In some embodiments, an electronic device displays one or more representations of power usage of the electronic device, including across various periods of time and subperiods of time within those periods. In some embodiments, the displayed information reflects power usage both for periods of the display being on and periods of the display being off. In some embodiments, the displayed information includes power usage attributed to various mobile applications running on the electronic device. In some embodiments, the electronic device displays recommendations to reduce the usage of power by the electronic device, which a user has the option of applying. In some embodiments, the electronic device displays prose insight into power usage, indicating causes of the power usage.

User interfaces for indicating battery information on an electronic device

An electronic device having a user interface for displaying battery usage of the device over a given time period. Suggestions to improve device battery life are displayed along with usage when battery savings suggestions criteria are met.

Battery usage tracking user interface

Techniques are disclosed performing a power logging in a computer system at a sub-process level. An exemplary method includes an operating system of the computer system determining process information indicative of which sub-portions of one or more processes are running on the computer system at different points in time, as well as may determining power information for the computer system at different points in time. The operating system may the create, from the process information and the power information, a power log indicative of power usage of sub-portions of processes at a plurality of points in time. The power logging may extend to both core and non-core resources of the system. For non-core resources, the power usage may be estimated in some cases based on the type of non-core resource being called as well as parameters passed to the non-core resource.

Microprocessor power logging at a sub-process level

Circuits, methods, and apparatus that may estimate the power being consumed by an OLED display screen of an electronic device, may provide further information about that power usage, may modify or change functions performed by the electronic device based on that power usage, and may inform an application's developer about the amount of power being used by the electronic device while the electronic device is running the application. One example may estimate the power being used by an OLED display screen of an electronic device by determining the content of images being displayed during a duration. The estimated power may then be presented to a user. The estimated power may be used in decisions to modify or change parameters of the screen or other device components.

Graphically providing OLED display power modeling

Some embodiments of the invention provide a novel architecture for debugging devices. This architecture includes numerous devices that without user intervention automatically detect and report bug events to a set of servers that aggregate and process the bug events. When a device detects a potential bug event, the device in some embodiments generates a description of the potential bug event, and sends the generated description to the server set through a network. In addition to generating such a description, the device in some embodiments directs one or more of its modules to gather and store a collection of one or more data sets that are relevant to the potential bug event, in case the event has to be further analyzed by the server set. In the discussion below, the generated bug-event description is referred to as the event signature, while the gathered collection of data sets for an event is referred to as the event's data archive. The server set aggregates and processes the bug-event signatures that it receives from the various devices. For only a subset of the reported bug-event signatures, the server set then directs the devices that sent these signatures to also send the data archives that these devices have gathered and stored for the events associated with these signatures. These data archives can be further analyzed to identify the root causes of the bug events.

Auto bug capture

OLED display power modeling

A portable electronic device having a user interface for displaying battery usage of the device over a given time period, with the battery usage from various subsystems. The various subsystems including at least one hardware subsystem and the battery usage attributed to a plurality of software applications based on activity of the plurality of software applications, while battery usage of the various subsystems was monitored.

Systems and methods are disclosed for determining hours of utility of an application per amount of energy consumed by the application for a wide variety of device types. For each subsystem of a client device, a model of the subsystem is used to estimate a portion of the total energy consumed by the subsystem during a predetermined period of time. Energy consumed by a subsystem is apportioned to one or more applications or daemons that utilize the subsystem. Energy usage by a daemon is apportioned to one or more applications that the daemon performs work on behalf of. A large sample of application energy consumption information is gathered by an energy server and provided to an application information server that is accessible by developers. Thus, a developer can view energy consumption vs. application utility, by client device type and by subsystem for the client device type.

Application power usage

In some implementations, a system can intelligently restore data to a user's computing device. For example, the system can prioritize data to be restored to a user device based on the data that the user is most likely to use. The system can restore high priority data items first while delaying restoration of low priority data items. The system can control when data restoration is performed based on device conditions. For example, the device conditions can include how much of an energy budget and/or data budget remains for downloading data to the user device. The device conditions can include the thermal condition (e.g., how hot) of the user device. If device conditions do not allow for downloading data at a particular time, then the device can delay downloading data until the device conditions allow for downloading and/or restoring the data.

Intelligent restoration of a computing device

In order to reduce latency associated with an application executed by an electronic device, when the application transitions from a runnable mode to a suspended state, the electronic device may receive a request from the application to maintain a connection, which is used by the application to communicate with another electronic device, while the application is in the suspended state. Then, the electronic device may provide an instruction to an interface circuit in the electronic device to maintain the connection for a time interval while the application is in the suspended state. This time interval may exceed a predefined timeout for the connection and/or a task extension time for the application. Moreover, prior to providing the instruction, the electronic device may confirm one or more system safeguards to prevent abuse and to ensure system performance and battery life is not adversely affected by maintaining the connection.

Maintaining network connections for background applications

A method and apparatus of a device for performance management by terminating application programs that consume an excessive amount of system resources is described. The device receives a resource consumption threshold and a detection period. The device further monitors a resource usage of an application program. The device determines whether the resource usage of the application program exceeds the resource consumption threshold for the detection period. The device further terminates the application program when the resource usage exceeds the resource consumption threshold for the detection period.

Performance management based on resource consumption

Systems and methods are described for communicating between VoIP applications installed on a mobile computing device and their corresponding servers using a cloud-based notification infrastructure. In one aspect, a method is performed by a notification handler executing on a mobile computing device and includes the actions of maintaining a persistent network connection between the notification handler and a notification server associated with the notification handler; receiving, over the persistent network connection, an incoming call notification for a VoIP application installed on the mobile computing device, the received incoming call notification being relayed by the notification server from a VoIP server to which the VoIP application is associated; determining, in response to the receiving of the incoming call notification, that the VoIP application is in an inactive state; and activating the VoIP application on the mobile computing device to provide information relating to the received incoming call notification.
