SUMMARY At some random point, the Event viewer starts being flooded with messages from igccservice (an Intel Graphics service) and HPSupportSolutionsFrameworkService, with more than 100 messages per second, those saying "PowerEvent handled succesfully by the service.". After investigating for a while, I discovered that as soon as I quit KDE Connect, the messages stop coming and the computer acts normally again, the CPU usage drops down to normal and temperatures go from 70/80°C to 45/50°C again in idle. STEPS TO REPRODUCE 1. None at all, just wait for it to happen 2. 3. OBSERVED RESULT CPU usage stays at 10+% and temperatures goes 20+°C higher than normal temps, all while idling EXPECTED RESULT Computer behaving normally while idling SOFTWARE/OS VERSIONS Windows: 11 22000.282 macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION It does this on Windows 10 too
There's an still unknown bug in the battery plugin that causes this. As a workaround, can you try disabling the plugin and see if the issue disappears?

We disabled the problematic plugin so recent builds should be fine. However it seems that you need to uninstall the old version first, otherwise the problematic file isn't removed
I have had this bug for around 6 months now and until now I couldn't figure out what caused it. I almost bought a new charger because it only happens while plugged in to AC power. Today I finally found this reddit post [1] saying KDE Connect is the cause -- and indeed it is. The problem immediately stops when I stop KDE Connect. For me, the increased CPU Usage made the system pretty much unusable until rebooting. Oh man, I'm so glad I finally found out what the problem was. I must have spent dozens of hours trying out all sorts of different GPU drivers, because the NVIDIA and Intel driver processes were always the ones with the highest usage. Until recent driver versions, the igccservice didn't even exist or maybe just didn't trigger the PowerEvent event log entries, so I did not even have that clue. > We disabled the problematic plugin so recent builds should be fine.

So this doesn't seem to work for me? [1] https://www.reddit.com/r/HPOmen/comments/qgd2wm/igccservice_making_my_laptop_go_crazy/
I'm obviously biased, but I feel like there might be other people in my situation who are tearing their hair out trying to figure out why random processes are using so much CPU for no apparent reason. It would be nice if there was some way to detect this bug and at least notify affected users that it is KDE Connect causing it. I like to think I'm usually good at tracking down problems like this, but this one was tough to figure out, because none of the clues point towards KDE Connect, as far as I know. If you need any help debugging this, I'll try to assist any way I can.

I noticed that while this bug is happening, in the Windows lock screen, the battery/power icon in the bottom right is flickering a lot. Probably at the same frequency as the PowerEvent log entries. It sometimes affects the battery tray icon as well, but less often IIRC.
The store version has now been updated
(In reply to Nicolas Fella from comment #8) > The store version has now been updated I can confirm that disabling the battery plugin prevents the issue. I can also confirm that the new Store version has fully removed the battery plugin.
