Xbox elite series 2 drop outs on pc?

I got my Series X in January, and never even took the included controller out of the box, because I own the Elite Series 2. When I dropped my Elite Series 2 (oof) recently, I sent it off for out-of-warranty repair, and pulled out the basic controller, still wrapped and taped in the foam bag in the box.

Stock controller worked fine for a few days, then there was a firmware update - recently, and I'm having intermittent disconnections all the time. It works fine when wired with a USB-A -> USB-C cable (I use the 9-foot one that comes with the Elite Series 2).

I decided, since I'd never had trouble with connectivity on the Elite Series 2, that I would buy a 2nd one, brand new of course. It 100% required me to update before proceeding.

Since I never had issues with the Series X and Elite Series 2, I wasn't aware of the known connectivity issues until the basic controller started intermittently dropping connection.. After searching, I saw that there were a ton of articles from way back in January, including Microsoft acknowledging the problem and releasing a firmware update in March...

Yet here I am with a freshly unwrapped Series X controller AND a brand new, (delivered Sept. 7th) SECOND $180 Elite Series 2 controller, and BOTH are cutting out intermittently..

-Sitting Less than 7 feet from my console

-I keep my batteries charged - both the Elite's internal, and the Enelooph Pro AA rechargeables that I use in the regular controller.

-As I mentioned, latest firmware on controller

-Of course, latest firmware/software on Series X console

-Both controllers work fine when wired.

-Already performed hard power cycle on the controller as well as the console.

-1st Elite (the one being repaired) never had issues until I dropped it - but it was never exposed to that new firmware)

-That's 8 months I used my 1st Elite Series 2 with the Series X and no problems.

It seems to me that the original intermittent connectivity issues were never resolved.

no don't buy an elite series 2 because ive had 2 brand new elite series 2 and they where both broken out of the box

My elite series 2 works just fine the first time I pair it to the PC. However after that it experiences the problems described with the frame rate drop etc or won't connect to the pc at all. If I remove the device and re pair it it works again over bluetooth
until the problem crops up again..

Turns out, the Xbox Elite Series 2 controller needed to be replaced.

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.
