The Samsung Galaxy S25 Ultra represents the pinnacle of Android smartphone technology in 2025. With groundbreaking specifications, refined design, and powerful AI capabilities, it's Samsung's most ambitious flagship yet. Here's everything you need to know about the S25 Ultra and why OgaBassey is your best choice to buy it in Nigeria.
Design and Display: Premium Craftsmanship
The Galaxy S25 Ultra continues Samsung's tradition of premium design with a refined titanium frame that's both lighter and more durable than previous generations. The device features:
- 6.9-inch Dynamic LTPO AMOLED 2X display with QHD+ resolution (3120 x 1440)
- 120Hz adaptive refresh rate for buttery-smooth scrolling
- Corning Gorilla Armor with enhanced scratch resistance
- Peak brightness of 2,600 nits for excellent outdoor visibility
- Built-in S Pen with improved latency for natural writing experience
The slightly curved edges make the large display easier and more comfortable to hold, while the matte finish on the back reduces fingerprints and adds a sophisticated look.
Performance: Snapdragon 8 Elite Powerhouse
At the heart of the S25 Ultra is Qualcomm's latest Snapdragon 8 Elite processor, built on a 3nm process. This chip delivers:
- 30% better CPU performance compared to Snapdragon 8 Gen 3

- 12GB or 16GB LPDDR5X RAM options for seamless multitasking

Whether you're editing 8K video, playing demanding games, or running multiple apps simultaneously, the S25 Ultra handles everything with ease.

The camera system is where the S25 Ultra truly shines. Samsung has refined its already impressive photography capabilities:

Battery Life and Charging
The S25 Ultra packs a 5,000mAh battery that easily lasts a full day of heavy use. Charging capabilities include:
- 45W wired fast charging (0-65% in 30 minutes)
- 15W wireless charging
- Qi2 wireless charging support (requires a compatible case)
- Reverse wireless charging to charge accessories
- Optimized battery management with AI-powered power saving
Software: One UI 7.0 with Galaxy AI
Running on One UI 7.0 based on Android 15, the S25 Ultra offers:
- 7 years of major OS updates and security patches
- Galaxy AI features:
- Real-time call translation
- AI photo editing tools
- Smart text suggestions
- Enhanced voice typing
- Circle to Search with Google
- Cross-app actions and personalized assistance
- Improved multitasking with better split-screen and pop-up view

While these AI capabilities are ambitious and powerful, some early users have reported occasional inconsistencies, suggesting there is room for refinement in future software updates. However, the core functionality remains a significant step forward in on-device intelligence.
S Pen: A Controversial Change
The S Pen remains a cornerstone of the Ultra experience, offering unparalleled precision for note-taking and creativity. However, the S25 Ultra introduces a controversial change: the removal of Bluetooth functionality from the S Pen. This means that features like using the S Pen as a remote camera shutter or for air gestures are no longer available. While the core writing and drawing experience is as good as ever, this decision has alienated some long-time fans who relied on its remote capabilities.
