No, but the majority of the iPhone 6Ses that are shutting down are in China due to Apple stocking up the US with phones made prior to the September/October 2015 window, while the Chinese iPhones were made during that period. However, there are some that are in the rest of the world and the battery exchange for the batteries assembled in September and October 2015 applies everywhere if your serial number shows your iPhone was made during that period.
I have one. Nice to see a free battery replacement in my near future. Timely!
