If you’re like most people, you probably have a PS4 controller lying around somewhere. But if you don’t want to use it anymore, there are a few ways to do it. The first way is to take it apart and clean the contacts. This will help reduce the chances of getting something stuck in the controller and causing problems down the road. The second way is to simply disconnect the power cord and remove the battery. This will free up the controller so you can use it again.
