Yes, processors, RAM, screens, and other factors are important in deciding a smartphone, but battery life is increasingly becoming the defining factor. With devices getting thinner and packed with top of the line specs the drain on batteries has increased over the years. Oddly though, very little progress has been made in improving battery life, certainly not like the leaps we have seen in other areas.
MIT startup SolidEnergy says it has made that leap though, with the company claiming that it has created a juicer that has double the life of current standards. SoliEnergy has created a lithium-ion juicer that is says doubles the amount of energy density compared to current packs. The battery features an ultra-thin metal anode, "a thin piece of lithium on copper, that's less than a fifth the size of a graphite anode".
"Think of the largest phone makers out there," SolidEnergy founder and CEO Qichao Hu. "They approached us."
