I was initially when I first activated the phone - after going through full cycle charges and monitoring it via Battery Sense app, it's getting better.
However, this isn't the reason - I just don't like having applications sitting in the background hogging up whatever resources tied to them.
Currently just using the back key to get to the home screen to kill whatever app I'm using.
Is there a better way? I wish we could close whatever application from the running application view (view you get when you hold down the back button).
