Most of the time, your phone is in idle mode, gently sipping from your battery's reserve, waiting for incoming calls and routinely connecting to data to update yourGMail and Facebook. Devices in this power-saving mode spend 60 to 80 percent of their time listening, while expending roughly the same amount of power as they do when they're fully awake.
Now researchers at the Universitfy of Michigan have discovered a way to increase battery efficiency when your phone is in battery-draining idle mode.
Called E-Mili, or Energy-Minimizing Idle Listening, the new technological process scales back the wireless card's clock to just 1/16th of its normal operating speeds, and only kicks back into full gear when it senses incoming data. Dubbed "subconscious mode" by Engadget, the new process is said to reduce consumption by around 54-percent for most mobile devices in real-world wireless networks.
