It has been confirmed that Apple will launch the iPhone 11 smartphone on September 10, both iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max will be released on that day.
The pre-order can be done on September 13, or 3 days after the launch, with Apple doing this almost every year already. Therefore is not uncommon.
And there is a high possibility that the three iPhone models that will actually be on sale will be on September 20, which will be on sale in some countries first. The sale, after a week of pre-order, is a tradition that Apple has followed the launch of the new iPhone models as well.
In 2018, the iPhone XS and XS Max were released at the same time, only the iPhone XR was released in October. In 2017, the company released the iPhone 8 and 8 Plus at this time of the same year, with the iPhone X being released in November. And it is likely that Apple will follow this tradition in subsequent years as well.
