iPhone 17 Pro Max Specs vs. Galaxy S25 Ultra: Premium Phones Face Off
The battle of the biggest, baddest phones from Apple and Samsung.
Apple unveiled its new iPhone 17 lineup at its «awe dropping» event, and at the top of that list is, unsurprisingly, the iPhone 17 Pro Max. Now the most advanced iOS handset is going up against the top Android phones, and chief among them is the Samsung Galaxy S25 Ultra.
Both phones live up to their names, with nearly 7-inch screens, advanced cameras and the most powerful specs to date. While they have a lot in common, they follow slightly different approaches for assembling the most premium phone on the market.
Here’s how the iPhone 17 Pro Max specs match up to the Samsung Galaxy S25 Ultra.

iPhone 17 Pro Max vs. Samsung Galaxy S25 Ultra price comparison
- iPhone 17 Pro Max (256GB of storage): $1,199
- Samsung Galaxy S25 Ultra (256GB of storage): $1,299
The iPhone 17 Pro Max is $100 cheaper than the Galaxy S25 Ultra, which has been the same price gap between these phones in prior years. Samsung’s phone does have a notable hardware extra in its S Pen stylus (stored within the handset), but it’s also far more likely to go on sale than Apple’s big handset, assuming prior years’ trends continue.
iPhone 17 Pro Max vs. Samsung Galaxy S25 Ultra design and displays
- iPhone 17 Pro Max: Heat-dispersing focus — this year’s Pro Max reverts to an aluminum frame and introduces a vapor chamber to better vent heat.
- Samsung Galaxy S25 Ultra: Best screen yet — the display’s new anti-reflective coating on the Ultra may be its best feature.
These are the biggest and densest phones beyond foldables, so they stack up pretty comparably, at least on the outside.
The iPhone 17 Pro Max has a 6.9-inch OLED display, while the Galaxy S25 Ultra has a 6.8-inch screen (both have 1-120Hz variable refresh rates) — and back in January when the latter was released, CNET Managing Editor Patrick Holland called «the best I’ve seen» on a phone thanks to its new anti-reflective coating that makes the phone more usable under direct light along with 2,600-nit top brightness. For its part, the iPhone 17 Pro Max is easier to see in daylight with its 3,000-nit maximum brightness (up from 2,000 nits in last year’s iPhones).
Samsung’s phone is slightly lighter at 218 grams thanks to its titanium frame, which is potentially more durable than the aluminum frame on Apple’s premium phone (which is heavier at 233 grams).
But interestingly enough, it seems Apple reverted from the titanium frame on the iPhone 16 Pro Max back to aluminum in its new top-tier phone in favor of better thermal regulation. To handle heat even better, the iPhone 17 Pro Max has a vapor chamber filled with deionized water sitting over the CPU and other chips to disperse heat away from the silicon. The S25 Ultra has its own vapor chamber (40% larger than its predecessor’s, Samsung said).
The S25 Ultra also has the advantage of its own stylus that tucks into a dedicated slot on the underside of the phone — but unfortunately, it’s not as smart as the S Pen of previous S-series Ultra models. Samsung took out the remote Bluetooth controls, which the company said were only used by barely 1% of Ultra owners, but it’s still disappointing to see tech revert.
Like all iPhones since last year’s models, the iPhone 17 Pro Max does have a Camera Control button on its right side that’s explicitly used to launch the Camera app, take photos and tweak settings while shooting. The button can also be used to activate Visual Intelligence which let’s you do a Google image search or prompt for ChatGPT using what the camera is pointed at.
Comparing iPhone 17 Pro Max and Samsung Galaxy S25 Ultra cameras
- iPhone 17 Pro Max: Nearly all cameras now sharper — everything but the main camera got a megapixel upgrade.
- Samsung Galaxy S25 Ultra: Better ultrawide camera — the 50-megapixel ultrawide captures more light and detail.
From the outside, not much looks different with either phone’s array of cameras compared to their predecessors, though the iPhone 17 Pro Max’s rear camera bump has been extended across the width of the phone. But the big changes are packed inside that «plateau,» as Apple calls it, with improvements to nearly all of its cameras.
The iPhone 17 Pro Max’s 48-megapixel main and ultrawide cameras are largely untouched, but the telephoto camera is now also 48 megapixels (up from 12 megapixels in last year’s Pro Max). All three are «dual fusion» cameras that can zoom in twice at 12-megapixel resolution using sensor cropping; this effectively means the telephoto can go to the equivalent of 8x optical zoom, or up to 40x digital (up from 25x).
