We will have Silicon Carbon battery that has 2x energy density of normal lithium battery shipping on Smartphone later this year. Apple is very slow in new battery technology adoption, but one could imagine in a few years time this iPhone Air will have double the battery life.

I've had this in my Oppo Find N5 for the last half year already. Bigger battery than any iPhone on the market including the upcoming ones.
And that certainly wasn't the first on the market silicon carbon phone
