Abstract: Systems of the present disclosure include an electronic device that manages operations in low temperature environments for improved battery performance. Such management can be based on a temperature and/or a charge level of a battery of the electronic device. When the temperature of the battery is below a threshold, the components of the electronic device can be operated to generate heat until the temperature of the battery is at or above the threshold temperature. The operations can be selected and performed based on available charge in the battery, the minimum temperature change that would raise the temperature of the battery to a temperature threshold, the available temperature change that would be induced by performing one or more operations, user inputs, and the like. Such heat generation can allow the electronic device to remain on and maintain its operations despite exposure to an external environment that presents low temperatures.
