1. A method, comprising:
- coupling a battery simulator to a mobile station, the battery simulator configured to provide the mobile station with a simulated battery voltage;
measuring, for a predetermined time period, a plurality of current measurement data points of the mobile station in standby mode;
calculating, from the plurality of current measurement data points, an average current consumption associated with the mobile station in the standby mode;
determining an actual battery capacity of a battery for the mobile station; and
determining a standby time of the mobile station based on the average current consumption and the actual battery capacity.

Abstract
A method and system for determining standby time for a mobile station uses a battery simulator, a base station emulator, a computer to control the test equipment and MSUT for testing a mobile station. The computer includes a module for determining a radio off battery voltage, a module for deriving a battery capacity in dependence upon the radio off battery voltage, a module for measuring battery capacity usage in a predetermined time while the mobile station is in standby mode and a module for determining a standby time for the mobile station in dependence upon the battery capacity and the battery capacity usage, where the predetermined time is less than the standby time.
