Hi guys, I've been reading on Task Killers and how it can drain battery life since it's on all the time.

Does it really harm more than it helps?

Also, if I don't install Task Killers... how do I turn off some apps? These apps have no "Exit" button. If I wanna use other apps, how do I manually kill the current app?

I use the back button all the time....

Now I realise that I can kill the task killer with the task killer. So I'll just bring it up whenever I need it.
