I'm getting terrible battery life, like only two or three hours, and there is a huge difference between what WinMo reports and what Android says (like WinMo will say the battery is at 5%, while Android says it's at 96%).

Mind you, I was getting poor battery life on Fryo too. I replaced the battery not too long ago, while still on Fryo, so I don't think the battery itself is bad. I'm planning to wipe and reload GB and run it for a while with no widgets or any other customization, and see if some widget is the problem. Any other suggestions?
