how can you stop apps from auto-launching?

Apps sitting idle in ram use virtually no cpu/battery. Android automatically frees memory as needed so there's no problem with them sitting there. Autokill/manual kill use resources and are a waste of time.

Best bet is to avoid poorly designed apps that use cpu but don't get you anything. Example, I use a notepad app called Papyrus because it's the only simple one I could find that doesn't autostart. Try to cut down on widgets too. Antivirus and automated task killers are also a waste.

Automated task killers are like driving with one foot pressing the brake and one pressing the gas at the same time. Just let android do it's thing. Use an app's exit/quit button if it has one when you're done.

Again, this is just heresay

Background apps use memory. Their state information needs to be saved somewhere so it can be restored upon request. I imagine it's held in the volatile DRAM, which requires constant refreshing in order to maintain state, and thus, uses battery. CPU cycles? I don't know, but probably not.
