vivo X300 specs: Camera, Battery, Display & Performance

The vivo X300 is a compact flagship phone designed for buyers who want premium cameras and high-end performance without a large body. The vivo X300 specs include a 6.31-inch OLED display, MediaTek’s Dimensity 9500 chipset, fast UFS 4.1 storage, and a camera system led by a 200MP primary sensor.

The phone weighs 190g and uses a glass rear panel with a matte finish, paired with a matte aluminum frame. Its rounded camera module is prominent, but the compact footprint keeps the device comfortable for one-handed use. IP68 and IP69 ratings add protection against dust, water submersion, and heated water jets.

Video Highlights:

• Compact flagship design with a 6.31-inch OLED screen
• 200MP main camera and 50MP 3x telephoto camera
• Dimensity 9500 performance with Origin OS on Android 16
• Large battery options and fast wired, wireless, and reverse charging

The vivo X300 uses a 6.31-inch OLED display with a high resolution of approximately 460 pixels per inch. The panel supports a 120Hz refresh rate and LTPO technology, allowing the refresh rate to reduce to 1Hz during idle content to help manage power consumption.

The screen also supports 10-bit color depth and HDR10+ playback. In testing, automatic brightness reached nearly 2,000 nits, giving the display strong visibility outdoors. Thin bezels help the front feel more immersive without making the phone physically large.

The rear glass has a velvety matte finish that helps resist visible smudges. The aluminum frame uses a similar matte treatment, creating a consistent exterior. The large circular camera bump is the most noticeable design element and may cause some movement when the phone rests on a flat surface.

Stereo speakers provide good loudness, although sound quality is more average than exceptional. Vocals remain clear enough for videos and calls, but the high frequencies lack some refinement. An ultrasonic fingerprint sensor sits beneath the display and provides fast, reliable unlocking. The built-in IR blaster is another useful feature for controlling compatible household appliances.

The vivo X300 is powered by MediaTek’s Dimensity 9500, a flagship chipset intended to deliver a major performance and efficiency improvement over the previous generation. It handles demanding applications, multitasking, image processing, and gaming with the level of power expected from a premium 2026 phone.

Long stress tests show that sustained performance can reduce to roughly 60% of peak CPU performance as temperatures rise. This behavior is consistent with the thermal limits of other high-performance flagships, but users running extended workloads should expect some throttling rather than unlimited peak output.

Storage options include 256GB, 512GB, and 1TB capacities using UFS 4.1. There is no microSD expansion, so selecting the right capacity at purchase is important.

Origin OS runs on Android 16 and introduces a noticeably redesigned visual experience. Updated icons, revised typography, and customizable animations create a cleaner interface. The control center uses transparent, bubble-like toggles with brighter borders, while a dynamic-island-style area around the selfie camera displays contextual information for timers and media playback.

AI features include text proofreading, rewriting, text generation, real-time captions in multiple languages, and gallery tools for object removal or image expansion. Vivo also includes a connection center that brings connectivity options into a unified hub. Wireless file exchange between the X300 and an iPhone is supported after installing a specific app on the iPhone.

Battery capacity varies by market. European versions use a 5,360mAh battery, while versions sold elsewhere can carry a larger 6,040mAh capacity. This difference should be checked before purchase because it can affect endurance and represents one of the most important regional variations in the vivo X300 specs.

Testing of the larger-capacity version produced an active-use score of 17 hours and 31 minutes. That is a strong result for a compact flagship, especially considering the high-resolution display, powerful chipset, and advanced camera hardware.

The phone supports up to 90W wired charging. With the correct bundled adapter, a full charge took approximately 48 minutes. A 67W Power Delivery charger achieved a similar result at around 50 minutes. Wireless charging and reverse wireless charging are also supported.

For the best balance between battery life and responsiveness, leave the adaptive refresh rate enabled. LTPO allows the display to use 120Hz when scrolling while reducing the refresh rate during static content. Users who record long video sessions or play demanding games should also consider carrying a compatible high-output charger.

The camera system is the defining feature of the vivo X300. It combines a 200MP main camera, a 50MP telephoto camera with 3x optical zoom, and a 50MP ultrawide camera with autofocus. The front camera is also a 50MP autofocus unit, making the selfie camera a substantial upgrade for detail, portraits, and video calls.

The primary camera produces 12MP images by default. Photos show strong detail, natural fine textures, reliable white balance, and a wide dynamic range. Color is vivid without usually becoming artificial, although nighttime images can appear slightly oversaturated.

The 3x telephoto camera is particularly versatile. It delivers detailed zoom images with natural textures, attractive colors, and wide dynamic range. Because it can focus as close as 20cm, it also works well for close-up photography. Six-times digital crop remains usable in suitable lighting, while 10x results are more dependent on the subject and may lose fine detail in foliage or complex textures.

The autofocus ultrawide camera performs above the usual standard for this class. Daylight images retain plenty of detail and sharpness, while nighttime shots maintain good exposure, usable detail, and a broad dynamic range. The main camera and telephoto unit are also capable in low light, producing clean images with controlled noise and consistent exposure.

Portrait photography is a major strength. People shots show convincing skin tones, well-developed facial detail, and believable background blur. The telephoto camera creates a naturally defocused background that can produce a more flattering perspective than a close portrait taken with the main camera.

Video recording reaches 4K at 60 frames per second across all cameras. The main camera can also record 4K at 120 frames per second for slow motion. 10-bit log recording is available for users who want greater flexibility during color grading.

Daylight 4K video from the main camera offers strong detail, good sharpness, broad dynamic range, and realistic colors. Ultrawide and telephoto video remain capable, though they can be slightly less sharp than the primary camera. Stabilization is one of the phone’s strongest video features, smoothing walking movement and making handheld footage appear unusually steady.

The vivo X300 is a strong fit for users who want flagship performance in a smaller body without giving up a versatile camera system. Its 6.31-inch screen is easier to manage than oversized alternatives, while the Dimensity 9500 provides enough power for demanding apps and high-performance games.

Photography enthusiasts benefit from the combination of a high-resolution main camera, 3x telephoto lens, autofocus ultrawide, and improved selfie camera. Video creators also gain 4K60 recording across the camera system, 4K120 slow motion from the main camera, 10-bit log support, and effective stabilization.

There are a few compromises to consider:

• The speaker quality is competent but not class-leading.
• Storage cannot be expanded with a microSD card.
• Battery capacity differs between Europe and other markets.
• Sustained heavy workloads can cause noticeable performance reduction.
• The camera bump is large compared with the phone’s compact body.
• Origin OS may feel unfamiliar to users accustomed to a simpler Android interface.

Overall, the vivo X300 offers a compelling combination of portability, imaging quality, display technology, and battery endurance. It is especially attractive when camera performance matters as much as raw specifications. Buyers should confirm the regional battery capacity and storage configuration before committing.
