Yup. Only time I ever turn bluetooth on is when I'm using my game controller or the little speaker I move to whatever room I'm in. If it's not being used for either of those things, it stays off. I don't even use it to connect my cell to my computer—that's what usb is for.

Or WiFi. I use KDE Connect to send stuff between my desktop and phone, which works fine.
