Potentially really exciting stuff but... Please, someone in Apple, this time stand up to Jony Ive (or whoever is really responsible for Apple's thinness obsession) and use any space savings inside the case to increase battery size rather than let the physical designers grab all the benefits from these sorts of technical innovations and use them to make the device even thinner. I think we must be at at least a 10 to one ratio now between people saying "I want longer battery life" vs people saying "I'd like the next iPhone to be even thinner". I'm still waiting for the iPhone when Apple decides to throw everything at battery life. Big efficiency improvements in components together with actually using extra space in the case gained from higher levels of integration to increase battery size really might at some point let Apple bump battery life 30-40% and maybe more between iPhone models without needing to roll out some new exotic battery chemistry (although if they could do that as well then even better).
