The Nexus 5 is the second phone we’ve seen that incorporates envelope tracking technology, which has nothing to do with mail delivery. The technology greatly reduces the power needed to transmit an LTE signal.
Quantance has gone back to its investors for a $12 million Series D, which it plans to use to bring its envelope tracking chip to market. The technology promises significant gains in LTE device battery life.
VoIP may be the future on mobile communications, but new findings from testing outfit Spirent show the technology needs to improve its power efficiency if it’s to become viable. Its tests found that a VoLTE call consumes twice as much battery life as a 2G call.
Nujira has developed technology that eliminates the enormous energy waste of LTE radios. By utilizing a technique called envelope tracking it matches the power fed into the handset with the power it transmits, which could cut down smartphone battery drain by a quarter.
