Apple’s upcoming iPhone 11 is expected to be available on September 13 for pre-order and in-store availability is set to start on September 20. Information about the release date for iPhone 11 was obtained from an inside source working at a major carrier, MacRumors revealed on Friday.

The Cupertino-based company has already sent out invitations for its annual iPhone event on September 10. The event will take place at the company’s Apple Park headquarters in Cupertino, California.

The iPhone-maker would launch three iPhone 11 models this year — The D43 (internal name) would replace the iPhone XS Max, the D42 (internal name) would replace the iPhone XS and the N104 (internal name) would replace the iPhone XR.

The new iPhone 11 models replacing the iPhone XS series would have a triple rear camera setup at the back and all three sensors will be placed at the back. Known Apple analyst Ming-Chi Kuo had also earlier suggested that the upcoming iPhone models would be equipped with reverse wireless charging.

The iPhone maker is also anticipated to introduce bundled larger batteries along with their upcoming iPhone products for 2019. This year, it is expected that Apple’s iPhone XR will display a 3,110mAh battery that is larger than the 2,942mAh battery the firm introduced to iPhone XR introduced in 2018.