The big upgrade for selfie lovers: the front-facing camera is now 18 megapixels (up from 12 megapixels in last year’s model), which is nice but less important than the larger sensor behind the lens. It’s square in shape, which allows users to switch between taking selfies in either horizontal or vertical orientation without rotating their phone. It also enables Center Stage, the video chat feature that first debuted on iPad Pro and Mac devices that keeps the focus on the user even if they move around and can adjust the orientation if more people enter the frame.
The Galaxy S25 Ultra retains its four rear camera setup, fronted by an impressive 200-megapixel main shooter. But it’s the 50-megapixel ultrawide camera (up from 12 megapixels in the S24 Ultra) that delighted CNET reviewer Holland, who felt the larger sensor afforded crisper shots with more light in both very wide and close-up macro shots. The phone also has a 10-megapixel 3x optical zoom paired with a 50-megapixel 5x optical zoom for different levels of telephoto shots, topping out at 100x «Space Zoom.»
Both phones have dueling AI-assisted tools for video. The iPhone 17 Pro Max has the Audio Mix feature introduced in its predecessor that isolates desired audio sources — like subjects talking — and cancels other ambient noise. The Galaxy S25 Ultra has its own tool, Audio Eraser, which trims away wind, music, street noise or other disturbances. As a last difference, the Galaxy S25 Ultra can shoot footage in 8K while the iPhone 17 Pro Max tops out at 4K video.
iPhone 17 Pro Max vs. Samsung Galaxy S25 Ultra specs compared
- iPhone 17 Pro Max: Better specs, bigger battery — the Pro Max gets a new chip, better performance and longer battery life.
- Samsung Galaxy S25 Ultra: Great performance — the S25 Ultra boasts better performance than any other phone we’d tested.
Both phones exist at the absolute top of their lineups, and are both in the running for the most powerful phone on the market anywhere in the world. Unsurprisingly, they’re pretty competitive with each other in terms of specs and performance, with each edging out the other in specific ways.
The iPhone 17 Pro Max packs a new A19 Pro chip that, combined with the improved heat management, results in 40% better sustained performance compared to last year’s Pro Max, Apple said during the new phone’s launch presentation. Apple has continued not to state how much RAM the phone packs (conventional wisdom suggests at least 8GB to run AI features).
The iPhone 17 Pro Max comes with configuration tiers for 256GB, 512GB, 1TB and the new 2TB option. That max storage does push the iPhone 17 Pro Max’s overall price to around $2,000. Apple also doesn’t release exact battery capacity, but did suggest the Pro Max has an even bigger one this year. In CNET’s battery tests the iPhone 17 Pro Max scored better than any phone we’ve tested, including the Galaxy S25 Ultra.The iPhone 17 Pro Max has a top wired charging speed of 40 watts or wireless at 30 watts, along with built-in MagSafe magnetic attachment capability.
The Samsung Galaxy S25 Ultra packs a Samsung-customized Snapdragon 8 Elite chip and 12GB of RAM, both of which enable more on-device AI that runs smoother than the hybrid and cloud AI tools used in prior Galaxy Ultra models. In benchmark tests, the Galaxy S25 Ultra outperformed other leading smartphones, including the OnePlus 13 and last year’s iPhone 16 Pro, but we’ll have to wait for our tests on the iPhone 17 Pro Max to truly compare both. Samsung’s premium phone has 256GB, 512GB and 1TB storage options.
The Galaxy S25 Ultra has a 5,000mAh battery, 45-watt maximum wired charging and Qi2 wireless charging up to 15 watts, though it doesn’t support magnetic attachments (unless you get a case with built-in magnets).
Of course, both phones have their own suites of generative AI technology. Apple quietly didn’t introduce any new features this year, relying on the Apple Intelligence suite of assistive tech that debuted with last year’s iPhone 16 series. Samsung’s phone has its own suite of Galaxy AI features, like answering requests with info from apps and Google’s Circle to Search feature that can now recognize audio in videos and social media posts (or even tunes you hum yourself, supposedly).

Aurora Borealis Alert: 21 States Could Marvel at the Dazzling Northern Lights Tonight
A strong G3 magnetic storm is pushing the aurora further south than it’s been since June 2025.
