The question was; Can the use of an external battery case, harm the life of the internal battery in the iPhone 4? (ie. Mophie Juice Pack Air)
im wondering the same thing
Absolutely not, but if looking for a protective case i would not recommend the mophie but if just using your phone for commercial use, then yes definitely use, it's helpful when you need a cordless charger
