Apple just launched the iPhone 17, but the tech world is already buzzing about the next model. Early leaks suggest that the iPhone 18 lineup will mark the most dramatic shift in Apple’s smartphone strategy in years, transforming its design, performance, camera system, and display technology.

From dropping Qualcomm to embedding Face ID under the display and potentially unveiling the first foldable iPhone, 2026 may redefine Apple’s mobile identity.

1. Apple may say goodbye to Qualcomm

According to multiple sources, Apple is currently testing its in-house C2 modem, the successor to the C1 modem integrated into the iPhone 16e. If successful, this 5G chip would mark Apple’s full independence from Qualcomm, its long-time modem supplier.

The C2 modem is said to offer improved mmWave support and smarter multi-network connectivity, boosting download speeds while significantly optimizing power efficiency. This would be a major step in Apple controlling its entire telecom hardware stack.

2. Variable aperture camera for Pro models

One of the most anticipated camera upgrades is the inclusion of a variable aperture system on the iPhone 18 Pro and 18 Pro Max.

Unlike previous generations’ fixed f/1.78 aperture, the new system would allow users to adjust the amount of light entering the sensor, much like professional DSLRs.

This upgrade could offer better control over depth of field, sharper subject focus, and greater creative flexibility in mobile photography.

3. A20 chip ushers in 2nm era

Leaks about the A20 chip suggest it could represent Apple’s most ambitious tech leap yet. Built on a 2nm process (down from 3nm in the A19), the A20 could increase performance by 15% while reducing power consumption by 30%.

This would not only make the iPhone 18 series the fastest and most power-efficient smartphones available but also solidify Apple’s position in AI processing at the device level.

4. Transparent back panel design

An intriguing leak points to a partially transparent back on the iPhone 18 Pro, allowing users to glimpse some of the device’s internal components.

This design could highlight Apple’s vapor chamber cooling system - first introduced with the iPhone 17 Pro - adding both visual appeal and a hint of technical sophistication.

The look would break from Apple’s typically reserved design language and offer a bolder, symbolic aesthetic.

5. Slimmer Dynamic Island

Dynamic Island, once hailed as Apple’s new design signature, may be slimmed down on the iPhone 18.

Reports suggest a narrower, pill-shaped cutout is in development, enabled by more compact sensors and a smaller front camera. This would increase usable screen space and offer a more refined visual experience.

6. Under-display Face ID could finally arrive

After years of speculation, the iPhone 18 Pro could be the first model to feature fully hidden Face ID sensors beneath the display.

This would allow for ultra-thin bezels and a completely edge-to-edge front design, with only a small punch-hole for the selfie camera.

Display analyst Ross Young - known for accurate Apple display predictions - believes under-display Face ID is likely in 2026, lending credibility to this rumor.

7. Punch-hole selfie camera replaces the notch

If the leaks hold true, Apple may eliminate the notch entirely on the iPhone 18 Pro models, replacing it with a sleek punch-hole camera.

Meanwhile, light and proximity sensors would be moved beneath the display. This would be Apple’s most visible aesthetic shift since the iPhone X introduced the notch in 2017.

8. Camera Control button might be discontinued

The Camera Control button, first introduced with the iPhone 16, may be on the chopping block.

Reports indicate it hasn’t garnered much user engagement, and its production cost remains high. This would be a reminder that not all new features survive, even when launched with fanfare.

9. Apple’s first foldable iPhone could debut

Finally, the biggest rumor of all: the iPhone Fold. Several insiders believe Apple may unveil its first foldable phone alongside the iPhone 18 Pro in fall 2026, though others expect a spring 2027 release.

This model is said to feature a horizontal “book-style” fold with a titanium hinge and a seamless crease-free display.

Expected specs include 12GB RAM, 256GB storage, a 48MP dual camera system, and an under-display selfie camera, with a starting price around USD 2,000.

If realized, the iPhone Fold would be one of Apple’s most iconic devices since the original iPhone - ushering in a new generation of Apple mobility.

With sweeping changes in design, performance, cameras, and display technology, the iPhone 18 Pro is poised to be Apple’s biggest breakthrough of the decade.

While it’s still early and not all rumors may materialize, even if half of them prove accurate, 2026 could indeed be Apple’s golden year.
