Vivo S50 Pro Mini: Compact Flagship Design & Key Specs Revealed
The era of compact flagships is officially back — and Vivo clearly wants to lead the wave. The upcoming Vivo S50 Pro Mini is shaping up to be one of the most interesting phones of late 2025: small in size, huge in power, and designed to compete with ultra-slim devices like the iPhone Air.
Vivo has already revealed the phone’s design and key specifications through official teasers and product manager posts, so this isn’t just rumor territory anymore. Even better, for markets like India and global regions, the same phone is widely expected to launch under a different name: Vivo X300 FE. Moneycontrol+1
In this blog, we’ll break down everything you need to know about the S50 Pro Mini — in a simple, human way — including its:
…and finally, whether it’s a phone worth watching if you love compact but powerful devices.
What Is the Vivo S50 Pro Mini, Exactly?
The Vivo S50 Pro Mini is part of the upcoming Vivo S50 series in China, which will include the standard Vivo S50 and this compact “Pro Mini” variant. It’s positioned as a “compact flagship” — meaning you get high-end specs in a smaller, more pocket-friendly body, instead of the huge slabs that most flagships have become. Moneycontrol+1
Globally, especially in India, this same phone is expected to arrive as the Vivo X300 FE, just like how the older Vivo S30 Pro Mini became the Vivo X200 FE outside China. Moneycontrol+1
So if you later see “X300 FE” trending — that’s basically the S50 Pro Mini in disguise.
Design: Mini Size, Premium Feel
Clean, Flat, Modern Look
From official images and teasers, the Vivo S50 Pro Mini:
-
Uses a flat frame with a sleek, slim profile
-
Has a horizontal camera bar stretching across the back — similar in spirit to the iPhone Air and some Honor phones, but with Vivo’s own twist 91mobiles+1
-
Comes in at least one very eye-catching color: “Inspiration Purple”, a soft lavender-like shade 91mobiles
This camera bar design makes it stand out immediately from most phones that still use vertical camera stacks.
Premium Materials
Vivo isn’t cutting corners on build quality either:
-
Aerospace-grade aluminium frame for a sturdy, premium feel 91mobiles+1
-
A back panel made using a special “satin lithography” process, meant to give it a soft, matte, comfortable texture in hand Beebom Gadgets+1
This is the kind of finish you typically see only on premium flagships, not on “Lite” or “Mini” branded phones.
IP68 + IP69: Serious Protection
One of the biggest surprises is that the S50 Pro Mini is confirmed to have both:
Put simply: this is not a fragile toy. Vivo clearly expects people to use this as a daily driver without being scared of rain, splashes, or dust.
Display: Smallish Size, Big Quality
If you miss compact phones, this is where the S50 Pro Mini really shines.
-
Size: 6.31-inch flat OLED / AMOLED display
-
Resolution: Around 1.5K (1216 × 2640) – sharper than standard Full HD+ Beebom Gadgets+1
-
Refresh Rate: 120 Hz for smooth scrolling and gaming Beebom Gadgets+1
-
Extras: High PWM dimming and an in-display fingerprint reader
Because the screen is “only” 6.31 inches and flat, the phone will feel noticeably more compact and manageable than 6.7–6.9" curved flagship phones that dominate the market today.
It’s also confirmed to feature Vivo’s 2nd-gen 3D ultrasonic in-display fingerprint sensor, which should be faster and more accurate than optical readers. Beebom Gadgets+1
Performance: Snapdragon 8 Gen 5 Power
Under the hood, the Vivo S50 Pro Mini is not playing around.
-
Chipset: Qualcomm Snapdragon 8 Gen 5 – Qualcomm’s top-tier flagship SoC Moneycontrol+1
-
RAM: LPDDR5X RAM (fast, flagship-grade)
-
Storage: UFS 4.1 (very fast read/write speeds) Moneycontrol+1
Vivo’s own product manager has claimed that the S50 Pro Mini scores over 3 million points on AnTuTu, which puts it squarely in ultra-flagship territory. Moneycontrol+1
For real-world use, that means:
-
No issues with heavy multitasking
-
High-end gaming at max or near-max settings
-
Smooth performance for years, not just months
Again, this is in a compact chassis, which is rare — most compact phones compromise on power; this one doesn’t.
Cameras: Triple Rear Setup With Periscope Zoom
Camera lovers have a lot to be excited about here.
