Real-world feature highlights (what you’ll actually notice)
1) Camera — the new 200 MP main sensor
The 200 MP sensor isn’t just a spec-sheet number: it enables ultra-detailed photos, more aggressive multi-frame noise reduction (excellent at night), and the flexibility to crop without visible detail loss. Samsung’s periscope + telephoto combo gives both long-range reach and 3× for portrait flexibility. The Object-Aware Engine and Nightography improvements produce cleaner low-light video and better subject separation.
2) Display — bright, smooth, efficient
The Dynamic LTPO AMOLED 2X display delivers silky scrolling (1–120 Hz) while saving battery during static content. Peak HDR brightness and HDR10+ support make the S25 Ultra ideal for HDR streaming and mobile gaming. The reduced bezels give a more immersive feel than earlier models.
3) On-device AI and One UI upgrades
One UI 8 (and the S25 family’s software) places several AI features directly on the device so tasks (call assist, audio cleanup, rewriting text snippets, generative image utilities) run locally or with optimized cloud help, speeding up common workflows and preserving privacy. Samsung emphasizes secure on-device storage with Knox features.
4) Battery and charging
A 5,000 mAh battery plus software efficiency is tuned to deliver a full day (and often more) under normal use. 45W wired charging refills the battery much faster than many flagships that still cap out lower. Wireless charging and reverse wireless charging add convenience for earbuds or Galaxy Watch top-ups.
Price & availability (India & global snapshot)
- India official retail: Samsung India lists the S25 Ultra at ₹123,499 (256 GB) to ₹159,499 (1 TB) on Samsung.com; market promotions and festive discounts frequently adjust street pricing.

Who should buy the Galaxy S25 Ultra?
- Mobile photographers & content creators who want the best zoom and detail from a phone.
- Power users who want top performance, S Pen functionality and lots of local storage.
- Privacy-minded users who appreciate on-device AI and enhanced Knox features.
If you prefer smaller phones, lower price, or removable storage, consider the S25 / S25+ or other flagship options.
Quick comparison: S25 Ultra vs S24 Ultra (what changed)
- Camera: 200 MP main sensor on S25 Ultra vs 50 MP main on S24 Ultra — a major leap in pixel count and cropping flexibility.
- Software/AI: S25 Ultra ships with more mature Galaxy AI features and One UI updates, with rollout expanding to older devices later.
- Materials & design: Titanium reinforcement and thinner bezels provide a refined premium feel.
Tips to get the best from your S25 Ultra
- Enable adaptive refresh — let LTPO shift between 1–120 Hz for battery savings.
- Shoot in 200 MP RAW when you need maximum cropping/edits; use multi-frame or night modes for low-light.
- Use Galaxy AI tools for fast cleanups: Audio Eraser for noisy clips and Now Brief for summarising long texts.
- Opt for higher storage if you shoot a lot of 8K/RAW video — the 1 TB model is best for heavy creators.
