If you’re shopping for a premium smartphone in 2025, two top contenders stand out: the Apple iPhone 16 and the Samsung Galaxy S25 Ultra. Both pack flagship performance, cutting-edge cameras, long software support, and hefty price tags. But despite their similarities, each takes a different approach. This detailed comparison will help you decide which is the right pick for you—covering design, display, camera, performance, software, battery & charging, value and final verdict.
Design & Build
iPhone 16 uses an aluminium frame, Ceramic Shield front and colour-infused glass back. Its dimensions: 147.6 mm height, 71.6 mm width, 7.8 mm thickness, and 170 g weight. With familiar flat edges and new colour options (Black, White, Pink, Teal, Ultramarine) it maintains Apple’s signature styling.
Galaxy S25 Ultra upgrades to a titanium frame (in some markets) and Gorilla Armor 2 glass, reducing fragility. The weight: ~218 g and thickness ~8.2 mm. While slightly heavier, the Ultra offers premium materials and a larger footprint.
Winner: Apple for lighter, narrower form-factor; Samsung for premium materials and larger display asset.
Display
iPhone 16: 6.1-inch Super Retina XDR display, OLED, 2556×1179 resolution, contrast ratio ~2,000,000:1.
Galaxy S25 Ultra: 6.9-inch Dynamic AMOLED 2X, QHD+ (~3120×1440), 120Hz refresh, peak brightness up to 2600nits.
Samsung clearly leads in size, refresh rate and resolution—ideal for media, gaming and multitasking. If you prefer compact, the iPhone wins.

Samsung S25 Ultra uses Snapdragon 8 Elite (or equivalent regional), up to 16GB RAM + up to 1TB storage. Runs Android 15 + One UI 7 with Galaxy AI features built-in.
Both deliver exceptional performance; Apple tends to get longer update support, Samsung offers more hardware flexibility and features.
Winner: Tie—choose based on ecosystem preference.

Samsung S25 Ultra: 5000mAh battery + improved cooling and 45W wired/25W wireless charging.

Winner: Samsung for raw battery and charging; Apple for daily reliability.
Ecosystem & Features
Apple ecosystem: tight integration (AirPods, iPad, Mac), industry-leading app support, resale value.
Samsung ecosystem: broader hardware diversity (S-Pen support on Ultra, foldables, SmartThings), expandable storage and hardware features. Ultra also emphasises AI features and future-proofing.
If you’re invested in either ecosystem, stick accordingly.
Winner: Depends on ecosystem preference.
Value & Price
iPhone 16 commands premium price; entry storage size may be higher cost than previous years.
Samsung S25 Ultra is similarly premium, but often offers more storage/hardware for the price. According to reviews, S25 Ultra remains a top Android option but doesn’t move much from S24 generation improvements—affecting the value calculus.
For value-conscious buyers: choose whichever deals better in your region, and consider storage/upgrades carefully.
Winner: Slight edge to Samsung for hardware vs cost.
Which One Should You Buy?
- Pick iPhone 16 if you: prefer compact size, seamless Apple integration, best video recording, longer software support, simpler experience.
- Pick Galaxy S25 Ultra if you: want the largest display, best camera hardware, S-Pen functionality, Android flexibility, and best zoom/AI features.
- Budget tip: Compare current pricing, consider previous generation discounts (iPhone 16 Pro, S24 Ultra) if value matters more than bleeding-edge specs.
Final Verdict
Both are top‐tier flagship smartphones in 2025. Neither choice is “wrong”. The decision hinges more on ecosystem, form-factor preference, and feature priorities.
If you’re upgrading from an older phone (3+ years) both will feel like major leaps. But if you already own something recent, ask: “Will this upgrade make a big tangible difference for my daily use?”
