Intel 7260 bluetooth device (usb-device-8087-07dc) at 100% energy usage

Hi,

I posted this the other day in http://askubuntu.com/questions/79734...c-at-100-usage, but did not get a solution. So, I am posting it here as well, in case anyone can lend a hand.

My Intel 7260 bluetooth device is constanly draining battery. As per powertop:

13.9 W 100.0% Device USB device: usb-device-8087-07dc

I have both bluetooth and NFC disabled in /etc/rc.local:

rfkill block bluetooth
rfkill block nfc

And the suspend options are set as "Good" in powertop:

/sys/bus/usb/devices/3-9/power/autosuspend = 2
/sys/bus/usb/devices/3-9/power/autosuspend_delay_ms = 2000
/sys/bus/usb/devices/3-9/power/control = auto

I am using Ubuntu 16.04, keel 4.4.0-28.

This device did not use to use so much energy before. This behaviour has only started in the last one or two months.

I have tested with a live USB Ubuntu 16.04 image and the issue does not occur in there. So, it does not seem to be a hardware issue, but a software/configuration issue.

Also, I have another computer (with the same hardware), also with Ubuntu 16.04 and keel 4.4.0-28, which is not showing this issue.

I have tried everything I can think of: disabling bluetooth in the bluetooth applet, going back from GNOME 3.20 to GNOME 3.18 just in case, uninstalling the Nvidia proprietary driver, and disabling the wifi.

How can I get this device to stop using power at 100%?