Remember that dazzling night in May 2024, when the aurora borealis lit up states that almost never see its colorful glow? Some of us have been chasing that natural marvel ever since.
Now, the sun is at its solar maximum, and many might get their chance to see the northern lights again. Late Thursday night and early Friday morning, a moderately powerful magnetic storm impacts the Earth’s magnetic field, making the aurora visible in 21 states.
Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.
According to NOAA, the aurora will be visible in Idaho, Maine, Michigan, Minnesota, Montana, North Dakota, South Dakota, Washington and Wisconsin. Those with a high enough vantage point facing north should also be able to see it in Illinois, Indiana, Iowa, Nebraska, New Hampshire, New York, Ohio, Oregon, Pennsylvania, Wyoming and Vermont. Alaskans and Canadians will have the best view.
This is only a prediction. The aurora could be stronger or weaker depending on how things go. If you’re just south of any of these states, it may be worth seeing if the aurora makes it down to you.
This storm is a continuation of one that hit the US on Wednesday night, for which NOAA initially predicted a G2 magnetic storm but ultimately classified it as a stronger G3 storm.
Both storms come from a pair of X-Class coronal mass ejections, or eruptions of solar material and magnetic field that the sun launched toward the Earth on Nov. 4. X-class is the highest designation, so these ejections were pretty big.
Tips for viewing the northern lights
The methods for viewing an aurora are straightforward.
You’ll want to get as far away from the city and suburbs as you can to minimize light pollution. After that, you’ll want to get as high up as possible and then face north.
The northern states in the US will have the best view, but those further south in the prediction zone may still see something if they’re high enough and it’s dark enough outside.
Avoiding light pollution may be tough because the moon is almost full. It may drown out the aurora along the southern reaches of NOAA’s prediction area.
If you do decide to head out, you also have a pretty good chance at spotting a shooting star since there are four meteor showers active right now, including Orionids, Leonids, Northern Taurids and Southern Taurids. Three of the meteor showers are scheduled to peak in November.

NASA’s Escapade Mission May Finally Reveal How the Martian Atmosphere Works
NASA, Blue Origin and UC Berkeley combined efforts for NASA’s lowest-cost mission to Mars.
Sending anything to Mars is a much more difficult process than it seems. In the 1960s, the Soviet Union tried (and failed) in its first nine consecutive attempts, and the US was only able to succeed in quick flybys. The losing streak came to an end in 1971 with the success of the Mariner 9, the first spacecraft to orbit another planet.
More than 50 years later, Mars is still tough to get to, with only seven functional orbiters and two on-surface rovers still operating, most of which are run by NASA.
On Sunday, NASA’s Escapade, a collaborative effort among the space agency, UC Berkeley and Jeff Bezos’ Blue Origin, will launch and attempt to add two more orbiters to the elusive club of successful missions to Mars. Liftoff is scheduled for 2:45 p.m. ET.
The mission is simple on paper: Blue Origin’s New Glenn rocket will launch two Escapade orbiters into space on Nov. 9, depending on the weather and other factors.
Once there, the orbiters — nicknamed Blue and Gold after UC Berkeley’s school colors — will separate. This is where things get a little complicated. Blue and Gold will hang out at the L2 Earth-Sun Lagrange point, a part of space behind the Earth when viewed from the sun, where the orbiters can quite literally hang out without getting lost in space. They’ll stay there for a year before doing a quick flyby of Earth and departing for Mars. The twin orbiters are expected to arrive at the Red Planet by November 2027.

Space agencies launch missions all the time but few of them have the subtext of Escapade, which has not one but three underlying storylines to pay attention to.
New Glenn’s official debut
NASA has tapped Blue Origin’s large New Glenn rocket for the launch. New Glenn is the proverbial new kid on the block, and the Escapade mission will be the company’s first official mission into space. The rocket’s role will be to launch Escapade into orbit and then return to Earth.
Blue Origin sent New Glenn into orbit for the first time in January 2025. That mission, dubbed NG-1 by Blue Origin, showed that the rocket could launch and make it to space while demonstrating the company’s Blue Ring orbital transfer vehicle. Things didn’t exactly go as planned, however. Upon reentry, New Glenn’s first stage was unable to stick its landing, missing its target and plunging into the Atlantic Ocean, prompting an FAA investigation.
For the Escapade mission, all eyes will be on whether Blue Origin will do better this time in the landing phase. Not only is this the first NASA mission for the space company, owned by the CEO of online retail giant Amazon, but it will also make its second attempt to land New Glenn’s first-stage rockets without incident.
