I am looking for a list of the apps that really kill/drain the DX battery the most. I know task killers are not supposed to be run to save battery life so I need to know which apps I can kill manually to maximize battery life. Right now I am barely getting through the day on a full charge (my DX is only about 3 days old though). Thanks. One other thing, any idea why Wifi keeps turning itself back on, even after I turn it off manually?
