I only had my Droid X a few days before the update came out so I dont have anything to compare to. I have read that the update has built in to it something to kill running apps after some time and that you shouldnt run any app killer program. My battery life has not been very good even after the update. I have removed advanced task killer in hopes it would improve. I think I have returned my settings to where they were when i got the phone, hoping the update would make a difference over time. I just made these changes today, but am thinking somethings not right. I just looked at my running apps and I counted about 70 apps/programs running, many of which I havent even used today. Is the phone supposed to be killing these apps after a certain amount of time, or do I have to constantly manually close them? What do you have to do to manage this?
