My new Philips dumb TV just arrived this weekend and I must say I'm impressed with the power draw. In default calibration, it draws 24w. But since it's in the bedroom and is only used at night, I've set it to ultra-eco mode and lowered the brightness for night viewing. Now the TV along an Amazon Fire TV stick powered by its USB port draw a combined 13w! In standby mode, the power draw doesn't even register on my meter.

If you're wondering how much energy is consumed by your electronics, a base model kill-a-watt for about $30 will show you watts and cumulative watt-hours. It's a fantastic tool that pays for itself besides giving an eye-opening, interesting experience. You'd be surprised at the things in your house consuming electricity 24/7. Almost everything in my house is either on power strip surge protectors or just unplugged.

I highly recommend the Athom smart home plugs preflashed with tasmota. No flipping cloud. None. Pick them up a fair bit cheaper than $30. And of course can turn them on and off over you local wifi - set timers over your wifi, or via mqtt for the whole smart home thing etc.

Point is they just work too if you don't want to do any of that. Plug them in, connect to their builtin wifi ap, read the power usage stats. Good button on the side that turns the power on and off too.

Esp8266 and a relay. Simple. Effective. Cheap. And just better than anything else I've seen in the space. Anyone has other recommendations I'm all ears.

A modern phone with a 5 Ah ( ~ 18.5 Wh) battery can run for many hours streaming to a builtin screen, meaning it uses far less (anything over 45 minutes is more energy efficient) than a chromecast despite doing more. Same scenario with a laptop with a 60 Wh battery, which can also run a long time in idle, and even while streaming, and is able to resume from sleep in a second. Running more than 2.5 hours on battery me…

Your smartphone does much less, not more.

When you are casting your smartphone on a built-in tv, the TV is doing all the work (downloading and decoding the signal). Your phone is just a fancy remote control.

The Chromecast is downloading the video and sending it to the TV on the contrary.

This may not sound bad, but it's the equivalent of 200 kWh per year and the set is only supposed to draw 0.5-1W from the specifications This would cost more than 50 EUR per year at current prices, and is sizeable compared to the average German citizens consumption of 1500 kWh electricity Let's just say this is not ideal given the current energy shortage in Europe...

200 kWh can run my tesla for about 1000KM just to give people a picture of the waste.

Not at the current prices for new customers. I'm currently paying 50,07€ct/kWh here in northern Germany. 25W * 8760h * 0,5€ = ~109€ per year. The price hurts, yes, but the waste of power is _criminal_.

Hah, wanted to say, nice current prices, can I have those? But you beat me, 0.41€, also Northern Germany.

I was ready for that. But it turned out that besides an idling rPI, modem, router and APs, nothing actually does. I have a bunch of zigbee connected smart plugs, and when I got those, I checked all my devices. Turned out regulations really do help, because all the standby usage was miniscule.

I've got a sony google bravia and have disabled everything I can think of, chromecast, remote start, bluetooth etc. Cannot get it under 12W when switched off. Can't believe I got suckered like that. There really should be consequences. Nobody would reasonably think their tv is sucking juice like that when turned off.

Can you link the model you purchased? I’m in the market for a new TV and Philips is literally in my backyard.

You could propably return it as defective. At least in EU there is a regulation about maximal standby power usage.

Don't forget to check power usage after a few minutes. My old Panasonic TV from 2007 would switch to a pre-standby state initially, then to a "deep standby" after about 60 seconds when the power usage dropped below 1 watt.

Regarding Sony, I found them the worst offender for standby power in my home stereo equipment which I've now replaced.
