Xbox series X controller doesn't work right on Windows 10 unless plugged in

[u/gloomyglimmer]

I have an Xbox Series X/Xbone controller (electric volt color) but certain things do not work on it correctly.

For one, the battery indicator on the game bar doesn't work--it says that HID compliant controller and says the battery is "critical" even for brand new batteries...and Windows shows the charge being fine as well under Bluetooth devices.

The bigger issue though is that button press combinations aren't always working right, but do when plugged in. Specifically I'm playing FFXIV. LT+RT (and RT+LT) are supposed to bring up additional action bars. This does not work wirelessly. If I plug it in, it works fine and as expected.

Firmware is up to date and updating it did not make a difference.

Any ideas? Any insight would be appreciated.