Based on current teasers and leaks, the S50 Pro Mini is expected to have: India Today+1
-
Main camera: 50 MP Sony IMX921 (high-quality, large sensor)
-
Telephoto: 50 MP Sony IMX882 periscope telephoto with 3x optical zoom
-
Ultra-wide: Additional ultra-wide camera for landscapes and group shots
-
Front camera: 50 MP selfie shooter
That periscope telephoto lens is a big deal. You usually only see periscope zoom on full-size flagships and ultra phones. Here, Vivo is putting it on a compact device, making the S50 Pro Mini especially attractive for travel photography, portrait shots, and zoomed-in detail.
If Vivo’s usual image processing and stabilization carry over from its X-series flagships, we can expect:
Battery & Charging: Compact But Endurance Monster
Here’s another spec that doesn’t feel “Mini” at all:
-
Battery capacity: 6,500 mAh
-
Wired charging: 90W fast charging
-
Wireless charging: 40W fast wireless Moneycontrol+1
A 6,500 mAh battery in a compact flagship is wild. Most regular flagships struggle to fit 5,000 mAh, especially when they’re slim. Vivo somehow combines:
On paper, this phone should easily last a full day of heavy use, possibly even into a second day for moderate users — and charge up quickly when needed.
Other Key Features
A few more things that round out the S50 Pro Mini experience:
-
Stereo speakers for better media consumption and gaming 91mobiles+1
-
Android 15 (expected) with Vivo’s custom skin on top
-
Likely 5G support, Wi-Fi 7, Bluetooth 5.x (based on typical Snapdragon 8 Gen 5 setups, though details are not fully confirmed yet)
All this makes the phone feel less like a “Mini edition” and more like a full flagship in a smaller shell.
Expected Launch & Naming: S50 Pro Mini vs X300 FE
Here’s what current info suggests:
-
The Vivo S50 Pro Mini will launch first in China as part of the S50 series in December 2025. My Mobile India+1
-
For global markets like India, Europe, etc., it is widely expected to launch later as the Vivo X300 FE. Moneycontrol+1
Pricing is still unknown, but as a rough reference, the previous X200 FE launched in India at around ₹54,999. India Today+1
Given the upgraded chipset, bigger battery, periscope zoom and premium build, the X300 FE / S50 Pro Mini could be in a similar or slightly higher price range — likely a upper-mid to flagship-tier price bracket.
Who Is the Vivo S50 Pro Mini For?
This phone seems tailor-made for you if:
-
You hate huge phones but still want flagship power
-
You care about camera quality, especially zoom and portraits
-
You love premium materials and design (metal frame, unique color, satin back)
-
You want strong battery life without carrying a power bank everywhere
-
You appreciate details like IP68/IP69 ratings and ultrasonic fingerprint scanners
On the other hand, it might not be for you if:
-
You prefer very large screens (6.7"+) for media
-
You’re on a tight budget — compact flagships are rarely “cheap”
-
You’re not interested in camera and performance and just want a basic phone
Should You Wait for the Vivo S50 Pro Mini / X300 FE?
If you’re planning to upgrade in 2025 and:
-
You want a compact flagship
-
You care about battery and cameras
-
You don’t mind paying a premium, but not ultra-premium price
…then yes, this is definitely a phone worth waiting to see reviews for.
However, because this is still pre-launch:
-
Real-world camera samples, thermals, and battery life tests are still pending.
-
Actual global pricing and availability could change your decision.
So, the best move right now is:
-
Shortlist it if you like compact + powerful phones.
-
Wait for official launch + early reviews.
-
Compare it with alternatives from Samsung, Google, or Apple in the same budget.
Final Thoughts: A “Mini” That Doesn’t Think Small
The Vivo S50 Pro Mini is one of those rare devices that seem to tick all the boxes on paper:
-
Compact 6.31" AMOLED display
-
Snapdragon 8 Gen 5 power
-
Massive 6,500 mAh battery with 90W + 40W charging
-
50 MP main + 50 MP periscope telephoto + ultra-wide
-
50 MP selfie camera
-
IP68 + IP69, premium materials, modern design
It’s basically a no-compromise compact flagship, something many users have been asking for as phones keep getting larger and heavier.
If Vivo gets the pricing and optimization right, the S50 Pro Mini (or Vivo X300 FE globally) could become one of the most popular choices for people who want a phone that fits their hand — but doesn’t cut corners on performance or features.
