After I updated to 2.01, like most people, I have found a significant increase in battery life (if you consider around 20% increase significant). That being said, this strange "bug" has happened to me twice. (Considering how much I use my phone, twice is pretty rare) I was doing something on the Droid (either scrolling through contacts or in the Market), when all of a sudden my screen went black. Nothing I did could wake up the phone, BUT the green indicator LED was still flashing (I think I had a new e-mail waiting). Then all of a sudden, the Droid rebooted. It was showing the Motorola "M" icon, and doing the red Droid startup screen thingy, but the green LED was still flashing. I know sometimes weird stuff happens, and the phone might just need to reset. However, the reason I find this strange is that the LED never stopped blinking.
