Samsung Galaxy S26 vs S25: Powerful flagships compared

TL; DR

​​✨​ The Samsung Galaxy S26 lineup improves upon its predecessor in meaningful ways across the board, with more powerful AI integration, faster charging, and an upgraded chip for all 3 models. Whether the upgrade is worth it or not, though, depends on the model you’re considering. The S26 Ultra is the model that’s seen the most improvement, with new features like the Privacy Display and incredible camera setup being the most notable changes.

• If you’​​re considering upgrading from the S25 or S25+ to the S26 Ultra, this may be worth the jump. The S26 and S26+, however, don’t see as many differences from their counterparts in the S25 lineup.

• If you’re upgrading from an older S series phone, the S26 line will be a marked improvement.

• If you already have an S25, though, you may want to wait a little longer to upgrade.

Which base model is better: the S26 or S25?

The S26 performs slightly better than the S25, but the difference may not be super noticeable to most people. If you're deciding between the Samsung Galaxy S26 and the Galaxy S25, it's important to look beyond the launch hype and compare what actually changed. Both phones share a similar design and many of the same core specs, but Samsung has introduced a few updates to performance, AI features, and battery efficiency with the S26.

In this comparison, we break down the differences between the two base models, from hardware specifications and camera capabilities to AI-powered features and overall performance. We'll also look at whether the upgrades in the S26 are significant enough to justify the higher launch price, especially if you already own the S25.

S26 and S25 base model specs compared

​While the Galaxy S26 and Galaxy S25 share nearly identical hardware, the S26 introduces a newer chip, slightly larger battery, and expanded AI capabilities that provide modest performance improvements over the previous generation.

S26 vs S25 pros and cons

​​✨ Overall, the Galaxy S26 offers slightly better performance, battery life, and more advanced AI features, but since the camera hardware and memory remain the same, the improvements over the Galaxy S25 are fairly incremental, making the older model a better value for many users.

S26 vs S25: Features and benefits compared

✨The S26 sees few upgrades to the S25’s hardware, but the enhanced AI features and faster chip allow for performance improvements, nonetheless. With the price difference considered, though, these are only incremental improvements.

The S25 base model was already at the top of its class and successfully competed with its competitor’s counterpart, the iPhone 16. With its Galaxy AI integration, impressively long battery life, and multiple storage options, it’s a powerful flagship phone. Its 6.2-inch Dynamic AMOLED 2X display has a 120Hz refresh rate for smooth graphics and switching between apps, and the Snapdragon 8 Elite for Galaxy already packed a fast performance punch. The camera hardware leaves something to be desired though; while photos in good lighting may turn out crisp, the camera’s low-light performance is lacking. The slim aluminium design is lightweight and durable.

The Samsung Galaxy S26 takes much of the same hardware as the S25 without any upgrades. It features the exact same display and camera setup as the S25, but its enhanced AI features and upgraded Exynos 2600 (2nm), 10-core for Galaxy chip make the phone’s performance slightly better. Perhaps the biggest noticeable change here is with photos; although the camera hardware is the same, AI-powered on-device editing tools can help you remove noise from photos and videos, making the images a little clearer than on the S25. It’s worth noting that in a press release, Samsung noted that the S26 phones have an “industry-leading camera system”, but this only seems to be true for the Ultra.

The S26 also gets a slightly bigger battery, allowing for a longer battery life than the S25, but with the same charging speed. Samsung has also eliminated the 128GB storage option for the S26, so you only have 2 options to choose from, which is likely the reason behind the S26’s higher launch price.

Samsung Galaxy S26+ vs S25+: Which performs better?

The Samsung Galaxy S26+ performs slightly better than the Galaxy S25+. The two phones share many of the same core features, including their large 6.7-inch display, similar camera systems, and premium build. However, the S26+ introduces several updates under the hood, including a newer Snapdragon chip, improved Galaxy AI capabilities, and slightly faster wireless charging.

In this comparison, we’ll take a closer look at how the two Plus models differ in terms of performance, battery efficiency, AI-powered features, and overall value to determine whether the S26+ is a meaningful upgrade over the S25+.

S26+ and S25+ specs compared

✨ While the Galaxy S26+ keeps much of the same hardware as the S25+, its faster chip, improved AI features, and slightly better wireless charging provide modest performance and usability gains, but the core experience remains very similar.

S26+ vs S25+ pros and cons

✨The S26+ takes the exact same hardware as the S25+ and improves upon certain aspects thanks only to its updated chipset and more capable AI features. Here, however, the price increase is even less justified as the exact same storage options are offered for each phone.

S26+ vs S25+: Features and benefits compared

The S25+ is a significant step up from the S25 base model display-wise, with a higher screen resolution (3120 x 1440 pixels) and a larger display overall. The S25+ also gets a much faster wired charging speed than its base model at 45W, but the wireless charging speed of 15W leaves something to be desired. You also see an extra hour of battery life thanks to its larger battery. The display and the battery are the only significant differences between the S25+ and the regular S25, though, as the camera capabilities, build, chipset, and AI features remain the same.

