The Samsung Galaxy S25 Ultra is the larger, S Pen-equipped choice; the vivo X300 is the smaller phone with a higher listed battery capacity and faster charging claims. Their camera systems and regional prices also differ, but manufacturer specifications alone cannot establish which takes better photos or lasts longer in everyday use. The right choice depends on size, stylus needs, local price and the exact regional model.
Samsung Galaxy S25 Ultra vs vivo X300: key specifications
The figures below come from Samsung’s India product page and vivo’s global product page, so they are not necessarily identical to every regional version. Treat battery and charging figures as manufacturer specifications, not independent comparative test results.
| Specification | Samsung Galaxy S25 Ultra | vivo X300 |
|---|---|---|
| Display | 6.9-inch-class Dynamic AMOLED 2X; 3120 × 1440 resolution; up to 120 Hz | 6.31 inches; vivo promotes a ZEISS Master Color display and 120 Hz |
| Rear cameras | 200 MP + 50 MP + 50 MP + 10 MP; 3x and 5x optical zoom, with 2x and 10x optical-quality zoom listed | 200 MP main + 50 MP telephoto + 50 MP ultra-wide |
| Front camera | 12 MP, autofocus | 50 MP, autofocus |
| Battery and charging | 5000 mAh typical; Samsung lists up to 31 hours of video playback | 6040 mAh; vivo advertises up to 90 W wired and 40 W wireless charging |
| Stylus and productivity | S Pen support and Samsung DeX support | No equivalent built-in stylus feature established by the cited vivo pages |
| Water and dust resistance | Not stated in the cited comparison sources | vivo states IP68 and IP69, and cautions that resistance may reduce with wear |
| Security-update end date | Samsung’s India page lists security updates through 31 January 2032 | Comparable explicit end date not confirmed in the cited sources |

Which phone is better for your priorities?
Choose the S25 Ultra for a large screen and S Pen workflows
Samsung’s 6.9-inch-class display makes the S25 Ultra the larger option in this pairing. Its built-in S Pen support suits handwriting, annotation and sketching, while Samsung also lists DeX support. Those features are distinct practical advantages if you use a stylus or want Samsung’s desktop-style productivity mode.
#1 Best Overall
- Stunning 6.9″ Dynamic AMOLED 2X QHD+ display with adaptive 1–120 Hz refresh rate, ultra‑bright up to ~2600 nits, HDR support, “Vision Booster,” and adaptive color tone — giving vivid colours, great outdoor visibility, and super‑smooth scrolling.
- Powerful internals: it runs on the new Snapdragon 8 Elite for Galaxy (3 nm) chip, with 12 GB (or in some markets up to 16 GB) RAM and up to 1 TB UFS 4.0 storage — offering significantly improved CPU/GPU/NPU performance, especially for AI tasks, gaming, and heavy multitasking.
- Advanced quad‑camera system: 200 MP wide main sensor, plus a 50 MP ultrawide, a 50 MP periscope telephoto (5× optical zoom), and a 10 MP telephoto (3× optical zoom) — giving flexibility from ultra‑wide through detailed telephoto shots, and strong performance in varied lighting.
- 5,000 mAh battery with 45 W fast wired charging, wireless charging (Qi2) and reverse wireless charging — balancing long battery life with flexible charging options.
- Durable, premium build: Titanium‑frame body, protected by Corning Gorilla Armor 2 glass, with IP68 dust/water resistance, ultrasonic in‑display fingerprint sensor, modern connectivity (5G, Wi‑Fi 7, Bluetooth, UWB, USB‑C), and long‑term software support (Android 15 / One UI 7, promised 7 major OS/security updates).
Consider the X300 if you want the smaller phone
At 6.31 inches, the vivo X300 has the smaller listed display diagonal. That makes it the more compact choice on paper, though screen size alone does not determine the phone’s full dimensions or how comfortable it feels in your hand.
Compare camera systems by zoom needs, not megapixel totals
Samsung lists four rear cameras, including 3x and 5x optical zoom. vivo lists three rear cameras—a 200 MP main, 50 MP telephoto and 50 MP ultra-wide—and promotes a separate 2.35x telephoto extender. The configurations offer different ways to cover focal lengths, but the sensor counts and resolution figures do not prove which phone produces better photos. Independent side-by-side testing would be needed for that verdict.

Both manufacturers list autofocus for the front camera: Samsung specifies 12 MP and vivo 50 MP. Resolution alone does not establish portrait quality, skin rendering or low-light performance.
Read battery and charging claims in context
Samsung lists a typical 5000 mAh battery and up to 31 hours of video playback. vivo lists 6040 mAh and advertises charging up to 90 W wired and 40 W wireless. These are not equivalent measures: battery capacity and charging power do not predict real-world endurance, and the manufacturers’ figures do not constitute a shared independent test. Charging power can vary with use; charger inclusion also differs by region.

What is the price difference?
There is no reliable single current price difference without choosing a country, storage configuration, tax basis and date. The available vivo figures are regional launch-price references, not current prices for a like-for-like comparison with Samsung.
| Market and source | vivo X300 price reference | What it represents |
|---|---|---|
| Spain | €1,049 for 12 GB + 256 GB; €1,099 for 16 GB + 512 GB | Launch prices reported by Cinco Días / El País in 2025; not confirmed current retail prices. Source |
| China | CNY 4,599 for 12 GB + 256 GB | Configuration- and market-specific listing on vivo China; year was not confirmed in the captured result, so it is not a current worldwide price. Source |
| Samsung comparison price | Not stated | No comparable Samsung price for the same market and date was established in the cited sources. |
Do not subtract a Spain launch price from a China listing or compare either with a Samsung price from a different market or date. For a useful comparison, check listings in your country for the same storage tier and account for taxes and promotions consistently.

Regional details to check before buying
The specifications and support information above are market-specific. Samsung’s cited product page is for India; its security-update date should not be treated as a universal regional commitment without checking the local model information. vivo’s global page includes network-band information, but the exact model, available features and package contents can vary by market.

- Confirm the exact regional model and whether its network bands suit your carrier.
- Check eSIM support, warranty coverage and local availability for the specific variant; the cited pages do not establish these details for every country.
- Verify what is included in the box. vivo’s overseas package table says the charger is absent for Europe; charger availability can differ elsewhere.
- Compare the same memory and storage configuration, using local prices from the same date and the same tax basis.
- Check local support terms directly. Samsung’s India page lists a security-update endpoint of 31 January 2032; a comparable explicit vivo end date was not confirmed in the cited sources.
Verdict: pick by size, stylus use and local deal
The Galaxy S25 Ultra is the clearer fit if you want a large display, built-in S Pen support or Samsung DeX. The vivo X300 is the smaller-screen option and has the higher listed battery capacity and charging-power claims. The available evidence does not establish a universal winner for camera quality, battery life or value: compare current local prices for matching configurations, then weigh the features you will actually use.
