Apple is ramping up work on the latest iPhone rumors for a 20th anniversary model it plans to launch next year, and the device is expected to come in two sizes. That would put buyers on a path toward a 6.3-inch version and a 6.9-inch version, both aimed at a more borderless design.
The larger shift is not just the screen shape. Apple also plans to launch a second-generation foldable iPhone in the same window, and all three devices are going to adopt a 2-nanometer A21 chip.
Apple's 6.3-inch and 6.9-inch split
The anniversary pair is expected to track the size of the iPhone 18 Pro and iPhone 18 Pro Max, which means Apple is treating the 20th anniversary lineup like a premium branch rather than a one-off special edition. For readers deciding whether to wait, that points to a clear choice between two large-format models instead of a single flagship shape.
The rumored edge-to-edge display with curved glass at all sides would leave less border around the image area, which is the kind of change you notice every time the screen lights up. Apple has not published the final design, so the only hard detail here is the planned move to two anniversary sizes.
A21, A20 Pro, and A20
Apple's chip plan is more revealing than the design chatter. The iPhone 18 Pro and iPhone 18 Pro Max coming this year are expected to use an A20 Pro processor built on Apple's 2-nanometer process, while the A20 will mark the first node upgrade in several years for Apple's flagship iPhones after a run of 3-nanometer chips.
That means the top end of the lineup gets the newest process first, and the standard iPhone 18 waits for spring 2027 with a less powerful A20 chip on the same 2nm process. The naming suggests Apple is separating performance tiers inside the same manufacturing jump, rather than giving every model the same silicon on day one.
iPhone 18 waits for spring 2027
The complication for buyers is simple. The standard iPhone 18 is not coming this fall, even though the iPhone 18 Pro and iPhone 18 Pro Max are coming this year. Apple instead plans to debut the standard model in spring 2027, which leaves the anniversary phones and the foldable as the next major hardware step for people who want the newest iPhone before then.
The one thing Apple has not settled in public is what will separate the two 20th anniversary sizes beyond display size and the shared A21 chip. Until that becomes clear, the practical choice for buyers is whether to wait for the anniversary pair, move to the Pro and Pro Max this year, or hold off for the spring 2027 standard iPhone 18.
