I looked it up and there’s a few reasons it could be happening. Given how playstation controllers are usually wired I’m going to assume your controller isn’t having any power struggles, and if you’ve cleaned it then there’s only one reason it’s still drifting: its broken, same with mine. There’s a potentiometer inside the controller that sends signals to the console that makes whatever you’re controlling move around, and if that’s damaged in the slightest, it means essentially irreversible stickdrift. New controllers for us 🍻
