PORTABLE ELECTRONIC DEVICE HAVING LOW BATTERY INDICATION

摘要

A method for determining a battery status of a battery in a portable electronic device includes storing a baseline cycle count in memory of the portable electronic device, the baseline cycle count value being an empirically determined number of actuations that results in a requisite amount of battery depletion to achieve a low battery condition; determining an actual cycle count corresponding to an actual number of actuations of the portable electronic device; comparing the actual cycle count to the baseline cycle count to determine whether the low battery condition exists; and if the low battery condition exists, then notifying a user of the low battery condition.
