The Samsung Galaxy S25 Plus is a strange middle child. It's not just a bigger Galaxy S25, because it shares some technology with the Galaxy S25 Ultra. Sadly, not the best Ultra tech, like the 200MP camera sensor, the 5x zoom camera lens, or the titanium frame, let alone the S Pen. Still, the Galaxy S25 Plus isn't too hard to recommend.

The Qualcomm Snapdragon 8 Elite for Galaxy chipset is the same in every Samsung Galaxy S25 phone, and that's a significant upgrade no matter what older phone you're using right now. It's faster than last year's Snapdragon, and if your phone is a couple of years old or more, you're going to be in for a real treat.

The Galaxy S25 Plus also uses a higher-resolution display than the smaller Galaxy S25. With a nearly-4K resolution, Samsung has endowed the Galaxy S25 Plus and S25 Ultra with its new ProScaler technology. It says this tech is borrowed from the Samsung TV group, and it uses AI to upscale lower-resolution content to look better on a 4K screen.

I'll have to compare videos side by side to see if this makes a big difference, but Samsung seems to think it will be worth the upgrade from the standard S25 to the larger Plus model.

Because it's bigger, you also get a larger battery inside the Galaxy S25 Plus than in the Galaxy S25: 4,900mAh versus 4,000mAh. I know from my time testing other Snapdragon 8 Elite phones that this chipset can do a great job managing power and sipping battery juice, so hopeful the Galaxy S25 Plus will have winning battery life.

Otherwise, the new features on the Galaxy phones this year are all about Galaxy AI. All of the existing AI features are getting a little bit better. The photo editing is improved, and there are new AI assistant tools to help you with videos, whether you want to summarize them or cut them into GIFs.

The most interesting AI is yet to come. The Galaxy S25 Plus will include Samsung's Personal Data Engine, a secure hardware partition that will gather information about you for the AI to digest. It will read your messages, listen to your calls, see your photos, and mind your calendar.

The Galaxy S25 Plus can also use AI to talk to your Galaxy Ring and Galaxy Watch, and maybe even your Samsung TV and other SmartThings smart home devices. It will keep track of your habits, and look for patterns. Samsung suggested a few things the Galaxy AI might offer, like a better bed time schedule, but I have a feeling that it's waiting to see what sort of information and patterns its AI can put together.

That means the Galaxy S25 Plus, like the Galaxy S25, feels a bit unfinished. It feels like last year's phone with a new engine inside, which is fine, but not very exciting. The exciting Galaxy AI stuff will take a while to build, as the phone gathers more information about you. What will it do with all that info? It will store it securely, for one thing.

If you're worried about your phone learning so much about you, Samsung assures us that this personal data will be held securely on a hardware-locked partition protected by Samsung Knox. That's as good as Android protection gets, and it's so good that if you lose your Galaxy S25 Plus, you've lost the data stored in the Personal Data Engine. It doesn't exist in the cloud, and it can't be pulled off the device except during a Smart Switch to a new phone.

Great, I get a promise about what Samsung won't do with my personal data, but not a lot of detail about what it will do with all the data it harvests. Once my Galaxy S25 Plus really knows me, after a year or so of use, how will it be different? We don't exactly know, and the answer will probably change over time.

Thankfully, Samsung is giving the Galaxy S25 Plus a full seven years of Android and security updates, which means it will have plenty of room to grow. Whether it's worth buying now is a question of how much you want to invest in your own AI future.

Samsung Galaxy S25 Plus hands-on review: Price and availability

The Samsung Galaxy S25 Plus was unveiled at Galaxy Unpacked on January 22. It's available to pre-order now in two storage configurations: 256GB and 512GB. Every variant comes with 12GB RAM.

The phone will begin shipping on February 7 for the following prices:

Samsung Galaxy S25 Plus hands-on review: Specs

Here's a look at the Samsung Galaxy S25 Plus's key specs:

The Galaxy S25 Plus is a respectable phone for the price, though the Galaxy S25 Ultra hangs above its head with truly superlative specs. Every Galaxy S25 model gets the same Qualcomm Snapdragon 8 Elite chipset for Galaxy, which Samsung tells us Qualcomm has overclocked. Past 'for Galaxy' chips were overclocked 5% in the largest prime core, but we don't know what this year's improvement offers.

One big hardware surprise in the Galaxy S25 Plus is a Samsung ProScaler. Samsung says it’s borrowing technology from its renowned TV group to upscale video content on your Galaxy S25 Plus using AI. This isn’t motion smoothing; it won’t artificially boost the frame rate, just the resolution.

It doesn't seem like the smaller Galaxy S25 will get this feature – it may only come to the larger Galaxy S25 Plus and Galaxy S25 Ultra with QHD+ displays – and late rumors suggested that Samsung would make this a key selling point. I’ll have to take a look at video on the phones side by side to determine if the ProScaler makes a real difference.

Besides ProScaler, the Galaxy S25 Plus has a couple of other key advantages over the standard S25. If you want to use Samsung's SmartTags, you'll need the ultra-wideband (UWB) radio inside the Galaxy S25 Plus and Ultra.

