If you have a android cell phone and you actually use it meaning all the features (online, messaging, texting) then you know that your battery life will die really fast. See even if you exit a feature it doesn't mean it stops running in the background. So how do you turn off those apps to save your battery life? Well there is a app for that: Advanced Task Killer (FREE). You can download it in the android market place. I noticed a HUGE difference in my battery life after I started using this. To see the apps you have running you simply open it and the running apps will have a check next to them. All you do is uncheck the apps then hit the "Kill selected apps" button!
