Joysticks: Probably Still Drifty
Joy-Con joysticks use a potentiometer to read the voltage at a wiper that slides across a strip of resistive material. That material wears down over time, or plastic and dust can dirty the sensors.
Stick drift is a huge problem with other Switch models. One survey found that 40% of Switch owners had problems with their Joy-Cons drifting, and things didn’t get any better with the Lite or OLED editions. After a bunch of lawsuits, Nintendo’s president even admitted it and apologized, setting up a free repair program for customers in some parts of the world.
Your Gamecube controller also isn’t Hall Effect.
Yeah, I think we should wait and see how prevalent the drifting is this time around before freaking out. Of course it’s going to happen to some people because every stick that uses this technology has some incidence of drifting, but that doesn’t mean it’s going to be as bad as last time. I have lots of these kinds of sticks on lots of gamepads over the years and only the joycons have ever drifted.
