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.
