WiFi power usage always reported high no matter what I do
etoimene opened this issue · comments
Power est. Usage Events/s Category Description 9.01 W 12,7 pkts/s Device Network interface: wlp2s0 (iwlwifi)
is what powertop reports.
I tried
:~$ sudo modprobe -r iwlwifi :~$ sudo modprobe iwlwifi power_save=y power_level=1
but no matter which level I chose power usage is reported the same and seems excessively high.
Suggestions?
I tried powerstat and seems very low idle. Don't see any big offenders with powertop and htop except network.
sudo powerstat
Running for 300.0 seconds (30 samples at 10.0 second intervals).
Power measurements will start in 180 seconds time.

With Chrome shutdown, average idle 90%. Maybe it's time for a new browser.
