My battery has never been worse since upgrading to Froyo. I don't use an auto task killer but I did use SystemPanel to manually close applications once in awhile. Now that I can't kill tasks easily, I just let everything run to see how it would turn out. I'm not saying the battery life is horrible, but it is noticeably worse now. I realize users experience will vary based on how many applications they have installed and running. I have not installed any new applications since Froyo. Anyone else seeing the same trend?
