APC battery backup power consumption oddity..

Maybe my tech buds here can wrap there heads around this one.   I never thought I'd have such results like this.  

 

This 4K Xfinity box is sucking up so much power.  And I'm not even sure if it's the box entirely.

 

Let me know what you guys think

Not even a tech bud really.  I don’t even have any idea what that app is you are using in the video.  I did take science(!  So as to differentiate Science! from the actual sciences) class in the 7th grade.  I also don’t care as much as some if I look like an idiot.  So I’ll take a whack at it with copious hubris and guessing.

 

Electricity makes heat.  So this box should be getting pretty warm. YouTube likely compresses their stuff a lot. They have to pay real money to upload stuff, so it makes sense to compress things as much as they can.  And Google gots skillz. Xfinity might not have to though because they own the delivery system.  They could even turn the speed of your internet up only when you are only downloading stuff from their site. It is good to be the king and own everything.  I’d be curious to know if your bandwidth is maybe going way up when you run your thing on xfinity.  If a lot more bits were coming in the thing would have to work harder so more electricity and thus more heat.  It could also be a codec thing.  Xfinity gets to make their hardware too.  They could be doing all kinds of things.

You were displaying a very bright image at the start, and the YT video you showed was mostly dark. Local dimming will reduce power consumption of the TV a bunch if the content is dark. 

 

Processing will make a difference too but main impact is certainly the backlight, which accounts for a good 80-90% of a TV's power consumption.

There is an argument for a killawatt type device here to confirm where the power draw is actually coming from.  In my town you can check them out of the public library like a book so they don’t necessarily cost anything.   Not that they’re horrifically expensive to begin with.

The UPS does that already, just connect only one device to it at a time.

There is that I guess.  Might need some extension cords.
