Laggy's Life Hacks: Listening to YouTube with your iPhone screen turned-off/in the off-state

I loved listening to audiobooks. Some of them are on RUclips. I hate the idea of having an open video stream active on my screen, while it's in my pocket on a hike, while phone is in console in the car, etc. Well, I finally found a way to do it. Less likely to skip to next. Less drain on battery.
