ok, so im new to the android platform, but i have a couple of questions. First about widgets. I'm assuming these are pretty battery intensive, but are they draining battery when im not even on their page? so if i have a page full of widgets, but i dont actually go to that page on my xoom, will they drain the battery at all? Second, and more importantly, is there an app that creates a battery profile for on the go (like power saver mode) that would do something like dim the screen, turn off all widgets, and stop running things in the background, so lets say i was on the plane watching a movie, it would only use the basic resources necessary to play that movie and NOTHING else, all at the flip of a switch.
