Lifestyle and Tech had the opportunity to review this device for two weeks, and what follows is our unfiltered experience with Samsung’s latest flagship.
In a world where smartphones have become increasingly indistinguishable black rectangles, Samsung has managed to do something remarkable with the Galaxy S25 Ultra: they’ve made me care about a phone again. Not just as a tool, but as a companion that anticipates what I need before I even realize I need it.
The moment you power on the S25 Ultra, you realize this isn’t just another incremental update. Galaxy AI doesn’t merely exist on this device—it permeates every aspect of its experience. During my testing period, I found myself having natural conversations with my phone that actually accomplished things, from scheduling appointments to summarizing long email threads.
What’s particularly impressive is how the AI seems to learn your patterns and preferences, becoming more helpful the longer you use it. By the end of week one, it was suggesting smart replies that sounded eerily like something I would write. By week two, it was proactively offering to help with tasks based on my calendar and location.
The best part? These AI features are complimentary through 2025, giving users ample time to integrate these capabilities into their daily routines before potentially having to pay for them.
Samsung has finally embraced what many of us have been saying for years: ultra-premium phones should feel ultra-premium. The S25 Ultra’s titanium frame provides a substantial feel without unnecessary weight, while the rounded design marks a welcome departure from the sharp-edged aesthetic of recent models.
The built-in S Pen continues to be a differentiator in the crowded smartphone market, but now it feels more integrated into the overall experience rather than an afterthought. The titanium frame (which, I should note, is only applied to the device frame and not the volume or side keys) provides a sophisticated look that actually justifies the premium price point.
The new AI ProVisual Engine represents the biggest leap in smartphone photography I’ve seen in years. It’s not just about adding more megapixels or lenses—it’s about making the entire capture and editing process more intelligent.
During a challenging sunset shoot, the camera automatically adjusted settings I wouldn’t have thought to change, resulting in images with detail in both shadows and highlights that would normally require extensive post-processing. The optical zoom capabilities (true optical at 3x and 5x, with “optical quality” at 2x and 10x distances thanks to the Adaptive Pixel sensor) give you tremendous creative flexibility.
What truly sets this camera system apart, however, is how the editing tools seem to know what you want to do before you do it, suggesting adjustments that enhance rather than distract from your original vision.
Samsung’s decision to create a custom-made chipset specifically optimized for Galaxy devices pays dividends in real-world performance. Apps launch instantaneously, complex edits render in seconds, and gaming performance—particularly with titles that utilize real-time ray tracing—delivers a visual fidelity I previously associated only with dedicated gaming hardware.
The improvement over the S24 Ultra is immediately noticeable, especially during extended gaming sessions where thermal management becomes critical. The S25 Ultra maintains peak performance without the throttling issues that plagued previous generations.
Perhaps the most practical improvement comes in the form of battery life. Samsung’s pioneering mDNIe technology integrated into the custom processor, combined with intelligent software optimization, resulted in the S25 Ultra consistently lasting well into a second day of heavy usage during my testing.
Video playback, traditionally a battery killer, barely seemed to register in the battery statistics. While your mileage will certainly vary depending on settings, brightness, and network conditions, this represents a meaningful step forward in addressing one of the most common pain points in modern smartphones.
The new One UI 7 feels like the first interface truly designed around AI capabilities rather than simply accommodating them. The Now Bar provides instant access to alerts, music controls, and timers without unlocking your phone—a small change that significantly reduces friction throughout the day.
The customizable widgets allow for a level of personalization that feels substantial rather than cosmetic, though some functions do require network connectivity or Samsung Account login.
The Samsung Galaxy S25 Ultra isn’t perfect—no device is—but it represents the most compelling vision yet of where smartphones are headed. By focusing on meaningful AI integration rather than gimmicks, Samsung has created a device that actually enhances productivity and creativity in tangible ways.
At its premium price point, the S25 Ultra isn’t for everyone. But for those seeking the absolute cutting edge of what’s possible in a smartphone in 2025, Samsung has set a new standard that competitors will struggle to match.
