<p>A few days ago I updated my iPhone 5 to IOS 7 and now, when I plug it in to charge, it tells me that the lead is not Apple approved and may not work properly. If I don't press 'Dismiss this Message' the phone won't charge. I am using the lead and plug that came with the phone. My wife's iPhone 4 charges normally. Any ideas?</p><p>Michael Ulliott, by email</p><p>This new feature in iOS 7 is supposed to prevent the use of unlicensed and potentially dangerous accessories that use the Lightning Connector, which explains why your wife's iPhone 4 is unaffected as this uses the old style 30-pin Dock connector.</p><p>Unfortunately it seems that the new software is a touch too enthusiastic as there are quite a few reports of it rejecting Apple supplied cables, as well as cables and chargers that worked perfectly well under iOS 6.</p><p><a href="http://www.telegraph.co.uk/technology/advice/10483769/My-iPhone-wont-charge-now-I-have-updated-to-iOS-7.-Help.html">Keep reading...</a></p>
