A method, programmed medium and system are disclosed which provide for user-controlled management of power requirements for mobile devices. The system enables the user to determine and adjust power settings according to time-related goals set by the end user. The end user, in one example, may specify a goal in hours, minutes or a predetermined date/time and the power management function displays, for example, various combinations of power-down options on specific system devices which can be implemented to achieve power availability for the specified amount of time. The user is enabled to select which of the displayed combination power-down option schemes to implement in order to best suit the user's application requirements during the time frame in which the power-saving scheme will be implemented in order to maximize power-saving while still providing optimum functionality for the user's particular application.
