A new breakthrough technology could help double the lifespan of smartphone batteries.
An MIT spinoff company, ETA Devices, is said to doing this by working on improving power amplifier chips, which transform electricity into radio signals.
Base station and smartphone amplifier chips currently use a significant amount of power, but ETA Devices says it has “cracked the efficiency problem with a new amplifier design” by creating an “electronic gearbox”, which can control different voltages and prioritise to save power.
The technology, called asymmetric multi-level outphasing, does this up to 20 million times per second.
The technology is still in development stages, but could find its way into cell towers in 2013.
