    Abstract: The subject matter of the disclosure relates to low temperature power throttling at a mobile device to reduce the likelihood of an unexpected power down event in cold weather environments. A mobile device employing a power management solution may be configured to determine that a monitored temperature at the mobile device (at the battery of the mobile device) is below a first threshold level, and whether a hardware component (such as a camera) is active or inactive. Then, based on these determinations, the mobile device can select a throttle setting from a first set of throttle settings when the hardware component is active, and a second set of throttle settings when the hardware component is inactive. Subsequently the mobile device can throttle power consumption for one or more components of the mobile device according to the selected throttle setting.

    Abstract: Systems and methods are disclosed for allocating and distributing power management budgets for subsystems (e.g., power usage clients) of a computer system. A power budget allocation subsystem may include a plurality of feedback branches having different associated time constants. Power usage clients with slower power response times may be provided power budgets based on a feedback branch having an associated longer time constant, while power usage clients with faster power response times may be provided with power budgets based on a feedback branch having an associated shorter time constant. The power budgets may be determined in the feedback branches based on power budgeting policies weighting the power budget of each subsystem relative to total power mitigation.

    Abstract: An electronic device may have electrical components that produce heat during operation. An electronic device may also be heated by sunlight incident on the device. A thermal management model may take into account device structures such as housing materials in modeling the thermal behavior of the device. Temperature sensors in the device may be used to measure internal temperatures. The model may use temperature measurements and other data such as environmental data measured with sensors in predicting temperatures for one or more regions in a device. In response to prediction of a temperature greater than a predetermined threshold, the device may take remedial action to avoid overheating. Remedial action may include adjusting electrical components so that they produce less heat, activating a heat blocking component such as an electronic shutter, and reducing communications activity levels and other software activity levels.
