1. A method for processing power management in a mobile device designed to be powered by a battery, said method comprising:

  • providing user input means for receiving user input specifying an operating time desired by said user for said mobile device to maintain sufficient battery life for a continued operation of said mobile device during said operating time;

    monitoring battery charge level of said battery;

    determining battery charge usage level of said mobile device;

    determining projected operating time of said mobile device if said mobile device continues to operate at said battery charge usage level;

    determining if said battery charge level is sufficient to maintain operation of said mobile device during said operating time if said mobile device continues to operate at said battery charge usage level;

    continuously determining a current battery charge usage level and a current battery charge level, said method further including continuously determining if said current battery charge level is sufficient to maintain operation of said mobile device during said operating time if said mobile device continues to operate at said current battery charge usage level;

    notifying said user when it is determined that it is impossible to maintain operation of said mobile device during said operating time if said mobile device continues to operate at said current battery charge usage level;

    determining which applications are running on said mobile device;

    displaying a priority power-down schedule to said user for enabling said user to input a priority level to each application running on said mobile device; and

    using said power-down schedule by said mobile device to power-down one or more of said applications when it is determined that it is impossible to maintain operation of said mobile device during said operating time if said mobile device continues to operate at said current battery charge usage level, said mobile device being operable to continue to power-down said applications until said mobile device is determined to be able to operate for said operating time.
