Smartphones with compact footprints often come with compromises. You usually get a smaller battery, trimmed-down camera features, or lower display specs just to squeeze everything into a sub-6.4-inch body. But the Vivo X300 flips that narrative. It’s compact, yes, with a 6.31-inch display, but the rest of its spec sheet reads like a full-sized flagship. That’s what makes it stand out in 2025’s crowded compact flagship space.
1. Compact phone with flagship energy
The first thing that sets the Vivo X300 apart is its 6.31-inch LTPO OLED panel with symmetrical 1.05mm bezels on all sides. Even Apple’s iPhone 17 and Xiaomi 17, both compact contenders, don’t offer this kind of uniformity.
Apple finally added 120Hz ProMotion to its base iPhone, but Vivo goes further with a variable refresh range from 1Hz to 120Hz, 2160Hz PWM dimming, full DC-like dimming, and a local peak brightness of 4500 nits. This is brighter than the Xiaomi 17’s 3500 nits and significantly ahead of the Galaxy S25’s 2600 nits.
Under the hood, the X300 packs MediaTek’s new Dimensity 9500 chip, built on a 3nm process and scoring over 4 million on AnTuTu 11. That performance bracket is similar to the Snapdragon 8 Elite Gen 5 inside the Xiaomi 17.
Unlike the Pixel 10 Pro, which still lags slightly in GPU-intensive tasks with the Tensor G5, the Vivo X300 delivers flagship-level performance without thermal throttling. It also stays cool thanks to an advanced vapor chamber setup.
2. Cameras built for serious results
Here’s where the X300 starts to flex. It doesn’t just throw in a few decent cameras to check the box. It includes a 200MP Samsung HPB primary sensor, a 50MP ultra-wide shooter, and a 50MP Sony LYT602 periscope telephoto camera with telemacro. That’s a three-lens stack tuned for both zoom and close-ups, with Zeiss optics and the same V3+ imaging chip used in the Pro model.
Compare this to the iPhone 17, which still settles for a dual-camera setup with a 48MP main and ultra-wide. Or the Galaxy S25, which has a 50MP main sensor, but smaller auxiliary sensors and no periscope zoom. Even Xiaomi’s Leica-branded setup on the 17, while solid with its Light Fusion 950 sensor, doesn’t match the sheer resolution or telephoto macro versatility the X300 brings.
Vivo also sells a 2.35x Zeiss teleconverter that clips onto the camera module. It features 13 high-transparency glass elements and ultra-low dispersion coatings. No other compact phone offers anything close to this level of optical flexibility.
3. Big battery in a light body
Despite being smaller and thinner than many of its rivals, the Vivo X300 still manages to pack a 6040mAh battery. It doesn’t match the sheer size of the Xiaomi 17’s 7000mAh cell, but it’s still significantly larger than most other compact phones in its class.
The Pixel 10 Pro comes with a 4870mAh battery, while the iPhone 17 is estimated to have around 3692mAh. The X300 delivers that capacity in a slim 7.95mm body and a manageable 190g weight, which makes the battery-to-weight ratio particularly impressive.
Charging is just as capable. The phone supports 90W wired charging, 40W wireless charging, and reverse wireless charging. Samsung’s 25W wired charging on the base Galaxy S25 falls far behind in comparison.
4. Compact size without compromise
Vivo doesn’t skimp on materials or extras. You still get an ultrasonic in-display fingerprint sensor, IP68 and IP69 dual certification for dust and water resistance, stereo speakers, and support for the latest wireless standards like Wi-Fi 7 and Bluetooth 6.
There’s even an infrared sensor, something Google and Apple continue to ignore, and support for NavIC, making it one of the most complete compact devices for India and other supported regions.
5. The Takeaway
In a world where compact phones often feel like stripped-down versions of their bigger siblings, the Vivo X300 feels more like a compressed flagship without compromises.
It is a rare Android phone that delivers strong camera capabilities, battery life, and a premium display in a form factor that fits comfortably in the hand. If you’ve been waiting for a compact phone that doesn’t ask you to settle, the X300 is worth a serious look.
