Samsung Galaxy S25 Ultra vs Xiaomi 17 at a glance
| Category | Samsung Galaxy S25 Ultra | Xiaomi 17 | What it means |
|---|---|---|---|
| Size and weight | 6.9-inch display measured across the full rectangle; 77.6 × 162.8 × 8.2 mm; 218 g | 6.3-inch display; 71.8 mm wide; 8.06 mm thick; 191 g | The Xiaomi is narrower and lighter on the published figures. Display measurement conventions may differ. |
| Display | QHD+ Dynamic AMOLED 2X, adaptive 1–120Hz | OLED, 2656 × 1220, adaptive 1–120Hz, 12-bit; Xiaomi claims up to 3500 nits multi-scenario peak brightness | Samsung offers the larger screen. Maker brightness claims are not a cross-lab comparison. |
| Rear cameras | 200MP wide, 50MP ultrawide, 50MP 5x telephoto, and 10MP 3x telephoto; OIS noted for main and telephoto cameras | Three 50MP Leica-branded cameras: 17mm ultrawide, 23mm main with OIS, and 60mm floating telephoto; Xiaomi describes 5x zoom as “optical-level” | Samsung specifies separate 3x and 5x telephoto modules. Xiaomi’s “optical-level” wording should not be treated as identical to Samsung’s optical-camera descriptions. |
| Front camera | 12MP | 50MP | Megapixel counts alone do not establish selfie quality. |
| Battery and charging | 5,000mAh typical capacity; Samsung’s US launch material says up to 65% in around 30 minutes with a 45W adapter and USB-C cable | 6,330mAh typical capacity; 100W wired and 50W wireless charging claimed | Xiaomi publishes higher capacity and charging rates. These specifications do not prove longer real-world battery life. |
| Platform at announcement | Qualcomm Snapdragon 8 Elite for Galaxy (regional Samsung material may use different wording); Android 15 / One UI 7 | Snapdragon 8 Elite Gen 5; HyperOS 3 on Xiaomi’s product page | Chip naming and software versions do not substitute for comparable benchmark testing; features and versions can change. |
| Memory and storage | 12GB RAM; 256GB, 512GB, or 1TB options; Samsung says memory options vary by market | Xiaomi’s cited global page does not clearly show a complete global storage matrix; regional specifications show 12GB + 512GB | Confirm the exact regional model before comparing prices or compatibility. |
| Water and dust resistance | IP68; Samsung describes lab submersion in up to 1.5m of freshwater for up to 30 minutes | IP68; Xiaomi describes lab conditions in up to 4m of static freshwater for up to 30 minutes | The different maker-described lab conditions do not show that one phone is more waterproof. Both warn that resistance is not unconditional or permanent. |
| Distinctive extras | Integrated S Pen; Wi-Fi 7 and Bluetooth 5.4 listed | Wi-Fi 7 readiness and Bluetooth 6.0 listed; regional support may vary | The S Pen may matter for handwriting, markup, and other stylus workflows. Connectivity depends on the local model and network equipment. |
Which phone is better for your priorities?
Choose the Xiaomi 17 for compact handling and charging specifications
At 191g and 71.8mm wide, the Xiaomi 17 is the smaller, lighter option on the published dimensions. Its 6,330mAh typical battery capacity and claimed 100W wired / 50W wireless charging rates are also higher than the S25 Ultra’s stated capacity and charging figures. Those are specification differences, not evidence of longer runtime or a faster charge in every real-world setup.

Choose the Galaxy S25 Ultra for a large screen, dedicated zoom cameras, or the S Pen
The S25 Ultra’s 6.9-inch display gives it a substantially larger viewing area than the Xiaomi 17’s 6.3-inch screen. Its camera specifications list separate 3x and 5x telephoto modules, and it includes an integrated S Pen. These features make it the more directly suited option if you specifically want a large display, those stated zoom steps, or stylus-based note-taking and markup.
Do not choose on megapixels or chip names alone
The Xiaomi’s front camera has more listed megapixels, while Samsung’s main rear camera has a higher listed megapixel count. Neither figure by itself establishes which phone takes better photographs. Likewise, the processors’ names and generations do not reveal comparative speed, heat, or sustained performance. The cited manufacturer specifications do not provide a controlled head-to-head camera, battery, or benchmark test.

- 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).
What is the price difference?
The available figures are launch references from different markets and dates, not current prices or a direct comparison. Samsung announced a US starting price of $1,299.99 for the 256GB Galaxy S25 Ultra in January 2025. Xiaomi Corporation disclosed a global Xiaomi 17 launch starting price of EUR 999 for its February 2026 global event. Different currencies, markets, launch dates, and potentially storage configurations mean these figures cannot be subtracted to produce a meaningful price difference.
To compare what you would pay, choose your country and compare current listings for the same storage capacity. Samsung says memory configurations vary by market; Xiaomi says product models and sale dates can vary by region. Verify the exact SKU, storage, warranty, network bands, software features, and local seller terms before buying.

Battery, charging, and durability: how to read the specifications
Capacity and charging rates are not runtime tests
Samsung lists a 5,000mAh typical battery, while Xiaomi lists 6,330mAh typical capacity and charging rates of 100W wired and 50W wireless. Xiaomi also publishes its internal-lab figures of 29.2 hours of video playback and at least 80% battery health after 1,600 charging cycles. Those are Xiaomi-reported results, with outcomes that can vary; they are not comparable tests against the Samsung phone. Samsung’s US launch material says the S25 Ultra can reach up to 65% in around 30 minutes using a 45W adapter and USB-C cable. Charger availability and charging conditions matter, so check what is included with the local SKU; Xiaomi says to confirm adapter inclusion with the seller and that wireless chargers are sold separately.

IP68 does not mean risk-free immersion
Both manufacturers list IP68 resistance and describe specific laboratory freshwater conditions, but the stated depths differ. Those descriptions do not establish a comparative waterproof ranking or guarantee protection in ordinary use. Samsung and Xiaomi caution that resistance can diminish or should not be treated as normal-use assurance.

What to verify before buying
- Match the storage capacity and regional model when comparing current prices.
- Check network-band compatibility, warranty coverage, and whether the software features you need are available in your market.
- Confirm the box contents with the local seller, especially the charging adapter; Xiaomi says wireless chargers are sold separately.
- Look for independent, controlled reviews if battery endurance, camera results, or sustained performance will decide your purchase. Manufacturer specifications alone cannot settle those comparisons.
