That's an interesting idea. I might have to try it. 7 hours and 9% is really good. One day I took it off the charger set it down for the whole day. Did not use it at all. When I came home and looked at the battery it was at about 1/4 left. About 14 hours with no usage. Makes me believe it could be something running in the background, but I can;t imagine what it might be. I don't have much installed on it.
