Galaxy S25 Ultra Design
The Samsung Galaxy S25 Ultra stands out as the largest and most premium model of the Galaxy S25 series. This year, the design concept, which replaces sharp and square lines with more rounded corners, takes the device to a different point from previous models. This change makes the S25 Ultra more compatible with the general design line of the Galaxy S series, rather than just a continuation of the Galaxy Note. The Galaxy S25 Ultra, the only model in the series that offers S Pen support, offers an ideal option especially for artists, content creators and users who like to take notes. Thanks to its large screen and sensitive pen, it provides a unique experience for digital drawing, note-taking and productivity-oriented works. The Samsung Galaxy S25 Ultra stands out as one of the most advanced Android phones of 2025 with its innovative design, powerful hardware and integrated S Pen stylus.
The Samsung Galaxy S25 Ultra is lighter and thinner than its predecessor, the Galaxy S24 Ultra (6.40 x 3.11 x 0.34 inches, 8.22 ounces), with dimensions of 6.41 x 3.06 x 0.32 inches (HWD) and a weight of 7.69 ounces (218 grams). These small differences make the device more ergonomic and more comfortable for daily use. If the large screen and body structure of the S25 Ultra are too much for you, the Galaxy S25+ may be an ideal alternative. With dimensions of 6.24 x 2.98 x 0.29 inches and a weight of 6.70 ounces (190 grams), it offers the same powerful features while promising a more compact experience.
Compared to rival models such as the Apple iPhone 16 Pro Max and Google Pixel 9 Pro XL, the dimensions of the S25 Ultra do not differ significantly. It has similar physical dimensions to the iPhone 16 Pro Max (6.42 x 3.06 x 0.32 inches, 7.99 ounces) and Pixel 9 Pro XL (6.40 x 3.00 x 0.30 inches, 7.80 ounces). The Samsung Galaxy S25 Ultra has similar dimensions to its rivals, but stands out with its thinner and lighter design. It remains a premium option for those looking for a big-screen experience.
The Galaxy S25 Ultra stands out as the only model in the series with a titanium frame. In addition, it uses the new generation Corning Gorilla Armor 2 glass on its screen. According to Samsung, this glass provides 29% better impact resistance compared to the first generation Gorilla Armor in the Galaxy S24 Ultra, thus offering stronger protection against drops and cracks. The front glass minimizes glare with its anti-reflective properties, while the Corning Gorilla Glass Victus 2 rear panel increases durability. The Galaxy S25 and S25+ models, on the other hand, come with an aluminum frame and Gorilla Glass Victus 2 glass panels, which makes the Ultra model more premium and durable. The Samsung Galaxy S25 Ultra offers its users a high level of durability as the most durable Galaxy S series model with its titanium frame and Gorilla Armor 2 protection.
The Galaxy S25 Ultra, like all models in the S25 and S24 series, has an IP68 certification. This certification shows that the device is resistant to dust and water. According to Samsung, the S25 Ultra can continue to operate in water up to 1.5 meters (5 feet) deep for 30 minutes. The IP68 certification is a standard feature for premium flagship phones, and rival models such as the iPhone 16 Pro Max and Google Pixel 9 Pro XL also offer the same level of water and dust resistance. The Samsung Galaxy S25 Ultra provides strong protection against external factors such as spills, rain or dust in daily use, and can be used safely even in difficult conditions.
The S25 Ultra retains its rear camera design, offering four round lenses and a laser focus module. There are volume and power buttons on the right edge, two microphone holes on the top edge, and the S Pen, speaker, USB-C (v3.2) port and SIM card slot on the bottom edge. The device does not have a microSD card slot or headphone jack.
Galaxy S25 Ultra Color Options
The S25 Ultra is available in four main colors: Titanium Black, Titanium Gray, Titanium Silverblue, and Titanium Whitesilver. Exclusive to Samsung’s website, there are Titanium Jadegreen, Titanium Jetblack, and Titanium Pinkgold. The colors are only visible on the rear glass panel, while the frame is finished with a chrome finish. Only the Titanium Jetblack model has a black frame. The S Pen is designed to match the back glass color of the device. For those expecting bolder tones, the absence of options such as Titanium Orange and Titanium Violet may be a drawback.
Galaxy S25 Ultra Security
The S25 Ultra offers the most secure biometric authentication method with its ultrasonic fingerprint sensor integrated under the display. This sensor, which works quickly and consistently, provides secure login. The device also has a face unlock feature, but it is not secure enough for sensitive applications such as banking. Considering that Apple and Google have been offering secure face recognition technologies for years, Samsung is also expected to take a step in this regard.
