Google Pixel 10 Pro vs Samsung Galaxy S25 Ultra

The Google Pixel 10 Pro and the Samsung Galaxy S25 Ultra are two of the finest Android phones you can buy, and they cost almost the same. Yet they could hardly feel more different: the Pixel is a compact, AI-first phone that leans on Google's software smarts, while the Galaxy is a big, do-everything flagship with an S Pen and the most versatile camera system around. Here is how they compare, drawn from independent expert reviews of each, with current UK prices.

At a glance

The Google Pixel 10 Pro (around £713.99) is the compact clever one: a pocket-friendly 6.3-inch body, class-leading computational photography and the deepest Google AI, with seven years of updates. The Samsung Galaxy S25 Ultra (around £743.00) is the big all-rounder: a 6.9-inch screen, a built-in S Pen, a four-camera system and a larger 5000 mAh battery, also with seven years of support. They are priced within about £30 of each other, so this is about size, cameras and which extras you want.

Software and AI

Both run Android with seven years of OS and security updates, and both lean heavily on artificial intelligence. The Pixel 10 Pro runs Google's clean version of Android with the newest AI features baked in, from photo editing to on-device help. The Galaxy S25 Ultra runs Samsung's feature-rich One UI with its own Galaxy AI tools and the added trick of the S Pen stylus. If you want the purest software and the most cutting-edge Google AI, the Pixel leads; if you want a deeper toolbox and stylus input, the Galaxy is the more versatile of the two.

Design and build

This is the biggest practical difference. The Pixel 10 Pro is compact and light at around 207 g, built around a 6.3-inch screen that is easy to use one-handed. The Samsung Galaxy S25 Ultra is a much larger phone in a titanium frame, 8.2 mm thick and around 218 g, built around a 6.9-inch display and housing an S Pen in its body. Both carry IP68 dust and water resistance. If you want a phone that slips easily into a pocket, the Pixel wins comfortably; if you want the biggest screen and a built-in stylus, the Galaxy is unmatched here.

Screen

Both use superb OLED panels at 120 Hz. The Galaxy S25 Ultra's is larger at 6.9 inches and peaks at around 2600 nits, a big, immersive canvas that also works with the S Pen. The Pixel 10 Pro's 6.3-inch panel is smaller but actually a touch brighter, peaking at around 3000 nits, and it is far easier to handle. Both are gorgeous, high-refresh displays; the Galaxy gives you more screen and stylus support, the Pixel a brighter, more compact one that is still easy to read in bright sun.

Performance

The Galaxy has the raw-power edge. The Samsung Galaxy S25 Ultra runs the flagship Snapdragon 8 Elite, one of the fastest chips available, paired with 12 GB of RAM. The Pixel 10 Pro runs Google's own Tensor G5, which is tuned for AI and efficiency rather than outright speed and trails the top Qualcomm chips in benchmarks. In everyday use the Pixel feels quick and its AI features are a genuine draw, but for gaming and the most demanding tasks the Galaxy's Snapdragon chip is meaningfully more powerful.

Cameras

Both are among the best camera phones, with different philosophies. The Samsung Galaxy S25 Ultra brings hardware breadth: a 200 MP main sensor plus a four-camera system with two separate telephoto lenses for flexible long-range zoom. The Pixel 10 Pro counters with computational brilliance: a triple camera with a 5x optical telephoto, backed by Google's class-leading processing and AI editing that produces consistently excellent results with almost no effort. For sheer versatility and zoom reach the Galaxy's four cameras lead; for reliable point-and-shoot quality and clever AI tools the Pixel is superb. You will get outstanding photos from either.

Battery and charging

The Galaxy has the advantage on stamina and speed. The Samsung Galaxy S25 Ultra packs a 5000 mAh battery and charges at 45 W wired, so it lasts comfortably and refuels quickly. The Pixel 10 Pro carries a slightly smaller battery of around 4,870 mAh and charges more slowly, at roughly 30 W wired. Both will see out a full day, but the Galaxy's larger 5000 mAh cell and faster charging give it a modest but real edge for heavy users.

Price and verdict

At the time of writing the Pixel 10 Pro is around £713.99 and the Galaxy S25 Ultra around £743.00, so they are separated by only about £30 — price will not decide this.

Buy the Google Pixel 10 Pro if you want a compact, pocket-friendly phone with the cleanest software, the deepest Google AI and outstanding computational photography, all with seven years of updates. It is the easier phone to live with day to day.

Buy the Samsung Galaxy S25 Ultra if you want the big-screen, do-everything flagship: the S Pen, the most versatile four-camera system, the faster Snapdragon chip and the larger 5000 mAh battery. Both are excellent Android phones at almost the same price; you are really choosing between the Pixel's compact, AI-first simplicity and the Galaxy's size, stylus and sheer versatility.
