Patent Images
1. A method for managing use of a battery in a portable electronic device, comprising:
- attempting to regulate, from a charging circuit, a voltage on a battery terminal in the portable electronic device to a first voltage level;
upon identifying an inability to regulate the voltage on the battery terminal to the first voltage level during a first detection period, attempting to regulate the voltage on the battery terminal to a second voltage level; and
upon identifying an inability to regulate the voltage on the battery terminal to the second voltage level during a second detection period following the first detection period, detecting the presence of the battery in the portable electronic device.

Abstract
The disclosed embodiments provide a system that manages use of a battery in a portable electronic device. During operation, the system attempts to regulate a voltage on a battery terminal in the portable electronic device to a first voltage level. Upon identifying an inability to regulate the voltage on the battery terminal to the first voltage level during a first detection period, the system detects a presence of the battery in the portable electronic device.
