Just another idea to help extend your iPhone battery, which I’ve read doesn’t last very long, a Solar Charging case from MobileFun. MobileFun claims it will provide your iPhone with one full charge, and I assume if the case is fully charged. According to Ecogeek.org it can take up to 10 hours to fully charge the case (if I’m reading this correctly). It seems like a good idea if, at the end of the day, your iPhone is petering out and you need it to last just a bit longer. These are due out in Mid-August for approximately $54.80 USD or £27.95 pounds.
