don't forget the whole- turn off the TV not everything bit. I know I leave my cable box on so it's one less thing to power up.
Pretty disgusting, especially considering that most of them haven't had any of the technology updated in 10 years either. Pretty much explains why they stink. We could have set top boxes the that are much smaller an easily use an eighth of the power.
Sad thing is that you could literally replace the entire box with Raspberry PI and have it draw just milliWatts when idled and less than 10W fully operational... Hell, if they wanted to they could use a Snapdragon 805 (~5W) and allow all the bells and whistles they wanted to, including DVR, multiple video out, and increased compression of digital channels (they could easily fit everything in 30% less space by switching to a streaming h264 rather than ATSC). And all while costing a quarter of what they charge customers for a box!
