There is a charge controller chip inside the phone that determines how much current to put into the battery. Generally lithium ion batteries are charged with a constant current until the cell voltage reaches a specific level, at which point the charge controller switches over to constant voltage charging until the current drawn by the cell decreases to zero.

How To Control Voltage/Current
