I went to check what apps have been using my battery just recently and I found out that Asphalt 6 has been using 29% of it and it's not even open. I tried opening and closing it to make sure that it was closed but it still appears on the battery use app. I also tried using the Advanced Task Killer app to try to get rid of it but it doesnt show up yet it shows up for the battery use app. Any help?
