Samsung continues to refine its flagship lineup, and the Galaxy S25 Ultra has become a true technological breakthrough. The South Korean giant has managed to combine innovative technologies, advanced artificial intelligence capabilities, and professional camera functionality in one premium device.
Design and Ergonomics
The Galaxy S25 Ultra features an updated design with flatter side edges and even thinner bezels around the display. The body is made of high-strength Armor Aluminum 2.0 alloy with a matte back panel of Corning Gorilla Glass Victus 3, resistant to scratches and damage.
Despite the impressive 6.9-inch screen, Samsung engineers have made the smartphone more compact compared to its predecessor – the width has been reduced by 1.8 mm, and the thickness is only 8.3 mm. This has positively impacted the device’s ergonomics, making it more comfortable to hold.
The smartphone is available in five color variants: Titanium Black, Titanium Gray, Titanium Blue, Titanium Green, and an exclusive Titanium Red. It has IP68 water and dust resistance, allowing the device to withstand submersion in fresh water up to 1.5 meters for 30 minutes.
Next-Generation Display
The Galaxy S25 Ultra is equipped with a 6.9-inch Dynamic AMOLED 3.0 display with Quad HD+ resolution (3200 × 1440 pixels) and advanced LTPO 4.0 technology, which dynamically adjusts the refresh rate from 1 to 144 Hz depending on the content.
The screen’s peak brightness reaches a record-breaking 2500 nits in peak mode and 1300 nits in regular outdoor use, ensuring excellent visibility even in direct sunlight. Support for HDR10+ and the DisplayHDR True Black 600 standard guarantees unmatched color accuracy and contrast.
Vision Booster 2.0 technology automatically optimizes saturation, contrast, and other display parameters based on lighting conditions, while the proprietary Eye Comfort Shield reduces blue light levels, minimizing eye strain during prolonged use.
Technical Specifications and Performance
At the heart of the Galaxy S25 Ultra is the latest Qualcomm Snapdragon 8 Gen 4 For Galaxy processor, manufactured using TSMC’s 3-nanometer process. The chipset includes:
- 8-core CPU with a maximum clock speed of 3.4 GHz
- Adreno 750 GPU
- Second-generation NPU with up to 45 TOPS performance
- Enhanced ISP for image processing
The device is available in configurations with 12 or 16 GB of LPDDR5X RAM and 256 GB, 512 GB, or 1 TB of UFS 4.0 storage. The RAM supports RAM Plus technology, which can allocate up to 12 GB of additional virtual memory when needed.
A 5500 mAh battery with 65W fast charging ensures a full day of battery life even with intensive use. A full charge takes just 43 minutes, and 15 minutes of charging is enough to replenish 50% of the battery. The smartphone also supports wireless charging up to 25W and reverse wireless charging up to 10W.
Professional-Grade Cameras
The Galaxy S25 Ultra features a revolutionary camera system with four modules:
- Main camera: 200 MP, ISOCELL HP9 sensor, 1/1.3" size, optical stabilization, f/1.7 aperture

- Telephoto: 50 MP with 3x optical zoom, optical stabilization, f/2.4 aperture
- Periscope camera: 50 MP with 10x optical zoom, optical stabilization, f/3.4 aperture
The front camera features a 40 MP sensor with autofocus and an f/2.2 aperture, capable of recording 4K video at 60 frames per second.
The main camera now supports 8K video recording at 30 frames per second or 4K at up to 120 frames per second. Pro Video mode allows control over all aspects of shooting, including ISO, shutter speed, white balance, and focus.
Adaptive Pixel technology combines multiple pixels into one to improve photo quality in low-light conditions, while Night Mode uses multi-frame capture and processing to produce clear, vibrant images in the dark.
Galaxy AI – Next-Generation Artificial Intelligence
The Galaxy S25 Ultra is Samsung’s first device with full integration of Galaxy AI 2.0 – an artificial intelligence system that operates both on-device and in the cloud. AI features permeate every aspect of the smartphone’s use:
- AI Camera: Automatically detects scenes and objects, optimizing settings in real-time
- ProVisual Engine: Enhances photo quality using AI, reducing noise, improving detail, and dynamic range
- Photo Assist: Offers intelligent photo editing with generative object removal and background filling
- Circle to Search with Bixby Vision: Allows searching for information about objects by circling them on the screen
- Live Translate: Instant text and speech translation in 55 languages, even offline
- AI Note: Converts handwritten notes to typed text, creates summaries, and organizes information
- Chat Assist: Helps craft messages by suggesting text and tone options
Notably, the Galaxy S25 Ultra allows users to choose between on-device or cloud-based AI processing, with detailed privacy settings.
Software and Ecosystem
The smartphone runs on Android 15 with the One UI 7.0 interface, which has seen significant improvements in personalization and performance.
Samsung promises 7 years of operating system and security updates for the Galaxy S25 Ultra, the best in the Android market and matching Apple’s update policy.
