If the charger is left connected to the battery, a periodic ''top up'' charge is applied to counteract battery self discharge. The top-up charge is typically initiated when the open-circuit voltage of the battery drops to less than 3.9 to 4 V, and terminates when the full-charge voltage of 4.1 to 4.2 V is again attained.
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.
