Controllers keep flashing

as a side note I have tried and synced the controller but the controller's lights keep flashing so it never syncs with the xbox.

nat settings are open. that was the first thing i checked on it.

for the battery, even regular batteries make the lights flash like that. as i said i switched controllers and it didnt keep flashing like that. another charge cable does same thing. another battery makes it keep flashing.

hey thanks for the help I tried turning it on manual and the controller sync but after that it won't sync anymore and the lights keep on flashing on the controller. when I try to go sync it with the 360 but the 360 doesn't pick it up and the lights still
flash on the controller. what does this also mean?

when i attempt to synchronize the controller to the Xbox, the synchronization stops as if they had finnished syncronising, but the controller keeps flashing its lights as if trying to connect

Hello!

Thanks for reaching out to us here on the forums with this situation. I understand you're having trouble with a couple of controllers staying synced to the console. Take a look at the steps listed in this support article:

Troubleshoot your Xbox One wireless controller. If those steps don't resolve the situation. Try safely powering down the console and then unplugging it from its power source completely. Leave it unplugged for about 2 minutes or so. After the time has passed
remove the batteries from the controller and connect it with a working USB cable to the console. Then use the controller itself to power up the console by holding the Xbox Guide button (light up Xbox logo). If it starts up try replacing the batteries and unplugging
the USB once you're at the home screen. Give it a try and let us know with a reply if this helped.
