1. A method for monitoring a battery of an electronic device, the method comprising:

  • monitoring a voltage of a battery powering an electronic device, the electronic device having a brownout voltage;

    reducing power drawn by the electronic device, in event a first criteria is satisfied, the first criteria comprising whether one or more first transient voltage-dips below a predetermined threshold voltage are measured; and

    further reducing power drawn by the electronic device in event a second criteria is satisfied, the second criteria comprising at least one of whether a frequency of transient voltage-dips below the predetermined threshold voltage exceeds a predetermined frequency, whether a number of transient voltage-dips below the predetermined threshold voltage exceeds a predetermined number, or whether a duration of at least one transient voltage-dip below the predetermined threshold voltage exceeds a predetermined duration,wherein the predetermined threshold voltage is greater than the brownout voltage of the electronic device.
