Video playback problem when run on battery

I am using Win10 and since last 3 or 4 weeks I am facing the problem of video playback on any platform when on battery. I’ve checked with other browsers on battery, but I don’t get to see any such problem in them. Only it in brave. Be it any platform Youtube, Vimeo, etc.

Please fix this bug at the earliest, as it is creating a productivity hinderance.

Thanks and Regards.
