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.
It turns out that there are in fact some battery size increases for both the 5S and 5C if the FCC disclosure is to be believed. While I'm somewhat skeptical sometimes of the accuracy of battery capacities as reported in FCC disclosures (which I noted about the battery size for the Nexus 5), these numbers seem credible given what I've heard, the statement Apple made during the keynote about the 5C battery size going up, and what I'd expect with some board re-layout for the 5S. The iPhone 5S ends up getting an almost 10 percent increase in size versus the iPhone 5, the iPhone 5C goes up around 5 percent versus the iPhone 5.
فیل شیلر در مراسم اپل اعلام کرد که باتری داخل آیفون 5C از باتری آیفون 5 بزرگتر و پرظرفیت تر است ولی دقیقا اشاره ای نکرد که به چه میزان این ظرفیت افزایش یافته. همچنین درباره ظرفیت باتری آیفون 5S نیز کاملا سکوت کرد.
