Ok, there is room on both sides of the fence...
Third party stuff does not need to be running 24/7 unless you want it to.
Additionally, tweaking the memory management i.e. using
will make a HUGE difference in battery life. (this is from experience on a Samsung Moment) Before ATK and AMM battery would DIE within 8 hrs. I was able to go DAYS (yes DAYS) between charges after using both apps.
So, think what you want, but I am speaking from actual 'Droid experience, you NEED to tweek the memory/running programs if you want any kind of battery life.
