Also sometimes it will sink and it will show that it's connected but none of my movements will transfer onto the TV as if I'm not even touching the controller

I'm having issues with my controller I can be playing a game and it will randomly unsync and just start randomly blinking I can have the controller plugged into the Xbox with a cord cell phone charger or anything and it's still blinks even on the cord it will turn off my controller still won't sync to the Xbox any help please
