ok. FIGHT! Seriously though, i uninstalled my task killer, on the basis that Android manages itself etc but today i installed it again. I just don't understand why my phone would have applications running that i have NEVER used, such as the FM radio. My phone was using the data connection, and i looked through all the applications that i thought may be using it, none were, ran the task killer, killed all the stupid applications that i have never opened and do not even use, and the data connection stopped. I would love to stop using the task killer, but why does this happen? surely there must be an impact on the battery? anyone out there who doesn't use task killer?
