Using the BTA30 pro and Qudelix as well and my experience has been very similar. When connected via LDAC, it's almost always in 660kbps mode (as reported by the Qudelix app), so I'm currently experimenting with Aptx HD instead since it's often reported to use less battery.
edit: should note that my BTA30 pro is connected to a picoreplayer setup in case it's helpful to anyone else.
