Hello,
No I did not actually check powertop, probably should have.
I have never actually used powertop, for as far as I can remember, I have taken a look at the manpage and the ArchWiki page, and the following seems to have the highest events (so I assume the highest power use?), see the top 3 below (in order):
- tick_sched_timer - HI_SOFTIRQ - i915
So third place is the driver for the integrated intel graphics, so I assume it was a valid assumption that the graphics is one of the major power draws.
Is there something specific you are looking for from powertop,
IIUC you are looking at the "Overview" pane, and your top 3 basically says your system is idle. My system does not show HI_SOFTIRQ here, no idea which part it corresponds to... Anyway integrated GPU usually does not draw a lot of power. Maybe check "Idle stats" and "Frequency stats" to be sure your CPU is actually put to sleep; on my i5-12400 the cores are >99% in C10, frequency <800MHz. Also check "Device stats" just in case; I have seen SD card readers constantly consuming power without cards inserted.
