One of the classic bugbears with smartphones is battery life, and most manufacturers - disappointingly - seem more concerned with making things thin and light. Give us more juice!
However, there’s been a bit of a breakthrough that could hypothetically see smartphone battery life as much as double within a few years. Hurray!
The good news is reported over on Technology Review, and we have a Cambridge, Massachusetts-based “MIT spinout company” to thank.
Eta Devices was cofounded by MIT electrical engineering professors Joel Dawson and David Perreault, and they’re reportedly onto something potentially huge by way of a new amplifier design. Eta calls the technology “asymmetric multilevel outphasing”.
The technology is expected to reach commercialisation next year, and will make its debut in power-hungry LTE base stations.
If it proves successful, a smaller scale version of the technology could make its way to smartphones, and threatens to double battery life. Oh baby.
“There really has been no significant advance in this area for years,” says Vanu boss Vanu Bose (you heard me). “If you get 30 to 35 percent efficiency with today’s amplifiers, you are doing really well. But they can more than double that.”
Charging just once every couple of days? That sounds like the kind of future I want to be a part of.
