Public bug reported:
When using powerprofilesctl to manage power profiles energy usage is
much higher than when using tlp.
With powerprofilesctl on the power saver profile it runs at around 21W - 24W
where as on tlp it
can be between 8W - 11W while streaming a movie say.
Energy rate was checked using upower:
```
upower -i /org/freedesktop/UPower/devices/battery_BAT0
```
```
...
energy-rate: 9.8163 W
...
```
Expected behaviour:
Battery last a reasonable amount of time when on power save profile.
Actual behaviour:
Battery drains much faster on powerprofilesctl on the power save profile.
There is no noticeable speed/performance difference when on tlp compared
to powerprofilesctl.
This is on a Dell XPS 9530 with ubuntu 26.04, Linux 7.0.0-29-generic.
Observed same behaviour on previous ubuntu version using powerprofilesctl (
power-profiles-daemon (Version: 0.30-2)).
Can the power save profile be improved to preserve energy a bit more,
this will help non technical to users preserve energy and save battery
cycles.
