Do you usually pick a phone for its camera, its raw horsepower, or a clean, reliable software experience? With the Vivo X300, you don’t really have to choose. This compact flagship tries to nail all three, and surprisingly, it gets pretty close.
I’ve been using it as my main phone for the past week, and that’s been enough to understand where it shines, where it slips a little, and what it actually feels like to use every day. The overall experience turned out to be more impressive than I expected, largely because of the hardware Vivo has packed in at a starting price of ₹75,999. It’s a small phone, but definitely not a lightweight in what it delivers.
What caught my attention first wasn’t the camera; that crown belonged to last year’s X200. This time, it was the design. Vivo has shifted to a cleaner, more minimal look, and the frosted glass back lands in that sweet spot where it resists smudges without losing its premium feel. The unibody 3D glass design helps too, giving the phone a smoother, more cohesive look. I still gravitate toward the Elite Black variant, but the Mist Blue finish adds a softer, calmer vibe for anyone who prefers something understated.
The camera module also feels far more polished. The X200’s bump was noticeably chunky and made the phone wobble on tables; the X300 still has a bump, but it blends seamlessly and keeps the phone steady on flat surfaces.
The essentials are neatly placed along the flat aluminium frame, which curves slightly at the corners for a more comfortable grip. You get the power button and volume keys on the right, plus a dual-SIM tray and USB-C 3.2 port at the bottom. Stereo speakers round out the basics.
The biggest highlight, though, is the size. At roughly 190 grams and about 7.9mm thick for the Elite Black model, the X300 feels compact in a world where flagships keep getting bulkier. With both IP68 and IP69 protection, it’s a device that’s genuinely easy to use and carry every day.
Turn on the display and the X300 keeps the momentum going. It packs a 6.31-inch 1.5K LTPO AMOLED panel with a smooth 120Hz refresh rate, boosted by Vivo’s Ultra Motion algorithm for noticeably fluid animations. The 10-bit screen supports HDR10+, HDR Vivid and Ultra HDR across apps like YouTube and Netflix, delivering rich but well-controlled colours with excellent overall calibration.
There’s also a Visual Enhancement mode if you prefer a punchier look, though the default profile already feels lively without going overboard. For protection, Vivo uses SCHOTT Xensation XT Core. It isn’t quite on the level of Gorilla Glass Victus 2, but it’s still dependable for everyday safety.
Brightness peaks at 2000 nits globally and hits a local high of 4500 nits, making outdoor visibility solid even under harsh sunlight. The ultrasonic in-display fingerprint reader is fast, accurate and easy to trust.
The Vivo X300’s battery life was stronger than expected. Its 6040mAh cell, combined with 90W wired and 40W wireless charging, easily carried me through a full day of heavy use — everything from long camera sessions to nonstop streaming and even intensive gaming. Only during multiple benchmark loops did it drain a bit quicker, but it still made it to the evening without stress.
On most days, I consistently got around 7–8 hours of heavy usage on a single charge. A full recharge takes roughly an hour, which feels reasonable considering the massive battery size.
The Vivo X300 delivers performance that comfortably sits in flagship territory, even though it’s not completely immune to occasional heat spikes. It’s powered by the Dimensity 9500 chipset built on a 3nm process, paired with up to 16GB of LPDDR5X RAM and 512GB of UFS 4.1 storage. In everyday use, the phone feels fast, fluid, and consistently reliable, whether you’re juggling multiple apps, editing photos, or zipping through social media, it never shows any hesitation.
Benchmarks back this up. The X300 scored around 3.3 million on AnTuTu with only mild warmth during the run, while Geekbench results came in at 3278 for single-core and 9825 for multi-core. These numbers place it right alongside other 2025 flagships. In a 20-minute CPU throttling test with 30 threads, the chip dipped to roughly 76 percent of its peak performance. That’s still respectable, though the heat during this specific stress test was noticeable.
When it comes to gaming, the X300 handles titles like Call of Duty Mobile smoothly at basic settings. You’ll feel a bit of warmth near the camera module after longer sessions, but it never becomes uncomfortable. Vivo’s new Glacial Cooling system also kicks in effectively, helping the phone cool down faster than expected once gameplay stops.
In everyday performance, even for heavy users, the device stays cool, responsive, and stable. It’s a dependable flagship for gaming, content creation, and everything in between.
The biggest upgrade on the Vivo X300 is easily the software. It runs Vivo’s new OriginOS 6 based on Android 16, and the difference is obvious the moment you unlock the phone. The redesigned icons, smoother animations, and refreshed control centre give the interface a cleaner, more premium look. Origin Island adds an interactive layer for apps like Maps, Music, and Clock, though it still needs wider app support to reach its full potential.
What really stands out is the overall refinement. Funtouch OS often felt a bit scattered, but OriginOS 6 feels far more organised and visually consistent, even if some of the translucent elements clearly take cues from iOS 16’s liquid-glass style.
There are genuinely useful additions as well, including phone-to-PC mirroring and cross-device note syncing. The AI suite is stacked too, with text and image generation, AI Circle for search, Gemini-powered features, and handy editing tools like object erasers and background expand options.
Vivo is also promising long-term support with 5 years of OS updates and 7 years of security patches, ensuring the X300 stays reliable well into the future.
The Vivo X300 stays true to Vivo’s imaging-first legacy. Powered by the Dimensity 9500’s built-in processing and supported by Vivo’s in-house VS1 and V3+ imaging chips, the camera system produces consistently impressive photos and videos. The 200MP main sensor delivers rich, detailed shots with excellent colour accuracy and dynamic range. Skin tones look natural, and the phone handles complex lighting conditions with confidence.
The 50MP 3x periscope telephoto lens also holds up well. Colours remain consistent with the main camera, and portrait mode, especially at 100mm, looks almost DSLR-like with sharp detail, clean separation, and realistic texture. In bright conditions, results are strong, though very fine detail can occasionally dip.
The ultrawide is where the system stumbles slightly. Despite using a 50MP sensor, images sometimes appear softer and less detailed, but switching to the high-resolution mode improves sharpness noticeably. Selfies from the 50MP front camera look crisp with accurate skin texture and pleasing depth.
In low light, the main sensor performs impressively, keeping noise low and detail high. Telephoto shots soften a bit and portrait edge detection can slip around hair, but overall output remains reliable.
For video, the rear camera shoots up to 4K 120fps while the front goes up to 4K 60fps. Footage is good overall, though finer detail can waver at times, and the standard X300 misses out on Dolby Vision. Even with those drawbacks, the X300 remains one of the strongest all-round camera phones available, especially for still photography.
After pushing the Vivo X300 through everything from heavy multitasking to camera stress tests, calling it “good enough” would be selling it short. Sure, the ultrawide camera needs work and parts of OriginOS 6 clearly take inspiration from elsewhere, but none of that overshadows the bigger picture.
The X300 gets the fundamentals absolutely right. Smooth, reliable performance, standout main and telephoto cameras, a premium build, strong battery life, and a compact form factor that feels almost rare in 2025’s flagship world.
I liked the X200 last year, but the X300 makes an even stronger mark. If you want a compact flagship without compromising on core features, this one is genuinely easy to recommend.
