Every battery has a voltage, called "open circuit voltage". As the battery is used, the open circuit voltage drops. When it reaches a certain value, it is considered dead. The graph of voltage versus time at a given load is published by the manufacturer. Your cell phone uses a lithium ion battery which requires a lot of control circuitry in the charger, and one output from that circuitry is an indication of the open circuit voltage, expressed in percent of life.
