Power management of a wireless communication device

A nontransitory computer readable medium, having thereon a computer program comprising program instructions, the computer program being loadable into a data-processing unit and adapted to cause execution of a power management method of a wireless communication device when the computer program is run by the data-processing unit, wherein the wireless communication device comprises a modem for wireless communication and a battery for supplying power to the modem, wherein the method comprises:

• obtaining information regarding a power consumption of the modem as a function of time, the information being provided by the modem during wireless communication;
• forming power consumption statistics from the obtained information, wherein the power consumption statistics comprise an average power consumption during wireless communication as a function of one or more time parameters;
• and
• controlling use of the modem by one or more applications of the wireless communication device based on the power consumption statistics,
• wherein controlling use of the modem comprises:
• causing communication of the one or more applications to take place at a first time when the average power consumption during wireless communication is less than a threshold value;
• and
• presenting, via a user interface of the wireless communication device, information regarding a second time when starting of an application is suitable based on the power consumption statistics.

A power management arrangement of a wireless communication device, wherein the wireless communication device comprises a modem for wireless communication and a battery for supplying power to the modem, the arrangement comprising:

• an information obtainer adapted to obtain information regarding a power consumption of the modem as a function of time, the information being provided by the modem during wireless communication;
