I'm sure the very environmentally conscious do do this. It's just a very niche thing to do, at least up until we're getting hit by monstrous weather several times over because of climate change :PI was only addressing the fact that nobody does stuff like this to save power, it's a matter of principle for the environmentally conscious, regardless of how small the "savings" are. I know the Switch isn't wasteful.
Regarding the unplugging, that's exactly what such types do, in my experience. One of my best friends fits this to a T and basically every outlet aside from his fridge and wifi stuff are switched off by default, she only turns stuff on to use them and turns them off again when done using them.
Also, you guys keep mentioning "unplugging", are outlet/extension switches not a thing in the US or what?
They are but, by being plugged in, they'd still be drawing at least a little bit of power, unless they also kill the connection completely to the outlet. I keep mentioning unplugging because folk on here keep thinking that the PS4 / XB1 / TV are completely off when they're turned off, even though they're actually still drawing power to receive signals from the controller / remote
That's honestly about right. They are designed to be rarely turned off or go through full power cyclesSo, I'm not aware of any data on what I'm about to say, but my guess would be that modern well-designed Li-Ion battery devices are actually best left plugged in.
The reason is that the batteries have lifespans depending on how many times they've been cycled. While they are unplugged and turned off, they still at they very least have to power the microcontroller that reads the power button. If they are plugged in, the charging circuit will top up the battery and then leave it alone, while still feeding power to the device.
Overall, the difference probably isn't significant. But I think there's a reasonable argument that leaving them plugged in is more materially efficient due to lower stress on the battery
