1. An electronic device comprising:
a transceiver configured to receive WI-FI traffic for an application in a target wake time (TWT) operation; and
a processor operably coupled to the transceiver and configured to:
identify whether a state of the electronic device is idle or active based on at least one of a traffic statistic related to the WI-FI traffic or an application identifier of the application; and
adjust a TWT interval of the TWT operation based on the state,
wherein the processor is configured to:
determine, after identification that the state is idle, that the state has changed to active based on a most recent traffic statistic that is observed in a most recent window of previous TWT service periods (SPs) being larger than previous traffic statistics observed in previous windows, or based on the most recent traffic statistic exceeding a threshold; or
determine, after identification that the state is idle, that the state has changed to active upon determination, based on the application identifier, that the application does generate WI-FI traffic.
