iPhone 18 Pro: What’s New?
Before diving into the individual features, here are the major changes introduced with the iPhone 18 Pro:
- A20 Pro 2nm processor with improved on-device AI performance
- New-generation vapour chamber for improved sustained performance
- 48MP main camera with a physical variable aperture
- 48MP ultrawide and 48MP telephoto cameras
- 30% smaller Dynamic Island on a 6.3-inch 120Hz LTPO-OLED display
- Energy-efficient C2 cellular modem and faster wired charging.
Apple says the A20 Pro can deliver up to 40% faster graphics performance than the A19 Pro, while its new packaging and vapor chamber are designed to improve heat management during demanding workloads.
How Good is the Latest A20 Pro 2nm Processor?
Apple has taken a major performance leap with the iPhone 18 Pro, powered by the new Apple A20 Pro chip built on a 2nm process. For comparison, the iPhone 18 Pro reportedly reaches approximately 3.5 million, and the iPhone 17 Pro scored around 2.3 million in AnTuTu v11.
However, the RedMagic 11 Pro Plus remains ahead in AnTuTu performance. Powered by Qualcomm’s Snapdragon 8 Elite Gen 5 (3nm), it reportedly achieves a massive 4.1 million score. The Samsung Galaxy S26, powered by the Exynos 2600 (2nm), follows with approximately 3.1 million.
Flagship Performance Comparison
| Smartphone | Processor | AnTuTu v11 Score | Geekbench 6 (Single-Core) | Geekbench 6 (Multi-Core) |
|---|---|---|---|---|
| iPhone 18 Pro | A20 Pro (2nm) | ~3,500,000 | ~4,100 | ~11,000 |
| RedMagic 11 Pro Plus | Snapdragon 8 Elite | ~4,100,000 | ~3,500 | ~11,000 |
| Galaxy S26 | Exynos 2600 (2nm) | ~3,100,000 | ~3,200 | ~11,500 |
| iPhone 17 Pro Max | A19 Pro (3nm) | ~2,500,000 | ~3,400 | ~10,000 |
Geekbench 6 tells a different story, showcasing Apple’s dominance in raw CPU performance. The iPhone 18 Pro takes a commanding lead in single-core metrics.
Benchmark results can vary depending on software version, temperature, testing conditions, and device configuration.
What’s Changed in the Camera?
Apple introduced a true physical variable aperture on its main camera, utilizing six laser-cut polymer composite blades that physically open and close to control light. This hardware upgrade only applies to the primary 48-megapixel camera, allowing users to adjust the aperture manually or automatically between f/1.48, f/1.8, f/2.8, and f/4.0.
Aside from this change, most of the rear camera hardware remains virtually identical to the previous generation. The device retains its triple-lens setup, which includes the new variable-aperture main sensor, a 100mm periscope telephoto camera (f/2.8), and an ultrawide camera (f/2.2).
For videographers, the iPhone 18 Pro continues to support 4K recording at up to 120 fps alongside Dolby Vision HDR and ProRes RAW workflows. The standout addition this year is the introduction of Cinematic Mode tuning for standard video, giving creators seamless, granular control over exposure and color grading in real time.
What’s New in the Display?
The display panel hardware remains virtually identical to the iPhone 17 Pro, and the only notable change is a 30% smaller Dynamic Island. It features a 6.3-inch Super Retina XDR LTPO OLED screen, with a 1Hz to 120Hz refresh rate, Dolby Vision, HDR10, and a peak brightness of 3000 nits with an anti-reflective coating.
My Take: As someone who dislikes aggressive screen cutouts, I highly appreciate Apple shrinking the Dynamic Island. While it sounds minor on spec sheets, it makes full-screen gaming and streaming noticeably less obstructed in landscape mode.
iPhone 18 Pro: Battery and Improved Performance
It comes with a 4,056 mAh battery in the Nano-SIM model and a 4,288 mAh battery in the eSIM models. This represents only a modest increase over last year’s model, with gains of approximately 58 mAh and 30 mAh, respectively.
However, with the 2nm Apple A20 Pro chip, hardware performance has improved by 25% to 30% because the newer processor consumes less energy compared to the previous 3nm based processor. It delivers up to 34 hours of video playback, and the Apple C2 Modem consumes 15% less energy than the previous-gen C1X chip.
For charging, the device reaches a 50% charge in 20 minutes on a standard fast charger, dropping to just 15 minutes if you use a 60W adapter supporting Adjustable Voltage Supply (AVS).
Who Should Buy the iPhone 18 Pro?
The iPhone 18 Pro is an excellent investment for specific types of users. It is the ideal choice if:
- Users upgrading from iPhones 15 Pro or older: The A20 Pro, improved efficiency, battery life, display, and camera capabilities make it a significant upgrade from older generations.
- Power users and gamers: The improved performance and efficiency of the 2nm A20 Pro make it suitable for demanding games, video editing, and other intensive workloads.
- Content creators: The combination of the Pro camera system, high-quality OLED display, powerful processor, and strong video capabilities makes it well suited for photo and video creation.
- Users who prioritize battery life: Although the battery-capacity increase is relatively small, improvements in processor, modem, and display efficiency can help extend overall battery endurance.
- Long-term iPhone users: Those looking for a flagship they can keep for several years can benefit from Apple’s powerful silicon, long-term software support, and premium hardware.
Who Should Avoid the iPhone 18 Pro?
While the iPhone 18 Pro is a technological marvel, it might not be the right choice for everyone. You may want to skip this generation if:
- You prefer open software systems: If you want deep UI customization, easy app sideloading, or advanced file management, iOS 20 will still feel too restrictive compared to Android
- You already own an iPhone 17 Pro: The performance gap between the A19 Pro and the A20 Pro will not be noticeable in everyday tasks, and the display hardware remains virtually identical.
- You are on a budget: Starting at $1,199 / ₹1,64,900, this is a major financial investment that offers diminishing returns if you do not need pro-level video features.
- You want maximum raw graphics performance: Gamers looking for absolute peak benchmark scores may prefer Android flagships powered by the Snapdragon 8 Elite, which outpaces the A20 Pro in raw AnTuTu metrics.
Final Verdict
Apple iPhone 18 Pro gets a meaningful refinement over its predecessor that focuses on performance, efficiency, battery life, and overall usability rather than a complete redesign. The new A20 Pro, a 2nm chip, brings substantial performance and efficiency, with a more power-efficient C2 modem and LTPO OLED display further helping reduce power consumption.
Although the battery size increase itself is relatively small, the combination of improved silicon efficiency combined with other modem and display panel optimization allows the iPhone 18 Pro to deliver up to 30-plus hours of video playback. The fast charging capabilities make it more convenient for users who frequently rely on their smartphone throughout the day.
