The Samsung Galaxy S25 was left home alone this year. In all the excitement over Galaxy AI, the redesigned Galaxy S25 Ultra, and ProScaler on the bigger phones, I think Samsung forgot something important: it forgot to bring the Galaxy S25 into 2025.
The Galaxy S25 looks a lot like last year’s Galaxy S24, and the Galaxy S23 from the year before that. It’s a bit thinner and a tad lighter, but not much else has changed.
It uses the same cameras as the Galaxy S23. This year’s model comes with 12GB of RAM instead of 8GB, but it still starts at 128GB of storage, a paltry gallery space for all the AI images you’ll create, surely.
The battery hasn’t grown more than 3% larger over the past two years, though I surmise based on my time testing other Qualcomm Snapdragon 8 Elite phones (like the OnePlus 13) that the Elite chipset inside this phone should prove a boon for battery life. Still, we couldn’t have had a bigger cell? Or faster charging? Nope. Same, same.
Why not just sell the Galaxy S23 with a newer processor inside and call it a day? Shhhhh, I think that’s pretty much what Samsung has done.
I jest, and hopefully we’ll see a bigger refresh next year, but this year is all about the software inside, and the AI that is totally, assuredly coming soon.
I don’t mean the improved photo-editing tools, or the audio eraser AI for videos, or the better Bixby that can find settings using natural language questions. I’m talking about next-generation AI agents, so-called agentic AI.
The Galaxy S25 is going to gather information about you from everywhere. It will use your phone, your Galaxy Ring, your Galaxy Watch, and even your smart home devices, like your lights and your TV. It will learn about you, and keep everything it learns in a secure lockbox on your phone.
It will gather that info so that it can… um, actually I’m not sure. Samsung suggested it might turn off the TV when you fall asleep, or suggest better lighting for bed time, but most of what we heard so far is promises of what’s to come. Not quite a preview, just a hint.
Look at how Samsung talks about this phone. In its official press release, Samsung MX Business President TM Roh says the Galaxy S25 “opens the door to an AI-integrated OS…” and the release says “It’s the starting point of a shared vision with Google…” This isn’t a finished product. It’s a start, an empty vessel, and you fill it with data about you.
I like the future that Samsung is building towards. It clearly understands that AI needs to make your phone easier to use and more accessible, and I think the best improvements we’ll see in the Galaxy S25 will be Bixby’s ability to help parse Samsung’s wealth of features.
I like that Samsung is taking personal data so seriously with its Personal Data Engine. I’m very curious about what Samsung and my Galaxy S25 will do with all of my personal data, and if Galaxy AI will truly improve as it learns more about me and my habits. There’s a lot of potential, but Samsung has only demonstrated a patchwork of possibilities, not a coherent whole.
I suspect this is a phone with a long, growing tail, so we’ll have to review this phone and revisit it as Samsung keeps improving and evolving Galaxy AI.

Samsung Galaxy S25 hands-on review: design and display
I’m spending so much time talking about AI developments on the Samsung Galaxy S25 because otherwise this generation of Galaxy S is confoundingly unchanged from last year, and the year before. Except for the Galaxy S25 Ultra, which now simply looks like an even bigger version of the Galaxy S25 Plus, the basic design will be recognizable, and a bit tired.
I don’t fault Samsung for not making huge changes this year. There are expensive new components inside, so a massive redesign would have driven the price higher. Samsung has laudably managed to keep the price stable with last year’s Galaxy S24 launch, which is a feat in itself, considering the rumors I’ve heard about sky-high prices for Qualcomm’s coveted Snapdragon 8 Elite chips.
More on those later; first the Galaxy S25’s design. To borrow a car analogy, the Galaxy S25 is like the Toyota Camry of the smartphone world, versus Apple’s Honda Accord. In other words, these phones look the same every year, and if you squint they kind of look like each other.
We’re long past the point of expecting a new look every year. We get minor changes, some flourishes and improvements, but most of the improvements happen under the hood.
Samsung Galaxy S25 hands-on review: cameras
Nothing to see here so far, at least on paper. I suspect we’ll see actual improvements once we’ve had time to test the new Galaxy S24 cameras, thanks to the Snapdragon 8 Elite chipset, which includes a new image processing pathway that has shown great results on competing Snapdragon phones.
The specs seem to be exactly the same as we’ve seen on Galaxy S phones for the last two years, at least the not-Ultra models. While the Ultra this year got a new 50MP camera to replace its old 12MP ultra-wide, the Galaxy S24 and Galaxy S24 Plus both retain the same 50MP main camera, 10MP 3x zoom, and 12MP ultra-wide lens.
Maybe Samsung wasn’t paying attention, but phone makers have started to respect smaller phones by giving them better camera specs. The Apple iPhone 16 Pro and Google Pixel 9 Pro offer a smaller, less expensive option than the Pro Max and Pro XL models, without sacrificing megapixels or zoom.

