Samsung Galaxy S25 Ultra Kenya Review: Flagship Redefined

Samsung has once again delivered a masterpiece with the Samsung Galaxy S25 Ultra. Here in Kenya, it lives up to the Ultra name by blending a stunning design, blistering performance, and pro‑grade camera capabilities. In this hands‑on review, we’ll examine how the S25 Ultra performs in everyday life, from its premium build quality to its intelligent software, and why it stands out among flagship phones.

Build & Design: Solid Yet Elegant

When you first pick up the Galaxy S25 Ultra, well, its titanium frame immediately conveys durability without feeling overly heavy. Despite tipping the scales at around 218 grams, the device never becomes cumbersome, thanks to its balanced weight distribution and gently curved edges. Samsung has refined the glass back with a matte finish, which resists fingerprints and adds a tactile sense of luxury. Moreover, the IP68 rating provides peace of mind against accidental splashes or dust ingress, making it ideal for both Nairobi’s unpredictable weather and days spent outdoors in the Kenyan countryside.

The display is equally impressive. Spanning 6.9 inches, the Dynamic LTPO AMOLED 2X panel offers vivid color reproduction and deep blacks. More importantly, the adaptive 120 Hz refresh rate adjusts dynamically based on content, conserving battery when you’re reading emails and ramping up for gaming or scrolling through social media. With peak brightness levels reaching 2,600 nits, the screen remains legible even under direct equatorial sun. As a result, whether you’re browsing maps in Mombasa midday or streaming a movie back in your hotel room, you’ll enjoy a consistently clear and smooth visual experience.

Performance: Unmatched Flagship Power

Under the hood, the Galaxy S25 Ultra runs on the Snapdragon 8 Elite chipset, built with an advanced 3 nm process. In daily use, that translates to instant app launches, seamless multitasking, and frame‑rate stability during intense gaming sessions. Samsung’s enhanced vapor‑chamber cooling system does an excellent job of dissipating heat, so you won’t encounter annoying performance dips even during marathon video calls or extended gameplay.

The standard configuration pairs 12 GB of RAM with 256 GB of internal storage, ensuring that apps remain in memory for quick access. For power users, Samsung offers variants with up to 1 TB of storage, providing ample room for high‑resolution video footage, large game files, and extensive photo libraries. Running on the impressive Android 15 with One UI 7, the Samsung user interface feels polished and intuitive. Animations flow smoothly, and the layout remains uncluttered. New AI features seamlessly integrate into the system, making everyday tasks more efficient without overwhelming the user.

Camera: Pro‑Level Versatility in Every Shot

Samsung’s S‑series is known for pushing mobile photography boundaries, and the S25 Ultra proves no exception. At its core is a 200 MP main sensor equipped with optical image stabilization, capturing extraordinary detail in well‑lit conditions. Accompanying that is a dedicated 10 MP telephoto lens for 3× optical zoom, allowing you to isolate subjects without losing quality. For even greater reach, Samsung includes a 50 MP periscope telephoto lens offering 5× optical zoom and up to 100× digital zoom, making distant subjects appear surprisingly close. An upgraded 50 MP ultra‑wide sensor replaces the previous generation’s lower‑resolution module, ensuring expansive landscapes and group photos retain sharpness and dynamic range. Up front, the 12 MP selfie camera balances skin tones and background detail for flattering portraits.

In practical tests, daytime shots showcase vibrant colors and excellent dynamic range, while night mode intelligently merges multiple exposures to suppress noise and protect highlights. Video recording supports up to 8K resolution at 30 frames per second, or 4K at 60 fps, with built‑in stabilization that keeps footage steady on the move. Advanced AI tools such as Audio Eraser help isolate your subject’s voice by minimizing background noise, and Generative Edit lets you remove unwanted elements from a scene directly on the device. Together, these features elevate both photo and video performance to professional‑grade levels.

Galaxy AI: On‑Device Smarts for Real‑World Productivity

Samsung’s new Galaxy AI suite brings meaningful intelligence to everyday tasks. For instance, the Circle to Search feature allows you to tap any text, be it an address, phone number, or URL and instantly look it up, dial it, or navigate to it without leaving the current app. The integration of Google’s Gemini Assistant into One UI means you can summon an AI companion with a simple long‑press of the power button, using natural language to draft emails, summarize articles, or plan your day. The Now Brief widget offers a customizable morning briefing with weather forecasts, calendar events, and breaking news, plus an evening digest that recaps top stories and upcoming reminders.

On the creative side, Drawing Assist helps convert rough sketches into polished illustrations, while Portrait Studio applies professional‑style lighting effects for studio‑quality portraits. Crucially, all these AI processes run locally on the device, so your data never leaves the phone. Samsung also commits to seven years of security updates and feature enhancements, ensuring that your AI tools improve over time without compromising privacy.

Battery & Charging: All‑Day Reliability

Powering the Samsung Galaxy S25 Ultra is a robust 5,000 mAh battery, which in our mixed‑use tests lasts comfortably from morning until night. Typical usage, including messaging, social media browsing, photography, and occasional gaming easily extends beyond a full day. When you do need to top up, the phone supports 45 W wired charging, achieving roughly 65% battery in 30 minutes, and 25 W wireless charging for clutter‑free power‑ups. Reverse wireless charging lets you share battery power with compatible accessories such as earbuds or another phone, a handy feature when you’re on the go. Samsung’s focus on balanced charging speeds helps reduce long‑term battery degradation, so you can expect consistent performance over years of use.
