Apple Increases iPhone 5C and 5S Battery Sizes relative to iPhone 5
 

While poking through the FCC documents and piecing together a story on the network band situation for the iPhone 5S and 5C, I remembered that part of a normal disclosure is in fact battery size. Apple noted the battery on the iPhone 5C increased, and I've been curious about the 5S battery size as well given the different PCB photos with slightly changed aspect ratio that floated around as potential candidates for the 5S. Apple also doesn't disclose the battery size in Whr or mAh on their tech spec pages, making this the only real place to find out outside of opening them up and looking once they're available.
