Smartphones are one of hottest trends in consumer electronics. According to the Federal Communications Commission, their use has increased 700 percent over the past four years. And it’s no surprise why. Combining the functions of a personal computer (PC), mobile phone, personal media player and recorder in a single device, consumers are using them to organize data, manage e-mail, access the Internet, listen to music, play games, take and view still photos and videos, handle voice calls, and even navigate their way around.

All of this is placing greater demands on the smartphone hardware, which is being asked to deliver ever increasing performance while at the same time keeping power consumption to a minimum, even as consumers expect longer battery life from their devices. These demands will only increase as the industry moves from current 3G to 4G networks.

With faster data rates, and with mobile data projected to increase at a rate of 130 percent annually, consumers will migrate to using their smartphones for more media-rich applications. As consumers spend more time using their devices as multimedia platforms, they will expect higher-quality audio and video performance as well as a battery life that accommodates these longer use times.