The relationship between the S26+ and the S25+ is honestly quite similar to that between the S26 and S25 base models. There are some incremental improvements, but nothing revolutionary. The battery of the S26+, while the same size as the S25+’s, offers one extra hour of use and the same wired charging speed. The wireless speed, however, gets a bump from 15W to 20W. Similar to the base models, the major changes here are the improved AI capabilities and the faster chip.

And when it comes to the S25+ and S26+, Reddit users are calling out the seemingly unnecessary price jump:

“It's still a good phone, just not anything new. And at least where I live, it’s has become more expensive even though there is actually nothing new of value.”

Samsung Galaxy S26 Ultra vs S25 Ultra: How much better is the S26 Ultra?

The Galaxy S26 Ultra represents the most significant upgrade in the S26 lineup when compared to its predecessor, the Galaxy S25 Ultra. While both devices share a similar display size and camera layout, Samsung has introduced several notable improvements, including faster charging, enhanced AI-powered camera tools, and a new Privacy Display feature.

Below, we compare the two Ultra models across their specifications, performance capabilities, camera systems, and overall design to see whether the S26 Ultra’s upgrades justify the higher price.

Galaxy S26 Ultra and S25 Ultra specs compared

✨ The Galaxy S26 Ultra upgrades nearly every aspect of the S25 Ultra, from AI-assisted photography to faster charging and the new Privacy Display, making it the most worthwhile S26 series upgrade for enthusiasts seeking top-tier performance, especially for the same launch price as its predecessor.

S26 Ultra vs S25 Ultra pros and cons

✨ Overall, the S26 Ultra delivers meaningful enhancements in camera quality, AI features, and charging speed, but the downgrade from titanium to aluminium and the higher price may make it less appealing to users who prioritise durability or value.

S26 Ultra vs S25 Ultra: Features and benefits compared

✨If you're thinking about upgrading to the S26 series from the S25, the jump would be most worth it for the S26 Ultra with its improved camera, Privacy Display, faster charging, and 16GB of RAM.

The S25 Ultra is quite obviously the phone in the S25 lineup with the best features and performance. Its quad-camera setup produces much higher-resolution photos than its counterparts, and its 1TB storage option allows you to store all this media with no problem. Coming with the biggest display in the S25 lineup, gaming and switching between apps is crisp, fast, and clear with a 120Hz screen refresh rate. Its features are supported by powerful AI capabilities, and its built-in S Pen supports productivity. All these features and more are wrapped in durable titanium, providing a premium look and extra protection against bumps and scratches.

The S26 Ultra not only improves upon almost every single feature of the S25 Ultra, but it also adds some exciting new bells and whistles that tech enthusiasts will appreciate. The battery supports much faster wired charging, capable of reaching 75% in just half an hour. The quad-camera setup is improved with an even lower f-stop for the main rear lens, providing even clearer photo and video capabilities in low-light conditions. The AI-powered Photo Assist features also add new editing options to make your photos even better. It offers all the same storage options as the S25 Ultra, but it comes with a RAM upgrade to 16GB for the 1TB option. With this upgraded memory, the new Snapdragon for Galaxy chip, and improved AI integration, this is Samsung’s fastest S series smartphone yet.

The S26 Ultra also adds a feature many users are excited about: Privacy Display. The Privacy Display setting prevents anyone standing beside, in front of, or behind you from seeing your screen, keeping your passwords and photos private. This setting can be turned on and off, and you can also use specific settings for certain apps.

The only potential drawbacks of the S26 Ultra are the higher launch price and the build. That’s right: the 26 Ultra has been downgraded from a titanium build to an aluminium one, meaning slightly less durability than the 25 Ultra.

Shopping tips

✨If you’re willing to wait a little while, shopping refurbished on Back Market will be the best way to get an S26 phone at a lower price.

Final thoughts: The S26 may not be worth the upgrade

The new S26 series largely takes the features of the S25 series and marginally improves upon them, especially for the base and Plus models. The main differences between the S25 and S26 (and the S25+ and S26+) are the new chipset and improved AI features, making the price jump for the S26 seem like a little much, especially if the new AI features will eventually come to the S25 line via software updates. We could, however, see how you may justify jumping from an S25 model or an older phone to the S26 Ultra considering its amazing camera setup, introduction of Privacy Display, and much faster charging capabilities.

If you’re on a budget and don’t care much about AI features, we’d recommend either upgrading to an S25 model if you’re coming from an older phone like an S24 or sticking to your current S25. If you’rereally interested in testing out the new AI features though and you need the Privacy Display, consider making the leap to the S26 Ultra. Ultimately, it comes down to your priorities.
