A couple is questions: 1. I've installed Advanced Task Killer and I use it fairly regularly, but I don't understand why I keep finding apps I'm not using popping up when I check it. For example: when I finish online I turn off 3g or WiFi and use task killer to turn off internet. But I also find half a dozen other apps running, things like Clock, Messages, Last FM, etc. Can I stop that from happening? 2. I keep hearing that the display really eats battery life, but when I check Battery Usage in 'About phone' the things that between them account for about 90% is battery use are 'Phone idle', 'Cell standby' and 'Android system'. Display has used around 7%. Does that sound right?