Should the company succeed, Blue Origin will join Elon Musk’s SpaceX as the only commercial vendors with reusable space launch vehicles. This could help reduce the cost and increase the frequency of space launches.
The 13 lives of Escapade
One of the challenges of the Escapade mission is its budget. Missions to Mars are usually expensive. The Mars Exploration Rover mission started in 2003 and launched a year later cost a hair over $1 billion, with $744 million of it going to vehicle design and launch. Even less expensive initiatives, like the failed 1999 Mars Polar Lander, still cost well north of $100 million.
Escapade didn’t have that budget. It’s part of NASA’s Small Innovative Missions for Planetary Exploration program. Its budget was less than $80 million, and to build the two orbiters, UC Berkeley and Rocket Lab were allocated $55 million of that total.
«Building two interplanetary spacecraft for $55 million was never going to be simple,» Dr. Robert Lillis, associate director for Planetary Science at UC Berkeley and the Escapade mission, tells CNET. «They say ‘space is hard’ and they’re right. For us and our spacecraft partners at Rocket Lab, it was tough to build robust, well-instrumented interplanetary probes on a low budget, so challenges were many.»
Researchers at Berkeley began work on Blue and Gold in 2016, and over the years, they dealt with myriad roadblocks, including budgetary concerns, the COVID-19 pandemic, supply issues from suppliers and even personal illnesses.
«I’ll put it this way, we have a slide deck called ‘The Nine Lives of Escapade’ and I think we’re up to 13 now,» Lillis says. «I could write a book on all the things that could’ve doomed the mission.»
The cost of admission
In 2013, the Indian Space Research Organization launched its Mars Orbital Mission, a successful attempt to put a satellite on the Red Planet. The total cost of the mission was $74 million, which undercut all other missions to Mars by a fairly significant margin when adjusting for inflation.
Escapade’s budget is roughly the same, with NASA paying Blue Origin $20 million for use of the New Glenn rocket in addition to the $55 million given to UC Berkeley and Rocket Lab for the creation of the two orbiters. Should the mission be a success, it’ll be NASA’s first low-cost mission to go as far as Mars, and the second such mission to succeed.
Reducing the cost of admission is an important milestone for NASA. It would open up more opportunities for future Mars missions, which could help pave the way for human exploration someday, although there are many other milestones that need to be hit before that can happen.
UC Berkeley and Rocket Lab successfully developed two orbiters that will spend their lifetimes scanning Mars’ magnetic field to gain a deeper understanding of its history, all while operating within a budget that may make future missions to Mars more frequent and affordable.
The Martian magnetosphere
Despite being one of Earth’s closest neighbors, there are still a lot of question marks surrounding Mars. It’s pretty well established that the planet had water at some point. Over the span of its history, the Martian magnetosphere started getting stripped away by solar winds, making it nearly impossible for water to continue to exist.
Science has a limited set of data that comes from single orbiters over the span of decades and Escapade hopes to fix that by having two orbiters that follow each other so that researchers can get more consistent measurements of the Martian magnetosphere. As Lillis says, the magnetosphere on Mars changes by the minute, so waiting for a single orbiter to circle back around leaves a lot of those changes unmeasured.
«With a single orbiter, we could measure conditions in the upstream solar wind, but then have to wait a couple of hours before the spacecraft orbit brought us into the upper atmosphere to measure the rates of atmospheric escape,» Lillis said. «That’s too long: We know the space weather propagates through the system in only one or two minutes.»
The ultimate purpose of the mission is to measure and observe how solar weather interacts with the Martian magnetosphere. Per Lillis, solar winds have been eroding the magnetosphere on Mars, similar to how water erodes rock in a river. Escapade will help science determine how fast and how much of the magnetosphere has eroded under the sun’s constant onslaught.
Because space weather can be so unpredictable and the existing data is spread out too far in terms of time, researchers aren’t quite sure what they’re going to find when they get there. Berkeley has simulation models that can predict things over the span of hours. Lillis says that the data from Escapade’s two-orbiter setup will help fill in a lot of those gaps.
«With Escapade, we can measure cause and effect at the same time, i.e., the solar wind and upper atmosphere simultaneously,» says Lillis. «To start to understand this highly dynamic system, we need that cause and effect perspective.»
You can watch the livestream of the Escapade mission launch on Sunday, at Blue Origin’s website.
