Apple’s September 2026 event: Everything we know about the iPhone 18 Pro and the foldable iPhone Duo

If you’re eyeing an iPhone upgrade this September, the equation is a bit more complicated than usual. Apple is reportedly splitting its big September reveal into two relatively smaller but equally important product drops: iPhone 18 Pro and iPhone Duo (the rumored foldable) this fall, and the regular iPhone 18, iPhone Air 2, and the iPhone 18e in spring 2027. 

That means anyone who wants a new iPhone in September most likely has three options, all at the premium end of Apple’s lineup, including a foldable that could cost as much as a laptop. As mentioned earlier in this roundup, the company sent out invitations for its September event on August 26, 2026, confirming the iPhone 18 Pro launch event. But what about the phones? Plenty of rumors from reputable sources paint a picture of what to expect from Apple’s 2026 September event. 

When is Apple’s September event happening?

This year, the Apple September event will take place on September 9, 2026, from 10 AM PT. You can watch the livestream via the company’s official YouTube channel, while Apple will also drop releases once everything is announced.

Pre-orders for the announced iPhones could begin on September 11 or 12, likely the latter, as Apple might want to sidestep the 25th anniversary of 9/11 on September 11, with retail availability expected from September 18. That is everything we know about Apple’s launch timeline for the upcoming iPhones. Below are details on the three expected iPhones.

iPhone 18 Pro: Silicon refresh with minor upgrades across the board

The iPhone 18 Pro could be a classic example of Apple’s tried-and-tested playbook of making the biggest leap under the hood while keeping everything else relatively familiar. To begin with the expected changes, we could see a slightly smaller Dynamic Island. Some reports point to under-display Face ID components, though I don’t think it will happen this year. 

The 6.3-inch display size is expected to carry over unchanged from the iPhone 17 Pro. Under its shiny aluminum and glass exterior, the iPhone 18 Pro could sport the new A20 Pro chip, which could be Apple’s first chip to embrace the highly efficient 2nm fabrication technology (after Samsung). 

Rumors also mention a new Wafer-Level Multi-Chip Module (WMCM) packaging, which places the CPU, GPU, Neural Engine, and memory closer together for better performance and AI efficiency. A new in-house C2 modem is also expected to debut on the flagship, potentially running alongside Qualcomm hardware depending on region, likely with expanded satellite connectivity that unlocks 5G via satellite.

Like every year, the new iPhones will ship with stable iOS 27 builds and deeper Apple Intelligence integration, including the new Siri AI experience, new editing features in Photos, and a couple of other new features. On the optics front, the most repeated rumor is new variable-aperture hardware paired with the primary sensor, giving photographers more control over depth and low-light performance. 

A 24MP selfie camera is also expected (up from 18MP), likely with the square-shaped camera sensor that enables the Center Stage camera experience on the iPhone 17. Battery capacity estimates vary across sources, but I expect them to be similar to the iPhone 17 Pro: around 4,288 mAh for the eSIM-only model and 4,065 mAh for the ones with a physical SIM. 

Initially, the price was expected to rise by $200 to $300 over the iPhone 17 Pro’s $1,099 starting price. However, according to Mark Gurman’s latest newsletter, both the iPhone 18 Pro and the iPhone 18 Pro Max could cost only $100 more than their current equivalents. That puts the prices at $1,199 and $1,299, respectively.

iPhone 18 Pro Max could pack similar internals in a bigger chassis

The iPhone 18 Pro Max should carry the same core upgrades as its smaller sibling, scaled up to fit the larger 6.9-inch form factor. Expect the same shrunken Dynamic Island, the same A20 Pro chip on TSMC’s 2nm node running iOS 27, and the same C2 modem with expanded satellite internet as the iPhone 18 Pro. 

When it comes to optics, a recent rumor claims the variable-aperture primary camera could be exclusive to the Pro Max variant. However, that would leave buyers with one less compelling reason to consider the iPhone 18 Pro, especially if they’re coming from the iPhone 17 Pro. It could also further narrow the gap between the iPhone 18 Pro and the regular iPhone 18.

