Samsung Galaxy S26 vs. Galaxy S25: What’s changed and which one should you buy?

Following Samsung’s Unpacked event, the Samsung Galaxy S26 is available for pre-order, and it looks very familiar. That is not necessarily a bad thing. Like recent updates in the Galaxy S line, Samsung is refining its flagship rather than dramatically reinventing it.

Both phones share a lot of core DNA, including compact designs, high-refresh AMOLED displays and similar camera hardware. The S26 does introduce a handful of meaningful updates, however, including a slightly larger battery and newer software out of the box. Those changes also come with a higher starting price: the Galaxy S26 begins at $899.99 compared to the S25’s $799.99 launch price. The entry model now includes 256GB of storage instead of the S25’s base 128GB. Here’s how the Galaxy S26 compares with last year’s Galaxy S25 on paper and whether the newer model is worth your attention.

Galaxy S26 vs. Galaxy S25: Design, display and performance

Physically, the Galaxy S26 stays very close to the design Samsung established with the S25. You still get a compact handset with flat edges, an aluminum frame and IP68 water and dust resistance. The overall look and feel should be immediately familiar to anyone who used last year’s phone.

The display story is similarly steady. Both phones use Samsung’s Dynamic AMOLED 2X panels with adaptive refresh rates up to 120Hz, and the S25 is rated for peak brightness of up to 2,600 nits. In everyday use, whether you are scrolling, gaming or watching video, the viewing experience should feel broadly similar between the two devices.

Under the hood, the Galaxy S25 is powered globally by Qualcomm’s Snapdragon 8 Elite for Galaxy chipset paired with 12GB of RAM. The Galaxy S26 continues to target flagship-class performance. While Samsung has made internal refinements, overall speed should remain firmly in high-end territory for routine tasks, multitasking and mobile gaming.

On the software front, the S25 launched with Android 15 and One UI 7, while the Galaxy S26 ships with a newer version of Samsung’s software out of the box. As usual, the older model is expected to receive updates over time, which may narrow the long-term software gap.

Galaxy S26 vs. Galaxy S25: Cameras

Samsung has not dramatically reshuffled the base Galaxy camera hardware. The Galaxy S25 features a triple-camera setup built around a 50-megapixel main sensor, a 12MP ultrawide and a 10MP telephoto with 3x optical zoom, along with a 12MP front camera.

The Galaxy S26 largely sticks with the same proven approach, which suggests image quality should remain broadly consistent in good lighting. As is often the case with Samsung’s year-to-year updates, any meaningful gains are likely to come from image processing improvements rather than brand-new sensors.

For most people, that means the S26 should deliver the punchy, reliable photos Samsung flagships are known for, but Galaxy S25 owners should not expect a dramatic leap in camera hardware.

Galaxy S26 vs. Galaxy S25: Battery life and charging

Battery capacity is one area where the Galaxy S26 makes a measurable change. The Galaxy S25 uses a 4,000mAh battery, while the Galaxy S26 increases that to 4,300mAh. That modest bump should translate into slightly longer endurance in day-to-day use, though real-world gains will depend on efficiency improvements and individual usage patterns.

Charging speeds remain largely unchanged. The Galaxy S25 supports up to 25W wired charging, up to 15W wireless charging and 4.5W reverse wireless charging, and the Galaxy S26 stays in the same general range.

Galaxy S26 vs. Galaxy S25: Software and AI

This year, Samsung is putting more emphasis on Galaxy AI, even on the base Galaxy S26. While many of the headline features are aimed at the Ultra and Plus models, the standard S26 still picks up several practical upgrades.

One of the more useful additions is Document Scan, which uses AI to clean up scans by automatically removing distortions, fingers and creases. It can also bundle multiple images into a single PDF, making it easier to digitize receipts, notes or forms without extra editing.

Samsung is also expanding its proactive assistant features. Now Brief becomes more personalized on the S26, surfacing reminders and updates based on your activity throughout the day, while the new Now Nudge system can suggest relevant content at the right moment. For example, if someone asks for photos from a recent trip, the phone can proactively surface matching images from your gallery instead of making you search manually.

Search is getting smarter as well. Circle to Search with Google now supports enhanced multi-object recognition, allowing you to identify several items in an image at once. Samsung is also upgrading Bixby into a more conversational assistant, and the S26 supports third-party agents such as Gemini and Perplexity for handling more complex, multi-step tasks through voice commands.

Security and privacy features are expanding in the background too. The Galaxy S26 introduces AI-powered Call Screening to summarize unknown callers, along with new Privacy Alerts that warn when apps request sensitive permissions. Samsung is also extending its post-quantum cryptography protections deeper into the system, backed by the company’s Knox security platform and seven years of promised security updates.

Galaxy S26 vs. Galaxy S25: How to choose

If you already own a Galaxy S25, the Galaxy S26 looks like a fairly iterative update. The core experience, including performance, display quality and camera hardware, remains very similar.

The main tangible upgrade is the slightly larger battery, along with newer software out of the box. For most S25 owners, that alone probably is not a compelling reason to upgrade. However, if you are coming from an older Galaxy phone or buying fresh, the Galaxy S26 is the more future-proof pick simply because it starts one generation ahead in Samsung’s update cycle and packs the larger battery.

As usual with Samsung’s yearly refreshes, the real decision may come down to pricing and discounts. If the Galaxy S25 sees significant price cuts, it could remain the better value. But at similar prices, the Galaxy S26 is the safer long-term buy.
