iPhone 17 Pro Max vs Samsung S26 Ultra: 7 Rounds of Test Results and Which One to Buy in 2026

The iPhone 17 Pro Max and the Samsung Galaxy S26 Ultra are the two biggest, most expensive mainstream phones you can buy in 2026, and on paper they look closer than ever: both have 6.9-inch 120Hz screens, 12GB of RAM, IP68 dust and water resistance and at least one telephoto lens. In use they split cleanly. The S26 Ultra is faster in multi-core tests, charges quicker and has the more flexible camera. The iPhone 17 Pro Max lasts longer on a charge and starts $100 cheaper.

We do not run our own lab tests, so this comparison pulls together official specifications and the published results of independent reviewers, mainly Tom's Guide's head-to-head testing and PhoneArena's spec and benchmark comparison. Where sources disagree we say so. Prices are US launch prices.

iPhone 17 Pro Max vs Galaxy S26 Ultra: Quick Verdict

Specs and Price Compared

The price gap grows as you add storage. At 1TB the iPhone is $1,599 and the Samsung is $1,799.99, a $200 difference, and only Apple offers a 2TB model. Samsung's phones tend to drop faster after launch, though: the S26 Ultra has regularly sold well below list price since spring, which can erase the gap. Our analysis of when smartphone prices will drop explains what is pushing prices up and when discounts are likely.

Battery Life and Charging Speed

Apple's switch to a larger battery in the eSIM-only US model paid off. In Tom's Guide's battery test, which loops web browsing over cellular at a fixed brightness, the iPhone 17 Pro Max averaged 17 hours 54 minutes against 16 hours 40 minutes for the S26 Ultra. PhoneArena's separate tests put the two much closer, with the iPhone ahead by only a couple of minutes, so treat the iPhone's lead as real but modest.

Charging flips the result. With 60W wired charging, the S26 Ultra reached 41% in 15 minutes and 77% in 30 minutes, while the iPhone's 40W charging managed 35% and 64%. Both support 25W wireless charging, but only the iPhone has magnets built in, so the Samsung needs a magnetic case to snap onto Qi2 chargers and accessories. If you are not sure what that standard means, read our explainer on Qi2 wireless charging.

Performance: A19 Pro vs Snapdragon 8 Elite Gen 5

The iPhone edges single-core tasks, which is what most apps feel like day to day, while the Samsung pulls ahead by about 16% in multi-core work and 13% in graphics. PhoneArena found the iPhone holds its graphics performance slightly better over a long session, helped by its first-ever vapor chamber. In practice both phones are far faster than anything you will throw at them; this round matters most to heavy gamers and people who edit video on the phone.

Camera Comparison: Zoom Range vs Consistency

Samsung keeps the most flexible zoom system on any mainstream phone: a 3x lens for portraits and a 50MP 5x periscope that stays sharp well past 10x. Samsung also widened the main camera's aperture to f/1.4 this year, which it says lets in 47% more light than the S25 Ultra. Apple took a different route, putting 48MP sensors behind all three rear lenses, including a 4x telephoto that crops to an 8x view with little loss. Tom's Guide gave its camera round to the S26 Ultra.

Where the S26 Ultra camera wins

• Long zoom: concerts, wildlife and sport at 5x to 10x stay usable.
• Two optical focal lengths instead of one, so 3x portraits do not rely on cropping.
• 200MP mode for heavy cropping in good light.

Where the iPhone 17 Pro Max camera wins

• Video: Apple's colour, stabilisation and editing apps remain the reference for creators.
• Selfies: the 18MP front camera can widen the frame for group shots without rotating the phone.
• Consistency: the same 48MP resolution on every rear lens keeps detail and colour similar as you switch lenses.

Display and Privacy Display

Both screens are excellent and almost equally accurate. Tom's Guide measured peak brightness at 1,899 nits for the iPhone and 1,806 nits for the Samsung, and colour error (Delta-E) at 0.26 and 0.29, a difference you cannot see. The Samsung covers a wider colour range in its Vivid mode. The deciding feature is Samsung's built-in Privacy Display, the first on a phone, which makes the screen hard to read from the side and can be switched on for specific apps. If you work on trains or planes, it replaces a stick-on privacy filter without dimming the screen all the time.

Design, S Pen and MagSafe

The S26 Ultra is the lighter phone at 214g against 233g, and thinner at 7.9mm. Samsung swapped titanium for an aluminum frame this year, as Apple did. The two extras pull in opposite directions: Samsung's S Pen lives inside the phone for notes, signatures and precise editing, while Apple's built-in MagSafe magnets mean wallets, stands and chargers attach without a special case.

Software, AI and Updates: iOS vs One UI

Samsung promises seven years of Android and security updates for the S26 Ultra and ships its widest set of Galaxy AI tools, including call screening, live translation and photo editing. Apple does not promise a fixed number of years, but iPhones have historically received iOS updates for five years or more. For most buyers the real decision is ecosystem, not features: if you rely on iMessage, FaceTime, an Apple Watch or a Mac, the iPhone is the easier choice. Our iPhone vs Android guide covers what switching platforms involves.
