Xbox elite series 2 disconnects from pc periodically

Is it a game that supports controller use? if not, i would recommend looking into a xim adapter.

To ensure your satisfaction, we're extending the warranty coverage period on Elite Series 2 controllers from 90 days to 1 year from the date of purchase. This extension applies retroactively for Elite Series 2 controllers sold to date.

It definitely should have been a year. From late 2020:

That still applies far as I know.

Ive had the baseline controllers for years and keep holding back from pulling the trigger (get it?) for an elite controller. When the series 2 came out, I was ready to go get one, but the fervor died off with reports of disconnecting.

Right now I’m still waiting to get an elite. I plan on it sometime this year, maybe with the Series X

There was a new update released, can you try updating your Elite Series 2 controller again?

I also have the Elite Series 2 controller and I do not run into these issues when using it with the PC.
