The iPhone-maker is also expected to put bigger batteries and some real internal upgrades in the new iPhones.
Aiming to take on Huawei and other Chinese rivals, Apple is also mulling the resurrection of the cheaper iPhone SE for emerging markets, especially India and China, early next year.
The new model would be Apple's first low-cost smartphone since the launch of the iPhone SE in 2016, which started at $399.
Apple is also expected to launch an upgraded Apple Watch in titanium and ceramic variants at the event.
Whether this will be called Apple Watch 5 or a premium upgrade to the current Watch Series 4 is yet to be known.
The new Watch models would come in both the 40mm and 44mm versions.
Apple may also announce pricing plans for Apple TV+ with premium streaming content and Apple Arcade, its gaming service.
