Public bug reported:
when I watch a video in fullscreen, my laptop can draw as many as 25w.
For comparaison, on windows 11, a similar video will take only 8w from
the battery. obviously, the cpu temps and fan speed are much higher on
ubuntu tan on windows. Also, this might be unrelated, but when I plug in
or unplug the charger on my laptop, the power draw reported takes time
to climb up to the actual power draw/ charge rate ( up to 45 sec). In
this vase, my laptop can think that it still has a couple of days left
worth of battery life left
