OK...the other day on Reddit, someone's saying the controller issues in Beat Saber, are due to the battery momentarily losing contact, because swinging so hard is somehow making the battery slide the spring down on it's own, thus momentarily losing contact with the positive contact near the bottom of the handle. I thought this was hogwash...the battery isn't heavy enough to push the spring back, and expert/expert+ mode doesn't mean you're swinging any harder than at normal mode. I suggested tinfoil, but they didn't seem interested. Now...someone else has posted that tinfoil has in fact fixed his issue. Even a youtuber just put out a video, saying it works.
Well, his next video basically proves it's not the battery...he ties the controller to what looks like heavy duty pipe cleaners, then spins it in a circle, with the controller in a position that the battery is actually pushing towards the positive terminal, and not pushing the spring back, as they had originally thought. It does the same thing...at a certain speed, the controller just sticks and spins in mid air.
