Abstract
An electronic system may include an electronic device and a power maintenance device. The electronic device may include a battery and a memory. The memory may include a test function block configured to monitor a level of the battery to generate a control signal for maintaining the level of the battery within a range of a set low level. The power maintenance device may control an electrical connection between an external power source and the battery based on the control signal.
