Last year’s Samsung Galaxy S24 Series made headlines with its in-built AI features named Galaxy AI, and this year’s phone models take AI to the next level with “smarter” technology and new features known as Now Brief. AI is now the perfect mobile assistant as you can ask it to do several things at once without switching between apps, the same way you would naturally ask a person. Galaxy AI’s latest Now Brief feature also helps organise your day by giving personalised summaries of your daily routine, schedules, and other mobile information.

Alongside Now Brief, Galaxy AI also sees upgrades in its security, with on-device personalised AI data now being secured with Knox Vault encryption. You can also now personally adjust their privacy settings and manage data access app-by-app to protect your information.

Unlike previous years where processors differed between the three Galaxy S series models, the Galaxy S25 features the same advanced processor across the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra – the Snapdragon 8 Gen 4. As three of the first phones in the smartphone market to run on the new Snapdragon 8 Gen 4 processor, you can expect excellent performance from all three flagship phones.

Below are a few more specific differences between the Samsung Galaxy S25 Series and the previous year’s Galaxy S24 line-up.

Aside from the significant processor upgrade, the Samsung Galaxy S25 and Galaxy S24 are largely the same hardware-wise, and their main differences lie in sizing and colourway. The latest model is slightly slimmer, lighter, and smaller than its predecessor³. A much-appreciated answer to the smaller-phone sentiment, the Galaxy S25 is perfect for those looking for a pocket-friendly phone that’s not a struggle to hold for long periods of time.

The Galaxy S25 is also available in neutral and classic colours this year, including Icyblue, Navy, Silver Shadow, and Mint.

The biggest difference between the Samsung Galaxy S25+ and Galaxy S24+ is the new processor upgrade. Jumping from the Exynos 2400 to the latest Snapdragon 8 Gen 4 chipset that’s used to power even laptops, you can expect incredible power and performance on the Galaxy S25+⁴. Despite traditionally being a more basic model that focuses on the everyday mobile experience, the Galaxy S25+’s new processor means it can deliver Ultra-level like performances with solid cameras and AI capabilities to boot.

If you’re looking for a new phone with a large display, the Galaxy S25 Ultra is certainly a worthwhile option to consider. Even bigger than the previous Galaxy S24 Ultra’s 6.8-inch display, the Galaxy S25 Ultra’s 6.9-inch display makes streaming, gaming, and browsing an even more immersive visual experience⁵. Not only that, the upgraded Snapdragon 8 Gen 4 processor also means better graphics and power efficiency so you can enjoy entertainment on your phone in higher quality and for longer.

Samsung has heard and responded to fan requests for a more pocket-friendly phone with the new Galaxy S25 Ultra, as despite having a larger display, the latest phone is actually lighter and slimmer than the previous model. The smartphone’s Corning Gorilla Armour⁶ and IP68 water and dust rating⁷ also means you can get a bit rough with it, without having to worry about durability.
