During the time that I owned my iPhone 4 and 4S, those phones spent most of their lives in a Mophie Juice Pack Air. That battery pack got me through some of those scary situations where I had spent a couple of hours geocaching, making calls and sending texts, only to find that I was down to 5 percent of charge capacity and was nowhere near a power outlet. So when the iPhone 5 came out last fall, my first thought for a case was a Mophie product. It took a few months, but now the Mophie Juice Pack Helium (US$79.95) is available to protect and power the iPhone 5.
