After three weeks of owning the console, we noticed we were going through batteries like crazy. Up until this point, the only game I had an issue with in terms of controller connection was in AC4, where ever so often the game would say the controller wasn't connected. With the official play and charge kit, the controller becomes completely unresponsive. The explorer button will work, and it will allow me to move between items, but once back in the home screen nothing. I've looked through several pages here, and most of the disconnect issues seem to be with the day one edition. I have a standard edition X1. Is this the controller or is this the battery pack?
