Abstract

A processing device assigns a wake-up quota to an application, the wake-up quota comprising a time period. The processing device determines whether the application has met or exceeded the wake-up quota in the time period. Responsive to determining that the application has met or exceeded the wake-up quota in the time period, the processing device limits at least one of future alarm wake-ups, future network wake-ups or wake locks for the application.

First claim

What is claimed is:

1. A mobile computing device comprising:
a memory; and
a processing device operatively coupled to the memory, the processing device to:
gather information on device wake-up events, wherein a first device wake-up event is associated with a first application of a plurality of applications and comprises at least one of a network wake-up event that activates the processing device responsive to receipt of a packet over a network, or an alarm wake-up event that activates the mobile computing device at a specified time;
determine statistics about the device wake-up events associated with the plurality of applications based on the information;
identify, based on the statistics, that the first application is responsible for a certain percentage of the device wake-up events; and
apply a wake-up restriction policy for the first application, wherein to apply the wake-up restriction policy the processing device is to:
assign a wake-up quota to the first application, the wake-up quota comprising a time period;
determine whether the first application has met or exceeded the wake-up quota in the time period; and
limit at least one of future alarm wake-up events, future network wake-up events or wake locks for the first application after the first application has met or exceeded the wake-up quota in the time period.

2. The mobile computing device of claim 1 , wherein to limit the future network wake-up events the mobile computing device uses a network wake-up filter, the mobile computing device further comprising:
a network device, coupled to the processing device, to apply the network wake-up filter, wherein to implement the network wake-up filter the network device is to:
determine whether a source of a received network packet is a restricted source that is associated with the first application based on searching the network wake-up filter for an entry that matches the source; and
drop the packet without activating the processing device responsive to a determination that an entry in the network wake-up filter matches the source.

3. The mobile computing device of claim 1 , wherein to limit the future alarm wake-up events the processing device is further to:
identify a future alarm wake-up event that is requested by the first application;
determine whether the future alarm wake-up event is within the time period; and
responsive to a determination that the future alarm wake-up event is within the time period, prevent the future alarm wake-up event from activating the processing device at a specified future time.

4. The mobile computing device of claim 1 , wherein the processing device is further to:
determine power consumption values associated with the plurality of applications based on the statistics about the device wake-up events;
generate rankings of the plurality of applications based on the power consumption values; and
determine separate wake-up restriction policies for the plurality of applications based at least in part on the rankings, wherein the separate wake-up restriction policies have different wake-up quotas.

5. A method comprising:
assigning a wake-up quota to an application, the wake-up quota comprising a time period and an allowable number of wake-up events within the time period;
determining, by a processing device, that the application has met or exceeded the wake-up quota in the time period; and
limiting at least one of future alarm wake-up events, future network wake-up events or wake locks for the application, wherein limiting the future network wake-up events comprises at least one of a) performing a transmission control protocol (TCP) reset to a network connection associated with the application or b) implementing a network wake-up filter that filters out network packets associated with the network connection.

6. The method of claim 5 , wherein limiting the future alarm wake-up events comprises implementing an alarm wake-up restriction policy that causes the future alarm wake-up events of the application to be removed from an alarm wake-up schedule.

7. The method of claim 5 , further comprising:
permitting at least one of the future alarm wake-up events, the future network wake-up events or the wake locks after the time period is reset.

8. The method of claim 5 , further comprising:
gathering information on device wake-up events associated with the application, wherein the device wake-up events comprise at least one of network wake-up events that activate the processing device responsive to receipt of packets over a network or alarm wake-up events that activate the processing device at specified times;
determining statistics about the device wake-up events associated with the application based on the information; and
generating the wake-up quota based on the statistics.

9. The method of claim 5 , wherein the application is one of a plurality of applications, the method further comprising:
determining a first power consumption value and a first importance value associated with the application;
determining a second power consumption value and a second importance value associated with a second application of the plurality of applications;
determining the wake-up quota for the application based on the first consumption value and the first importance value; and
determining a second wake-up quota for the second application based on the second consumption value and the second importance value, wherein the wake-up quota is different than the second wake-up quota.

10. The method of claim 9 , wherein:
determining the wake-up quota comprises categorizing the application into a first category based on the first consumption value and the first importance value, wherein the first category is assigned the wake-up quota; and
determining the second wake-up quota comprises categorizing the second application into a second category based on the second consumption value and the second importance value, wherein the second category is assigned the second wake-up quota.

11. The method of claim 5 , wherein the wake-up quota applies only to alarm wake-up events, the method further comprising:
assigning an additional wake-up quota to the application, wherein the additional wake-up quota applies only to network wake-up events.

12. A method comprising:
assigning a wake-up quota to an application, the wake-up quota comprising a time period and an allowable number of wake-up events within the time period;
determining, by a processing device, that the application has met or exceeded the wake-up quota in the time period;
limiting at least one of future alarm wake-up events, future network wake-up events or wake locks for the application; and
after the time period is reset, permitting at least one of the future alarm wake-up events, the future network wake-up events or the wake locks.

13. The method of claim 12 , wherein limiting the future alarm wake-up events comprises implementing an alarm wake-up restriction policy that causes the future alarm wake-up events of the application to be removed from an alarm wake-up schedule.

14. The method of claim 12 , further comprising:
gathering information on device wake-up events associated with the application, wherein the device wake-up events comprise at least one of network wake-up events that activate the processing device responsive to receipt of packets over a network or alarm wake-up events that activate the processing device at specified times;
determining statistics about the device wake-up events associated with the application based on the information; and
generating the wake-up quota based on the statistics.
