How long can I keep my xbox one s on for?

Suggest to put on instant power mode, is like having on low power eve you turn it off and the advantage is you can have the console up to date and able to download games overnight; if you don't know the instruction here:

Even works for xbox one s

I usually don't like leaving mine on all night but people have been known to do it. I would make sure to put a fan blowing in the area of your Xbox that should help keep it cool. Heat is your worst enemy.

there is no problem as many users do it to download games at night.

Hi! I'm Luis, a fellow Xbox Gamer . Thanks for reaching us out here.

As long as you have provided proper ventilation you should really not worry about it.

Also you are not demanding a lot from the console since you are only using a simple streaming app and not a graphically demanding game

I have the same question as MarkDeeDavis. I have an Xbox 360 E that is 8 months old (it's a replacement). Is it safe to leave it on for about 20 hours without using it? Sometimes I have unsaved progress on a school night, than have to leave it on from 9
PM-3 PM. The console is placed horizontally on shelf with plenty of fan room, but am unsure if it overheat if I keep it in a space like that.
