If you've tried everything that's listed in http://support.xbox.com/en-us/xbox-one/accessories/wireless-controller-disconnects and still can't seem to make your Xbox One Controller stay sync-ed to your console you might want to give this a try
I tried it and it seems to have worked wonders! Xbox One now wakes 100% from the controller, I have zero sync issues between controller and console. The support call lady told me this is a pretty reliable fix so I don't understand why they don't listed it in their troubleshooting page. I have no idea how common this issue is as I did research for quite a while before deciding to contact Microsoft. Maybe it's just me!
- Disable Instant-On mode.
- Turn off console by holding onto the power button (the Xbox logo) in the front until the console shuts down completely.
- Pull the power cable from the rear.
- Wait over a minute.
- Plug in the power cable and power on the console again. Re-sync the controller to the console as necessary.
