Apple is gearing up to host an event in September in which it will announce a boatload of upgrades for its existing product lineup. We are expecting the company to announce the iPad mini 6, Apple Watch Series 7, AirPods 3, and most of all the iPhone 13 series. While the flagship smartphones were considered an 'S' upgrade, it seems the company will simply go ahead with the simplistic "iPhone 13" name.

A purported image posted on Weibo confims that Apple will be using the "iPhone 13" name for its upcoming smartphones. The image appears to show sticker tabs which are used to seal boxes of Apple products. The photo was highlighted by DuanRui on Twitter, linking to the source of the image.
