Abstract
Power management notifications are provided to a user of a portable electronic device by monitoring a current power level of a power supply in a portable electronic device. A determination is made, with the portable electronic device, whether the current power level is one of less than and equal to a given threshold. One or more wireless detection operations are performed to determine whether a power supply charging device is in proximity to the portable electronic device. The power supply charging device is unattached to the portable electronic device. A notification is presented at the portable electronic device, in response to both the current power level is determined to be one of less than and equal to the given threshold, and the power supply charging device being wirelessly detected in proximity to the portable electronic device.
