Apple has released a new message Fix a fix that prevents turning on some iPhone 6S and 6S Plus phones.
"Apple has determined that certain iPhone 6s and iPhone 6s Plus devices can not be powered on because of a potentially faulty component." The page for the program is "iPhone 6s and iPhone 6s Plus Powerless Device Service Program."
This does not apply to all iPhone 6S and 6S Plus devices. Rather, this applies to phones in a particular range of serial numbers that corresponds to some handsets sold between October 201
The Apple service page prompts users to enter their serial numbers to verify that their devices are affected. The company also notes, "If your iPhone has damage that interferes with the repair, such as a broken screen, this issue must be resolved prior to servicing, which in some cases may incur costs for additional repair."  If the user's serial number matches the bill, Apple will service the affected devices through an Apple Store, a mail-in service, or an Apple Authorized Service Provider. The company also states that users who have already paid out of pocket to resolve the problem can apply for refunds. However, all of these offers only apply to phones purchased within two years of contacting Apple.
Apple has offered similar repair programs for its products in the past; B. Mac laptops with broken butterfly keyboards. The iPhone 6S and 6S Plus are currently the oldest iPhones supported by Apple's latest iOS 13 software release. With iOS 12 last year, Apple has been trying to improve the performance of these phones with newer software, in some cases extending its life.
