As the title says: What is the maximum charging current supported by Samsung Galaxy S3 (GT-I9300)?
I could not get my fully depleted battery to charge over 450 at first, but once it had some charge, it was up to 1200 by end of the cycle (average) with a peak of 1800. I then hit reset and it dropped to 540 (battery at 100%).
I can only assume the battery itself then, dependimg on its level of charge, will draw at a variable rate.
Current is drawn from the load, not pushed from the source (voltage does the pushing).
The wall charger contains only a power supply. The actual charging circuit is in the phone and it's a fairly smart one. It limits the amount of current the battery can draw regardless of the current available whether 1 amp, 2 amps or 200 amps.
