Device serial numbers reveal inaccurate warranty period.
A consumer rights activist has a filed a lawsuit against Apple at a Chinese court accusing the firm of selling refurbished iPhones, according to Shanghai Daily.
He claims the company is trying to pass them off as new at a Beijing store.
The report says Wang Hai is representing two consumers who bought iPhones complete with a one-year warranty in July but upon examination of the serial numbers, the warranties were revealed to expire within six months time.
Hai and his clients claim this is evidence that the phones are second-hand as it's doubtful they were festering in a warehouse.
Hai, said: "It is a very serious discrimination to Chinese consumers, because refurbished phones are being sold at cheaper prices abroad, but the same as new ones in China."
The lawsuit has been accepted by the court and a hearing date is due to be arranged shortly.
