Xbox controllers de syncs when Turing xbox off by a controller.

hi SnackPack83

unfortunately you cannot, the controller is set to ''always'' connect to the last synced device.

you will have to sync your controller every time you want to switch device

and turning off the controller by pressing and holding the Xbox button until it turn off is the intended way of turning it off without turning the Xbox off (when synced to an Xbox), or when synced to another device other then the Xbox

For now, why not just turn off the Xbox at the wall, then sync your controller to your PC, then turn the Xbox back on at the wall. That way you wont turn the Xbox One on when syncing the controller to the PC.

Hi, power the xbox and controller on, then press and hold the power button on the xbox for 10 seconds.

When the xbox powers off pull the power cord out of the back of the xbox and wait two minutes. Reconnect the power cord and press the power button on the xbox to power it on. Power on the controller and then try using the controller to power on/off the xbox.

This solution worked. Thank you!

For anyone else reading having this issue, I still had to re-sync the controller after going through the above process, in order to solve that problem. After turning on the Xbox one with the power button sync it the normal way by hitting the sync button
on the front of the Xbox One S, and then holding the sync button on top of the controller. Thereafter, the guide button on the controller will power on the console.

However, the above solution did immediately fix the fact that the controller wouldn't turn off when I powered the console off.

Sync the Controller:
To sync a wireless controller with your Xbox, follow these steps:

Press the Xbox button on the controller to turn it on.
Press and hold the small sync button on the front of the Xbox Series X console (located near the USB port).
While holding the sync button on the console, press and hold the sync button on the controller (located on the top near the Xbox button).
Release both sync buttons when the controller's Xbox button starts flashing. The controller should now be synced with the console.

Have you also tried re-syncing the controller to the Xbox by plugging it in via a USB cable to the Xbox? I do this method to re-sync my controller to the Xbox and it works fine for me. Make sure the controller is off, plug it into the Xbox, then turn it
on. It will flash a few times and will then be synced and you can unplug it.
