The refinement flagship — every detail sharpened, every weak spot addressed. But is incremental excellence enough?
First Impressions
You know that feeling when you walk into a shop, pick up the latest flagship, and think — “yep, looks exactly like last year’s.” That was the initial reaction many reviewers had with the S25 Ultra. But that first impression is deceptive. Samsung didn’t reinvent the wheel in 2025; it made the wheel significantly rounder.
The design is refined rather than reimagined. Gone are the sharp, angular corners of the S24 Ultra — the S25 Ultra adopts rounded edges that better align with Samsung’s broader Galaxy S design language. The titanium frame remains, the Gorilla Armor 2 glass stays, and at 8.2mm thin and 218g, it feels premium but purposeful in hand.
“This is still one of the best phones you can buy in 2025. But after three months of use, the S25 Ultra is less about mind-blowing innovation and more about small, smart refinements.”
Performance: Absolutely Flies
Under the hood, the Snapdragon 8 Elite chip — a custom “for Galaxy” variant — is the engine powering everything. Apps open instantly. Animations feel snappy. Gaming is flawless. The phone absolutely flies, and — crucially — it stays fast. Samsung also redesigned the vapor chamber, making it 40% larger with additional material layers, which is a quiet but significant upgrade for sustained performance and thermal management during heavy workloads.
Connectivity is another area where the S25 Ultra quietly impresses. In real-world testing, it consistently holds on to weaker cellular signals better than competing flagships, and switches between Wi-Fi and cellular faster — meaning fewer dropped connections when leaving the house.
The Camera System
The camera setup keeps the proven S24 Ultra formula but upgrades the ultrawide lens to a new 50MP sensor — a meaningful bump over the previous generation. The quad-camera array includes the flagship 200MP main sensor, the new 50MP ultrawide, a 10MP telephoto, and a 50MP periscope telephoto for extreme zoom.
- Daylight photography — sharp, well-exposed, and vibrant without tipping into overprocessed territory
- Low-light shots — holds detail without drowning in noise; the ProVisual Engine works quietly in the background
- Autofocus — quick enough to nail moving subjects like kids or pets in chaotic conditions
- Video — excellent across the board; Samsung has narrowed the gap to iPhone so much that for most users, it’s essentially a tie
- Galaxy AI photo tools — generative editing to remove, replace, or reframe objects; Drawing Assist lets you sketch and generate AI images with the S Pen
Galaxy AI: Useful or Overkill?
Galaxy AI is Samsung’s headline feature story for the S25 series, and the Ultra benefits from the full suite. Real-time call translation, meeting transcript summaries, a personalized “Now Brief” of your daily schedule, Audio Eraser for cleaning up video, and generative photo editing are all on board. One UI 7 also brings voice-enabled settings search — speak what you’re looking for and the phone finds it.
The honest verdict? When Galaxy AI works, it’s genuinely brilliant. But it can still feel like unnecessary fluff in everyday use. Samsung is clearly betting big on AI becoming the primary reason to upgrade, and the S25 Ultra is the best showcase of that bet — for better or worse.
“When it works, it works great. But a lot of times, it can feel like unnecessary AI fluff. The features that genuinely save time are outnumbered by those that require you to remember they exist.”
Battery & Charging
The 5,000mAh battery matches the S24 Ultra’s capacity, yet the S25 Ultra extends video playback to 31 hours — one hour longer than its predecessor, and the longest of any Ultra in the Galaxy S lineage. Brightness hits a stunning 2,600 nits peak on the Dynamic AMOLED 2X display. Charging is 45W wired and Qi2 wireless, which remains a sore point compared to the 65–80W speeds offered by OnePlus and Xiaomi at the same tier.
The S Pen — One Step Back
The built-in S Pen is still one of the S25 Ultra’s most defining features, and Samsung has deepened its AI integration with Drawing Assist. However, Samsung quietly removed Bluetooth from the stylus — a feature present since the Galaxy Note 9 in 2018. This means no more remote shutter for selfies and no gesture-based navigation controls. A cost-cutting measure or a usage-data decision, the Bluetooth removal upset a dedicated subset of Note and Ultra loyalists.
S25 Ultra Pros & Cons
Final Verdict
The Galaxy S25 Ultra is the best Android phone of 2025 — a masterclass in refining a proven formula to near-perfection. If you’re upgrading from an S22 Ultra or earlier, it’s a no-brainer. Owners of the S24 Ultra may find the incremental upgrades hard to justify. But for those looking for the most capable, future-proofed Android flagship money can buy, the S25 Ultra is the definitive answer..
