The charging current is ~9A. when stop charging, smartphone is at standby mode and consume a few mA current, battery A charge Battery B with ~140mA current. 25 minutes later, two batteries are balanced which means no charging current, the remain capacity i 81% for battery A, and 76% for battery B. 50 minutes later, the remain capacity is 81% for battery A , 80% for batteryB, which means battery A remain capacity is same as before, while battery B remain capacity increase 4%! could
