I got my Droid Eris yesterday and today, its first full cycle, the battery died after six hours. I've thus turned to using one of these applications to help extend the battery life. First off, what's the best "task-killing" application to use? Preferably one that's free. I am looking for an application that automatically takes care of the work without me having to manually kill all of the applications each time. I have both Advanced Task Killer and Automatic Task Killer installed. for Automatic Task Killer, how exactly do I configure it? Do I select all of the applications or just some? If just some, which ones should I select? Thanks for the help. Any is welcome.
