A common problem with smartphones is that users always need to approach the power supply because of limited battery life. But now a new chip can greatly extend the battery life of smartphones and even save energy for mobile phones. The new chip from the MIT spin-off called ETA equipment aims to expand the battery life of smart phones, and even double the battery life. According to the Massachusetts Institute of Technology, it has been determined that the culprit in smartphone battery power consumption is an inefficient power amplifier.
The power amplifier pushes the wireless signal from the antenna assembly of the smartphone. The technology of ETA equipment was disclosed for the first time in November 2012. After the test, the laboratory results showed a 50% reduction in power consumption. But now MIT has fully developed it into a smart phone chip. This new technology is based on research conducted by MIT in the last decade. When smart phones send data, power amplifiers tend to stay at maximum voltage and consume power at an alarming rate. ETA chip is a special "switching device" to adjust the power supply voltage of the power amplifier to reduce energy consumption.
