Subject: Re: Qualcomm Atheros QCA61x4 keeps drawing 0.85 W despite Bluetooth
being disable in GNOME
[Fix typo in subject line]
Dear Linux folks,
On the Dell XPS 13 9360 from 2016, BIOS 2.21.0 06/02/2022, with Debian
sid/unstable and Debian’s Linux 6.5.10 kernel, I am trying to extend the
run-time with battery, at under 50 % of it’s original capacity, and I am
using PowerTOP 2.15.

Although radio/wireless devices are turned off in GNOME, PowerTOP shows
the Bluetooth device drawing 0.85 W of energy:
848 mW 100.0% Device USB device: usb-device-0cf3-e300

After unloading the module `btusb`, the entry disappears from the
PowerTOP list after a while.
usbcore: deregistering interface driver btusb
Auto-suspend was enabled for the device. (Though it shouldn’t have
mattered as it was disabled in GNOME?)
Anyways, have you heard of such an issue? Can I provide more
information, to get it to not use any energy while being disable in GNOME?
Kind regards,
Paul
