Comment # 9 on bug 1187195 from Sebastian Turza������ski

I have done more testing 
Fedora 34 power consumption is going as low as low as 3.14 W/h
with the same scenario (cpu idle - below 1%, no gpu, almost idle desktop)
opensuse tumbleweed hits 17 W/h on average.
Ubuntu 20.04 also gets close to Fedore 34


You can say powertop is inaccurate but I can really feel the difference in
laptop heat.

The battery reports a discharge rate of 17.3 W
The energy consumed was 329 J
The estimated remaining time is 3 hours, 50 minutes

Summary: 3145,5 wakeups/second,  0,0 GPU ops/seconds, 0,0 VFS ops/sec and 70,3%
CPU use

Power est.              Usage       Events/s    Category       Description
  11.5 W      5,1%                      Device         Display backlight
  5.85 W     58,5 pkts/s                Device         Network interface:
wlp0s20f3 (iwlwifi)


I can understand it can vary between OSes but this  is huge difference on work
hours in the end I get almost several times more on other Linuxes in comparison
to OpenSuse.

I tried home:tiwai:kernel:5.11 but not much improvement if any
