OMG, there are literally hundreds of tech articles stating that you do not need to, and should not, "close apps" because they are not running at all. It is cached data like your web browser history. Do you really wipe your web browsing history every time you surf the web? Please learn how your phone works before you write articles about it. I've only been writing apps since 2009, so you can dislike my comments all you like but the function was changed to stop people from creating battery drain by FORCE RESETTING apps all the time. They stay there to preserve time and therefore battery. leave them there unless you experience a malfunction; then force reset the app. They do not run in the background!!!
