Xbox elite 1 on series x, firmware update?

i have the standard issue for xbox one x an elite series 1 and an elite series 2 and i can honestly say the elite series are worth the money

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.

Same here, the exact same problem on my XBOX series X and S....

from 6 joysticks I have, only 2, elite 1 and and old xbox one s controller, without updated firmware, are working fine.

but all my fancy new Xbox series controllers are having this problem since past year and I was thinking the problem were my controller battery (I have the official charge and play battery on all my controllers)

hopefully they will address this soon...

I just updated the firmware prior to posting. It is on the latest version. It did not fix the issue. I am on Xbox series x

Firmware version 517.3202.0 is the latest firmware version available for the Elite Series 2 controller. So your controller has the latest firmware available.

Don't forget the Elite Series controllers use a different firmware than the other controllers, because it has different features to the standard controllers.
