How we worked it out
A Switch docked to a TV draws about 6 W, and one AA holds about 3 Wh. Alkaline AA batteries, about 3 Wh each, and no energy lost on the way. Real life adds a little friction and waste, so treat the number as a solid ballpark rather than a lab result. The constants behind every experiment are on the science page.
