None of the above. I am using an iPhone6 purchased from Apple, original cable and charger. Overtime I connected wit the cable to my iMac, the iPhone shows the message but it works with iTunes, it syncs but not charges the iPhone 6. This type of problems never happens with my Samsung Note 4 or Samsung 5.
