Abstract
A system with an integrated internal battery, a removable battery, and a power management integrated circuit. The power management integrated circuit is configured to provide power to the image capture device from the removable battery; provide power to the image capture device from the integrated internal battery when the removable battery is disconnected from the image capture device or the removable battery does not have a sufficient charge to drive the image capture device; and recharge the integrated internal battery before the removable battery until the integrated internal battery has a sufficient charge to power the image capture device. The power is continuously supplied to the image capture device from the integrated internal battery while the removable battery is disconnected from the image capture device or does not have sufficient power to drive the image capture device.
