Just generically to the Dev team who have initially responded. I don’t encounter this issue in a Pixhawk Mini using the v3 1.8.1Dev stack. I’m no expert nor coder and can only surmise something changed between those versions.
Thanks.
I’d add a PX4 GitHub Issue with details on a telemetry log. And then post a link to it in slack. Not sure how many PX4 devs are seeing this since this is a QGC forum.
Opened and posted issue as recommended in https://github.com/PX4/Firmware/issues/12255
Thanks.

Hello, I am facing the same issue. The QGCS does not show the real-time battery status of the drone. Does anyone know how to solve this issue?
