YouTube always keeps experimenting to find ways so that people can keep on watching more videos on its site. The YouTube autoplay feature is one good way to keep the viewer on the site for longer. The YouTube auto play feature automatically starts a new video after the current video that you are watching ends.
To turn off the auto-play all you have to do is slide to uncheck the button that is present on the right menu next to the “Up Next” video (see in the image below).
When you turn it off YouTube will not start the auto play even if you close the browser or restart the system altogether.
