Abstract

A method for determining usage time for a plurality of modes of a mobile device wherein a self learning table within the mobile device includes a plurality of storage locations for storing current usage values and each of the storage locations has an association with a zparticular mode of the terminal. Additional storage locations may be added to the table responsive to new modes of operation of the mobile device,

Claims

1. A method for determining usage time for a plurality of modes of a mobile device, comprising the steps of:

determining a battery current usage value for at least one mode of the mobile device responsive to accessing of the at least one mode by the mobile device;

storing the battery current usage value for the at least one mode in a table at a location associated with the at least one mode, the step of storing the battery current usage value comprising;

determining if the at least one mode has a previously stored battery current usage value;

generating a new location associated with the at least one mode in the table if the at least one mode does not have the previously stored battery current usage value; and

storing the battery current usage value in the generated new location; and

determining the remaining usage time for the at least one mode of the mobile device responsive to the stored battery current usage value at the location associated with the at least one mode.

2. The method of claim 1, wherein the step of storing further comprises the step of replacing the previously stored battery current usage value with the battery current usage value if the at least one mode has the previously stored battery current usage value.

3. The method of claim 1, wherein the step of storing further comprises the step of filtering the battery current usage value prior to replacing the previously stored battery current usage value to limit an amount of change in the battery current usage value.

4. The method of claim 3, wherein the step of filtering comprises the step of averaging the battery current usage value.

5. The method of claim 1, further including the step of displaying an indicator that the mobile device is learning if the at least one mode does not have the previously stored battery current usage value.

6. The method of claim 1, further including the step of preloading a battery current usage value in the table prior to a at least one use of the at least one mode.

7. The method of claim 1, wherein the mobile device comprises a mobile telephone.

8. The method of claim 1, further including the steps of:

displaying a plurality of modes for the mobile device in a menu; and

receiving a selection of the at least one mode of the plurality of modes from the menu.

9. A method for determining usage time for a plurality of modes of a mobile device, comprising the steps of:

determining a current usage value for a at least one mode for the mobile device responsive to accessing of the at least one mode by the mobile device;

determining if the at least one mode has a previously stored current usage value;

generating a new location associated with the at least one mode in the table if the at least one mode does not have the previously stored current usage value;

storing the current usage value in the generated new location;

replacing the previously stored current usage value with the current usage value if the at least one mode has the previously stored current usage value;

filtering the current usage value prior to replacing the previously stored current usage value to limit an amount of change in the current usage value; and

determining the remaining usage time for the at least one mode of the mobile device responsive to the stored current usage value at the location associated with the at least one mode.

10. The method of claim 9, further including the step of displaying an indicator that the mobile device is learning if the at least one mode does not have the previously stored current usage value.

11. The method of claim 9, further including the step of preloading a prestored battery current usage value in the table prior to a first use of the at least one mode.

12. The method of claim 9, wherein the step of filtering comprises the step of averaging the current usage value with the previously stored current usage value.

13. A mobile device, comprising:

first circuitry for determining a battery current usage value for each of a plurality of modes of the mobile device;

a table having a plurality of storage locations therein for storing battery current usage values, each of the storage locations associated with one of the plurality of modes;

a processor configured to store a first battery current usage value in a first storage location associated with at least one mode of the mobile device responsive to accessing of the at least one mode by the mobile device; and

a filter for limiting changes in battery current usage values stored in the table.

14. The mobile device of claim 13, wherein the processor is further configured to determine the remaining usage time for the at least one mode of the mobile device responsive to the stored at least one battery current usage value at the first storage location associated with the at least one mode.

15. The mobile device of claim 14, wherein the filter averages battery current usage values.

16. The mobile device of claim 13, wherein the first circuitry comprises an application specific integrated circuit.

17. The mobile device of claim 13, wherein the processor is further configured to:

determine if the at least one mode has a previously stored battery current usage value;

generate a new location associated with the at least one mode in the table if the at least one mode does not have the previously stored battery current usage value; and

store the battery current usage value in the generated new location.

18. The mobile device of claim 17, wherein the processor is further configured to replace the previously stored battery current usage value with the battery current usage value if the at least one mode has the previously stored battery current usage value.

19. The mobile device of claim 18, wherein the wherein the processor is further configured to filter the battery current usage value prior to replacing the previously stored battery current usage value to limit an amount of change in the battery current usage value.

20. The mobile device of claim 13, wherein battery current usage values are preloaded into the table prior to first uses of the plurality of modes.

21. The mobile device of claim 13, wherein the mobile device comprises a mobile terminal.

22. The mobile device of claim 13, wherein the processor is further configured to display a plurality of modes for the mobile device in a menu and receive a selection of the at least one mode of the plurality of modes from the menu.
