The iPhone 5S is supposed to have significantly longer battery life than its predecessors. But for a small number of the new models, a manufacturing defect has caused the battery to drain quickly, according to the company.
“We recently discovered a manufacturing issue affecting a very limited number of iPhone 5S devices that could cause the battery to take longer to charge or result in reduced battery life,” said Teresa Brewer, an Apple spokeswoman. “We are reaching out to customers with affected phones and will provide them with a replacement phone.”
Apple did not say how many iPhones were defective, but its statement implied that it was a few thousand phones. In September, Apple said it had sold nine million new iPhones in the first weekend they went on sale.
