What Specs Do the U.S. Models Use?

- The S25 Ultra uses Snapdragon 8 Elite, tuned for Galaxy devices.
- The Pixel 9 Pro XL uses Google Tensor G4, built for AI tasks.
- Both support mmWave 5G in the U.S., so you get full carrier coverage with Verizon, AT&T, and T-Mobile.

Which Phone Performs Better Under Real Use?
Specs look great on paper, but numbers tell the real story. Benchmarks and heavy apps show how each phone handles stress.
In Geekbench tests, the Galaxy S25 Ultra scored higher in both single and multi-core. This shows its edge in raw CPU power.
However, in real tasks like video editing and photo export, the Pixel 9 Pro XL kept up thanks to its AI tuned Tensor G4. When I tried editing 4K clips, the Pixel used its smart processing to finish close to the Ultra.
For gaming, the Ultra held strong for longer sessions. The Tensor G4 warmed up quicker under stress, but the Galaxy handled games like Genshin Impact with more stable frame rates.

How Do Their Cameras Compare in 2025?
Photos are the deciding factor for many of us. Both phones take stunning shots, but in different ways.
- Galaxy S25 Ultra: 200 MP sensor, up to 10x optical zoom, best for detail and distance.
- Pixel 9 Pro XL: 50 MP sensor, powered by Google AI, best for color accuracy and instant processing.
When I tested them outdoors, the Ultra gave me sharper zoom shots. The Pixel gave me warmer tones and more natural skin colors.
At night, the Pixel’s AI gave brighter photos without much noise. The Ultra still performed well, but its photos looked sharper, almost too sharp for some tastes.
For video, the Ultra supported 8K capture. The Pixel stuck with 4K but used smart stabilization. Vlogging with both showed clear results, though the Pixel made video easier to handle on the go.

Which Lasts Longer? Battery & Charging Showdown
Battery life is often what decides your next phone. Both look close on paper, but actual tests show the differences.
The S25 Ultra has a 5000 mAh battery. The Pixel 9 Pro XL has 5060 mAh. Numbers are almost the same, so what matters is efficiency.
When I looped YouTube videos at 150 nits brightness, the Ultra lasted just over 17 hours. The Pixel lasted about 13 hours. That is a big gap for long trips.
Charging also matters. The Ultra supports up to 45W fast charging. The Pixel peaks at about 30W. Even with a 45W charger, the Pixel limits its charging speed.
Why does Google limit charging speed?
Google does not allow the same speeds across all models.
Even if a charger can deliver 45W, many Pixels only use 20W to 30W. Google sets these limits to control heat and protect battery health.
For anyone needing reliable charging, I suggest reading best Google Pixel fast charger in 2025. It shows which chargers work best with Pixel limits.
The Ultra also offers wireless charging and reverse wireless charging. This is handy when you want to top up earbuds. The Pixel offers wireless too, but slower than Samsung.
How Do Their Displays & Usability Compare?
Displays are where both phones shine. You will notice the difference in brightness and usability outdoors.
- Galaxy S25 Ultra: 6.9 inch AMOLED 2X, QHD+, 120Hz refresh, peak brightness near 3000 nits.
- Pixel 9 Pro XL: 6.8 inch OLED, QHD+, 120Hz refresh, peak brightness near 2400 nits.
When I used the Ultra outdoors, it stayed readable even under bright sunlight. The Pixel did well but looked a bit dim compared to the Ultra.
Touch response was fluid on both. The Ultra added S Pen support. I found the stylus handy for note taking and quick sketches. The Pixel does not support a stylus, so if you rely on handwriting, Samsung is the better choice.

Software, AI & Feature Differences — What Sets Them Apart?
Software is where these two phones stand apart. Samsung loads One UI. Google sticks with Pixel OS.
The S25 Ultra offers deep customization, split screen, and advanced multitasking. The Pixel focuses on clean design and smart AI tools.
Google gives you AI features like Magic Editor, Circle to Search, and Live Translate. When I tested Live Translate on a video call, it worked almost instantly. Samsung added Galaxy AI features, but Google’s AI still feels more polished.
Both promise 7 years of updates. This is a big deal in the U.S. because it matches the life span of most carrier contracts.
To see how Samsung balances software with performance, I recommend reading the Samsung Galaxy S25 Ultra review. It covers software tweaks in more detail.
What Does It Cost in the U.S, and Which Offers Better Value?
Price can be the deciding factor. Let us look at official U.S. pricing at launch.
- Galaxy S25 Ultra: $1,299 for the base 256GB model.
- Pixel 9 Pro XL: $1,099 for the base 128GB model.
The Pixel is cheaper, but you get less storage at the base level. The Ultra starts with more storage and offers S Pen support. U.S. carriers often bundle the Ultra with discounts if you trade in a recent Samsung phone. Google offers strong trade in deals through the Google Store.
For the Samsung, you can buy directly from the Samsung U.S. store or from Best Buy and Amazon. For the Pixel, the Google Play Store app also helps you manage updates and services.
