A New Chip Makes Voice Control More Efficient, Less Creepy

Maximizing battery life remains the great challenge of every smartphone manufacturer. People use their phones for everything these days, and of course they want a battery that lasts forever, and charges in minutes. Engineers have a few ways of tackling this problem beyond packing a bigger, and potentially more dangerous, lithium-ion battery inside. The most effective trick is making the chips, drivers, and other components as energy efficient as possible. The obvious targets include big screens, 4G modems, and Bluetooth.
