I have placed the sgs2 task manager widget on the front screen. Most of the times when I don't close apps properly I see the apps running in the background-according to the task manager widget. The apps deemed as running in the task manager is less than the "running applications" in the Settings>application settings. Apps which run even though I go back to the home screen include the social hub, messaging, etc. Google's own app does a good job to close the app when you press the home button. So should I still close all the apps and keep that widget running or its just using more battery by having the widget and closing apps?
