When I turn my controller on, how is that my Xbox can turn on?
And why is it that I can’t remotely turn it on through the Xbox app when its power mode is set to shutdown?
In: Technology
Inside the xBox, there are circuits that always use power. When you push the button, that doesn’t turn on the power, it makes a signal to this always on circuit, and if conditions are right the xBox power is turned on. The app likely communicates over the network, and the network stuff isn’t always on because radios use a lot of power.
Your Xbox isn’t truly ‘Off’ unless you’ve unplugged it or turned it off at the wall.
It’d be more accurate to say it’s in ‘Standby’. It’s in a dormant low-power state, but as long as it has power there’s a circuit in there that’s constantly running waiting to detect the power-on signal from the controller. When it detects that, it sends a signal to the Xbox to power on.
If your Xbox was truly ‘off’ that wouldn’t work as the circuit that detects the power on signal from the controller would be offline, and thus unable to detect the signal from the controller. This principal applies to anything that can be powered on remotely – TV’s Smart lights, Sensor activated doors, if it’s awaiting a signal to turn on it’s never truly ‘off’ until the power to it is cut.
Modern electronics basically never shut down completely. When you “turn them off” they will go into a low-power standby mode but retain enough functionality to listen for the power-on signal. They only shut down when you physically disconnect power by pulling the plug or let the battery run dry.
