MIT spinoff company, Eta Devices has achieved a breakthrough in the power amplifiers and promises that it would almost double your smartphone battery life. What this means is that your iPhone will actually last longer than 10 hours and your Android will live for more than a day even for the power users. The company says that they'll begin the commercial production in 2013 and will demo it at the Mobile World Congress in Spain. The company wants to aim the developing world first but the technology would definitely be adapted my all the mobile hardware makers.

5 Red Dots Represent Component That Eat 60% Of iPhone 5's Power[/caption]
Eta Devices is founded by MIT electrical engineering professors, Joel Dawson and David Perreault has developed this technology called "asymmetric multilevel outphasing". It improves the life of the battery by using the lowest amount of standby power possible. When the data transmission and reception rate is high, the mobile devices end up using more standby power - which results into the phone getting warmer. The latest advancement allows selection of voltages to the transistors that minimize the power consumption at a very rapid rate - about 20 million times a second.
The company wants to make a power amplifier that will handle all the different transmission / reception modes like CDMA, GSM, 4G LTE etc. iPhone 5, for example, uses 5 different chips to achieve this (see image above). We hope the technology finds its way to the smartphones soon.
