Abstract
Methods and systems are provided for indicating battery information to cellular telephone users when a cellular telephone is near an associated battery charger. When a cellular telephone is within a predetermined range of the battery charger, the charger and telephone form a communication link. The link allows the charger (or telephone) to analyze the status of the telephone's battery, generate alert commands and/or generate sensory alerts as needed in order to warn a user to charge the battery. The charger can also be adapted to establish a communication link with a personal computer (“PC”) and to transmit similar commands to the personal computer via the link to allow the PC to generate sensory alerts.
