The controller may work normally and then suddenly lose connection, sometimes showing the controller connection screen or requiring the Joy-Con to be reconnected. The problem can happen even when the controller is charged.

What usually causes this wireless interference, outdated controller firmware, dirty contacts, worn Joy-Con rails, or a hardware problem? What fixed yours?

The analog stick appears centered, but the controller still registers movement even when it isn't being touched. Sometimes the drift is minor, while other times it makes games difficult to play.

Is this usually caused by dirt around the analog stick, calibration, controller software, or worn joystick components? Has anyone found a fix that actually lasts?

Other devices on the same network stay connected, but the PS5 loses its internet connection and sometimes needs to reconnect before the game will work again. What could cause this, and has anyone found a reliable fix?
