The iPhone's battery problem is really a long-standing problem. Couldn't you think about charging one day? The Etón brand now offers the mobius solar charging case for the iPhone 4/4S. The 1800mAh battery capacity, along with other cases with back-up batteries, has a common drawback - it's thick. It may be more suitable for fieldwork friends, usually not really interested in such a large shell.
Look at the solar charging efficiency:
Solar charging for one hour:
3G call 25 minutes
3G Internet 20 minutes
Watch the video 35 minutes
Listen to the song 145 minutes
Of course, this case can also use micro-USB charging, black and white, and sells for $80.
