<p>A mobile electronic device can operate in multiple modes, each at a respective current load. Monitoring a battery in such a mobile device includes acquiring a sensed battery voltage (46) during a particular operating mode (48) and converting the sensed battery voltage to a scaled voltage (50) for a known battery discharged curve having a well defined turn-off voltage. The known battery discharged curve is preferably one for a full current load. The scaled voltage is then compared with the well defined turn-off voltage (52) to determine the amount of energy remaining in the battery. Operating times for other operating modes can also be calculated and displayed for the user's information.</p> |
