Abstract:
A controller detects the temperature of a portable electronic device as being below a battery charging threshold, and in response signals one or more of the electronic circuit components that make up the device to enter an increased power consumption state so as to generate more heat in the device for warming up the battery. Other embodiments are also described and claimed.
