A portable communication device (1) has a plurality of electronic circuits (212, 214, 216), a battery (270) for supplying power to the circuits, a controller (240) and a memory (244, 310). The controller controls the operation of at least some of the circuits by providing control signals (TX str, RX str, Synth str), for which the circuits are responsive. The memory (310) is provided with a set of predetermined consumption figures (TxCurrent, RxCurrent, SynthCurrent) related to a respective amount of electric energy consumed by the circuits (212, 214, 216) in response to a respective control signal. The device also comprises means (247, 300) for counting the control signals (TX str, RX str, Synth str) and for determining, by using the set of predetermined consumption figures, a value (Total_Current) representing the consumption of electric energy from the battery (270). |
