The apps basically read a file location in some system level directory and the file is from samsung
i didn't compare if the numbers match the real charging experience but your observation of inconsistent reading can be due to the way the connection is made from cable to phone and cable to charger (for the same charger & cable)
and current value is directly affected by the resistance of the cable
Those who studied physics will know the simple law
V = IR (V = voltage, I = current, R = resistance)
Since V is always constant (assuming your charger is stable), then an increase of R will decrease I and vice versa
And R (resistance) is affected by
1) copper wire length
2) copper wire width
3) copper wire material quality

So in short, you need to find the right combo of charger + cable to get highest GCC value
I do agree with you but the voltage abd current that go into the wall socket also should take an account. Cables from main distribution board to our wall socket does degrade though.i didn't compare if the numbers match the real charging experience but your observation of inconsistent reading can be due to the way the connection is made from cable to phone and cable to charger (for the same charger & cable)
