I downloaded autokiller a few days ago. Now I don't know how to use it and I heard it saves a lot of batt. So I want to learn how to. I put the setting to aggresive and that's all I've done. How do u kill all the apps that r running on the backround? I kept my task killer and every time I open it there's a whole list of apps open I don't know why, I thought auto killer is suppouse to kill all the apps running in the backround. So if anybody has any info. Please let me know thank you in advance.
