A wireless communication device, a wireless communication system, and a method for optimizing battery power resources are described. The wireless communication device comprises a rechargeable battery, a control module, and a display. The control module is operatively coupled to the rechargeable battery and is configured to determine a first remaining battery time associated with a first operational mode, and a second remaining battery time associated with a second operational mode. The display operatively is coupled to the control module and is adapted to display both remaining battery times. The wireless communication system comprises antennas configured to communicate using both operational modes. The method comprises accessing a network system, estimating battery metrics based on current battery power, querying a table that associates battery power metrics with different radio access technologies, and generating a table output that displays the remaining battery time associated with each of the wireless technologies.
