theres always going to be tasks running in the background, but android by default is managing those tasks efficiently so you don't need any sort of task killer.

android apps that have been "backgrounded" are not using any CPU resources. they don't need to be killed. It's a concept that's a bit hard to grasp for those new to Android... but it's quite smart how it manages the lifecycle of an app. The less user-intervention there is, the more efficiently your phone runs.

On occasion, a badly coded app might start hogging CPU (like it gets itself in an endless loop) at which time, the best course of action is to manually kill the task. Other than that, don't think about what's "still running." just because it shows up in the list doesn't mean it's "running."

I should clarify that apps can be run in service mode (like your music player, GPS navigation, etc) in which case the app IS using CPU and/or radio resources. These are intentionally backgrounded and active and also should not be killed by a task manager. You should enter the app to stop the service.

sorry for the triple-post. This article is written by someone who helped develop Android and explains in a very clear, down-to-earth way how the app lifecycle works and why you shouldn't kill tasks:
