🎨 Design & Build Quality
The S25 Ultra features smoother rounded edges and a premium titanium frame with second-generation Gorilla Glass Armor for superior scratch and drop resistance. At 219g, it's noticeably lighter than the S24 Ultra (232g), making extended use more comfortable. The slimmer bezels expand the screen to an impressive 6.9 inches while actually making the phone easier to hold one-handed. Available in Titanium Black, Titanium Gray, Titanium Blue, and Titanium Violet, each finish showcases the premium materials beautifully.
📺 Display Excellence
Samsung continues its display dominance with a QHD+ (3120 x 1440) Dynamic AMOLED 2X panel delivering an astounding 2,600 nits peak brightness - the brightest smartphone display we've ever tested. The adaptive 1-120Hz refresh rate ensures buttery-smooth scrolling while conserving battery during static content. Color accuracy is perfect out of the box with 100% DCI-P3 coverage, and the anti-reflective coating dramatically improves outdoor visibility. Whether you're reading in bright sunlight or watching HDR content in a dark room, this display performs flawlessly.
⚡ Performance Powerhouse
Powered by the custom Snapdragon 8 Elite "for Galaxy" chip built on 3nm process, the S25 Ultra delivers desktop-class performance. Our Geekbench 6 testing showed 37% faster CPU scores and 40% improved GPU performance compared to the S24 Ultra. The enlarged vapor chamber cooling system prevents throttling even during extended gaming sessions - we played Genshin Impact at max settings for 45 minutes with zero performance drops. With 12GB RAM standard (16GB on 512GB/1TB models), multitasking is seamless with dozens of apps staying active in memory.
📷 Advanced Camera System
The quad camera setup features a 200MP main sensor with OIS, significantly upgraded 50MP ultra-wide (f/1.9, up from 12MP), 10MP 3x telephoto, and 50MP 5x periscope telephoto. In our testing, the main camera captured stunning detail with excellent dynamic range in daylight. The improved ultra-wide lens is a game-changer - significantly sharper corners and better low-light performance. Zoom capabilities are class-leading with excellent 10x shots and usable 30x images. New features include Virtual Aperture control for adjustable background blur and LOG video mode for professional color grading in post-production.
🔋 Battery & Charging
The 5,000mAh battery consistently delivered 6-7 hours of screen-on time in our testing with moderate to heavy use, reliably lasting from morning to bedtime with 25-35% remaining. Supports 45W wired fast charging reaching 50% in 30 minutes and full charge in 65 minutes. Wireless charging maxes out at 15W, or you can use Samsung's new magnetic case for Qi2 compatibility. AI-powered battery optimization learns your usage patterns to pre-load frequently used apps and manage background processes intelligently.
