It may not be feasible in some cases (e.g. chargers) but unplugging devices entirely may be smarter than taping LEDs. Not every device needs to be in standby all the time. my granddad was obsessed with reducing power consumption and had built actual light switches into his living room walls that cut power for all TV devices at once. So in a way, the annoying LEDs also serve as a reminder that there’s a device consuming energy that we may not even be using 90% of the time.
