Steam Deck Specific changes:
- Show battery information for connected Bluetooth devices under Settings->Bluetooth and in the Quick Access menu.
- Added a per-device toggle to Settings->Bluetooth that controls whether a device is allowed to wake Steam Deck from sleep.
- Fixed a bug that would cause the UI to show stale data for Bluetooth devices.
Rest of the changelog is here and is mostly desktop client improvements
Maybe try this, in desktop mode make sure the SBC-XQ codec is selected for your headphones, it’s night and day difference for me (or can try LDAC if XQ isn’t available)
