ABSTRACT:
By determining charging current Icharand then subsequently utilising that determination of charging current Icharin relation to battery current Ibatand load current Iloadas a result of operation of a phone or other electronic device it is possible periodically to adjust the necessary charging current in order to operate the device in terms of recharging the battery to a target charging voltage, as well as providing adequate electrical current for operation of the associated phone or other electronic device.
