A Deep Dive into the Vivo X300

In a crowded smartphone market, the Vivo X300 stands out not just as another flagship device, but as a serious contender for photography lovers, power users, and anyone who wants top-tier performance in a relatively compact form. With its powerful hardware, thoughtful design, and advanced camera system, the X300 aims to strike a perfect balance between portability, productivity, and imaging prowess. Here’s a detailed look at what makes the Vivo X300 compelling—and where it could be better

Design and Build: Compact Yet Premium

One of the first things that strikes you about the Vivo X300 is how well it combines size and sophistication. The phone measures just 150.57 × 71.92 × 7.95 mm, weighing in at about 190 grams

These dimensions make it unusually compact compared to many modern flagship devices, delivering a more comfortable grip without compromising on screen or performance.

Vivo has outfitted the X300 with a unibody 3D glass design framed by metal edges, giving it a premium feel. The symmetrical bezels are ultra-slim—just 1.05 mm—which helps the display feel immersive without the phone feeling too large in the hand

The finish is clean, elegant, and polished; available color variants include Phantom Black, Mist Blue, Halo Pink, and others

Notably, the X300 also holds up well in less-than-ideal conditions: it has both IP68 and IP69 ratings, meaning it is resistant to dust and water under even quite severe environments.

That level of robustness is impressive for a phone that aims to be sleek and refined.

Display: Bright, Fast, and Gentle on the Eyes

Though compact, the display doesn’t compromise. The X300 features a 6.31-inch LTPO AMOLED screen, which provides a rich visual experience.

The resolution is 2640 × 1216, giving about 460 pixels per inch—sharp enough to make text, images, and video feel crisp and detailed

What really elevates the screen is the 120 Hz refresh rate, which ensures fluid scrolling, smooth animations, and a more responsive feel overall

On top of that, Vivo includes advanced eye‑care technology: 2160 Hz PWM dimming combined with DC-dimming helps reduce flicker and eye strain

The display also supports a wide color gamut (100% P3) and up to 4,500 nits peak brightness, making it vivid whether you’re indoors or outside

Performance: Flagship-Level Power Under the Hood

Under the hood, the Vivo X300 packs a serious punch. It runs on the MediaTek Dimensity 9500, built on a 3 nm process.

The CPU configuration is robust: one ultra-core at 4.21 GHz, three performance cores at 3.5 GHz, and four efficiency cores at 2.7 GHz.

For graphics, it uses the Arm G1‑Ultra GPU, which handles demanding tasks like gaming, content creation, or even multitasking with ease.

To support that power, the phone offers 12 GB or 16 GB of LPDDR5X RAM, paired with fast UFS 4.1 storage in different capacities—256 GB, 512 GB, and even 1 TB.

The high-end RAM‑storage combo ensures that apps open quickly, large files are handled smoothly, and multitasking feels seamless.

On the software side, the X300 runs OriginOS 6 based on Android 16, which brings a fresh, dynamic user interface and optimizations for performance and efficiency.

According to hands-on sources, Vivo also leverages features like Ultra-Core Computing, Memory Fusion, and Dual Rendering, which collaboratively make for faster app launches, more stable frame rates, and smoother overall performance

Camera: A Revolutionary Imaging System

Where the Vivo X300 truly shines is its camera system. On the back, it has a triple-lens setup, all developed in collaboration with ZEISS.

he main sensor is a 200 MP ZEISS unit, which is massive in resolution and offers extraordinary detail.

Assisting this are a 50 MP periscope telephoto lens (with 3x optical zoom) and a 50 MP ultrawide lens—both also ZEISS‑tuned

The main camera is equipped with optical image stabilization (OIS), and the telephoto lens also supports OIS, which helps with steady shots even when zoomed in.

The device supports advanced imaging features like Intelligent HDR, laser autofocus, Pro mode, time-lapse, and more

On the front, there’s a 50 MP ZEISS wide-angle selfie camera, also capable of 4K video.

Video capabilities are top-notch: the rear system supports 4K recording at up to 120fps, and lower resolutions go even higher in frame rate.

All of this comes together to give users a pro-level mobile photography experience in a compact form.

Battery and Charging: Endurance with Speed

Despite its compact size, the X300 packs in a 6,040 mAh Si/C Li-ion battery.

For many users, that is more than enough to last a full day of mixed use—especially when paired with clever software power optimizations.

Charging is another strength: the phone supports 90 W wired Flash Charge, allowing very fast recharges, plus 40 W wireless charging for added convenience.

There’s even reverse wired charging, meaning you could potentially share power with smaller devices if needed

Moreover, the phone uses a blue‑volt semi‑solid battery, which according to Vivo has been tested to last up to five years under repeated use, highlighting longevity alongside performance

Connectivity, Extras & Durability

Connectivity options on the X300 are robust:

5G support for high-speed mobile data.

Wi-Fi 7 for super-fast wireless networking.

Bluetooth 5.4, NFC, and even an IR (infrared) port are present.

For security, the phone includes an ultrasonic under-display fingerprint sensor, which is fast and reliable

The X300 features a 4K VC vapor‑chamber cooling system, helping to maintain thermal stability even under heavy workloads

All this is wrapped in a device that feels solid yet refined, thanks to its premium materials and intelligent engineering.

Strengths: What the Vivo X300 Does Really Well

Photography Powerhouse: The 200 MP sensor, ZEISS optics, and versatile lenses make it exceptionally capable for both creative and practical photography.

Compact High Performance: It delivers flagship-level performance (Dimensity 9500, fast memory) in a form factor that is easier to handle than many larger phones.

Fast Charging + Long Battery Life: Big battery capacity combined with 90 W wired and 40 W wireless charging gives both endurance and convenience.

Eye-Friendly Display: The high refresh rate, wide color gamut, and dual-dimming tech balance visual quality and eye comfort.

Durability: IP68/IP69 water and dust resistance adds robustness, making it more than just a delicate glass phone.

Final Thoughts

The Vivo X300 is a thoughtfully engineered smartphone that brings many flagship-level features into a more compact, elegant form. It doesn't force you to compromise on performance or camera capability just because it's smaller. With its powerful Dimensity 9500 processor, advanced ZEISS-backed triple camera system, high-capacity battery with very fast charging, and IP-rated durability, it's clear that Vivo is positioning the X300 as a serious contender in the high-end space.

However, it's not without trade-offs. Users who prioritize speaker quality or who are sensitive to software quirks may need to weigh those carefully. And, like many flagships, you'll pay a premium for the advanced hardware.

Overall, the Vivo X300 is a compelling “all-rounder” for anyone looking for a premium smartphone experience in a compact package—especially if photography is a priority. It represents a smart, balanced choice in a world where bigger often gets mistaken for better.
