Features

New and improved One UI 5.1

Compatible with the S Pen

5,000mAh battery and Super-Fast charging

6.8-inch QHD+ Dynamic AMOLED 2X Display

Your Galaxy, your way

The Galaxy S23 Ultra boasts a fresh look, both outside and in. The new and improved One UI 5.1 lets you customise your whole experience. From lock screen and wallpaper designs, to how the clock and notification bar appear. And, all the core Samsung apps have had a facelift too, for a fresh look throughout.

Perfect precision with S Pen

The Galaxy S23 Ultra puts the power of an editing suite in the palm of your hand. The S Pen lets you edit the smallest details with absolute precision, so you can leave the world of pinching and prodding behind, and go pro. The fine nib lets you create complex selections in your photos and trim video frames with extreme accuracy. And when you need to get in the frame too, control the camera shutter and timer remotely using the S Pen’s button, connected to the S23 Ultra via Bluetooth.

Next-level performance and Super-Fast charging

Nothing will hold you back with the most powerful mobile chip in the Galaxy S Series yet, the Qualcomm Snapdragon 8 Gen 2 for Galaxy Processor. It makes small work of big tasks. And, with a huge 5000mAh (typical)* Battery with Super-Fast charging**, it means you’ll never be caught short.

*Typical values tested under third-party laboratory condition. Rated minimum capacity is 4,855mAh.

**45W Travel Adapter sold separately.

Designed to be epic

With an expansive 6.8-inch QHD+ Dynamic AMOLED 2X Display and standout brightness, the ultra-immersive Galaxy S23 Ultra is easy on the eyes. The adaptive Vision Booster technology automatically adjusts to suit your environment. So, whether you’re in the bright morning sun, or travelling in and out of tunnels on the train, you’ll always have distraction-free viewing. The big picture experience is made even better with a refresh rate up to 120Hz, for silky smoothness when scrolling. And it’s built to be tough, with the latest and toughest Corning® Gorilla® Glass Victus® 2 to protect the S23 Ultra’s front and back, plus an Armour Aluminium frame.
