iOS 7 blocks unofficial Lightning cables
Third-party peripherals given the heave-ho.
According to 9 to 5 Mac, iOS 7 blocks third-party cables from charging iKits that use the newish dock standard. That's the iPhone 5, iPhone 5s and iPhone 5c. Official Apple cables pack a chip as a means of authentication.
It’s not clear if all non-certified cables are affected all the time. However, an unreliable charger isn’t much use, given how rubs smartphone batteries are in the first place.
That’s especially the case in light of the fact that some iPhone 5 users are apparently experiencing longevity problems since downloading iOS 7.
The good news is that a workaround exists. Here it is, as determined by the site:
1) Turn on USB power
2) Plug in lightning cable to iPhone
3) Dismiss any warnings
4) Unlock your iPhone
5) Dismiss any remaining warnings
6) Now with the screen turned on.
7) Unplug the knock off lightning cable
8) Plug it back in
9) Dismiss warning again
10) It should now charge.
If that doesn’t work, you might just have to bite the bullet and buy an Apple sanctioned cable.
