I always liked the OtterBox protection for the iPhone. It’s a bit bulky for me personally but I know plenty of people who use it because their job puts them in a position of damaging their iPhone while at work, so for them the Otter Box is considered the best. Now they have a new version out and this one can charge your battery when it gets low. It monitors both the iPhone battery and the case battery so you can get the most from your battery life. They promise double the battery life.

It is only available for the iPhone 4 and 4S although they have commented that they are considering other devices including the S3.

Here is the official blurb:

The first intelligent iPhone 4/4S battery case power solution for mobile technology, the Defender Series with iON Intelligence unites rugged protection and two times the battery capacity with a power management app for the ultimate experience in empowered protection. This battery case for iPhone 4/4S combines industry-leading and patented three-layer protection of the Defender Series with smart and seamless power.


The iON Intelligence software is an app that estimates battery power and predicts battery time remaining by monitoring your device-usage habits. This app allows you to eliminate guesswork by clearly displaying the power status for both the case and your device and intelligently predicts when your phone battery will run out. The iON Intelligence app monitors and incorporates many different factors to create the most accurate, personalized power profile possible.

This new case, like all OtterBoxes, does not come cheap at $129.95.

It's always nice if you can see it in action:
