Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
