The Quick Verdict
The iPhone 18 Pro Max is the better phone. The Galaxy S26 Ultra is the better buy. It wins on speed, battery and video; the Samsung costs about $380 less today, reaches 100x zoom, charges in 43 minutes and comes with a stylus.
That price gap is the whole story, and it exists for a boring reason: the S26 Ultra has been on sale since 11 March 2026 and the iPhone has been on sale since 18 September. Launch reviews never mention it because when they are written, it is not true yet.
Before going further: some of the numbers below come from different labs running different protocols. Where that is the case we say so instead of putting two incomparable figures side by side and declaring a winner.
The $380 Question
Smartprix lists the Galaxy S26 Ultra at around $914.97 as of September 2026, against a $1,299.99 launch price. The iPhone 18 Pro Max starts at $1,299 per Apple and, three days into its life, is not discounted anywhere.
So the real question is not "which phone is better". It is "is the iPhone's lead worth $380?" For most people the answer is no. For some - heavy video shooters, people who genuinely run out of battery - it is yes.
If you are comparing to the previous generation instead, our iPhone 17 Pro Max vs Galaxy S25 Ultra comparison covers the same ground a year earlier, and the discount logic applies there even more strongly.
Performance
Tom's Guide recorded Geekbench 6 scores of 4,719 single-core and 12,677 multi-core for the A20 Pro, calling these the fastest phones it has tested. The Galaxy S26 Ultra returns 3,785 / 11,563.
That is roughly a 25% single-core lead. Apple builds the A20 Pro on a 2nm process with a 6-core CPU, 7-core GPU and dual 16-core Neural Engine, which it says doubles the AI processing of the A19 Pro.
Here is the honest caveat: a 25% CPU lead is invisible when you are scrolling, messaging or taking photos. Both phones are far past the point where speed limits everyday use. It shows up in sustained work - long video exports, large photo batches - and in how long the phone will still feel current in year four.
Battery and Charging
This is the iPhone's clearest genuine win, and it is a win because one outlet tested both phones the same way.
Tom's Guide runs continuous web browsing over 5G at 150 nits. The iPhone 18 Pro Max averaged 18 hours 27 minutes, with a best run of 18:41, and Tom's Guide reports it lasting about two hours longer than the Galaxy S26 Ultra. For context, the iPhone 17 Pro Max managed 17:54 on the same test.
GSMArena separately gives the S26 Ultra an Active Use Score of 16:23h, noting it runs the same 5,000 mAh cell as the S25 Ultra and gains only through software. That 16:23 figure is *not* directly comparable to Tom's Guide's 18:27 - different script, different conditions. Treat them as two independent readings that happen to point the same way.
Charging reverses the result. GSMArena measured the S26 Ultra at 51% in 15 minutes, 84% in 30 minutes, and full in 43 minutes. Apple quotes about 50% in 15 minutes wired but publishes no verified full-charge time, so the iPhone's cell in our table is empty rather than estimated.
Practical read: the iPhone gets you further from the charger, the Samsung gets you off it faster.
Display
Both are 6.9-inch 120Hz OLED panels with an anti-reflective coating, and both drew praise for it.
The measured numbers do not line up, and it is worth explaining why rather than picking a winner:
- iPhone 18 Pro Max, per Tom's Guide: 2,326 nits at a 25% window and 1,762 nits at a 10% window, against Apple's rated 3,000.
- Galaxy S26 Ultra, per GSMArena: 1,480 nits on a 75% white patch in auto mode, and above 2,800 nits on a 10% patch.
The 10% figures look like a rout for Samsung - 2,800 against 1,762 - but these are two different labs using different patches, ramp behaviour and auto-brightness triggers. We are not going to convert one into the other. What both reviews agree on qualitatively is that each panel is legible outdoors and that the new coatings help.
Samsung adds a Privacy Display mode that limits viewing angle, which the iPhone has no equivalent for.
Cameras
Two different bets.
Apple's 48MP Fusion Main uses a mechanical variable aperture - six laser-cut blades moving between f/1.48 and f/4. Wide open for dim scenes, stopped down to keep a group sharp. All three rear cameras are 48MP.
Samsung's answer is resolution and reach: a 200MP main sensor and zoom to 100x. As Engadget puts it, that sensor exists so you can crop hard into it.
What reviewers found in practice:
- Samsung wins distance, decisively. Nothing on the iPhone competes at long zoom.
- Samsung takes ultra-wide detail and macro.
