Two of the reasons Apple’s iPhone is yet to adopt LTE connectivity is that existing LTE chips are just too large for the iPhone’s slender form factor, and they eat up so much power your new iPhone 4S wouldn’t even last the six hours that you currently get if it was hooked up to an LTE network.
However, a new Apple patent application reveals that the Cupertino company has already set about revolutionizing its batteries to make them thinner and more efficient — possibly making way for LTE connectivity in the iPhone 5.
