Abstract
A portable multi-band communication device has a power amplifier, a battery for supplying power to the power amplifier, and a controller, which controls an output power level of the communication device by generating a digital control signal for the power amplifier. The controller monitors the digital control signal and in response determines a consumption of electric energy from the battery.

9. A method of determining a charge consumption for a portable battery-powered communication device including a radio transmitter, a power amplifier operatively connected to the radio transmitter, and a controller operatively connected to the power amplifier, wherein an output power level of the radio transmitter is controlled by the power amplifier through a digital control signal from the controller, and wherein the radio transmitter is furthermore responsive to a control signal strobe, the method comprising:
-
storing a set of predetermined consumption values providing an association between different amounts of electric charge consumption and respective values of the digital control signal, detecting the control signal strobe, determining a value of the digital control signal, selecting, from said set of predetermined consumption values, a value which corresponds to the determined value of the digital control signal, and updating an accumulated charge consumption value to reflect the selected value. - View Dependent Claims (10)
