Apple may launch three new smartphones on September 12

The report also said that iPhone 9 will be the most-affordable smartphone by Apple in 2018.

Apple is reportedly planning to launch three new smartphones -- iPhone 9, iPhone 11 and iPhone 11 Plus -- on September 12.

"If the rumors are legit, the iPhone 9 will be Apple's 'entry-level' offering and will pack an iPhone X like 6.1-inch LCD screen with room up top for Face ID," the Inquirer reported on Tuesday.

"The iPhone 11 and 11 Plus -- also referred to as the iPhone X2 and iPhone X Plus -- will sport 5.8-inch and 6.5-inch OLED displays, respectively, with rumors also pointing to souped-up camera setups, an upgraded 7nm A11 CPU, and a brand new USB-C charger, the report added.

The report also said that iPhone 9 will be the most-affordable smartphone by Apple in 2018.

According to market research firm TrendForce, Apple's 2018 iPhones will offer Apple Pencil support and up to 512GB built-in storage, the report said.

It's unclear whether these features, similar to those found on Samsung's newly-launched Galaxy Note 9, will be available on all three incoming iPhones or reserved for Apple's higher-end OLED models.

These OLED models will be more expensive than the "budget" 6.1-inch LCD iPhone 9, which Trendforce expects to have a starting price of around USD 699 to USD 749.

The iPhone X (2018) and iPhone X Plus will have starting prices of USD 899 to USD 949 and USD 999, respectively, according to the research firm.

The report confirms that the two OLED models are already assembled, while assembly of the budget LCD model will begin in mid-September, in line with the smartphones' rumored September and October release dates, respectively.

Last year's iPhones were unveiled on September 15 and went on sale in the following week on September 22.
