Task Killers don't save battery (directly from developer of ATK)
I was raving on and on about how ATK (Advanced Task Killers) saved me from returning my phone.. and how it quadruple my battery life. I contacted the developer to thank them and make a donation, and told them of my experience.
This was their reply:
"Whether you need to use ATK or not, it all depends on if you need to terminate apps by yourself or by OS. I am not sure if there are any apps alive consume battery a lot. If you use ATK to kill some apps consume battery a lot, it might save your battery. But I have to say there isn't any app can save battery directly. Every app can consume resource and can consume battery. So I suggest you don't use ATK very often. According to google's investigation, 3g, wifi, internet, gps consume battery a lot. I suggest you turn off those kind of apps to see if your battery live a little longer.

I was floored... lol. A developer telling me not to use his product a lot. (Further emails back and forth have also additionally made it clear... task killers were not designed for the purpose of extending battery life.
I've removed it.
