On stage at the company's live event at its Apple Park campus in California, a fourth generation Apple Watch was also announced by the firm. But if you are going to buy one of the older phones, especially the iPhone 6 and iPhone 6s, make sure you verify the health of their batteries and replace them before Apple's deal expires.
The iPhone Xs has a 5.8-inch OLED screen, which is the same as last year's iPhone X, but with a more impressive Super Retina display.
The company said the iPhone XS and iPhone XS Max will have dual-SIM and dual standby technology.
In China, the new iPhones will feature two physical SIM cards, while the rest of the world will get a software-based SIM standard using the eSIMs with support from telecom carriers.

Apple iPhone XR models rest on a table during a launch event on September 12, 2018, in Cupertino, California.
Apple bills the iPhone XR as "the iPhone X experience in an LCD display". Instead, it uses haptic feedback like a trackpad when you long-press an icon on the display. The A12 Bionic also has a 50% faster GPU and an improved neural engine.
The XR features numerous same specifications as the XS duo but has only a single rear camera, an LCD screen - unlike the XS' OLED - and starts at £749 when it goes on sale in October. In Kenya the prices are expected to be slightly higher than in the United States.