- Apple takes colour and portraits, with a more natural palette.
- Apple takes video, with wider dynamic range.
- In low light, the f/1.48 setting produced the sharper result in side-by-side testing.
One caveat worth repeating from GSMArena: the older S25 Ultra actually does better close-ups than the S26 Ultra, because of its periscope lens. If macro is your priority, the previous generation is worth a look.

Which Should You Buy?
Buy the Galaxy S26 Ultra if you want to keep $380, photograph anything far away, want a stylus, or would rather charge in 43 minutes. You give up about 25% CPU headroom and roughly two hours of screen time, and in daily use you will notice neither as often as you will notice the money.
Buy the iPhone 18 Pro Max if you shoot video seriously, if battery is the thing you currently complain about, if you are locked into Apple's ecosystem tightly enough that $380 is cheaper than switching, or if you simply want the fastest phone on sale and are content to pay launch price.
What should *not* decide it: benchmark scores on their own, or brightness numbers from two different labs. Both phones are fast, both screens are excellent outdoors, and neither of those things is where these two actually differ.

Samsung Galaxy S26 Ultra
The iPhone is the better phone. The S26 Ultra is the better buy.
On the numbers, this is not especially close: the iPhone 18 Pro Max is faster in both Geekbench 6 figures, lasts about two hours longer in the one battery test that ran both handsets, and takes better video. If someone handed you both and asked which is the stronger phone, the honest answer is the iPhone. But you are not being handed both. The S26 Ultra has been on sale since March and now goes for roughly $915, while the iPhone is three days old and sells at its full $1,299. That $380 gap buys a phone that is still fast enough for anything, charges in 43 minutes rather than needing most of an evening, reaches 100x where the iPhone simply cannot, and comes with a stylus. Unless you specifically need the speed, the battery or the video, the Samsung is where the value is right now.
Choose Apple iPhone 18 Pro Max If:
- You shoot a lot of video and want the widest dynamic range available
- Battery life is the thing you complain about most on your current phone
- You are already deep in iMessage, Watch and AirPods and switching would cost you more than $380 in friction
- You want the fastest phone on sale and are willing to pay launch price for it
Choose Samsung Galaxy S26 Ultra If:
- You want to keep roughly $380
- You photograph things that are far away: sports, wildlife, stages, architecture
- You want to write or draw on the screen
- You would rather charge in 43 minutes than wait, and you can live with a phone that is merely very fast
Frequently Asked Questions
Is the iPhone 18 Pro Max faster than the Galaxy S26 Ultra?
Yes, and not narrowly. Tom's Guide recorded Geekbench 6 scores of 4,719 single-core and 12,677 multi-core for the A20 Pro, against 3,785 and 11,563 for the Galaxy S26 Ultra. That is roughly a 25% single-core lead. In practice both phones run everything on the App Store and Play Store without complaint, so the gap matters most for sustained work like video export.
Which has better battery life?
The iPhone, by about two hours. Tom's Guide ran both phones through the same web-browsing test over 5G at 150 nits and the iPhone 18 Pro Max averaged 18 hours 27 minutes. GSMArena separately measured an Active Use Score of 16:23h for the S26 Ultra, but that is a different protocol and should not be subtracted from the Tom's Guide figure.
How much cheaper is the Galaxy S26 Ultra right now?
About $380. The S26 Ultra launched at $1,299.99 in March 2026 and Smartprix lists it at roughly $914.97 as of September 2026. The iPhone 18 Pro Max started shipping on 18 September 2026 at $1,299 and has not discounted.
Does the iPhone 18 Pro Max have a periscope zoom?
No. It carries three 48MP cameras - wide, ultra-wide and telephoto - with no periscope module. The Galaxy S26 Ultra reaches up to 100x and reviewers consistently found it the stronger phone at distance. If you photograph sport, wildlife or stages, this is the difference that should decide it.
What does the variable aperture on the iPhone actually do?
Apple says the 48MP Fusion Main camera uses six laser-cut blades to move between f/1.48 and f/4. Wide open it gathers more light for dim scenes; stopped down it keeps more of a group in focus. It is real mechanical optics rather than a software depth effect, which is unusual on a phone.
Which one charges faster?
The Samsung, clearly. GSMArena measured 51% in 15 minutes, 84% in 30 minutes and a full charge in 43 minutes. Apple quotes about 50% in 15 minutes wired for the iPhone 18 Pro Max but does not publish a verified full-charge time, so we have not guessed at one.
