Yesterday, Apple acknowledged that a manufacturing issue is affecting some iPhone 5s units that causes shortened battery life and longer charging times. The company said that it will be reaching out to customers with these defective units and issuing replacements.
Today we have some more details on this replacement program, by way of the folks at 9to5Mac:
Apple will personally contact customers who own iPhone 5s units with affected serial numbers via a phone call. If a customer feels that their phone is affected, but is yet to receive a call, they may feel inclined to call AppleCare. If they do, the AppleCare representative can program their serial number into the system and check if their phone is eligible for a replacement. If the phone does not deemed to be in the group of units with the manufacturing issue, AppleCare is instructed to troubleshoot the phone with normal guidelines.
If the device is found to be defective, customers can get it replaced by setting up a Genius Bar appointment at their local Apple Store, or heading to their nearest authorised Apple reseller, or asking Apple to ship a replacement device to their house (the old phone will still have to be shipped back to Apple).
It is not clear how many iPhones were affected, but statement suggests that a small percentage of the iPhones may be affected.
