How Much Power Does a TV Use When Off?
A TV that looks off can still use a small amount of power. In many cases, it uses about 0.5 to 1 watts continuously in standby mode, though some smart TVs may use a little more if network features stay active.
The Short Answer
- A TV that is off usually still uses a little power
- About 0.5 to 1 watt is a good rule of thumb
- Smart features and network standby can use more
Why It Still Uses Power
Many TVs are not fully shut down when you press the power button on the remote.
They often stay in a standby mode so they can turn back on quickly, listen for the remote, or keep certain smart features ready. They also need to keep their internal operating system running as well – since most smart TVs now are basically small computers.
What to Watch Out For
If the TV stays connected to a network, the standby power can be a little higher.
ENERGY STAR says TVs in standby-passive mode must be at or below 0.5 watts, and for network-connected standby-active mode the limit is 1.0 watt for qualifying models.
Best Simple Answer
Most TVs use only a tiny amount of power when off, usually around 0.5 to 1 watt. If you want it to use almost none, unplug it or switch off the power strip.