I wish we got the same on a smaller or less expensive Galaxy S25, but instead we get the mighty Ultra, and then the rest. Instead, Samsung has focused on improving photos through AI, both before and after you take the shot.
I got to try Samsung’s improved photo-editing tools with generative AI, and they were very impressive. When the Gallery app removed someone from a photo, the wood floor beneath their feet was left unbroken, with clean wood plank lines.
Still, software seems like a poor substitute for better glass and more advanced sensors. With the cameras and in too many other ways, the Galaxy S25 and Galaxy S25 Plus seem like afterthoughts for Samsung this year.
Samsung Galaxy S25 hands-on review: performance and battery
The Snapdragon 8 Elite chipset is the real deal, and the Galaxy S25 continues Samsung’s three-year tradition of getting a slightly overclocked version of Qualcomm’s best chip. We’re not sure exactly what that means, but the last two ‘Snapdragon for Galaxy’ chipsets overclocked the big primary core by 5%. It’s a minimal advantage that only matters in benchmarks, but somebody has to be #1, right? So Samsung gets the bragging rights.
Besides the overclocked Snapdragon for Galaxy, there’s more interesting hardware in this Galaxy than I expected to find. The Personal Data Engine is an actual hardware partition, governed by the on-chip Samsung Knox security that is good enough for most three-letter US Government agencies. The info that you feed your Galaxy AI will stay on the phone, keeping your data secure.
If you get a new phone, you can use Samsung Smart Switch to transfer that personal data, but if you lose your phone, all of the data you stored will be lost.
That’s kind of sad, because the promise of AI will be how much it can adapt to your needs as it gets to know you. I wonder if the Galaxy S25 will seem like a whole different animal once it has two, three, or even seven years of my personal data stored within its engine.
For charging, Samsung hasn’t stepped into the modern age with faster wired or wireless charging, and the Galaxy S25 is stuck at around 45W while the OnePlus 13 can push 80W, with a 100W adapter on the way. The difference means missing out because you were waiting for your phone to wake up.
Samsung Galaxy S25 hands-on review: software
The Galaxy S25 is a phone that will get to know you… eventually. Samsung’s new flagship phone could be one of the best phones of 2025, but it’s hard to get too excited about it… yet. That’s because Samsung is handing us tabla rasa, a blank slate, waiting to be filled with our personal data.
If asking your smartphone to learn everything – from your sleep habits to your photo gallery to your entire messaging history – sounds frightening, Samsung is well aware of that, which is why the most interesting part of the Galaxy S25 is the so-called ‘personal data engine,’ a secure container for all of the personal data that the Galaxy S25 gathers about you.
What will it do with all of that information? It’s hard to say, because we haven’t gotten that far. If the last generation of AI features seemed like party tricks, the next generation is going to work hard to get to know you, and then… yada yada, we’ve got AI!
Galaxy AI will gather information from more than just your phone. It will get info from your Galaxy Watch and Galaxy Ring, and it will compare that with data collected from your Samsung SmartThings smart-home devices.

Samsung says, for example, that Galaxy AI might notice if you fall asleep better with certain lights turned on or off, and make suggestions. Your Galaxy Ring will notice that you’re asleep, and it will tell your phone to tell your Samsung TV to shut down.
We’re still learning about everything that Galaxy AI might do, but this feels like the next step for mobile AI. This isn’t sleight-of-hand; it feels useful.
The Galaxy S25 uses Bixby to control Galaxy apps and smartphone settings, and Google’s Gemini for things like generating text in Messages, and Circle to Search, but Samsung is wisely keeping the names to itself. Users don’t need to know if they’re engaging with Bixby or Gemini or Galaxy AI; it will just work, at least according to Samsung.
Unfortunately it doesn’t just work just yet, at least not in my brief hands-on time with the Galaxy S25. Many of the new AI features were not working on the pre-production demo units I got to try. Samsung reps had phones with more features, but I don’t think everything will be ready at launch.
Most of it will need a lot more data from you and me, after all.
