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).

Google races to put Gemini at the center of Android before Apple’s AI reboot

Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.

Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’

Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.

Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge

Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.

Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.

Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.

The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.

The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.

Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.

Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.

Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
