Submission + - 'Subconscious mode' could boost phone battery life (

cylonlover writes: University of Michigan researchers have proposed a new power management system for smartphones that could dramatically improve battery life. The system, known as E-MiLi, or Energy-Minimizing Idle Listening, addresses the energy waste that occurs when "sleeping" phones are looking for incoming messages and clear communication channels. E-MiLi slows down the clock of a phone's WiFi card by up to 1/16 its normal frequency in order to save power, but then kicks it back up to full speed when information is coming in. The phone uses the header of the incoming message to wake itself up from its "subconscious mode," so the clock is at full speed to receive the main message. For users on the busiest networks, it could extend battery life by up to 54 percent.
