For example, the change in temperature at which the electronic device stops charging the battery is a change in temperature that exceeds the change in temperature 435 during the time interval 405 (eg, the change in temperature 445 corresponding to the graph 440). As described above, after the start of charging the battery based on the signal received wirelessly, in response to identifying a change in temperature that increases relatively rapidly for a specified period of time, the electronic device transmits the signal.
