Talking about TVs

The biggest difference really is in standby and this is the same with all modern TVs, they are rated at 0.5w, but that is with WiFi turned off, with WiFi on and wake on app etc. in the background mine uses 25w and that seems pretty standard,

Its annoying that after the one watt initiative forced manufacturers to make products consume less on standby they are adding a feature where standby isn't really standby.

25w continuously for a year costs about £75 in electricity.

My 43" Toshiba is rated at 75w but it's stated usage is 54w
I believe it's around five years old, when it fails I will possibly get a larger TV. I don't believe a new TV will use less energy, but I will Google it.

I've just checked a 15+ year old panasonic tv which I use in my bedroom. Watched through its freeview tuner it uses 85w but when switching to a now tv box connected through HDMI it jumps to 110w. I've switched backwards and forwards between the two and tried different programmes to account for screen brightness. No idea how to account for the different energy consumption. The now tv box uses 2.5-3w and is on regardless of whats being viewed.

I disconnected my Freeview recorder and DVD player because they are never used and just consume power. I can reconnect when ever I wish.

A modern TV, especially an OLED will use a fair amount less when being actively used, although depending on how it is set up it could use more in standby due to the way WiFi and smart features are configured.

A modern TV(huge range there to lump into the statement) will never use less energy being used.

🤔 I'm scratching my head here even with the overhead of WiFi......will have a beer and think on that one.

Older TVs generally use more energy when in active use, less efficient technology, LEDs and various backlights have got more efficient and OLED is more efficient again.

Non-smart TVs use less power in standby due to the overheads of the smart tech, more so when WiFi stays active when in standby, network wake and app wake are running etc. In default configuration, they can be set to use as low as 0.3w in standby.

That 25W isn't normal. Our Sony uses 2W in what they call "network standby". I suspect there's something else going on.  Did you take a quick measure, or leave it for a while? Ours draws 11 or 12W when first put into standby, or if the power is restored, then after a two or three minutes it drops to the 0.5W (or 2W if networked)

Our LG OLEDs used 27W in standby with the mobile connectivity options on.   Wit it turned off, it uses an amount so small that the Tapo cannot register it.

We have three LG OLEDs.  2016,2019 and 2022 models.   The latest models use less energy than the earliest one.      Although the latest one is in the winter lounge where the room is darker and the brightness/contrast levels are lower.   The oldest one is in the kitchen under the brightest lights and runs with higher contrast/brightness.    So, that is more likely to the reason for difference.

The person you wer replying to was talking about a 5 year old TV I would presume smart and WiFi connected to be honest.
