You know what we always say: never enough battery life. Energizer's new AP1201 case for the iPhone 4 should come as a welcome addition to your Apple gadget family. As a slim, protective case of silicone rubber it's not completely offensive looking (if fact, it's pretty attractive), and it charges your phone while it's wearing it. It's got two charging options -- a high speed charging mode which charges the phone first, then the case, while the other option provides simultaneous pass-through charging. The case promises to about double the life of your iPhone, and it's available now for $69.99.
