Samsung Galaxy S25 Ultra and Galaxy S25: The Ultimate Verdict

Samsung has officially unveiled its latest flagship lineup, the Galaxy S25 Ultra and Galaxy S25, boasting cutting-edge AI integration, a powerhouse chipset, and refined design enhancements. With competition heating up from Apple’s iPhone 16 Pro Max and Google’s Pixel 9 Pro XL, does Samsung’s newest offering justify the hype? Let’s dive into the details.

Design & Display: Aesthetic Refinements with Brighter Screen

The Galaxy S25 Ultra maintains Samsung’s signature premium build but refines it further with a thinner, lighter frame and reduced bezels. The display has been slightly enlarged to 6.9 inches without increasing the phone’s overall size.

On the other hand, the Galaxy S25 sports a 6.7-inch Dynamic AMOLED 2X display with a 120Hz refresh rate, HDR10+ support, and a peak brightness of 2,600 nits, ensuring excellent visibility even under direct sunlight. However, competitors like the Pixel 9 Pro XL push brightness even further, leading some to feel Samsung lags slightly in this department.

Build Quality and Durability

• Both models feature Gorilla Glass Victus 2 for improved scratch resistance.
• IP68-rated water and dust resistance, making them highly durable.
• Armor Aluminum 2 frame, providing better drop protection​.

Performance & AI Features: A Leap into the Future?

Powered by Qualcomm’s Snapdragon 8 Elite for Galaxy, the S25 Ultra delivers a 36% boost in single-core and a 39% boost in multi-core performance compared to the S24 Ultra. This places it ahead of most competitors, even the iPhone 16 Pro Max, in raw multi-core performance.

AI-Powered Enhancements

Samsung is heavily investing in AI-driven features, including:

• "Circle to Search" and "AI Select" for intuitive information retrieval.
• Conversational AI with Gemini (Google’s AI), enhancing voice-assisted tasks.
• Cross-App Action, allowing seamless data sharing between Google and Samsung apps (e.g., integrating contacts, calendar, and maps in a single AI-powered query).

While these AI-driven features aim to enhance user experience, early reviews indicate inconsistencies in Gemini’s accuracy when handling more complex requests​.

Camera System: Incremental Upgrade or Game Changer?

Samsung has retained its 200MP primary sensor for the S25 Ultra, with improvements in low-light performance and better AI processing. However, some users may be disappointed as optical zoom has been reduced to 3x instead of the previous 5x.

Camera Specifications

• Galaxy S25 Ultra:
  • 200MP main sensor with f/1.8 aperture.
  • 12MP ultra-wide sensor.
  • 10MP telephoto with 3x zoom.
  • 8K video recording at 30fps​.
• Galaxy S25:
  • 50MP main sensor.
  • Ultra-wide and telephoto lens with OIS.
  • 4K video support.

Low-light performance has been refined, and AI-driven image processing enhances details and sharpness, making night photography more vibrant. However, some critics argue that Google’s Pixel 9 Pro still leads in computational photography​.

Battery Life & Charging: Samsung Plays It Safe

Battery life remains a strong suit for the S25 Ultra, clocking in at an impressive 34 hours and 34 minutes on moderate usage. However, Samsung has retained the 5,000mAh battery from its predecessor, without incorporating new silicon-carbon battery technology seen in some competitors.

Charging Details

• 45W wired charging (charges 50% in 19 minutes and 100% in under 50 minutes).
• 15W wireless charging.
• 4.5W reverse wireless charging (for charging accessories like Galaxy Buds).

Samsung’s charging speeds are still behind some rivals offering 100W+ fast charging, which may be a letdown for power users​.

Software & UI: One UI 7.0 with Android 15

The Galaxy S25 series ships with Android 15 and Samsung’s One UI 7.0, featuring:

• Improved multitasking capabilities with Samsung DeX.
• “Now Brief” and “Now Bar” for AI-driven daily summaries.
• More refined animations and smoother UI interactions.

While the UI is highly customizable, Samsung’s software still includes some bloatware, which may frustrate users who prefer a cleaner Android experience​.

Connectivity & Extras: The Future-Proofed Flagship

• Wi-Fi 7, 5G, Bluetooth 5.4, NFC.
• eSIM and Dual SIM support.
• Ultrasonic in-display fingerprint scanner.
• Stereo speakers with Dolby Atmos.

Samsung retains its S Pen support on the Ultra model, further improving latency for a smoother writing experience​.
