IvySkin have released their new SmartCase for the iPhone featuring a battery as part of the packaging for the iPhone and makes the claim to offer double the amount of battery life that the regular battery currently offers.

For anyone who has been out on a long night or that has used their iPhone a bit more than expected during the day, this is something that will surely create interest. Running the different applications, browsing the web and answering a lot of emails takes its toll on the battery life and it is not hard to be down to nothing at 6pm. Having a battery in the case that offers extended life is almost too good to be true.

Of course, this convenience does not come without a hefty price tag. The combination case battery will be no cheaper than buying a backup battery and a skin for your iPhone. The price for the IvySkin SmartCase is $79.99. That is about 40% of what the phone costs in most markets and may be a bit much for some people.
