Abstract
Systems (100) and methods (600) for recharging a battery (292) of an electronic device (102) which has been placed in a cradle (106) of a charging dock (104). The methods involve: measuring a charging voltage value and a charging current value for the electronic device; determining a first value of angular orientation for a current position of the electronic device relative to a reference angular orientation of the electronic device; selecting at least one first indicator from a plurality of indicators based on the charging voltage value, the charging current value, and the first value of angular orientation; and outputting a first indicator to the user of the electronic device.
