1. A method for monitoring battery life in a battery-powered input device for a processing system, the method comprising the acts of:

  • repeatedly measuring a charge of one or more batteries removably and replaceably received in the device to generate a series of battery charge measurements, the measuring being performed by a measuring arrangement forming part of the input device;

    recording a time value associated with each battery charge measurement in the series of battery charge measurements;

    constructing a usage model based on the series of battery charge measurements and the associated time values; and

    calculating an expected battery life based upon, at least, the series of battery charge measurements and the associated time values.
