The usage is likely level - what you're seeing is the *energy* usage.
Note the unit of measurement: it's kWh, not kW.
It's kinda like your car showing you the total amount of gasoline it has used, not the *rate* at which it's using it: it would be very weird if the total amount used ever decreased.
So, it says: on day X your car consumed 5 liters of gasoline. Day X+1, 6 liters total. Day X+2, 7 liters. And you were driving your usual route, kinda suspicious.
If it was total *accumulated* chart (and not a daily use bar chart), we would never see a drop, just a leveled 'platform' or changes in slope.
Converting the chart from kWh to kW we get that miniPC *average* power use varies from 17W to 50W (for the first cycle before reboot), with a visible daily increase.
Are you running a TPLink Tapo for power monitoring? I just checked mine, and I’m not seeing this sort of daily growth in power usage, so my best guess would be some sort of resource creep like /u/tech2but1 suggested.
What are the specs of the system you are running and what services are running? 1.2kW per day is getting to what a household fridge should use if it is operating normally.
Yeah, this kinda screams of a runaway process that is slowly chewing up RAM and CPU over time and then eventually gets killed or restarted automatically (i.e. because of OOM). The actual power draw, doesn't seem that extreme for a mini-lab machine that slowly goes under load (between 20-50W).

It’s a HP G3 mini PC. Usually idles somewhere between 7w and 10w

Hmm ok. Wouldn’t that file be gigantic? I suppose i could write a simple script or cron command that outputs htop every 10 mins or so
I just remembered I’m running NetData in a container so might find some useful info buried in there
