Good news for everyone: battery life for both the iPhone 5s and iPhone 5c will be better than the iPhone 5, if new FCC filings are anything to go by.
Anandtech has gotten its hands on the FCC documents for the iPhone 5s and iPhone 5c:
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.
At the end of the day, it actually turns out that both the iPhone 5s and iPhone 5c are getting small-to-sizable battery life increases. On the iPhone 5c, you can expect a modest 5% bump in battery life over the iPhone 5, but it’s the iPhone 5s that really gets the boost: it boasts a 1507mAh battery compared to the 1440mAh battery in the iPhone 5. That’s a battery life boost of over 10%!
