Abstract: This disclosure provide various techniques for decreasing the amount of energy consumed on an electronic device by one or more background processes. By implementing a fast energy accounting engine that may quickly detect changes in energy usage by the background processes and report the changes to a dynamic activity scheduler, a system may decrease the overall energy consumed by the one or more background processes.

Abstract: A power system uses a power transmitting device to charge batteries in power receiving devices. Wireless power is transmitted using coils in the power transmitting device and coils in the power receiving devices. Usage history information such as power consumption, times and dates of device usage, battery charge state information, device location information, and other information is gathered using portable electronic devices in the system. Control circuitry in the power transmitting device or elsewhere in the system controls power transfer so that battery charging is performed in accordance with appropriate battery charging settings. Battery charging settings such as maximum charge level, charge rate, charging start and stop times, and other settings are adjusted based on usage history information from one or more devices and/or one or more users.

Abstract: A method of controlling charging of an electronic device includes estimating a usage time value that corresponds to an anticipated future occurrence of usage of the electronic device; and estimating a resume time value that corresponds to a time for charging to commence to allow for completion of charging from a first predetermined state of charge value to a second predetermined state of charge value by the usage time value. The method also includes charging a battery of the electronic device using electrical power supplied by a charging device until a current state of charge of the battery reaches the first predetermined state of charge value, entering, by the electronic device, a deactivated mode after the current state of charge reaches the first predetermined state of charge value, and causing the electronic device to return to the activated mode according to the resume time value.

Abstract: An electronic device can include a power system including a battery and a processor programmed to: receive synchronized context data from one or more other devices associated with a user of the device, determine, at least in part based on the synchronized context data, one or more battery charging intervals, and operate the power system to charge the battery from the external power source during the identified one or more battery charging intervals. The processor can be programmed to determine the one or more battery charging intervals using a machine learning model. The synchronized context data can provide indication of the user's location. If the synchronized context data indicates that the user is at a different location than the device, the one or more battery charging intervals determined based at least in part on an expected time for the user to return to the location of the device.

Abstract: An electronic device can include a power system including a battery and one or more processors programmed to: detect that the electronic device has been connected to a power source, predict using prior usage data of the electronic device whether battery usage between an expected time of disconnection from the power source and a next expected time of connection to the power source exceeds a threshold, and if the predicted battery usage between an expected time of disconnection from the power source and a next expected time of connection to the power source does not exceed the threshold, charge the battery to a state of charge less than the full state of charge of the battery.

Abstract: An electronic device may have a power system. The power system may receive power such as wireless power or wired power and may use a portion of the received power to charge a battery. Power consumption by control circuitry in the device can be adjusted by deactivating or activating processor cores in the control circuitry and by selectively starting or stopping software activities. By selectively reducing power consumption by circuitry in the electronic device other than battery charging circuitry in the power system that is charging the battery, additional power may be made available to charge the battery and/or battery capacity can be extended. The electronic device may reduce non-battery-charging activities in the device in response to information gathered with sensors such as motion and temperature information, information from the power system, information on device location, information on software settings, and other information.

Abstract: This application relates to techniques that adjust the sleep states of a computing device based on proximity detection and predicted user activity. Proximity detection procedures can be used to determine a proximity between the computing device and a remote computing device coupled to the user. Based on these proximity detection procedures, the computing device can either correspondingly increase or decrease the amount power supplied to the various components during either a low-power sleep state or a high-power sleep state. Additionally, historical user activity data gathered on the computing device can be used to predict when the user will likely use the computing device. Based on the gathered historical user activity, deep sleep signals and light sleep signals can be issued at a time when the computing device is placed within a sleep state which can cause it to enter either a low-power sleep state or a high-power sleep state.

Abstract: Embodiments described herein provide techniques to encode sequential data in a privacy preserving manner before the data is sent to a sequence learning server. The server can then determine aggregate trends within an overall set of users, without having any specific knowledge about the contributions of individual users. The server can be used to learn new words generated by user client devices in a crowdsourced manner while maintaining local differential privacy of client devices. The server can also learn other sequential data including typed, autocorrected, revised text sequences, sequences of application launches, sequences of purchases on an application store, or other sequences of activities that can be performed on an electronic device.

Abstract: Embodiments described herein provide for a multi-device context store in which context attributes of multiple devices can be synchronized. A first device can transmit a predicate to a second device, where the predicate includes a condition associated with an attribute of a multi-device context store. Upon the occurrence of the condition at the second device, a notification and/or context update can be sent by the second device to the first device. The predicate can also include a code block to be executed upon the occurrence of the condition.
