From 2nm chip to bigger battery: 9 iPhone 18 Pro upgrades to know

If you are considering buying an iPhone 17 Pro, waiting a few weeks could make more sense. Apple is expected to unveil the iPhone 18 Pro and iPhone 18 Pro Max in September, and current leaks point to several meaningful upgrades rather than a simple yearly refresh. Apple has not confirmed the launch date or specifications, but September 8 or 9 are currently among the reported possibilities.

Here are nine changes that could make the wait worthwhile

1. A new 2nm A20 Pro chip

The biggest internal upgrade could be Apple's A20 Pro, reportedly built using TSMC's 2nm process. The smaller process should help improve performance and power efficiency, which could benefit gaming and on-device AI.

2. Apple's C2 modem

Apple is expected to continue replacing third-party modem technology with its own. The C2 modem could improve connectivity while reducing power consumption. Some reports also suggest Apple is exploring broader satellite connectivity.

3. A smaller Dynamic Island

The front of the iPhone could look cleaner. Reports suggest Apple may reduce the size of the Dynamic Island, with under-display Face ID technology potentially helping free up screen space. Whether Apple can achieve the full change this year remains uncertain.

4. The camera could get a major hardware change

The 48MP main Fusion camera is widely rumoured to gain a variable aperture. Unlike the fixed aperture on recent Pro models, the lens could physically adjust how much light reaches the sensor. That could mean better control in bright and dark scenes, as well as greater control over background blur and depth of field.

5. Better telephoto photography

Apple could also give the telephoto camera a wider aperture and improve its optics. That could be particularly useful when shooting subjects in low light or using zoom.

6. A simpler Camera Control

The Camera Control introduced with the iPhone 16 could be redesigned. Reports suggest Apple may remove some of its touch-sensitive components while retaining the main camera controls, potentially making it easier to use.

7. More efficient displays

The Pro models are expected to retain 6.3-inch and 6.9-inch OLED displays, but could move to an improved LTPO+ technology. The main benefit may be efficiency, helping the phone reduce power consumption.

8. A bigger Pro Max battery

The iPhone 18 Pro Max could receive a particularly noticeable battery upgrade. Current reports suggest a capacity of around 5,567mAh for US models, compared with 5,088mAh for the US iPhone 17 Pro Max. Combined with the 2nm chip and C2 modem, that could translate into longer real-world battery life.

9. Satellite connectivity could go further

Apple already offers satellite-based emergency features. The next step could be satellite connectivity capable of supporting more than emergency communication, although availability would depend heavily on network infrastructure and regional support.

Should you wait for iPhone 18 Pro?

For existing iPhone 17 Pro owners, the upgrade may not be essential. But for someone about to buy a new Pro iPhone, the combination of a 2nm chip, variable-aperture camera, larger battery, smaller Dynamic Island and C2 modem could make waiting worthwhile. There is one big catch: none of these specifications are officially confirmed by Apple yet. The launch date, pricing and final feature list could still change.
