A team of researchers at a startup called Eta Devices have purportedly found a way to reduce smartphone battery consumption by half.
A power amplifier is one of the more wasteful power consumption components of a smartphone's battery. It's a chip that's utilized to convert electricity into radio signals, as well as to maintain a device's connection to a wireless network.
Power amplifiers waste around 65 percent of a handset's battery power and also cause a smartphone to heat up when a user streams a video or uploads large files.
Eta Devices, however, has redesigned the power amplifier by making use of technology dubbed "asymmetric multilevel outphasing". It selects the minimum voltage required to maintain a connection, and updates around 20 million times per second in order to deliver the highest efficiency.
The group behind the firm is currently developing the new power amplifier technology for cellular base stations, which also suffer from similar power consumption issues. The new chips are scheduled to be shipped sometime during 2013.
The startup firm said its plans for creating a single power amplifier chip could lead an energy efficiency revolution on smartphones. The technology behind the new power amplifiers would ensure smartphone batteries would last twice as long as they normally would. The chip would also make it possible to implement the amplifier in CPU and display technologies.
