This is purely anecdotal, but every so often I have a day where my battery is just shot before it's even lunchtime. I can usually pinpoint it to one of several apps, because the problem is ailed by force quitting those that I know are apps I used recently but don't usually use often. That by no means says that force quitting all apps constantly does any good, but there are exceptions to where some apps just try to use more resources than you'd like, even when in the background.
