About the Samsung Galaxy S25 Ultra
The Samsung Galaxy S25 Ultra is Samsung's most capable smartphone, combining the raw power of the Snapdragon 8 Elite chipset with a refined titanium design and a camera system built for serious photography. Released in February 2025, it features a slightly larger 6.9-inch QHD+ Dynamic AMOLED display with slimmer bezels and rounded corners that make the phone more comfortable to hold than the angular S24 Ultra. The headline camera upgrade is a new 50MP ultrawide sensor that replaces the old 12MP module, delivering four times more detail in macro and wide-angle shots, while the proven 200MP main sensor and dual telephoto lenses remain. Performance is outstanding thanks to the custom Snapdragon 8 Elite for Galaxy chip, and Samsung's AI capabilities have matured with cross-app actions, smarter photo editing, and on-device processing. The 5,000mAh battery with 45W wired charging and Qi2 compatibility keeps you going through demanding days, and the S Pen remains tucked neatly into the body for note-taking and precision tasks. With seven years of updates, IP68 protection, and Gorilla Armor 2 glass, the S25 Ultra is built for users who want the absolute best Android phone available and plan to keep it for years.
