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 controller is electrically connected to a switch that is electrically connected in-line with the first battery. The controller selectively toggles the switch between first and second switches state. The controller initiates activation of a first software mode of the electronic device corresponding to operation of the earpiece speaker. In response to detecting the activation, the controller toggles the switch to the first switch state in which the switch limits current drawn from the first battery while the electronic device is in the first software mode, thus reducing baseband electromagnetic emissions emanating from the first battery.
