Do I need to kill active apps in the Task Manager? Or will they eventually close themself?

I always thought you used the Home Button to "close" apps.
But some apps use the "Back Button" to close. (Like the Camera)

I didn't even know there was a Task Manager, and I had like 5 apps running.
Will they eventually close if left alone?

If the apps are left running will this drain my battery or use data?

Don't worry about it. Android handles task management very well by itself.
