Apparently, a manufacturing issue has come to the point that Apple is proactively replacing certain iPhone 5S models.
The issue causes the battery to drain and not recharge fast enough. Although Apple is not saying the actual problem, they assure it’s not a battery issue. It’s a good summation this issue could cause the phone to burn out or even become a fire hazzard.
“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,” Apple spokesperson Teresa Brewer told the New York Times. “We are reaching out to customers with affected phones and will provide them with a replacement phone.”
Apple will be contacting those with iPhones that meet the qualification – (i.e. serial number range). This is expected to be a few thousand units. Since Apple has sold over 9 million handsets, this could be (at worst) 1 in 100 handset issue. In the meantime, if you are seeing battery charging issues with your new iPhone, contact Apple support to report the problem so Apple doesn’t overlook your device.
