Apple has revealed some of the biggest upgrades coming to the iPhone 18 Pro and iPhone 18 Pro Max, including a new 2nm A20 Pro chip, longer battery life and expanded Apple Intelligence features. The iPhone 18 Pro offers up to 36 hours of battery life, while the iPhone 18 Pro Max reaches up to 45 hours, making it the longest-lasting model in the new Pro lineup.
The new Burgundy finish also joins Black, Silver and Glacier, giving buyers four colour options.
How long does the iPhone 18 Pro battery last?
Apple says the iPhone 18 Pro can deliver up to 36 hours of battery life, while the larger iPhone 18 Pro Max reaches up to 45 hours.
| Model | Battery life |
|---|---|
| iPhone 18 Pro | Up to 36 hours |
| iPhone 18 Pro Max | Up to 45 hours |
The 45-hour figure makes the Pro Max particularly interesting for people who prioritise battery endurance. It also gives Apple a strong selling point against users who find themselves charging their phones frequently.
However, “up to” battery figures depend on usage and testing conditions, so real-world battery life can vary.
What chip does the iPhone 18 Pro use?
The iPhone 18 Pro and iPhone 18 Pro Max are powered by Apple's new 2nm A20 Pro chip.
Apple says the A20 Pro features a six-core CPU that is up to 20% faster, alongside a seven-core GPU that delivers up to 40% better graphics performance. The chip also brings 50% higher memory bandwidth.
| A20 Pro specification | Apple’s claim |
|---|---|
| Manufacturing process | 2nm |
| CPU | Six-core |
| CPU performance | Up to 20% faster |
| GPU | Seven-core |
| Graphics performance | Up to 40% better |
| Memory bandwidth | 50% higher |
These improvements could matter most for demanding tasks such as gaming, video editing and AI-powered features, where both processing power and memory bandwidth can have a noticeable impact.
What new Apple Intelligence features are coming to the iPhone 18 Pro?
Apple is expanding Apple Intelligence with additional Siri capabilities and system-wide AI improvements.
One of the notable additions is Siri integration within the Camera app, potentially making it easier for users to interact with camera-related functions through natural language.
Apple is also introducing more expressive Siri voices, along with enhanced system-wide dictation.
The broader direction is clear: Apple is trying to make AI feel less like a separate feature and more like something built into everyday iPhone interactions.
Will the new Siri AI features work in India?
Based on Apple's announcement, the new Siri AI features will not be available in the European Union and China.
India is not included in those restrictions based on the information currently available.
However, Apple may roll out individual Apple Intelligence capabilities at different times depending on language, region and regulatory requirements, so users should check Apple's India availability details for specific features.
What colours does the iPhone 18 Pro come in?
Apple has introduced four finishes for the iPhone 18 Pro and iPhone 18 Pro Max:
- Black
- Silver
- Glacier
- Burgundy
The new Burgundy finish is one of the most noticeable additions, giving Apple's Pro lineup a darker and more distinctive appearance.
Glacier, meanwhile, offers a lighter alternative for buyers who don't want the traditional Black or Silver finishes.
Is the iPhone 18 Pro Max better than the iPhone 18 Pro?
The biggest confirmed advantage highlighted so far is battery life.
The iPhone 18 Pro Max offers up to 45 hours compared with up to 36 hours on the iPhone 18 Pro. Both models receive the new A20 Pro chip and the expanded Apple Intelligence features.
| Feature | iPhone 18 Pro | iPhone 18 Pro Max |
|---|---|---|
| Chip | A20 Pro | A20 Pro |
| CPU | Six-core | Six-core |
| GPU | Seven-core | Seven-core |
| Battery life | Up to 36 hours | Up to 45 hours |
| Colours | Black, Silver, Glacier, Burgundy | Black, Silver, Glacier, Burgundy |
| Apple Intelligence | Yes | Yes |
For someone who wants maximum battery endurance, the Pro Max looks like the obvious choice. Buyers who prefer a smaller Pro model still get the same new-generation chip and AI features.
Why is the 2nm A20 Pro chip important?
Moving to a 2nm process is significant because chip manufacturing improvements can help manufacturers balance performance and power efficiency.
In the A20 Pro, Apple is pairing the newer process with claimed CPU, GPU and memory-bandwidth improvements. That combination could be particularly useful as Apple pushes more AI processing directly onto its devices.
The important takeaway isn't simply that the chip is “faster.” Apple's hardware strategy is increasingly tied to handling computationally demanding features locally, including AI.
What does this mean for iPhone 18 Pro buyers?
The iPhone 18 Pro generation is shaping up around three major selling points: performance, battery life and AI.
The A20 Pro brings substantial claimed performance improvements, while the Pro Max's 45-hour battery rating targets one of the biggest concerns for heavy smartphone users. Meanwhile, Apple's Siri and dictation updates show that the company is continuing to make AI a central part of the iPhone experience.
For buyers deciding between the two models, the choice may ultimately come down to size and battery endurance rather than core processing capabilities.
