Methods, apparatus, systems, and articles of manufacture for a battery charging device are disclosed. Example battery charging devices include a temperature sensor to sense a skin temperature of an electronic device in which the battery is installed, and a current controller to control a magnitude of a charging current to be supplied to the battery. The current controller causes the magnitude of the charging current to oscillate between an upper level and a lower level and a current adjuster adjusts the upper level downwards and the lower level upwards based on the skin temperature sensed by the temperature sensor. In some examples, a memory device stores a thermal set point and a comparator compares the skin temperature to the thermal set point and transmits a control signal to the current adjuster based on the comparison of the thermal set point to the skin temperature.
