iPhone 18 Pro Max vs Galaxy S26 Ultra: Camera, Battery and Performance Compared

If you are spending well over a thousand dollars on a phone this year, the shortlist usually comes down to two names. Apple has the iPhone 18 Pro Max, which arrived in September 2026 with a new 2nm chip and a camera that can physically change its aperture. Samsung has the Galaxy S26 Ultra, which launched in March 2026 with the fastest Snapdragon chip it has ever used, a 200MP camera and a clever Privacy Display that nobody else offers.

Both phones are excellent. The question is which one fits the way you actually use a phone. We went through the specs, the independent reviews and the real world battery tests so you do not have to.

Quick verdict

Buy the iPhone 18 Pro Max if you want the longest battery life Apple has ever shipped, the fastest chip in any phone right now, and a camera that behaves more like a real camera thanks to its variable aperture and new Pro controls.

Buy the Galaxy S26 Ultra if you want the more flexible zoom setup, the built in S Pen, a sharper QHD+ screen with privacy mode, and a bit more control over how your phone looks and works.

Specs at a glance

Design and display

Apple did not change much on the outside this year. The iPhone 18 Pro Max looks almost identical to last year’s model, though the Dynamic Island at the top of the screen is now a little smaller. The bigger complaint from reviewers is weight. PhoneArena called it a heavyweight phone, and if you have small hands that is worth knowing before you buy.

Samsung went the other way and made the S26 Ultra thinner and lighter than the S25 Ultra. It still has the flat, squared off Ultra shape and the S Pen tucked into the bottom, which is still the only stylus you will find built into a mainstream flagship.

Both phones have 6.9 inch screens, but the Samsung panel runs at a higher QHD+ resolution of 3120 by 1440 and can drop all the way down to 1Hz to save power. The headline feature here is the Privacy Display. With one tap, the screen narrows its viewing angle so the person sitting next to you on a train cannot read your messages or banking app. Engadget said this feature should be standard on all premium phones, and it is genuinely useful. There is a trade off though: Tom’s Guide measured the S26 Ultra as dimmer than the S25 Ultra, and Samsung has acknowledged some variation in image quality at certain viewing angles, even with Privacy Display switched off.

The iPhone screen is still one of the most color accurate you can buy, and it is bright enough for any sunny day. But if we are only judging the display, Samsung wins this round.

Performance

This is where things get interesting. The A20 Pro is the first 2nm chip ever used in an iPhone, and Tom’s Guide called the iPhone 18 Pro Max the fastest phone ever, with record breaking speed that beats every Android flagship. Apple also added a larger vapor chamber for cooling, so the phone holds its top speed longer during gaming and video exports.

The Galaxy S26 Ultra is no slouch. Its Snapdragon 8 Elite Gen 5 for Galaxy is an overclocked version with two cores running at 4.74GHz, and Samsung says it delivers 19% faster CPU performance, around 24% faster graphics and a 39% faster NPU for AI tasks compared to the S25 Ultra. Notebookcheck found it stays fairly cool in daily use, but it does throttle noticeably under long, heavy loads.

In daily use you will not feel a difference opening apps or scrolling social media. Where Apple pulls ahead is sustained heavy work like 4K video editing and demanding games over long sessions.

Cameras

The biggest camera change in years for the iPhone is the variable aperture on the 48MP main camera. It can open up to f/1.48 to pull in more light at night, or close down to f/4.0 when you want more of the scene in focus, like a group photo or a landscape. Apple also finally added Pro controls in the stock camera app, so you can adjust settings manually without downloading a third party app. Reviewers at The Shortcut called the variable aperture a big deal, and it is the main reason camera fans will upgrade.

Samsung’s approach is about range. The 200MP main sensor now has a wider f/1.4 lens that captures around 47% more light than before, and you get two telephoto cameras: a 3x and a 5x. That makes portrait shots at different distances very easy, and the 5x lens is great at concerts and sports. Samsung also improved night photos and made the camera faster to respond.

For video, the iPhone remains the safer choice. Its footage is consistent across all three lenses, and features like ProRes and Log recording make it the phone many creators trust. For still photos, it honestly depends on taste. iPhone photos look natural and true to life. Samsung photos tend to be brighter and punchier, which many people prefer for social media.

