At the heart of the Galaxy S26 Ultra is the customised Snapdragon 8 Elite Gen 5 for Galaxy mobile platform. Samsung describes it as its most powerful Galaxy S-series processor to date, with improved CPU, GPU and NPU performance designed to accelerate gaming, photography and on-device AI.

The display is one of the phone's defining features. Its 6.9-inch QHD+ Dynamic AMOLED 2X panel runs at an adaptive 1–120Hz refresh rate, reaches up to 2,600 nits peak brightness and is protected by Corning Gorilla Armor 2.

The S26 Ultra also introduces Samsung's new built-in Privacy Display. When activated, the display remains clear from directly in front while limiting visibility from side angles, helping protect messages, passwords, notifications and sensitive information in public places. Samsung lets users activate privacy for the entire display or customise it for selected apps and notifications.

Photography is handled by a flagship four-camera rear system consisting of:

• 200MP Wide – f/1.4
• 50MP Ultra-Wide – f/1.9
• 50MP Telephoto – 5x Optical Zoom, f/2.9
• 10MP Telephoto – 3x Optical Zoom, f/2.4

with a 12MP front-facing camera.

Samsung widened the aperture of the main 200MP camera to f/1.4, which it says allows substantially more light into the sensor for improved low-light photography and Nightography video. The 50MP 5x telephoto lens has also been improved for brighter zoom photography in difficult lighting.

Battery capacity remains a large 5,000mAh typical, with Samsung rating the phone for up to 31 hours of video playback. Super Fast Charging 3.0 increases compatible wired charging to 60W, allowing the battery to reach approximately 75% in around 30 minutes with the appropriate adapter.

The Galaxy S26 Ultra also retains one of the Ultra series' signature features: a built-in S Pen stored directly inside the handset, making the phone suitable for handwritten notes, precise editing, signatures and productivity tasks without requiring a separate stylus.
