Received message about "uncertified cable" when plugging phone in to Apple supplied cable

Connected my iPhone 5 to my iMac via Apple supplied cable, connected to my keyboard. Received message stating the cable was "not certified and could damage device if used" or words close to that ...


This is one of the Lightning cables I have purchased from Apple, used with this phone in this configuration with no prior issues.


I noticed this morning that the battery had not charged overnight, was dangerously low. Phone still showed in iTunes, was able to sync.


Charged phone using my iPad wall adapter, phone is accepting charge. Plugged it back into the iMac, no error message.


A bit confused by this.

iPhone 5, iOS 7.1.1

Howdy Bob,


It sounds like there is an intermittent issue with the USB adapter cable or the iPhone. Take a look at the articles linked below, they will provide insight and troubleshooting suggestions that should help resolve the issue.


iPhone and iPod touch: Charging the battery

http://support.apple.com/kb/ht1476

Connect your device to a USB port on your computer (not an external keyboard) using the USB cable that came with the device. Your computer must be on.

Some third-party cables and accessories that aren't Apple certified, or are FireWire equipped, may not charge your device properly. If you see either of the alerts below, the device may not charge. Try another cable or accessory.

  • "This cable or accessory is not certified and may not work reliably with this iPhone."
  • "This accessory is not supported by this device."


If either of these alerts appear and nothing is connected to the dock connector, make sure that the dock connector is free of debris.
