<p>A method (200) for power management , the method includes supplying (240) power to at least one component of a mobile device. The method is characterized by autonomously detecting (210) power sources capabilities selecting a (220) power source in response to the detected capabilities and to at least one power source selection rule; and applying (230) a power regulation operation on the power to be supplied to at least one component of the mobile device. A mobile device (100) having power management capabilities, the mobile device includes at least one component (190) that is powered by a supply voltage. The mobile device is characterized by including a power management circuit (190) that is adapted to: (i) autonomously detect power sources capabilities, (ii) select a power source in response to the detected capabilities and to at least one power source selection rule; and (iii) perform at least one regulation operation on the power to be supplied to the at one component (190) of the mobile device.</p>
