From what I have been reading from a lot of post on forums, I came to understand that "Froyo" has a built in task killer. so using a task killer only makes the problem worse.The problem I was having was I would task kill and 1 second later 17 more apps were open. I thought it was cause stupid carrier preloaded Skype and all these services that have to constantly run and when I task killed they would restart sucking juice from the battery. I uninstalled my "advance task killer" and tried like a few people have done and let the new software do its job. I have noticed a LARGE improvement.Also I have started using the back button, rather then just tapping home, to get out of apps as that's now how "Froyo" kills the apps. Also i have noticed, on the Easter egg of holding down the home key, that there is a utility called Rosie utility. I am not certain for 100% but I think that might be the "Froyo" Task kill. Hope this help anyone out there that factory reset twice cause I didn't want to read Pickle!
