Abstract
In embodiments, a mobile device includes a primary battery as a power source to power components of the mobile device, and includes a secondary battery as an additional power source to power the components of the mobile device. A sensor is implemented to detect a free-fall of the device that indicates an impending secondary battery disconnect event due to the mobile device being dropped. A battery controller is implemented to receive a sensor input of the detected free-fall from the sensor. The battery controller can then switch from the secondary battery to the primary battery as the power source based on the detected free-fall of the mobile device. The battery controller can switch back from the primary battery to the secondary battery as the power source based on a lack of acceleration of the mobile device.
