Support for specific buttons and features, such as a controller's audio jack or lights, varies by controller and the app you're using with it.

(if present) next to its name, then select Forget This Device. Connect the controller again. - Reduce the number of Bluetooth devices connected to your Apple device. This can also help with connection issues related to wireless interference.

The limit for other Apple devices varies based on your specific setup and wireless environment.
- To charge your controller, use the charging solution included with your controller or recommended by the controller manufacturer."
