摘要： An electronic device includes: a location measurement circuitry; a rechargeable battery; a memory configured to store instructions; and at least one processor. The at least one processor may be configured to execute the instructions to: monitor a usage pattern of the battery while the electronic device operates in a first power management state; acquire, based on determining that the usage pattern of the battery is different from a reference pattern derived from a model, information on a location in which the battery is estimated to be charged and information on a time at which the battery is estimated to be charged using the model; and switch, partially based on the information on the location and the information on the time, the first power management state to a second power management state based on a second maximum driving frequency lower than the first maximum driving frequency.
