The Galaxy S25 is a flagship phone that boasts a powerful Snapdragon 8 Elite chip, advanced AI features, a stunning set of cameras, and impressive battery life so you can do more, faster, and easier than ever. Available in 7 colours to express yourself, this sleek and premium phone is ideal for everyone from creatives to gamers to professionals alike.

The Galaxy S25 is where you’ll find it all in a thin, streamlined phone. You’ll even be able to fully customise it thanks to the One UI 7, making it primed and ready for advanced personalisation that fits you to a T.

Samsung Galaxy S25: Display

The Samsung Galaxy S25 6.2” screen uses Dynamic AMOLED 2X technology to deliver a full HD+ experience up to 2340 x 1080 resolution. The 16M colour depth and high 120Hz refresh rate mean every video, game, or image you look at is perfectly crisp and vivid, with liquid-smooth transitions that make scrolling a joy and videos look even better.

Samsung Galaxy S25: Camera

The Samsung Galaxy S25 comes with four cameras, including a 50MP main wide-angle camera capable of a 2x optical zoom, a 10MP telephoto camera with 3x optical zoom, and a 12MP ultra-wide camera on the rear and a 12MP selfie camera. Each camera is supercharged with the ProVisual Engine and sensor, which works to take even higher-quality images at faster shutter speeds to reduce blur.

Where the real power comes from is in the AI-powered editing suite. Thanks to the built-in ProScaler, you’ll be able to ramp up the quality of your images even further with a click.

As for video, you’ll be able to shoot in 10-bit HDR, while the advanced AP works to remove noise with expert precision, even in low-light conditions. You’ll even be able to erase unwanted noise and automatically put together videos with Auto Trim.

Samsung Galaxy S25: Battery

The 4000mAh battery allows you to watch up to 29 hours of video nonstop between charges. More impressively, however, the mDNIe technology optimises your battery usage, letting you enjoy even more hours on your phone between charges.

Samsung Galaxy S25: Size, Weight & Feel

The Galaxy S25 comes in at 146.9mm in height, 70.5mm in width, 7.2mm in depth, and just 162g in weight, making it comfortable to hold one-handed. As for how it feels, the armoured aluminium frame and strengthened Corning® Gorilla® Glass Victus® 2 display glass feel incredibly high-end in your hands, while promising enhanced durability and scratch resistance. The phone is also fully water and dust resistant with an IP68 rating, for worry-free use no matter where you are.

Samsung Galaxy S25: Performance

The Samsung Galaxy S25 is powered by the Snapdragon® 8 Elite for Galaxy and further enhanced with integrated Vulkan optimisation and ray tracing to boost its gaming performance. The phone also boasts a larger Vapour Chamber and thermal interface material to keep it cool and working perfectly even during long gaming sessions.

For creatives, the Galaxy S25 relies on the ProVisual Engine, which boosts your ability to capture, view, and edit content right on the phone.
