Every phone I used somewhat disconnected from the web/wi-fi when I close the browser, email, or whatever app that was using internet connection but the N900 doesn't. For example, if I used 3g to browse then close the browser it takes hours to disconnect from tmobile 3g by itself. If I used wi-fi to browse or check emails, it doesn't disconnect when I'm done with email app. 3G disconnects after a while I guess but wi-fi never disconnects and drains the battery. Anybody else notice this?
