I have an iPhone 3gs and my battery life is acceptable with normal use patterns. However, if I’m on the road and use my browser or check my email more often than normal, it is not uncommon for me to see less than half of my battery life left with more than half a day to go. One solution is the Mophie Juice Pack. Essentially, it’s a case for the iPhone that protects it minimally and also ads a reserve battery that effectively doubles the life of your battery.

Seems pretty smart on paper, but has anyone ever tested it out? What were the results? If no comes forward, I’ll see if I can’t get my hands on one and report back.
