Is my iPhone charger / Lightning cable covered under warranty / AppleCare?
A new iPhone purchase is covered under a one-year AppleCare warranty. You might be wondering if the accessories that come with the iPhone, such as the USB charger and USB to Lighting connector cable are also covered under warranty.
The answer is yes. Getting a replacement USB charger or Lightning cable might require that the Genius Bar see your iPhone to verify purchase date, however in many cases the Apple store or third-party wireless stores have been known to replace malfunctioning iPhone chargers purchased within the last year without any hassle.
