I understand it鈥檚 not good to do because when open again it use more battery 馃. But very rear I experience that when there are a lot off apps open that my phone make apps slow and not even load. When I close some apps all fine again I think it still use some RAM in the background
I force-close apps because I only want to see my regularly used apps when I swipe up. I find it a more efficient way to switch between those apps.
Seeing every app when you swipe up is the equivalent of someone who stores all of their files on the desktop. 馃ぎ
