Aspects of the disclosure provide an electronic device and methods for determining energy efficiency of the electronic device that receives wireless communication service from a network. The electronic device includes processing circuitry. The processing circuitry is configured to determine an amount of data transmitted between the electronic device and the network over a duration. The processing circuitry is configured to determine energy consumption of the electronic device over the duration based on a power consumption model. Further, the processing circuitry is configured to calculate an energy efficiency indicator based on the amount of data transmitted and the energy consumption. In an example, the processing circuitry is configured to report the energy efficiency indicator to the network.
