If you have ever dropped an iPhone, or been lost for battery power at a critical time, you’ll know “that” feeling. The iPhone isn’t cheap, and without protection it can easily break if dropped, so a reliable case can become a very important consideration.

In this review we’ll be taking a look at the Otterbox Defender Series with iON Intelligence case for iPhone 4/4S current available for around £74.49 ($129.95 in the US).

The first thing about the Otterbox that catches the attention, other than the interesting name, is the word “iON”.

According to the dictionary an “ion” is one or more electrically charged atoms so if you think this case has something extra to offer you would be right.

The Defender Series with iON Intelligence is a protective iPhone battery case that adds an app which integrates with the iPhone. Otterbox sum up this case with the phrase “protection, power, and prediction.”
