Abstract
The disclosed embodiments provide a system that monitors a battery in a portable electronic device. During operation, the system monitors a state of charge of the battery while the battery is powering the portable electronic device. Next, when the state of charge of the battery reaches a predetermined reserve capacity, the system monitors a voltage of the battery. Then, when the monitored voltage of the battery reaches a predetermined termination voltage, the system puts the portable electronic device into a low power usage state.
