Comment 24 for bug 1801642

For an unknown reason, the TLP setting is not applied after suspend/resume.

The thing I found to work for me is creating a file /lib/systemd/system-sleep/bt_autosuspend with this content, using the exact same line used by powertop (and set it executable) :

#!/bin/sh

# prevent the btusb from suspending after resume

case $1 in
    pre) ;;
    post) echo 'on' > '/sys/bus/usb/devices/1-7/power/control';;
