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 an acceleration of the device that indicates an impending secondary battery disconnect event due to the mobile device falling. A battery controller is implemented to receive a sensor input of the detected acceleration 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 acceleration of the mobile device. The battery controller can switch back from the primary battery to the secondary battery as the power source based on the acceleration of the mobile device no longer being detected.
