Juice defender works well for me, Battery saving on an Android is based on 3 main things..
Screen Brightness + Screen Timeout(Dim it to save battery)(Set it to no more than a minute)
Data & Wifi (Turn em off when you don't use it) Juice Defender will do this for you
Apps you allow to access the internet at will and refresh themselves.
