Charge indicator for an energy source
First Claim
1. A charge indicator for an energy source of a mobile communication device comprising:
- apparatus adapted to receive an indication of the magnitude of the present charge of said energy source;
apparatus that uses said indication of said charge magnitude to determine an estimated service life of said present charge for an idle mode of said mobile communication device;
apparatus that uses said indication of said charge magnitude to determine an estimated service life of said present charge for an active mode of said mobile communication device;
apparatus responsive to a determination of an idle mode to provide a visual indication in a time domain of said estimated service life of said present charge of said energy source for said idle mode of said mobile communication device; and
apparatus responsive to a determination of an active mode to provide a visual indication in a time domain of said estimated service life of said present charge of said energy source for said active mode of said mobile communication device.

Abstract
A battery charge indicator for a mobile communication device, such as a cell phone. The battery charge indicator receives an indication of battery power, uses the indication to determine an estimated service life of the present charge of the battery during an idle mode of the mobile communication device, uses the indication of battery power to determine an estimated service life of the present charge of the battery during an active mode of the mobile communication device and control a display element to provide visual indications in a time domain of the estimated service life of the battery charge for the idle and active modes of the mobile communication device.

10. A method of determining an estimated service life of a charge of an energy source, such as a battery, adapted for use in a mobile communication device, said method comprising the steps of:
-
receiving an indication of the magnitude of the present charge of said battery;
receiving information defining at least one characteristic of said battery;
using said indication and said received information to determine an estimated service life of said present charge of said battery for an idle mode of said mobile communication device;
using said indication and said received information to determine an estimated service life of said present charge of said battery for an active mode of said mobile communication device; and
in response to said determinations, providing visual indications in a time domain of said estimated service life of said present charge of said battery for said idle mode and for said active mode of said mobile communication device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
