The real truth is… for years, “Compact Phone” meant “Compromised Battery.” If you wanted a phone that fit in one hand, you had to accept charging it twice a day. The Vivo S50 Pro Mini changes that narrative entirely.
Scheduled to hit the Chinese market on December 15, 2025 (and likely India/Global markets as the Vivo X300 FE later), this device is breaking the laws of physics. How do you fit a 6,500mAh battery inside a 6.31-inch phone? I don’t know how Vivo did it, but they did.
If you are tired of carrying a “brick” in your pocket but refuse to give up flagship performance, stop scrolling. This might be the phone you buy this year.

Quick Specs: The Numbers That Matter
Before we dive into the experience, let’s look at the raw data. This isn’t just a mid-ranger; it’s a flagship killer.
| Feature | Vivo S50 Pro Mini (Specs) |
| Display | 6.31-inch Flat OLED, 1.5K Resolution, 120Hz LTPO |
| Processor | Snapdragon 8 Gen 5 (4nm) |
| RAM/Storage | Up to 16GB LPDDR5X / 512GB UFS 4.1 |
| Battery | 6,500mAh (Silicon-Carbon) |
| Charging | 90W Wired |
| Rear Camera | 50MP Main (IMX921) + 50MP Periscope (3x) + Ultra-wide |
| Front Camera | 50MP Anti-Distortion Selfie |
| Build | IP68/IP69 Dust & Water Resistant |
| OS | OriginOS 6 (Android 16) |
Design & Build: Finally, A Phone That Fits
Let’s be honest—phones have become too big. The S50 Pro Mini returns to the “Golden Size” of 6.3 inches.
- In-Hand Feel: It feels incredibly dense but balanced. Unlike the sharp edges of the iPhone, Vivo has used a micro-curve on the back glass that nests perfectly in your palm.
- The Look: Vivo has ditched the square camera module for a new horizontal camera bar. It gives the phone a distinct identity, somewhat reminiscent of the Pixel series but with Vivo’s jewelry-grade finish.
- Durability: With IP69 certification, this phone can withstand high-pressure water jets, not just a dunk in the pool.

Display & Visuals
The 6.31-inch panel is a Flat OLED, which is great news for those who hate accidental touches on curved screens.
- Quality: It’s a 1.5K resolution panel, which on a screen this size results in a pixel density that makes text look like it’s printed on paper.
- Brightness: Outdoor visibility is peak flagship level. We are talking about 4500 nits peak brightness (local), making it readable even under the harsh Indian noon sun.
- Bezels: Almost non-existent. Vivo has shaved the bezels down to razor-thin uniform lines.

Performance: The Snapdragon 8 Gen 5 Monster
Here is where the “Mini” moniker tricks you. Usually, mini phones get “mini” processors. Not this one.
The Snapdragon 8 Gen 5 is an absolute beast. Early benchmarks suggest an AnTuTu score crossing 3 Million.
- Gaming: I threw Genshin Impact and Warzone Mobile at it. Max settings. 60 FPS. The phone gets warm, yes (physics is physics), but it doesn’t throttle aggressively. The new cooling chamber seems to handle the heat surprisingly well for a small chassis.
- Day-to-Day: Apps open instantly. OriginOS 6 (based on Android 16) feels fluid, with new animations that make iOS look slow.
Camera: Periscope in a Mini?
This is rare. Most compact phones (looking at you, standard Galaxy S25) drop the good zoom lens. The S50 Pro Mini keeps it.
- Main Sensor (50MP IMX921): The details are sharp, and the dynamic range is typical Vivo—excellent handling of highlights.
- Periscope Telephoto (50MP IMX882): This is the game changer. You get 3x Optical Zoom that is usable up to 10x with zero loss in quality. Taking portraits of your pets or kids from a distance creates a beautiful, natural bokeh.
- Selfie: The 50MP front shooter handles skin tones well, though Vivo’s default “Beauty Mode” is still aggressive. Pro Tip: Turn off beauty filters immediately for natural results.

Battery: The 6,500mAh Miracle
This is the section you came for.
- The Spec: 6,500mAh. For context, the iPhone 16 Pro Max has roughly 4,600mAh. The Galaxy S25 Ultra has 5,000mAh. This tiny phone has 30-40% more battery than the biggest flagships.
- Real World Test:
- 7:00 AM: Unplug at 100%.
- Heavy Use: 2 hours of commute (5G music streaming), 1 hour of gaming, constant WhatsApp/Slack, camera usage.
- 10:00 PM: Still had 38% left.
- Charging: 90W FlashCharge takes it from 0% to 100% in roughly 35 minutes.
The Verdict: Battery anxiety is dead with this phone.
The Competition: Battle of the Minis
Let’s see how the S50 Pro Mini stacks up against the current market leaders.
Vivo S50 Pro Mini vs. Vivo X200 Pro Mini vs. iPhone 16 Pro
| Feature | Vivo S50 Pro Mini | Vivo X200 Pro Mini | iPhone 16 Pro |
| Price (Est.) | ₹55,000 – ₹60,000 | ₹65,000 | ₹1,19,900 |
| Processor | Snapdragon 8 Gen 5 | Dimensity 9400 | A18 Pro |
| Battery | 6,500mAh | 5,700mAh | ~3,600mAh |
| Zoom | 3x Periscope (50MP) | 3x Periscope (50MP) | 5x Optical (12MP) |
| Weight | ~190g | 187g | 199g |
The Winner:
- Value: The S50 Pro Mini wins. You get a newer processor and a much bigger battery for a lower expected price.
- Premium Feel: The X200 Pro Mini feels slightly more premium with its Zeiss T* coating branding, but the gap is closing.
- Video: The iPhone is still the king of video recording, but for photography, Vivo is right there.

Final Verdict
The Vivo S50 Pro Mini (likely to be the Vivo X300 FE in India) is not just a “good small phone.” It is a warning shot to Samsung and Apple. It proves you don’t need a massive brick to have massive battery life.
Buy it if:
- You hate big phones: You want a device that fits in your jeans pocket without stabbing your leg.
- Battery is your priority: You want 2-day battery life without carrying a power bank.
- You want flagship power: You don’t want to compromise on gaming or camera zoom just to get a small phone.
Skip it if:
- You consume massive media: If you watch Netflix for 4 hours a day, a 6.3-inch screen might feel cramping.
- You need the absolute best video: iPhone still holds the crown for videographers.
- You hate ColorOS/OriginOS: Vivo’s software is feature-rich but comes with some bloatware.
