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.
