Apple is expected to reveal its next-generation Pro iPhones at its September 9 event.

Meanwhile, current iPhone 18 Pro Max rumors point toward an A20 Pro chip, a larger battery, upgraded cameras, and a smaller Dynamic Island.

That means you should not think of every iPhone 18 model as a direct competitor to the Galaxy S26 Ultra.

Display: iPhone 18 Pro Max vs Samsung S26 Ultra
The display battle could be extremely close.
The Galaxy S26 Ultra has a huge 6.9-inch QHD+ Dynamic AMOLED 2X display with a 1–120Hz adaptive refresh rate. Samsung also added a built-in Privacy Display, which is designed to make the screen harder for people beside you to see.
The iPhone 18 Pro Max is rumored to keep a 6.9-inch OLED display with 120Hz ProMotion.
Some reports also point toward a smaller Dynamic Island, while the display resolution is expected to remain around 2868 × 1320.
Winner for now: Samsung Galaxy S26 Ultra
Why?
Because Samsung’s display specifications are confirmed, and the Privacy Display is a feature Apple does not currently offer in the same way.
However, the iPhone 18 Pro Max could close the gap once Apple officially reveals it.
Performance: A20 Pro vs Snapdragon 8 Elite Gen 5
This could be one of the most interesting parts of the iPhone 18 Pro Max vs S26 Ultra comparison.
Samsung uses the Snapdragon 8 Elite Gen 5 for Galaxy, a customized 3nm processor designed specifically for Galaxy devices. Samsung says the chip brings major CPU, GPU and NPU improvements compared with the previous generation.
Apple’s upcoming A20 Pro is rumored to use a new 2nm manufacturing process.
Some reports claim improvements in performance and power efficiency, but these numbers should not be treated as official until Apple provides them.
Which is faster?
Right now, Samsung has the advantage of being a real, tested product.
But if the reported A20 Pro improvements are accurate, the iPhone 18 Pro Max could become one of the fastest smartphones of 2026.
Winner: iPhone 18 Pro Max — potential winner, but not confirmed yet
Camera: iPhone 18 vs S26 Ultra
If camera hardware is your priority, Samsung has a serious advantage on paper.
The Galaxy S26 Ultra features:
- 200MP main camera
- 50MP ultrawide
- 50MP 5x telephoto
- 10MP 3x telephoto
- Up to 100x digital zoom
- 8K video recording
- 4K 120fps Pro Video
Samsung also uses its ProVisual Engine for image processing and low-light photography.
The iPhone 18 Pro Max is rumored to use three 48MP rear cameras, with a variable-aperture camera potentially becoming one of its biggest upgrades.
That could help Apple improve control over light and depth while taking photos.

Potential winner for video and computational photography: iPhone 18 Pro Max
Battery Life and Charging
Battery life could be another major reason to wait for the new iPhone.
The Galaxy S26 Ultra has a confirmed 5,000mAh battery and supports up to 60W wired charging. Samsung says the phone can reach around 75% charge in approximately 30 minutes under its stated conditions.
For the iPhone 18 Pro Max, reports indicate Apple could significantly increase battery capacity compared with the iPhone 17 Pro Max. One leak claimed an increase of nearly 12%.
However, battery capacity alone does not tell the whole story.
Apple controls both the processor and operating system, which means an iPhone can sometimes achieve excellent battery life without having the largest battery.

