It also is illegal in the EU for new devices. https://ec.europa.eu/info/energy-climate-change-environment/... : “Network-connected standby devices Modern appliances are increasingly connected to the internet during standby mode, consuming higher amounts of energy. This includes networked televisions and decoders, printers, game consoles and modems. - Specific requirements for network-connected standby devices were in…

There were devices that consumed 80 watts in standby. I have a cabinet full of equipment including my cable modem, a computer (server, no monitor) with 8 mechanical hard drives. The idle current is 76 watts or so. How could something be so high?

'standby' for many devices used to mean 'leave all the electronics powered up, but turn the screen/sound off'.

I've a 2015 model that's becoming harder to use because of the outdated software and I'm not sure of a fix. The panel still looks great.

In which way is it becoming harder to use? The smart TV part of it?

It's simple enough to say "use an exterior device" (which I do), but even input switching is managed in software and can be a nightmare sometimes. It would be great if there was just a light OS install. It'd likely bring the power use down as well.

Audio amplifiers, especially old ones, can easily draw 100 watts when on 'standby' - ie. the amplifier is turned on but playing no sound.

If it is a class A amplifier, I think that would make sense. But how many people have huge class A amplifiers for their home audio?

For comparison, my external Nvidia shield (2019) consumes around 3W in standby and 8W max. https://www.guru3d.com/articles_pages/nvidia_shield_android_...

has anyone used these shields to convert old VHS tapes to digital?

Chromecasts in general seem like big power hogs... I don't need you to use 20 watts all the time to show a shiny background image and a clock...

I really wish users who spend "Just" $/€/£ 40 on a Chromecast knew that it is going to cost them the same amount every year on their bill. I think many of those people wouldn't buy one if they realised they are almost buying a subscription.

Google could adjust them to just don't send out any signal unless someone is actually casting. The chipset can totally do 0.1 watt sleep mode with wifi connected.

Depending on what you do either get an Nvidia Shield or an AppleTV. I'd recommend the Shield for Plex or the AppleTV for streaming Netflix, etc.

AppleTV is fully capable of playing local content. You can either use Infuse player or sideload Kodi

Old ones...

Everything from the 60's, 70's, 80's and 90's...

Remember in europe we have a lot more old stuff - especially old houses that are family owned for 100+ years tend not to have things replaced often unless they're unrepairable.

Even modern class D amps can be 30+ watts when not playing anything tho.

I have a 2020 model I bought from Costco and as slow and shitty the UI is it also still burns 16W in standby. There isn't a way to disable Chromecast either so thanks for nothing Sony and Google. I need a dumb tv and Nvidia sheild. Edit: I take the standby power usage part back. After settings changes including Eco stuff and something to do with remote start and a restart it's at 4W which is very acceptable. The UI i…

Go to Apps, “See all apps”, scroll down, find “Chromecast built-in” and then click Disable on the app’s settings.

At least that is how it’s on my Sony TV.

I have a Sony Bravia from the 2010s (a dumb one) that has a standby mode, engaged when you power off the TV via remote.

The TV also turns off-off when you use the physical button, but there's seemingly no functional difference, the unit still powers on via remote if fully off.

I have a feeling that all the physical power button really does is put the unit on standby, but also turn off the little red standby LED.
