According to an ongoing thread over at Reddit, though some non-certified cables are still working, many do not. Other people have confirmed this as well.
I have a cable which worked perfectly fine on iOS 6.1.4. But now on iOS 7, it will not charge the phone whether using the mains adapter or via USB.One commenter added:
Yes I get the “cable not certified” message everytime, but until recently my cheap cables worked fine. I plugged one in to my work computer to charge and was greeted with a new message, asking if I “trusted this computer.”There seems to be a workaround solution:
So everytime I plugged my phone in I had to dismiss the “certified” message and accept the “trusted” prompt. After a few times, the cable stopped working. Used another cheap cable, same thing happened.
- Turn on USB power
- Plug in lightning cable to iPhone
- Dismiss any warnings
- Unlock your iPhone.
- Dismiss any remaining warnings.
- Now with the screen turned on.
- Unplug the knock off lightning cable.
- Plug it back in.
- Dismiss warning again
- It should now charge
