Abstract: An electronic device can include a processor programmed to detect connection of an external power source to the electronic device, determine an estimated disconnection time at which the external power source is expected to be disconnected from the electronic device, analyze power grid data corresponding to the external power source to identify one or more desired background processing intervals and one or more undesired background processing intervals prior to the estimated disconnection time, and perform background processing during the identified one or more desired battery charging intervals and inhibit background processing during the one or more undesired battery charging intervals. The processor can be programmed to determine an estimated disconnection time using a machine learning model.

Abstract: An electronic device can include a power system including a battery and a processor programmed to detect connection of an external power source to the electronic device, determine an estimated disconnection time at which the external power source is expected to be disconnected from the electronic device, analyze power grid data corresponding to the external power source to identify one or more desired battery charging intervals and one or more undesired battery charging intervals prior to the estimated disconnection time, and operate the power system to charge the battery from the external power source during the identified one or more desired battery charging intervals and inhibit battery charging during the one or more undesired battery charging intervals. The processor can be programmed to inhibit battery charging by reducing the rate at which the battery charges or by preventing battery charging.

Abstract: An electronic device can include circuitry that measures power delivered to the device and one or more processors configured to calculate power or energy drawn from a power grid by the device over a time period based on one or more measurements of power delivered to the device. The one or more processors can include a model of one or more power adapters characterizes load versus efficiency for the adapter. The circuitry that measures power delivered to the device can measure power delivered to the device via a wired and/or a wireless interface. The one or more processors can be further configured to estimate a carbon footprint of the device from the calculated power or energy drawn from the power grid by the device over the time period. The one or more processors can be further configured to communicate the estimated carbon footprint to an external device.
