Abstract
Approaches provide for managing a multiple battery system in an electronic device. In particular, various examples enable a component, or combination or components, such as an electronic switching component to detect a state of a power source to manage switching between at least two power sources. For example, battery protection circuitry can be configured to detect that a voltage of a rechargeable battery has dropped to a threshold voltage, and upon such determination, activate a battery protection state which can result in a non-linear drop off in voltage coming from the rechargeable battery. An electronic switch can detect the non-linear drop off in voltage and can disconnect the rechargeable battery from at least one device component and connect a non-rechargeable battery to the at least one device component to provide backup power to at one component.
