1. A method performed by an electronic device configured to be powered by a battery, the method comprising:

  • monitoring battery usage habits in using the electronic device, wherein the usage habits include how often the battery is charged;

    predicting remaining usable life of the battery based on the usage habits by approximating an amount by which the battery'"'"'s equivalent series resistance (ESR) has degraded over time; and

    displaying an indication of the remaining usable life of the battery in terms of time, wherein the displaying includes displaying an image that comprises;

    a first representation of an initial capacity of the battery,a second representation of the approximation of the amount of deterioration of battery capacity relative to the first representation,a third representation of remaining capacity of the battery relative to the first representation, anda fourth representation of the remaining usable life of the battery relative to the third representation.
