iPhone 18 Pro Max vs Galaxy S26 Ultra: Which Flagship Wins

Apple's latest Pro Max and Samsung's Ultra sit at the top of their lineups this year. Here's how they stack up.

Display and design

The iPhone 18 Pro Max has a 6.9-inch display and comes in Burgundy, Glacier blue, Silver and Black, with the same familiar iPhone design as last year, just slightly heavier. The Samsung Galaxy S26 Ultra measures 163.6 x 78.1 x 7.9mm at 214g, built with a Corning Gorilla Armor 2 front, Gorilla Glass Victus 2 back, and an aluminum frame, and is IP68 rated. It ships in six colors, including Cobalt Violet and Sky Blue, and includes a built-in S Pen stylus, something the iPhone doesn't offer.

Camera

On paper, the Galaxy S26 Ultra looks like the clear winner, with a 200MP main sensor against the iPhone's 48MP. But real-world results tell a different story. The iPhone 18 Pro Max's new variable aperture, shifting between f/1.48 and f/4.0, gives it a real edge in low light, handling dim scenes noticeably better than the S26 Ultra.

For video, results go back and forth, sometimes Samsung wins a shot, sometimes Apple does, but the iPhone is the more consistent performer overall, especially in low light.

In good lighting, still photos from both phones are barely distinguishable. Samsung continues to lean toward cooler tones, while iPhone photos lean warmer, and this year's iPhone shots surprisingly show strong contrast and fine detail. Across both good and low light, still photos from the two phones end up nearly identical in quality. Where Samsung pulls ahead is zoom, its dual telephoto system produces cleaner, sharper results at a distance than the iPhone can match.

Performance and battery

The iPhone 18 Pro Max runs Apple's new A20 Pro chip, now paired with a larger vapor chamber for improved cooling and more sustained performance under load. The S26 Ultra runs a higher-clocked Snapdragon 8 Elite Gen 5 "for Galaxy" chip, with Super Fast Charging 3.0 at up to 60W wired and 25W wireless.

Battery life is a surprising win for Apple this year. The iPhone 18 Pro Max lasts about 2 hours longer than the S26 Ultra in real-world use, despite similar battery capacities, a gap most didn't expect going in.

Software

The S26 Ultra leans heavily on Galaxy AI, including a Privacy Display feature and AI tools built to anticipate what the user needs next. The iPhone 18 Pro Max runs on Apple's more contained approach to on-device AI, with fewer flashy additions but a more consistent experience across the system.

Price

The iPhone 18 Pro Max starts at $1,299 for 256GB. The Samsung Galaxy S26 Ultra also starts at $1,299 for 256GB, with 512GB and 1TB options priced higher than last year's equivalents.

The bottom line

Both phones start at the same price and deliver capable cameras and top-tier chips. Samsung wins on zoom and specs on paper, Apple wins on low light, video consistency, cooling and battery life, and daytime photos are close to a wash between them. The choice mostly comes down to preference, and which ecosystem, iOS or Android, fits your life better.
