Batteries showing reduced performance is a normal occurrence, but that usually happens after a device has been used for more than a year or so. Thanks to the removable back plate, users can easily exchange the faulty battery for a new one, but they shouldn't need to be doing this just six months after buying a brand new phone. The issue seems to be limited to only one country for now, so it's possibly a case of poor quality assurance on a particular batch of batteries, but it's something Samsung nonetheless needs to look into.
Any of you having the same issues with the battery on the Galaxy S4?
