An apparatus, system and method notifies a user of a low battery condition when the remaining battery capacity of a portable electronic device, such as a mobile station, pager, portable computer, video camera, or personal digital assistant, falls below a predetermined level and the portable electronic device is proximally located to a corresponding charging unit. The proximity of the portable electronic device to the charging unit may be detected by using geographic positioning, such as the GPS, the GLONASS or the GSM location-determining algorithms, or by monitoring a short range radio interface, such as Bluetooth or Home RF.
