I have had a battery case for my iphone 5 about 3 months after the phone come out . Never had a problem with the battery case . But then I did the update to ios 7 . Now it will not let me use . Why why why are you doing this Apple ???????

Are you kidding me? What are you, 5 years old?

Updating the iOS has no effect on an external battery source. I have a Mophie and it's working just fine. You probably have lint or some other debris in the docking port of the iPhone.

Let's not be too judgemental gdgmackguy, reports of this all over the place. A reset may fix it, but I think it may be deeper than that.

Time will tell.

Contacting the manufacturer of the accessories would be a good call too. They may have some insight.

I have a PowerGen 8400mAh External Battery Pack that my family and I have used on many occasions to charge the 3 iPhones we have. (2 iPhone 5 and a 4s). I discovered this past weekend after going on a 40 mile bike ride that my trusted battery will no longer work after I updated to iOS 7. I use an Apple lightning cable to connect the battery but get "This accessory may not be supported" message after plugging it in. Why is Apple making many once supported accessories obsolete? This external battery has been a life saver on many occasions. It may be time to make the switch to another smart phone if Apple keeps this up.

Theresava, I would check with PowerGen and see if they have a solution.

Not really trying to side with Apple but I would assume some of this stems from The 2 Chinese women that got electricuted with Non-Apple certified chargers.
