The iPhone 6S and iPhone 6S Plus (stylized as iPhone 6s and iPhone 6s Plus) are smartphones designed, developed and marketed by Apple Inc. The devices were announced on September 9, 2015, at the Bill Graham Civic Auditorium in San Francisco by Apple Inc. CEO Tim Cook, and went on sale on September 25, 2015.

The iPhone 6S has a similar design to the 6 but updated hardware, including a strengthened chassis and upgraded system-on-chip, a 12-megapixel camera, improved fingerprint recognition sensor, and LTE Advanced support.