The Galaxy S25 Plus should also charge faster than the Galaxy S25 when connected to a compatible Samsung Fast Charger 2.0 wall plug. We'll test the fastest charging capabilities of each Galaxy S25 model once we get them into our testing labs.

Samsung Galaxy S25 Plus hands-on review: design and display

The Galaxy S25 Plus doesn't just give you a bigger display; it gives you a better viewing experience, and this year there looks to be a larger gap between the Galaxy S25 and the Plus model than ever before, display-wise.

The Galaxy S25 Plus has the same resolution as the Galaxy S25 Ultra, at nearly 4K QHD+. At the highest resolution you can also use the new ProScaler hardware.

I can't find any ProScaler tech on Samsung's TVs, but I know Samsung's latest sets use AI to upscale lower-resolution content to 4K. Samsung says that all video that's played through the Galaxy S25 Plus (and the S25 Ultra) will get upscaled, but don't worry – this isn't motion smoothing. The frame rate isn't affected, just the resolution, so videos should look sharp but not unnatural.

Samsung Galaxy S25 Plus hands-on review: cameras

If you were hoping for better cameras in this year's Galaxy S25 Plus, your hopes will rest on the Galaxy AI and the Snapdragon 8 Elite chipset, because the camera specs have gone unchanged again. We haven't seen a big boost in cameras on the Galaxy S lineup, besides the Ultra, since the Galaxy S23.

Since then we've been stuck with the same 50MP main camera, 10MP zoom camera with 3x reach, and 12MP ultra-wide camera. The sensors haven't grown, and neither has the resolution, even though the Galaxy S25 Ultra got a 50MP ultra-wide sensor this year.

Samsung's Ultra phone has been at (or near) the top of our best camera phones list for two years, so Samsung clearly knows how to make a great camera, and it's confounding that only the Ultra gets the good stuff. It makes the other S25 phones feel like mid-range models compared to the Ultra, which is just silly. All of these phones are top-performers – it's only the cameras that are holding the two smaller phones back.

Maybe Samsung wasn't paying attention, but other phone makers have started to respect smaller phones by giving them better camera specs. The 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 got to try Samsung's new AI Assist tools, which work great for cutting up videos in addition to editing photos. You can basically tap on any video on-screen and create a GIF, or get an AI summary, or create a wallpaper from a still frame. That's in addition to all of the improvements in Samsung's AI photo editing in the Gallery app.

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 feel like afterthoughts for Samsung this year.

Samsung Galaxy S25 Plus hands-on review: performance and battery

The Snapdragon 8 Elite chipset is the genuine article, and the Galaxy S25 Plus continues Samsung's threepeat obtaining a slightly enhanced version of Qualcomm's top-tier chipset. The previous two Snapdragon for Galaxy chipsets boosted the main core's clock speed by 5%, but this year's benefits are still unclear. It's a negligible gain that primarily affects benchmark results, but someone has to claim the top spot, right?

Beyond the enhanced Snapdragon, this Galaxy includes more intriguing hardware than I expected. The Personal Data Engine is a dedicated hardware partition, managed by on-chip Samsung Knox security, a system powerful enough for many US federal agencies.

The information you let Galaxy AI gather remains on the device, and it can't be removed unless you switch to a new Galaxy phone. Transferring this personal data to a new phone is possible using Samsung Smart Switch. However, losing your phone means losing all that stored data. This is unfortunate, as some of Galaxy AI's future lies in its ability to adapt to your needs as it learns about you. It's fascinating to consider how the Galaxy S25 Plus might evolve with two, three, or even seven years' worth of personal data stored in its engine.

As for charging, Samsung hasn't embraced faster wired or wireless charging speeds. The Galaxy S25 Plus is limited to 45W, which is still a bit faster than the Galaxy S25, but the OnePlus 13 supports 80W, with a 100W adapter coming soon. Samsung needs to hurry up the charging times.

Samsung Galaxy S25 Plus hands-on review: software

The Galaxy S25 Plus will need to learn about you over time, with its most advanced Galaxy AI features awaiting your personal data. Again, this raises the question of what will the S25 do with this data. The specifics remain unclear, but the goal is to move beyond AI party tricks and create an 'agent', like a user interface, that learns your habits and preferences, and even makes new suggestions.

Galaxy AI will gather data not just from your phone, but also from your Galaxy Watch, Galaxy Ring, and SmartThings devices. Samsung suggests this could lead to personalized suggestions, such as optimizing your sleep environment or automating actions like turning off your TV when you fall asleep. This approach to AI feels potentially useful, a step beyond simple gimmicks; but like I said, it will need to gather a lot of data about you from a number of sources.

The Galaxy S25 Plus utilizes both Samsung Bixby and Google Gemini for various tasks, but Samsung wisely avoids emphasizing these names. The focus is on seamless functionality, though it's worth noting that many AI features were not yet working on the pre-production demo units I saw. I'm not sure exactly what will be working at launch, so I'll need to get hands-on with a final device to be sure.
