I’ve disabled bluetooth at the gnome level, at the systemd level. how do I permanently stop the device itself so I can save power?

systemctl list-unit-files | grep blue

blacklist btusb
blacklist bluetooth

in /etc/modprobe.d/blacklist-mine.conf

Take a look at rfkill command line tool for enabling and disabling wireless devices.

man rfkill
rfkill --output-all

If you are not going to use the thing, might as well not even load the associated modules. We are talking about power saving after all.

well… I killed it, but that didn’t persist across reboots.

… of course not

read the next (and previous) post of @cscs …

that list was insufficient, but I adapted it to the real (full) list of modules. I don’t love this solution since it’s not that friendly if I ever did want to use the hardware (it’s just so rare that I actually do/have, as the only bluetooth devices I have are my phone and a headset)

Who’s fault is this anyways? I feel that there’s a bug here that I turn off bluetooth (including, at IIRC systemd level) and yet it’s still eating power. I’m only assuming that blacklisting the mods makes it stop, I’m not actually certain that it turns the hardware off, vs just making the kernel unaware of the hardware. Of course, I’m also assuming that it can be turned off, or put into a lower power mode.

Then maybe you prefer this method;

(and/or other stuff on that page)

If you still temporary want to use Bluetooth, then i would create me my own .sh file and execute the rfkill command manually and put this file on my desktop.
