  • a battery;

    a battery gauge;

    a display;

    storage;

    an input/output subsystem;

    one or more processors; and

    memory containing instructions executable by the one or more processors whereby the device is operable to;

    determine if the battery is discharging;

    monitor, in response to determining that the battery is discharging, one or more parameters associated with the battery during discharge to detect discharge events;

    determine a minimum capacity and a maximum capacity of the battery in response to the detection of the discharge events measured by the battery gauge;

    determine a first count of minimum capacity of the battery and a second count of maximum capacity of battery based upon the discharge events;

    store, in the storage, information relating to the battery'"'"'s state of health including the determined capacity and count information based upon the discharge events;

    determine a state of health of the battery based, at least in part, upon the stored information, the state of health being a measurement of an available discharge capacity in the battery compared to a discharge capacity needed for a workflow executed by a user of the device; and

    display, on the display, an indication of the determined state of health.
