Xbox One on Instant On and turns off completely

To turn off Instant On, go into the Xbox One’s Settings by pressing the Menu button, and then Settings, or say “Xbox, go to Settings.” Then go to Power and startup.

Select Power Options, and then switch from Instant-On mode to energy-saving mode. This will allow the Xbox One to completely shut down.

Turn it back on and go into settings and uncheck ""Xbox turn off" turns off my cable or satellite box"", then switch the previous setting back to Instant-On

It is a work around but the only down side is you will have to turn your cable/satellite box off until/if they get a fix

If you have the console set for instant on mode, turning the console off will put it into standby mode. You would have to turn it completely off by holding the power button down on the console.

If it's not on instant on mode, then turning it off via the controller or settings would turn it completely off.

Have you changed the power mode of you xbox so that when you turn it off it is actually turning off, and not going into "instant on" mode?

If it's set to "instant on" mode you can alternatively just hold the power button down on the front of the console for 5 seconds to completely shut down your xbox.

Here is a guide to the power settings, the different modes and how to change them

Yes, the light stays white in "Instant On", and turns yellow if you turn completely off. Ive had mine in instant on since launch, so that updates will come down automatically.

Yes there is the "Instant-On" mode which gives quicker startup time and will let the console download system updates and apply them when they become available..

When you have set the consoles Power mode to "Instant" on you just turn it off like before and it will enter Instant off mode instead of turning completely off
