powerstat
Powerstat measures the power consumption of a machine using the battery stats or the Intel RAPL interface. The output is like vmstat but also shows power consumption statistics. At the end of a run, powerstat will calculate the average, standard deviation and min/max of the gathered data.

InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
I'd recommend installing powerstat to test your power usage more reliably. Give it a try with it running "idle" on KDE and on sway - I bet it'll improve w/ the latter. The 12th gen CPUs seem to be extremely sensitive to near idle power usage.
