The [iPhone 5s](https://www.apple.com/iphone-5s/specs/) has a storage temperature requirement of -20C to 45C.

Mind you, storing a li-ion battery in extreme temperatures is never a good idea. You are going to shorten the useful lifetime of the battery. I don't think it it will break or anything, though.
