>>713705484I noticed that Nintendo put a rubber cover inside the analog stick to trap particles and dust, which confirms my theory that all premature drift is caused by microscopic particles entering the potentiometer. If this cover works, it is possible that drift cases will take a few years to start appearing (this is inevitable, however).
My last controllers didn't last more than a few months before drifting, but my DualSense has been going for over a year, and the only difference is that I keep it in a plastic case when I'm not using it, which considerably reduces the dust that settles on the surfaces and then enters the potentiometer with normal analog stick movements.
