    I picked up a Mophie Juice Pack Reserve to be able to recharge my iPhone 4 when on the go. Nowhere in the documentation does it talk about charging the iPhone itself. Say I let it get down to 0%, would it charge 50%? Less? More? It's rated at 1000 mAh, whatever that translates to. Thanks!

    according to iFixIt the battery in the iPhone4 is a "3.7V 1420 mAh Li-Polymer battery" .. so you should get about 70% charge from 0.

    Thanks. I did manage to perform a mini-test, my battery was down to 66%, I loaded the Mophie fully juiced and it fully charged my iPhone in about 35-40 minutes and had one dot left on the meter. Cool little charger.
