This was archlinux package bug
Comment 2 Dominik K. 2023-07-11 16:03:06 UTC 
I dont't think it is an archlinux package bug, because it also effects powerdevil 5.27.6-1 and 5.27.6-3 on the Steam Deck.

Here is my terminal output:
org.kde.powerdevil: KDE Power Management System init failed!
org.kde.powerdevil: org.kde.powerdevil.chargethresholdhelper.getthreshold failed "Charge thresholds are not supported by the kernel for this hardware"

With version 5.27.5-3 everything works fine. However there was the hint "Charge thresholds are not supported by the kernel for this hardware" too. But powerdevil starts and I am able to see the battery and brightness widget an set the standby timings in the KDE settings, which is not possible with powerdevil 5.27.6-1, 5.27.6-2 or 5.27.6-3.
Comment 3 Dominik K. 2023-07-11 16:05:30 UTC 
Maybe it only effects just specific types of hardware like MSI Modern 15 B12M and the Valve's Steam Deck?

Please file a new report. This was caused by a missing dependency downstream.
