Battery disconnect safeguard
First Claim
1. A system, comprising:
- a primary battery configured as a power source to power components of a mobile device;
a secondary battery configured as an additional power source to power the components of the mobile device; and
a battery controller configured to switch from the secondary battery to the primary battery as the power source based on detected acceleration of the mobile device and no detected touch contact with the mobile device, wherein the detected acceleration indicates an impending secondary battery disconnect event due to the mobile device falling.

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.
