It feels like every time daylight savings time kicks in, it seems to screw up some some form of technology. This time, Motorola is warning users on Android 2.3 that they may experience decreased battery life after the time change but a simple restart should fix the issues.
Motorola posted this message on their Twitter feed and does not give any more information about how dramatic the decrease in battery life will be. Fortunately, the issue is easily resolved and can be done with a simple reset.
If you do have a Motorola device running Android 2.3, it's probably best to go ahead and restart the device first thing in the morning to avoid any such issues. Last few times around Apple has had their own DST issues and one would hope that they have finally gotten on the ball and finally fixed the bug.
