Lightening Cable that shipped with iPhone5 now not certified

Since upgrading to iOS7 charging the phone has become problematic.

I now get this warnng saying the cable or accesory is not certified this is the Lightening Cable that shipped with the iPhone so it would have a certified chip.

If I move the cable charger & phone to a different power point this sometimes allows charging.

I have a couple of questions that arrise having read about these glitches.

Is it possible that the certified chip has somehow been burnt out (possible in the iOS 7 upgrade)?

I have read that now the Lightening connector is now handed(as a result of iOS7) so there is now a right way up?

One persons solution is to pull the cable up firmly to the left side front and hold the cable in place with an elastic band whilst charging .

I do not expect to have to jiggle cables and change to different power outlets to enable charging firstly changing wall sockets in a newly rewired house would point more at a poor connection with the Lightening plug & socket.

There has also been suggestions that the socket in the iPhone can become restricted through lint (fluff) it sounds posible but why should this rear its head after the instalation of iOS7?

Were this the case then surley the cable would not be seen at all so there would be no chance of receiving a message informing me that my Apple Lightening cable (as supplied with the phone ) is not autherized ?

So is the autherization chip overly sensative to the effects of a reboot after the iOS7 upgrade and the succesive ones since and has become corrupted?

This Lightening cable issue is most tiresome having to waste time just to charge the phone daily & then I have the prospect of spending up to half a day getting to the Apple Store to see if this can be resoved .

Is this genuine Lightening cable(not been recognised) issue caused by iOS7 or the result of dirt in the socket preventing charging .

Assuming that the issue has been caused by a worthy idea of protecting the user from injury from non Apple accesories with a clever tweek to the iOS an immenant fix lke yesterday would be good .

I am not used to this from Apple products (they simple work) and hope that this is resolved rapidly since I am getting to feel like throwing my iPhone out of a high window or beating it with a large hammer .
