Performance & Software

Under the hood, the S25 Ultra is powered by a customized Snapdragon 8 Elite for Galaxy chip, coupled with 12 GB of RAM in its base model.Storage options include 256 GB, 512 GB, and 1 TB, giving users plenty of room for media and large apps.On software, it ships with Android 15 and One UI 7, which brings a host of new AI-driven features like “Now Brief,” improved widgets, and smarter multitasking.

Camera System: A Major Focus

One of the most talked-about aspects of the Samsung S25 Ultra is its camera setup. Leaks and early reports suggest a quad-lens system that includes:

  • A 200 MP primary sensor, likely delivering exceptional detail.

  • A 50 MP ultra-wide lens for wide-angle shots.

  • A 50 MP and a 10 MP telephoto lens, offering both mid-range and long-range optical zoom.

  • On the front, a 12 MP selfie camera provides solid performance for video calls and portraits.

Beyond raw resolution, the S25 Ultra is expected to leverage AI-powered image processing to boost low-light photography, apply generative edits, and give users more flexible creative tools.

Battery Life & Charging

Samsung has equipped the S25 Ultra with a 5,000 mAh battery, which many see as a balanced choice between performance and device thickness.The phone supports 45 W wired fast charging, along with wireless charging and reverse wireless power share—so you can juice up your buds or watch on the go.While not class-leading in charging speed, this setup is solid for daily use.

Durability, Connectivity & Extras

Durability gets a serious boost: the S25 Ultra uses Gorilla Armor 2, which, according to Samsung and Corning, offers significantly improved drop resistance.It also comes with IP68 rating for water and dust resistance.Connectivity is strong, with 5G, Wi-Fi, Bluetooth 5.4, and even Wi-Fi 7 support in some variants. 

Another feature that stands out is the built-in S Pen, though in this generation Samsung reportedly removed some Bluetooth-enabled S Pen functions, focusing more on writing, sketching, and precise input. 

Why the Samsung S25 Ultra Is a Big Deal

  • AI-first experience: With One UI 7 and new Galaxy AI tools (like “Now Brief” and generative features), Samsung leans heavily into on-device intelligence.

  • Photography power: A 200 MP sensor combined with smart AI processing means the S25 Ultra could be one of the top camera phones on the market.

  • Flagship performance: The Snapdragon 8 Elite for Galaxy promises high performance, especially for AI tasks and gaming.

  • Premium build: The titanium frame and tougher glass make it a luxury device that feels rugged yet refined.

  • Software longevity: Samsung’s commitment to long-term updates gives value to buyers who want to keep the phone for years.

Possible Downsides & Criticisms

Despite its strengths, the S25 Ultra is not without criticism:

  • The 5,000 mAh battery capacity, according to some users, is insufficient for a "Ultra" gadget. “Missing S Pen features … No 6000 mAh battery … charging speed feels slow”

  • The S Pen lacks Bluetooth functionality, which means you lose remote control features some might have loved in past Ultra models.

  • Charging still lags behind competitors: At 45 W wired charging, there are faster alternative devices on the market.

  • Some users worry about heating or stability issues, likely because of the powerful AI workload.

Final Thoughts

In summary, the Samsung S25 Ultra emerges as a true flagship in 2025. It combines premium build materials, seriously high-end camera capabilities, and cutting-edge AI features. For power users, creators, and tech enthusiasts who want a phone that can do it all, the S25 Ultra makes a compelling case. That said, its high price point, modest charging speeds, and the removal of certain S Pen features are things to weigh carefully.

If you’re someone who prioritizes performance, design, and long-term software support, the Samsung S25 Ultra could be one of the best choices available right now.
