To say I’ve been less than impressed by the iPhone 3GS’s battery life is an understatement. But I won’t give in and slap on one of those giant battery backup slip cases because I think they wreck the phone’s form factor. This however, I do like. It’s a replacement iPhone/iPod Touch USB sync cable that features an inline rechargeable battery. The size difference is negligible, and according to their site the battery is capable of providing an additional talk time 4.5 hours on the iPhone 3G and 9 hours on the 2G, and boost your standby time up to 270 hours. Not bad for about $30 if it works as well as they claim.
