Way off power estimation Intel AX201 Bluetooth, with HID devices active

[shoffmeister]

Running powertop 2.14 on Fedora 36 (kernel 5.19.4-200) while on AC, and with two Bluetooth devices connected, I get

Power est.              Usage       Events/s    Category       Description
  49.3 W     94.7%                      Device         USB device: usb-device-8087-0026
  5.79 W    100.0%                      Device         Radio device: btusb

This data does not make any sense.

The USB device is

Bus 003 Device 004: ID 8087:0026 Intel Corp. AX201 Bluetooth

which is a "Intel® Integrated Connectivity (CNVi)" piece, with what I would call "cost optimizations" in place to utilize main CPU capacity for handling Bluetooth and WiFi.

Connected are two Bluetooth input devices

• Logitech MX Keys Mini
• Logitech MX Master 3S

It would seem as if any activity on the Bluetooth devices - i.e. typing on the keyboard, or wiggling the mouse - causes the power estimate to skyrocket.

System is a Dell Inspiron 7610 (with Nvidia RTX 3060).

hi @shoffmeister the power estimate feature has been disabled because of the known issues.

Interesting. Can you please reference the commit disabling the feature?
