Wireless communication system with enhanced power management

摘要

A method is provided for a wireless communication device containing at least a main processor for data processing, and a transmitter and a receiver for wireless communication. The method includes providing power to the main processor using a power source via a power switch, performing device initialization of the wireless communication device, and determining whether the wireless communication device recovers from a power-down standby mode, where the power source is disconnected to the main processor such that the main processor does not consume power from the power source. Further, the method includes recovering device states based on information stored on a non-volatile storage when it is determined that the wireless communication device recovers from a power-down standby mode. The method also includes reporting device status including at least battery level of the wireless communication device to an external server based on configuration information on the wireless communication device.
