It seems there is a bug in kinfocenter.
When I click on Energy information in Kinfocenter I get the following message:
This type of history is currently not available for your device.
This happens as well on the live-usb-version as well on the installed version
Some digging on the internet gave me this link.
It seems that the bug is there for years now and still not solved. I have tested this on Kubuntu, KAOS, and PCLinuxOS KDE edition
