was playing around with the Galaxy Charging Current thingy...
noticed the following reading on my bedroom wall socket:
current_now: 1698
current_avg: 700
current_max: 700
i tested with office socket 1 (cable from box):
current_now: 1698
current_avg: 1300
current_max: 1300
i tested with office socket 1 (cable from yoobao -- but mine is a very long one)
current_now: 1698
current_avg: 1800
current_max: 1800
i tested with office socket 2 (cable from box):
current_now: 1698
current_avg: 1200
current_max: 1200
i tested with office socket 1 (cable from box) - 10 minutes later:
current_now: 1698
current_avg: 1000
current_max: 1000
i do wonder how accurate is the reading.... coz i noticed reading can change when you turn off power on the socket and then turn it back on...
or does that mean i have problem with my charger?
700 for home wall socket... meaning my wall socket is lousy?
haiz...
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
Cables are always the last thing people will look at when they want to put the blame on slow charging
