Topology and method for dynamic charging current allocation

An electronic device comprising:

• a load;
• a battery for powering said load;
• an adapter for charging said battery;
• a charger controller operable for controlling a charging current of said battery according to a status of said load, wherein a first charging current is selected when said load is off, and wherein a second charging current that is less than said first charging current is selected when said load is on;
• and
• a counter coupled to said charger controller operable for determining a charging time according to said status, wherein a frequency of said counter is set to a first frequency when said load is off, and wherein said frequency is set to a second frequency that is less than said first frequency when said load is on.
