    Abstract: A method is disclosed. The method can include receiving a command to shut down an electronic device based on a measurement of power delivery to the electronic device. After receiving the command to shut down, the method can determine whether an indication of remaining power capacity at the electronic device exceeds a threshold value. The method can shut down the electronic device and, after shutting down the electronic device, in accordance with a determination that the indication of remaining power capacity exceeds the threshold value, automatically reboot the electronic device. In accordance with a determination that the indication of the remaining power capacity does not exceed the threshold value, automatically rebooting the electronic device can be foregone.

    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: An electronic device that displays a battery status is described. In particular, based on the occurrence or presence of an environmental condition (such as an extrinsic environmental factor and/or a current electronic-device usage factor), the electronic device may determine an inaccessible-charge condition of a battery in the electronic device. For example, the environmental condition may include: a temperature of the battery less than the temperature threshold value; and/or a discharge rate of the battery greater than the discharge threshold value. In response to the inaccessible-charge condition, the electronic device may display indications of two or more battery-charge parameters, including: an accessible battery charge, an inaccessible battery charge that is currently unavailable for use because of the environmental condition, and/or a total battery charge.

    Abstract: An electronic device may have a power system with a battery. The device may include power management circuitry that helps distribute power from the battery to components within the device. To prevent an excessive load from being applied to the battery and the battery from dropping below a cut-off voltage, power management circuitry may control power consumption by components in the device. Power consumption models in the power management circuitry may be used to ensure that maximum allowable power consumption levels are not exceeded. To help accurately and quickly manage power consumption decisions, each component may have characteristic power consumption values that characterize the power consumption profile of the component. These characteristic power consumption values may be provided to the power management circuitry with a request for power consumption and the power management circuitry may determine maximum allowable power consumption for the component based on the characteristic power consumption values.
