ABSTRACT:
A mobile terminal having a plurality of communication operation modes is operated by determining a current communication operation mode of the plurality of communication operation modes of the mobile terminal, determining a current voltage of a battery that powers the mobile terminal, comparing the current voltage of the battery with a battery voltage threshold associated with the current communication operation mode, and changing the current communication operation mode to another one of the plurality of communication operation modes based on the comparison of the current voltage of the battery with the battery voltage threshold associated with the current communication operation mode.
