Abstract: The disclosed technology relates to a portable electronic device. The portable electronic device may comprise a battery, a battery controller, and a system controller. The battery controller may be configured to determine real time battery state information associated with the battery, the real time battery state information including a system load current draw, a battery age indicator, and a battery temperature. The system controller may be configured to determine a user initiated current low voltage mode state of the portable electronic device of a plurality of low voltage mode states, receive current battery state information from the battery controller, and adaptively generate a real time shutoff voltage threshold based on the current determined low voltage mode state and the current battery state information.
