Battery life for the iPhone, especially for those who use Wi-Fi a lot and 3G, could - to say the least - be better. Thankfully, there's some more help to keep your Apple smartphone up and running longer, the iV from FastMac. While the iV isn't pretty, and it won’t do anything to enhance the inherent of the iPhone, it sure is practical.

The $79.50 external battery charging unit promises to deliver iPhone users with up to 24 hours of talk, 72 hours of audio, 21 hours of video and 750 hours of standby time on a single charge. It can even double as a flash Light and includes a separate USB connector for charging another device, such as a Bluetooth headset. See here to learn more about the iV.
