Abstract: Aspects of the technology described herein relate to prolonging battery life in an electronic device, such as ultrasound devices. A system may include an ultrasound device and a package. The ultrasound device may include magnetic sensing circuitry. The package may include a lid, and the lid may include a magnet. The magnetic sensing circuitry may control power received by communication circuitry in the ultrasound device based on detecting a magnet that is external to the ultrasound device. For example, the magnetic sensing circuitry may disable power rails in the power circuitry that provide power to communication circuitry when the magnetic sensing circuitry detects the magnet. When the magnetic sensing circuitry cannot detect the magnet, the power circuitry may enter a default state in which power rails provide power to the communication circuitry. The ultrasound device may include an indicator that enters a turn-on sequence when the lid is removed from the package.
