Why is my electricity usage so much higher in Winter?

@artyboy just be mindful that in this age of everybody being super frugal with electricity use, your new OLED TV should not be switched off at the wall (no mention on if you do or not but it has come up quite a bit of late), it needs to remain in standby when not in use. It needs to run compensation cycles when not in use and will show "screen burn" in no time if denied this.....and the manufacturer/retailer will blame you

Well that's a negative for OLED then.

We only replace TVs when they stop working and they go in a cycle from the snug to the bedroom to the gym when one breaks. (We don't do massive TV's as we have the projector for film nights in the Lounge. But this is useful info thanks didn't know this about OLEDs

OLEDs use much more power than a normal LED TV anyway.

We always assume that the standby usage of a modern TV is 0.5w.

If the TV runs now a pixel update every 4 hours as described here

what is the power usage during the pixel update? I doubt it is still only 0.5w

Anybody having a P110 or similar connect to an OLED TV?

Useful information! Never even considered that you shouldn't switch off an OLED TV at the wall. They do appear to use more power in use than a regular LED TV too.

Can't find any details on power usage, but it does appear it only runs for 5-7 minutes and only once while in standby after every cumulative 4 hours of viewing. So PROBABLY not much, but would be interesting to see somebody actually measure it.

Well I never knew that turning an OLED off could accelerate screen burn, so thanks for that useful info! It's always on standby anyway, from what I've read on here, more modern appliances aren't going to consume much power in standby mode so it's just the older ones that don't get much use that have been disconnected.

Like the first generation Nintendo Wii. And the VCR

I connected one of my LG OLEDs connected to an individual P110 for the first time yesterday.  The intention was to monitor energy use whilst in standby and to decide whether to put them on some sort of timer or just let it be.    It is not meant to be much in standby when not doing a pixel refresh.  Circa 0.5w.  However, some have reported between 15-25w.    This is what I found.

It uses 38w during the pixel refresh.  Pixel refresh stops after you hear an audible click (if you are close enough to hear it).

It then floated between 0.8w and 1.0w in standby.   So, I went to the settings and did the following:
1 - turn standby light off.  As expected this did very little.  It floated between 0.7w and 1.0w
2 - Then turned off the option to allow mobile devices to control the TV.  We don't use that.   It then dropped to 0.0w.  i.e. too low to register any use
3 - There is an option to turn on/off quick start which apparently can increase energy use when on.  However, it was already 0.0w with it on. So, I cannot tell if this made any difference other than it added about 3 seconds the turn on time. 

So, I have decided not to turn the LG OLEDs off at the sockets or run them with P110s and they can remain in standby with those revised settings.

For reference purposes, the above was an LG C7 55inch.   I did the same on my LG CX 55 inch and it uses a bit more at 41.8w during pixel refresh, but it too drops to 0.0w with the above settings turned off when pixel refresh is not running.

The sky Q mini boxes are power hogs. So, they should be turned off, but you need to leave the main Q box running.   I will probably post some figures on those later and I want to compare the internet connection via power socket or via wifi.  I suspect the power socket method will be cheaper as long as you turn wifi off on the sky boxes.

Useful info @dunstonh. Any idea how long the pixel refresh ran for? An extra 38W for 5 minutes each time you switch the TV off after 4 hours viewing doesn't really add up to much, so maybe it isn't so much to worry about.

The pixel refresh is not a fixed time.  It varies.   There are also certain points when it will run a longer one.     The C7 refresh on my test went off after about 10 seconds.  The CX refresh on my test went off some time after 5 minutes (I gave up looking after 5 minutes but it had stopped by 15 minutes).

The big refresh that happens less frequently takes over an hour.

Here is a graph from my P110 of my TV and SkyQ from 12:30 yesterday till now the peak of course is when my TV was on last night.

The 2 watt dip is when the SkyQ box goes into eco standby mode about 03:00.
My Sony  Bravia 49in TV uses about 50 watts when on and is not measurable when in standby and the SkyQ varies between 27 watts and 14 watts, except around 03:00.
I'm still trying to decide whether to switch it off at night.

Taking the average between 27 and 14 watts at the October price cap rate is about £90 a year if on standby for the whole year for Sky Q.
