Apple has posted notice of a new repair program to address an issue that prevents some iPhone 6S and 6S Plus phones from turning on.

“Apple has determined that certain iPhone 6s and iPhone 6s Plus devices may not power on due to a component that may fail," the page for the program says. The program is wordily called "iPhone 6s and iPhone 6s Plus Service Program for No Power Issues."
