Abstract
A method and apparatus for monitoring battery life in a human input device powered by replaceable batteries includes repeatedly measuring battery charge by use of a measuring arrangement forming part of the input device. Battery charge is measured while the input device is in a relatively inactive condition and when it is in an active condition, and a time value is associated with each battery charge measurement. A usage model may be constructed based on the battery charge measurements, and calculation of an expected battery life may be based at least in part on the usage model.