Bigger and Brighter Display Design
The S25 Ultra features the largest Galaxy S display yet, with a 6.9-inch LTPO Dynamic AMOLED 2X display. It offers a sharp, smooth, and bright display with a resolution of 3,120 x 1,440 pixels, a variable refresh rate of 120Hz, and a maximum brightness of 2,600 nits. The display is 0.1-inch larger than its predecessor, and the bezels have been reduced by 15%, making the front of the phone almost entirely screen. While the pixel density has dropped slightly, the overall image quality and fluidity remain at the same level.
Galaxy S25 Series and Competitors: Screen Comparison

Pixel 9 Pro XL: 6.8-inch screen, 2,992 x 1,334 pixels, 120Hz refresh rate, 3,000 nits brightness
The Galaxy S25 Ultra offers a strong option against its rivals with its big screen, high resolution and 2,600 nits brightness, but the Pixel 9 The Pro XL’s 3,000 nits of brightness may be superior in terms of screen visibility.
The S25 Ultra’s screen provides a visually impressive experience by offering sharp details and smooth performance. It is ideal for outdoor use because it offers a clear image even in sunlight thanks to its anti-reflective coating and high brightness. It effectively blocks out ambient light, providing a comfortable screen experience in all conditions.
S Pen Experience and Compatibility
The S25 Ultra’s S Pen feels and functions the same as its predecessor, supporting up to 4,096 levels of pressure sensitivity. The new S Pen costs $49.99, but the previous-generation Bluetooth-enabled S Pen is not compatible with this model, so wireless features like Air Actions aren’t possible with the old pen.
Galaxy S25 Ultra: RAM and Storage Options
All Galaxy S25 models come with 12GB LPDDR5x RAM, but it doesn’t offer an increase over the previous generation. Competing models like the Asus ROG Phone 9 (16GB) and RedMagic 10 Pro (24GB) make a difference with their higher RAM capacity. On the storage side, the S25 Ultra offers 256GB, 512GB, and 1TB options with fast UFS 4.0 technology. There’s a wide range available for users looking for high storage capacity, and the RAM amount is more limited compared to some rivals.
Galaxy S25 Ultra: Battery and Charging Performance
The S25 Ultra has the same 5,000mAh battery as its predecessor, and supports 45W wired charging and 15W wireless charging. 4.5W reverse wireless charging is also available, but it’s quite slow. No charging adapter is included in the box, so users will need to provide their own.
Battery Performance in Real-Time Use:
Samsung says: 31 hours of usage time (720p video playback, LTE connection)
In independent tests: YouTube HD video playback time over Wi-Fi at full brightness: 14 hours and 15 minutes
Galaxy S24 Ultra: 14 hours and 10 minutes
Pixel 9 Pro XL: 12 hours and 25 minutes
iPhone 16 Pro Max: 22 hours and 5 minutes (Longest usage time)
The Galaxy S25 Ultra’s battery performance is almost the same as its predecessor, and it lags behind its rivals, especially the iPhone 16 Pro Max. However, Samsung’s optimized software and strong battery management provide a satisfying experience in daily use.
Top-Level Performance and Powerful AI Processing
All Galaxy S25 models are powered by the Qualcomm Snapdragon 8 Elite for Galaxy processor. While previous “for Galaxy” chips were simply overclocked versions, this year Samsung is adding a dedicated application processor, allowing the device to perform more AI processing directly on the phone.
According to Samsung, the new chip:
– 40% more powerful NPU (Neural Processing Unit)
– 37% more CPU performance
– 30% better GPU performance
A 40% larger vapor chamber compared to the Samsung Galaxy S24 Ultra improves heat management, providing a long-term performance boost. The S25 Ultra is poised to be one of the most powerful Android phones of 2025, offering high speeds and stability even in the most demanding tasks.
Galaxy S25 Ultra: Charging Speed and Qi2 Support
Samsung continues to lag behind its competitors in terms of charging technology. While the S25 Ultra still supports 45W wired charging, rival brands have switched to much faster charging solutions such as 80W and 100W. Although the S25 Ultra fully charges in 15 minutes faster than the previous model, it is still slow compared to its competitors. The fact that Samsung has not made any major changes to its battery capacity further strengthens the expectation that it will increase charging speeds.
On the wireless charging side, the S25 Ultra supports the Qi2 standard, but does not offer a fully integrated system. While Qi2 is a wireless charging standard that provides magnetic alignment, similar to Apple’s MagSafe technology, Samsung did not include magnetic components in the device. For this reason, it is necessary to use a magnetic case to get the full performance of Qi2-supported chargers. This means an additional cost.