The Pro Max could really pull ahead in battery capacity. The numbers differ across sources, so I won’t confuse you with them. However, we could be looking at a ~10% bigger battery on the upcoming handset compared to the iPhone 17 Pro Max’s eSIM-only (5,088 mAh) and physical SIM (4,823 mAh) batteries. 

If that happens, the iPhone 18 Pro Max could offer a few more hours of use between charges, making it the longest-lasting iPhone Apple has ever shipped. However, pricing is where the handset starts looking less impressive.

That’s a meaningful jump for buyers already stretched by rising memory costs across the entire smartphone industry this year. Apple may or may not offset that increase by bumping the base model storage from 256GB to 512GB, but the price hike seems inevitable. A recent rumor also suggests the iPhone 18 Pro models could be in short supply at launch, possibly extending delivery times.  

Apple’s first foldable might be available in limited quantity at launch

Apple’s first foldable iPhone, widely expected to carry the “Ultra” moniker, could be called the iPhone Duo, according to Mark Gurman’s latest report. It could be the company’s most important launch in a few years, especially after the last big design breakthrough with the iPhone X in 2017.

Renders point to a short, wide, “passport-style” book-fold with a 5.5-inch cover display and a 7.8-inch inner display at roughly a 4:3 ratio, closer to an iPad mini or the recently launched Galaxy Z Fold 8. Thickness estimates land around 4.5 mm unfolded and 9-9.5 mm folded. Contrary to initial rumors, the device could come in dark blue and white.

A couple of days ago, Gurman mentioned how the iPhone Duo might not support an Apple Pencil, at least not the model that goes on sale this year. However, in his latest newsletter, Gurman says the foldable will include Apple Pencil support after all. Apple might have tweaked the Pencil’s design a bit. I am most excited to see how the company sorts the storage and charging situation.

While it might not be the thinnest foldable available at launch, Apple is reportedly working on the handset’s hinge and crease, using liquid metal and ultra-thin glass to strengthen them, respectively. For the chassis, the company might go with a mix of titanium and aluminum. The foldable could also feature a Touch ID biometric authentication system to make up for the lack of Face ID. 

Under the hood, the iPhone Duo will most likely run on the A20 Pro (2nm) chip with Apple’s C2 modem. Like the Pro models, the foldable could pair the silicon with 12GB of RAM, with 256GB of storage on the base variant. While the rest of the lineup will share Siri AI and the iOS 27 experience, the foldable iPhone could get a multi-app split-screen layout to leverage the extra screen real estate. 

The handset could feature a dual-camera setup similar to the iPhone 17: a primary and ultrawide sensor with 48MP resolution. However, contrary to earlier rumors of 18MP sensors, the latest leaks point to a single 12-megapixel front camera. It’s still unclear whether the front-facing camera will feature Center Stage.

For those wondering about the battery, Apple could go with a dual-cell design with a combined capacity of around 5,000 mAh or more. Some rumors also suggest the iPhone Duo could have the biggest battery Apple has ever shipped. However, that could seem less impressive once you see the rumored price and release date.

The baseline iPhone Duo with 256GB will start at $2,000, while fully loaded 2TB configurations will reach up to $3,000. Also, the foldable will not be available for purchase alongside the rest of the iPhone 18 Pro models. It might not go on sale until at least October.

Should you buy now or wait?

If you’re using an older iPhone, like an iPhone 12 or iPhone 13, and you’ve been waiting for the iPhone 18 series to upgrade, keep two things in mind before you decide. First, there might not be a baseline iPhone 18 at the September launch event. Second, the new iPhone 18 Pro models could command a $100 premium over the iPhone 17 Pro. 

If you ask me, the iPhone 17 or iPhone 17 Pro is still an excellent upgrade for anyone using an iPhone 14 or older. Practically speaking, you can buy it right now instead of waiting for the September event. However, if budget isn’t a constraint for you and you’re comfortable paying a higher asking price, you could wait and see what Apple has in store.

Beyond the hardware, this keynote marks a historic shift in Apple’s leadership. Following a planned transition on September 1, former hardware chief John Ternus has officially taken over as CEO. Tim Cook has transitioned to Executive Chairman of the Board, making this fall showcase the first hosted under Ternus’s leadership.
