i LOVE the Otterbox brand. I've bought 2 defenders in the past with no problems. However, I was very disappointed that this Otterbox didn't work. I went back and looked at the advertisement and no where could I find that the Otterbox comes with an inner "attachment" that converts the power cord for an iphone 4s to be a micro insert. (I thought the reference to Ion intelligence was just the app that told you about battery status. Because of this converstion attachment, my iphone 4s was drained completely from 100% power within 4 hours without using it and on airplane mode. The Otterbox itself looks great and sturdy but because of the flaw in the charging method of it, I had to return it because the phone could not keep a charge for more than a few hours at a time.
Came quickly, super durable, easy to use, great product! I haven't used it long enough to say for sure, but with the way this wraps around your iPhone, I can't possibly see how your phone could get damaged.
Case won't charge. Read other reviews and saw the same issues. Some seem to work some don't. Only reason not returning is that we leave for vacation tomorrow and need the case for the protection of the phone. Do not purchase this for the feature it offers. Case is a little heavier and bulkier because of the ion battery feature.
