Abstract

An electronic device, method, and computer program product enable limiting electromagnetic emissions from current between batteries. A first battery is positioned proximal to an earpiece speaker within the electronic device. At least one second battery is positioned at a different location within the electronic device that is not proximal to the earpiece speaker. A switch is coupled to a first battery proximal to the earpiece speaker among the plurality of batteries. The switch is selectively toggled to limit current drawn from the first battery while the earpiece speaker is operating, in order to reduce baseband electromagnetic emissions emanating from the first battery.
