Samsung Galaxy S25 Ultra Review: 30-Day Upgrade Verdict

Design Evolution and Display Excellence

The Samsung Galaxy S25 Ultra introduces subtle but impactful design refinements over its predecessor. The most noticeable change is the rounded corners, departing from the sharper edges of previous Ultra models. This ergonomic shift makes the device more comfortable to hold despite its large form factor. At 15g lighter than the S24 Ultra, the weight reduction is immediately appreciable during extended use.

Visually, the camera housing now mirrors the aesthetic of Samsung's Z Fold 6, creating design consistency across flagship devices. The matte-finish Crocs official case (shown in the review) provides premium grip without adding bulk.

Display and Durability

Samsung retains last year's brilliant 6.8-inch Dynamic AMOLED display but upgrades protection to Corning Gorilla Glass Armor 2 – currently exclusive to the Ultra model. The anti-reflective coating significantly improves outdoor visibility. During testing in San Francisco and Japan, sunlight readability outperformed competitors like the iPhone 16 Pro Max. As reviewer Mary confirms: "It's less obvious meaning especially outdoors less distracting."

Camera System: Major Upgrades Tested

Hardware Improvements

The S25 Ultra's camera array features substantial hardware changes:

• New 50MP ultra-wide sensor capturing 36% more light
• 200MP main sensor with enhanced pixel-binning
• Dedicated 50MP 5x telephoto lens replacing last year's 10MP
• 12MP front-facing camera with improved low-light processing

Notably, the ultra-wide now doubles as a macro lens, capturing intricate details at 3cm distance. Mary's comparison shots reveal Samsung's signature vibrant processing: "Blue sky bluer than usual, green leaves deeper." While ideal for social media, photography purists may prefer Apple's neutral color science.

Video Capabilities Breakthrough

The standout feature is 8K log video recording – a smartphone first. This flat color profile preserves dynamic range for professional grading. Test footage shot in noisy environments retained clear vocals using the AI Audio Eraser tool (exclusive to Ultra models). As demonstrated in the burger shop sample, background chatter disappeared while foreground voices remained crisp.

Performance and AI Ecosystem

Powered by the Snapdragon 8 Elite chipset and 12GB RAM, the S25 Ultra handled intensive editing in Lightroom while running multiple apps. Gaming performance exceeded the iPhone 16 Pro Max in frame rate tests. Battery life matches the S24 Ultra despite the brighter display, lasting 6-7 hours screen-on time under mixed usage.

Transformative AI Features

• Gemini Integration: Replaces Bixby when long-pressing power button. Performs contextual actions like adding calendar events from conversations
• Now Brief: Exclusive summary tool compiling device activity. Shows full potential only with Samsung ecosystem products (Galaxy Watch/Ring)
• Search Bar AI: Processes natural language commands like "Make screen brighter" instead of menu navigation

The S Pen Compromise

Samsung removed Bluetooth functionality from the included S Pen, eliminating camera remote and gesture controls. Their justification: "Only 1% of users utilized these features." For Mary, who primarily uses the stylus for note-taking and document signing, this wasn't a deal-breaker. However, creatives who relied on remote shutter functionality should consider this downgrade.

Upgrade Decision Guide

Who Should Upgrade

• S22 Ultra owners: Significant camera, display and performance jumps
• Content creators: 8K log video and AI audio tools are game-changers
• Samsung ecosystem users: Now Brief becomes genuinely useful with multiple devices

Who Should Wait

• S24 Ultra users: Marginal improvements except for videography
• S Pen power users: Bluetooth removal may disrupt workflows
• Battery-focused buyers: Identical 5,000mAh capacity as previous model

Pro Tip: Trade-in programs offer up to $600 credit – offsetting the $1,299 base price.

Final Verdict

After 30 days of testing, the S25 Ultra's refinements coalesce into Samsung's most polished flagship. The camera system delivers tangible upgrades, particularly for videographers and travel photographers. While the removed S Pen features and unchanged battery capacity disappoint, the display technology and exclusive AI tools justify upgrading from devices older than two years. As Mary concludes: "It's the super smooth performance and really great display that made me appreciate this device every day."

Action Checklist

1. Test camera saturation preferences in Pro mode before important shoots
2. Activate video stabilization for handheld 8K recording
3. Enable "Adaptive touch sensitivity" when using the S Pen with screen protectors
