. Luckily, it isn't a major issue that will require anything drastic like a patch. In fact, all you need to do to fix the issue is reboot your phone. But you already do that once every week or two anyway don't you?
