Incorrect Power Consumption Values

[ThelloD]

Some of the reported power consumption values are implausible. All tests were performed while running on battery only.

Example 1: Sum of power metrics approx. 2.5 times the reported system total power consumption.
I ran a LLM using OLLAMA, as expected the total power consumption spiked. The total system power consumption as well as the battery output was around 67W, so that seems to match.

However, the power consumption of some components are way off:

• GPU: 140W
• RAM: 31W
• CPU: 4W (should be fine)

The sum of those three components is 175W, which can't be correct if the total consumption is around 67W.

Example 2: Incorrect graph for DC in
My device was not connected to an outlet for >24 hours. The displayed value for DC in (0.00 W) is therefore correct, however the graph doesn't seem to match that value (which should be constant), but rather is related to the battery output or system total consumption.

If you hover over the graph, even the spikes are reported as "0.0W". Not sure what is going on here, maybe it's just a measuring inaccuracy, and the actual value of the spike is something like 0.03W, but since those small values are used as the maximum, the graph is scaled to look like power is coming in? But that is just a guess for now.
