I have to concur, if you have to have a extended battery just to keep yourself out of trouble then you have bigger issues. As said before, slim down on the apps you have running in the background, if needed disable some from starting with the phone by using something like MemMaid. Get a memory manager that can manage and free memory when it reaches a certain level or a task manager that you can use to close apps running in the background. I think my biggest hog is PIE(+).
