Abstract: An electronic device having a housing, a battery, a charging circuit, a plurality of temperature sensors in the housing, a processor operatively connected with the battery, the charging circuit, and the plurality of temperature sensors, and a memory. The memory storing instructions configured to, when executed, enable the electronic device to measure temperature values using one or more of the plurality of temperature sensors, in response to a temperature value associated with the battery being within a threshold value, calculate a predicted surface temperature based on at least one of the measured temperature values and a position of each temperature sensor, identify a control step among a plurality of control steps based on an operational state of at least one device associated with the electronic device and the predicted surface temperature, and adjust charging power for the battery through the charging circuit in response to the identified control step.