Galaxy S25 Ultra: Connectivity Technologies and 5G Performance
The S25 Ultra offers the latest technologies on the connection side, providing a fast and uninterrupted experience. The device supports all frequency bands of 5G, while offering a stronger and more stable internet connection with Wi-Fi 7. Thanks to Bluetooth 5.3, connection stability is increased with lower energy consumption. It also allows the use of a single physical SIM card with eSIM support.
The device’s 5G performance is quite good in real use. In tests conducted on T-Mobile’s 5G UC network in New York, 533 Mbps download and 59.3 Mbps upload speeds were reached. In the same test, the Pixel 9 Pro XL, despite offering a higher download speed, fell far behind in upload speed. It is expected to show similar performance on other major carriers such as AT&T and Verizon. In Wi-Fi connection tests, the S25 Ultra fell behind the Pixel 9 Pro XL despite offering high speeds. It is seen that the Pixel offers a higher performance, especially in download speeds. However, it can be said that the difference is not big enough to be felt in daily use.
Voice and Call Quality
Samsung continues to improve the sound quality in the S25 Ultra. The device’s dual speaker system reaches a maximum level of 96.3dB, providing a sound output that can comfortably play music in a small room. Although the speaker volume is quite high, there is a limitation expected from phone speakers in terms of deep bass. For a richer music experience, using a quality Bluetooth headset may be a better option.
In terms of call quality, the S25 Ultra performs quite well. The sound is transmitted clearly and understandably during phone calls. Advanced algorithms are used to filter background noise, providing a clear call experience even in crowded environments. It is seen that it suppresses external ambient sounds well, especially in urban use.
Galaxy S25 Ultra: Camera Performance
The S25 Ultra maintains the successful system of its predecessor on the camera side, while making a significant upgrade, especially in the ultra-wide-angle camera. The ultra-wide-angle camera, which has been increased from 12MP resolution to 50MP, offers more detail, providing a significant improvement in both landscape shots and macro photos. Thanks to the new macro mode, it is possible to capture surface textures and small details better.
The main camera offers high levels of detail with 200MP resolution and f/1.7 aperture, while the telephoto cameras stand out with their powerful optical zoom capabilities. 3x and 5x optical zoom shots provide sharp and detailed results. However, extreme zoom modes such as 100x Space Zoom often look soft and artificial due to the combination of optical and digital cropping. Portrait mode provides successful results in background separation. While portraits taken with the rear camera offer a natural depth effect, the front camera can sometimes soften fine details too much and produce incorrect blurring. In difficult areas such as transparent objects and eyeglasses, the algorithm is generally seen to perform well.
Overall, the S25 Ultra offers a top-notch camera experience. Samsung’s image processing algorithms are quite successful in terms of color accuracy and dynamic range. It can be said that features such as extremely high resolution and 100x zoom are more than enough for daily use.
Galaxy S25 Ultra: New Smart Features with One UI 7 and Galaxy AI
Samsung offers the S25 Ultra with Android 15 and the new One UI 7 interface. The company promises to provide operating system and security updates for the device for 7 years, following an update policy that no other manufacturer except Google’s Pixel series does. This long-term support stands out as a significant advantage that will keep the device up to date for a longer period of time.
On the artificial intelligence side, Samsung is adding many new features with Galaxy AI. Thanks to the Google Gemini integration, it becomes possible to make smart directions between different applications. For example, you only need to give a single command to find pet-friendly restaurants in a certain city and send them as a message to a friend. The new Now Brief and Now Bar features make the user experience smarter by showing the weather, calendar events and news on a single screen. Circle to Search technology allows you to instantly search by selecting any text or image on the screen. A new search feature has also been added that analyzes the sounds in videos and recognizes songs or speeches.
The AI-supported editing tools in the Gallery application also stand out. Audio Eraser removes unwanted sounds from videos, while Best Face can change facial expressions in moving photos. Generative Edit can now remove objects and create backgrounds without requiring an internet connection. Samsung also offers a call summary feature on the Galaxy S25 Ultra. Conversations recorded during phone calls are analyzed and summarized by artificial intelligence, highlighting keywords. This feature can be especially useful for business meetings.
Samsung Galaxy S25 Ultra is at the Top of Android!
The S25 Ultra represents the highest level in the Android ecosystem with its powerful hardware, advanced camera systems and smart software features. Samsung’s 7-year update support makes the device attractive to use in the long term. The fact that the charging speed is still behind its competitors and Qi2 support is not fully integrated may be a shortcoming for some users. Alternatively, models such as the Galaxy S25+ or Pixel 9 Pro XL offer more affordable options. With S Pen support, a large screen and high-level AI integration, the S25 Ultra continues to be the best choice for those looking for a premium experience.
