Abstract

A plurality of client devices may each run on battery power and each experience respective battery usage while in a respective operational state. A server may receive, from the plurality of client devices, a plurality of reports correlating the client devices'"'"' respective operational states with the client devices'"'"' respective battery usage. Based on the reports, the server may identify at least two client devices in the plurality that reported a common operational state. The server may further determine a representative battery usage for the common operational state, and use this representative battery usage to predict battery usage for a particular client device that is in the common operational state. Then, the server may instruct the particular client device to take an action based upon the predicted battery usage.

2. The method of claim 1, wherein instructing the particular client device to take the action based upon the predicted battery usage over time comprises:

predicting a remaining battery duration of the particular client device based on at least the predicted battery usage over time of the particular client device and a current battery level of the particular client device; and

instructing the particular client device to take the action based on the predicted remaining battery duration.

3. The method of claim 2, wherein predicting the remaining battery duration of the particular client device based on at least the predicted battery usage over time of the particular client device and the current battery level of the particular client device comprises:

predicting the remaining battery duration of the given device based on at least (i) the predicted battery usage over time of the particular client device, (ii) the current battery level of the particular client device, and (iii) an idle-state battery usage over time of the particular client device.

4. The method of claim 1, wherein instructing the particular client device to take the action based upon the predicted battery usage over time comprises instructing the particular client device to display the indication of the at least one application operating on the particular client device, and wherein the at least one application is associated with a disproportionate battery usage over time.

5. The method of claim 1, wherein each respective application operating on the particular client device is associated with a respective priority, wherein instructing the particular client device to take the action based upon the predicted battery usage over time comprises instructing the particular client device to display the indication of the at least one application operating on the particular client device, and wherein the at least one application is associated with a priority that is below a given priority threshold.

6. The method of claim 1, wherein instructing the particular client device to take the action based upon the predicted battery usage over time comprises instructing the particular client device to terminate operation of the at least one application operating on the particular client device, and wherein the at least one application is associated with a disproportionate battery usage over time.

7. The method of claim 1, wherein each respective application operating on the particular client device is associated with a respective priority, wherein instructing the particular client device to take the action based upon the predicted battery usage over time comprises instructing the particular client device to terminate operation of the at least one application operating on the particular client device, and wherein the at least one application is associated with a priority that is below a given priority threshold.

8. The method of claim 1, further comprising instructing the particular client device to change at least one setting of the particular client device, wherein the at least one setting is associated with a disproportionate battery usage over time.

9. A server device comprising:

a processor;

data storage; and

program instructions, stored in the data storage, that, upon execution by the processor, cause the server device to (i) receive, from the plurality of client devices, a plurality of reports correlating the client devices'"'"' respective operational states with the client devices'"'"' respective battery usage over time, wherein the respective operational states comprise respective sets of a plurality of applications operating on the respective client devices, (ii) based on the received reports, identify at least two client devices in the plurality that reported a common operational state, (iii) statistically determine a representative battery usage over time for the common operational state based on the reported battery usage over time for the common operational state of the at least two client devices, (iv) use the representative battery usage over time for the common operational state as a basis to predict a battery usage over time for a particular client device that is in the common operational state, and (v) instruct the particular client device to take an action against at least one application operating on the particular client device based upon the predicted battery usage over time, wherein the action comprises one of displaying an indication of the at least one application operating on the particular client device or terminating operating of the at least one application operation on the particular client device.

10. The server device of claim 9, wherein instructing the particular client device to take the action based upon the predicted battery usage over time comprises (i) predicting a remaining battery duration of the particular client device based on at least the predicted battery usage over time of the particular client device and a current battery level of the particular client device, and (ii) instructing the particular client device to take the action based on the predicted remaining battery duration.

11. The server device of claim 10, wherein predicting the remaining battery duration of the particular client device based on at least the predicted battery usage over time of the particular client device and the current battery level of the particular client device comprises predicting the remaining battery duration of the given device based on at least (i) the predicted battery usage over time of the particular client device, (ii) the current battery level of the particular client device, and (iii) an idle-state battery usage over time of the particular client device.
