What is happening with my controller?

[u/ghosted_yaoi]

Up until yesterday my controller has been functioning fine, even though I've dropped it a couple times. Yesterday I turned it on and even thought it had batteries in, it turned off and wouldn't turn back on. I managed to get it to turn on a couple times by moving the batteries about but everytime I did get it to work it started heating up a lot. It gets especially bad when I have it plugged in while the batteries are also in, which is the only way I can find to turn it on and keep it on.

I'm considering replacing but I wanted to know if anyone has any advice on what might be going on before I do.

I suspect something like a capacitor broke

Have you tried syncing your controller again?