Battery life and charging

Here Apple has made a real leap. The US eSIM version of the iPhone 18 Pro Max has a roughly 5,567mAh battery, the biggest ever put in an iPhone, and Apple rates it for up to 45 hours of video playback, up from 39 hours last year. On the Tom’s Guide battery test, which involves nonstop web browsing over 5G, it averaged 18 hours and 27 minutes, compared with 16 hours and 40 minutes for the Galaxy S26 Ultra. In PhoneArena’s YouTube playback test the gap was even wider, at 12 hours 6 minutes for the iPhone against 9 hours 36 minutes for the Samsung.

The Galaxy S26 Ultra keeps a 5,000mAh battery. That is still comfortably a full day for most people, but it does trail the iPhone in every independent test we found. Where Samsung wins is charging: 60W wired and 25W wireless, up from 45W and 15W on the S25 Ultra.

If battery life is your top priority, the iPhone 18 Pro Max is the clear winner this year.

Software and updates

iOS 27 brings a refreshed interface and expanded Siri AI features, and Apple typically supports its phones for six to seven years. Samsung promises seven years of Android and security updates on the S26 Ultra, and Galaxy AI features like live translation, note summaries and photo editing tools are deeply built into One UI.

The real deciding factor here is ecosystem. If you own a Mac, an Apple Watch or AirPods, the iPhone simply works better with them. If you use Windows, a Galaxy Watch or Galaxy Buds, the Samsung makes more sense.

Price and value

Both phones start at basically the same price of around $1,299 for 256GB. Apple raised its prices by $100 this year, while Samsung kept the S26 Ultra price the same as last year. Samsung phones also tend to get discounted faster after launch, and carrier deals on the S26 Ultra have been very aggressive.

One advantage for Apple: if you shoot a lot of 4K or ProRes video, you can get the iPhone with up to 2TB of storage. Samsung tops out at 1TB.

Which one should you buy?

Choose the iPhone 18 Pro Max if battery life, raw speed, video recording and the Apple ecosystem matter most to you. It is the most well rounded iPhone Apple has ever made, as long as you do not mind the weight.

Choose the Galaxy S26 Ultra if you want the better screen, two zoom lenses, the S Pen and the Privacy Display. It is the more feature packed phone and often the better deal once discounts kick in.

You really cannot go wrong with either one. Pick the ecosystem you already live in, and you will be happy for years.

What People Are Saying

Beyond professional reviews, we looked at what owners and buyers are discussing on Reddit, the Samsung Community forum, MacRumors and GSMArena. These are opinions and early impressions from real users, not lab tests, so treat them as extra context rather than hard facts.

Privacy Display splits Galaxy owners

The most talked about issue on the Samsung side is the screen. Several Reddit users said the S26 Ultra display gave them eye strain or looked fuzzy next to their old phone, and one said they were returning it. Plenty of other owners in the same threads reported no problems at all, and TechRadar did not see the issue in its own review. (Source)

On the Samsung Community forum, a user upgrading from an S23 Ultra said text looked oversharpened on the new phone, while PhoneArena noted that an equally large group of owners say the screen is fine. (Source)

Some S26 Ultra buyers wanted a bigger battery

In GSMArena’s user reviews, a common complaint is that Samsung kept the same 5,000mAh capacity for another year while rivals moved to much larger cells. Others pushed back, saying battery life and charging speed felt better than on their previous Ultra. One owner suggested that S25 Ultra users can skip this generation unless they really want the Privacy Display. (Source)

iPhone buyers love the battery, not the weight

Battery life is the upgrade iPhone 18 Pro Max owners mention most, and independent tests back them up. The main complaint is weight. At 249g it is the heaviest non folding iPhone Apple has made, and one Reddit owner said it felt noticeably heavier in the hand than the 17 Pro Max, especially once a case and screen protector were added. (Source)

The common advice

Across forums, the advice is consistent. If battery life and video matter most, buyers lean towards the iPhone 18 Pro Max. If you want the S Pen, two zoom lenses and faster charging, the S26 Ultra is the pick, but try the screen in a store first if you are sensitive to eye strain.