Winner: Too close to call until the iPhone 18 Pro Max is officially tested
RAM and Storage
Samsung gives buyers three storage options:
- 256GB with 12GB RAM
- 512GB with 12GB RAM
- 1TB with 16GB RAM
These are confirmed specifications.
The iPhone 18 Pro Max is rumored to retain around 12GB RAM and could offer storage configurations reaching 2TB.
But remember:
More RAM does not automatically mean better performance.
Apple and Samsung use different operating systems and memory-management systems, so comparing RAM numbers directly can be misleading.
Winner for maximum storage: iPhone 18 Pro Max, if the 2TB rumor is accurate
Winner for confirmed configurations: Samsung
AI and Software
The software experience is one of the biggest differences between these phones.
The Galaxy S26 Ultra runs Android with Samsung’s Galaxy AI features, including tools for photography, productivity and editing.
The phone also supports Samsung DeX and the S Pen, making it more useful as a productivity device.
Apple’s upcoming iPhone generation is expected to build on Apple Intelligence and Apple’s newer AI features.
This could make the iPhone particularly attractive if you already use a Mac, iPad, Apple Watch or AirPods.
Best for productivity and multitasking: Galaxy S26 Ultra
Best for Apple ecosystem users: iPhone 18 Pro Max
Price: iPhone 18 Pro Max vs S26 Ultra
Price could become one of the biggest surprises.
The Galaxy S26 Ultra’s U.S. starting price is around $1,299, depending on configuration and promotions.
For the iPhone 18 Pro and Pro Max, current reports suggest Apple could increase prices compared with previous Pro models. A September 3 report citing TrendForce estimates suggested higher pricing for the upcoming Pro models.
That means the iPhone 18 Pro Max could potentially cost more than the Galaxy S26 Ultra.

iPhone 18 vs Samsung Galaxy S26 Ultra: Frequently Asked Questions
Is iPhone 18 better than Samsung Galaxy S26 Ultra?
It is too early to declare the iPhone 18 better because Apple has not officially announced the iPhone 18 Pro Max as of September 3, 2026. The Galaxy S26 Ultra is already available and has confirmed specifications. The iPhone could have an advantage in performance and efficiency if the A20 Pro rumors are accurate.
Which has the better camera, iPhone 18 or S26 Ultra?
The Galaxy S26 Ultra currently has the more versatile camera hardware, including a 200MP main camera and two telephoto cameras. The iPhone 18 Pro Max is rumored to have three 48MP cameras and a variable-aperture system, so the final comparison should wait for Apple’s official announcement and camera tests.
Will iPhone 18 Pro Max have better battery life?
It could. Multiple reports point toward a larger battery for the iPhone 18 Pro Max, but real-world battery life depends on software, processor efficiency and display behavior. Therefore, the larger rumored battery does not guarantee longer battery life.
Is Galaxy S26 Ultra worth buying in 2026?
Yes. If you need a flagship phone today, the Galaxy S26 Ultra is one of the strongest choices available. Its 6.9-inch 120Hz display, 200MP camera system, Snapdragon 8 Elite Gen 5, S Pen and Privacy Display give it a very strong feature set.
Should I wait for iPhone 18 Pro Max?
If you are already using a good phone and do not need to upgrade immediately, waiting makes sense. Apple’s September 9 event is very close, so you will soon have official information instead of relying on leaks.
Which is better for gaming?
Both should be extremely powerful. Samsung already offers the Snapdragon 8 Elite Gen 5 for Galaxy, while the iPhone 18 Pro Max is expected to use Apple’s A20 Pro. The final gaming winner should be determined by independent performance and sustained-thermal testing after the iPhone launches.
iPhone 18 Pro Max or Galaxy S26 Ultra: Which should you buy?
If you need a phone today, choose the Galaxy S26 Ultra.
If you want the newest Apple flagship and can wait, the iPhone 18 Pro Max is worth watching closely.
Final Verdict: iPhone 18 vs Samsung Galaxy S26 Ultra
The iPhone 18 vs Samsung Galaxy S26 Ultra comparison is not completely fair yet because one phone is confirmed and available while the other is still waiting for its official unveiling.
Samsung currently wins on confirmed camera hardware, zoom flexibility, S Pen functionality, display features, and immediate availability.
Apple could fight back with the rumored A20 Pro chip, larger battery, variable-aperture camera, smaller Dynamic Island, and improved Apple Intelligence features.
So here is my recommendation:
Need a flagship now? Buy the Galaxy S26 Ultra.
Already have a good phone? Wait for the iPhone 18 Pro Max announcement.
Want the best Apple ecosystem experience? Wait for iPhone 18 Pro Max.
Want maximum features and flexibility today? Galaxy S26 Ultra is the safer choice.
Most importantly, don’t buy based only on leaks. Apple’s September 9 event should turn many of these iPhone 18 rumors into confirmed specifications. Once that happens, the real iPhone 18 Pro Max vs Samsung Galaxy S26 Ultra battle can finally begin.
