Shut down apps

Swipe up and pause to bring up the app switcher. once the app switcher is up, rest a finger on the apps and a red badge will come up. you can then either swipe up on the apps or tap the red badge to force quit them.

 

shutting down apps messes with the Apple memory management system. This is why Apple made it harder

 

Yes, but don’t bother until an app has become unresponsive or otherwise faulty.

 

I'm in the habit of shutting down apps that seem to drain your battery when they're open in the background (Maps and Snapchat are two that come to mind).

 

This is not the same thing as is being asked. On the old phone, double clicking would bring up the app switcher and you’d swipe it away. Your video above shows the way to do this now. BUT..., in the past if an app froze, or if the phone froze, you could hold down the side button, and then when the turn off swipe option came up, you could hold down on the home button to force a respring of the app, or the phone. With no home button now, I cannot find a way to force a respring. Right now, it seems like the only way to get out of a freeze is to reboot the phone completely.
