According to the report, Samsung has some 2.5 million Galaxy Note 7s left over after using 20,000 or so up in testing to determine the cause of the problem. The refurbished devices will have new cases, and batteries with a capacity between 3,000 and 3,200mAh (the phones initially contained a 3,500mAh battery). Reuters reported last month that the sale of refurbs is a possibility, and ZDNet Korea says it will also help the company avoid trouble with the government over junking all of the unused and returned phones.
