Energy consumption of battery
SUMMARY
Power vs time graph in System Settings --> Energy shows incorrect power values
for period of no usage. My case: Battery was decharging, power was roughly 10
W. Power increased to 20 W by increased load (watching videos). Battery is
faulty and dropped suddenly from 50% to 5% and laptop switched to other
battery. The faulty battery wasn't in use for 40 minutes. Thus, the power in
this interval was 0 W. Then the laptop was attached to power again and charging
of both batteries set in. Charging is now represented by 20 W power. The values
from the last discharge (20 W) and the insetting charge (20W) were simply
connected. This implies a wrong interpretation of constant load of 20 W. But
the battery wasn#T in use, it should be showing 0 W.
Parallel problem: Discharge and Charge are represented by power of the same
sign. If discharge is represented by positive power, charge should be
represented by a negative charge. Or maybe different colors could be used. It
is hard to distinguish between charge and discharge in the graphs.
Please have a look at the attached screenshot.
STEPS TO REPRODUCE
Switch between discharging and charging and look at the power consumption.
OBSERVED RESULT
Power consumption between end of discharge and begin of charge is connected by
a line and thus simulates a constant power load.
EXPECTED RESULT
Empty or unloaded Battery should show 0 W for this time period.
