Abstract

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing a user with feedback regarding power consumption in a battery-operated electronic device. In one aspect, a method is performed by one or more data processing apparatus. The method includes receiving, at the data processing apparatus, historical records of power consumption by a collection of battery-operated electronic devices that are operated by different users, aggregating and analyzing, by the data processing apparatus, the historical records to generate representative characterizations of the power consumption on different classes of the battery-operated electronic devices, and outputting, from the data processing apparatus, the representative characterizations of the power consumption by different applications that have executed on the different classes. Each of the battery-operated electronic devices belongs to a class.

Claims

1. A power-management system for electronic devices, the system comprising:

a collection of battery-operated electronic devices each programmed to generate a record of power consumption, each device comprising

a battery,

a data processing unit programmed to execute a plurality of different applications, and

a communication interface for outputting the record of power consumption; and

a server system comprising

a communication interface programmed to receive the records of power consumption output from the battery-operated electronic devices, and

one or more data processing devices programmed to analyze the power consumption recorded in the records to generate a composite value that provides a representative characterization of the power consumption by a first application executed on a proper subset of the battery-operated electronic devices in the collection.

2. The system of claim 1, wherein the server system further comprises a power consumption database storing at least some of the content of the records of power consumption.

3. The system of claim 2, further comprising an anonymizer programmed to anonymize the records of power consumption so that identities of the battery-operated electronic devices or users associated with the battery-operated electronic devices are not discernable from the content stored in the power consumption database.

4. The system of claim 1, wherein the server system is further programmed to analyze the power consumption recorded in the records to identify outliers in the power consumption of a first application.

5. The system of claim 4, wherein:

the server system comprises a database that stores information that identifies characteristics of the battery-operated electronic devices in the collection; and

the server system is further programmed to identify a correlation between the power consumption outliers and a characteristic of the battery-operated electronic devices.

6. The system of claim 5, wherein:

the database stores information that identifies applications installed on the battery-operated electronic devices in the collection; and

the characteristic of the battery-operated electronic devices comprises a second application that is installed on the battery-operated electronic devices in which the power consumption outlier occurred.

7. A method performed by one or more data processing apparatus, the method comprising:

receiving, at the data processing apparatus, historical records of power consumption by a collection of battery-operated electronic devices that are operated by different users, each of the battery-operated electronic devices belonging to a class;

aggregating and analyzing, by the data processing apparatus, the historical records to generate representative characterizations of the power consumption on different classes of the battery-operated electronic devices; and

outputting, from the data processing apparatus, the representative characterizations of the power consumption by different applications that have executed on the different classes.

8. The method of claim 7, wherein outputting the characterizations of the power consumption comprises outputting, to a first battery-operated electronic device that belongs to a first class, instructions for displaying a presentation that includes power rating indicia that indicate an efficiency of power consumed by applications on other battery-operated electronic devices belonging to the first class.

9. The method of claim 7, wherein analyzing the historical records comprises identifying outliers in the power consumption of a first application executing on multiple devices.

10. The method of claim 9, wherein analyzing the historical records further comprises identifying correlations between the outliers in the power consumption and execution of a second application on the multiple devices.

11. The method of claim 9, wherein analyzing the historical records further comprises identifying correlations between the outliers in the power consumption and a presence of a hardware component at the multiple devices.

12. The method of claim 7, wherein:

receiving the historical records of power consumption comprises receiving records of power consumption that is unattributed to particular applications on the battery-operated electronic devices; and

the method further comprises attributing, by the data processing apparatus, the unattributed power consumption to particular applications that are active on the battery-operated electronic devices.

13. The method of claim 12, wherein attributing the unattributed power consumption comprises identifying the active applications from a record of applications installed on the battery-operated electronic devices.

14. The method of claim 7, wherein the representative characterizations comprise:

a characterization of an average power consumption per unit time by a first application that has executed on a first class of battery-operated electronic device;

a characterization of an average power consumption per unit time by a second application that has executed on the first class of battery-operated electronic device;

a characterization of an average power consumption per unit time by the first application that has executed on a second class of battery-operated electronic device; and

a characterization of an average power consumption per unit time by the second application that has executed on the second class of battery-operated electronic device.

15. A computer storage medium encoded with a computer program, the program comprising instructions that when executed by data processing apparatus cause the data processing apparatus to perform operations, the operations comprising:

receiving historical records of power consumption by a collection of battery-operated electronic devices operated by different users;

attributing the power consumption to different applications executing on the battery-operated electronic devices;

generating a collection of composite values that each characterize representative power consumption by one of the applications executing on the battery-operated electronic devices; and

reporting the composite values.

16. The computer storage medium of claim 15, wherein the composite values each characterize representative power consumption per unit time by execution of one of the applications on a different class of battery-operated electronic devices.

17. The computer storage medium of claim 15, wherein the historical records are received during check-ins of individual ones of the battery-operated electronic devices.

18. The computer storage medium of claim 15, wherein the historical records comprise a discharge rate of a battery of the battery-operated electronic devices.

19. The computer storage medium of claim 15, wherein the operations further comprise receiving usage information characterizing usage of applications installed on the battery-operated electronic devices.

20. The computer storage medium of claim 15, wherein the usage information characterizes duration of periods during which applications are used at the same time on the battery-operated electronic devices.
