KDE High Number of Wakeups

I've noticed that my laptop gets a high number of wakeups/second and the CPU hardly reaches sleep state. I thought values above 1000 were normal on idle until I researched that people get within 100-300. I suspect it's mostly KDE related according powertop. I have disabled animations and other effects. But wakeups still remain high, wakeups dropped from 1500 to 1000. I  notice that powertop is still finding wakeups from plasmashell and kwin. Any further suggestions?

Re: KDE High Number of Wakeups

There're quite some input events and I assume telegram might update its systray icon which will wake plasmashell (to repaint the icon) and in turn kwin_x11 (assuming you did not stop the compositor, but "only" disabled fancy trasition events)?

Re: KDE High Number of Wakeups

Switched off composer and waited for a day, to find a difference. Wakeups still high around 900-1200 on average sometimes drops to 570 for a short time

Re: KDE High Number of Wakeups

Try to kill telegram.
The only other thing are the input interrupts. Do you only have a touchpad or also a mouse? Can you toggle the touchpad off (many notebooks have a function key to HW disable it)?
