Was thinking its from getting rid of the stock browser, stock email, and stock keyboard. Plus no longer having any widgets open except Power Control and Flashlight, but that's just a guess at why it got faster.
Rafael, I know you like the stock browser and email but you might wanna try Dolphin HD and use Gmail to try and increase battery life. You can always go back! I was reading that the stock Email actually wastes quite a bit more battery than gmail, because of how the notifications are received/sent. Supposedly no matter how long you set the notification interval it still keeps wanting to receive data anyways.
