Display, Design, and Everyday Comfort
The display is one of the vivo X300’s strongest areas. Its 1216 x 2640 resolution produces approximately 460 pixels per inch, while the adaptive refresh rate can scale from 1 Hz to 120 Hz. This range can help balance fluid scrolling with lower power use during static content.
The panel is rated for up to 2,000 nits of standard maximum brightness and up to 4,500 nits in HDR. A recorded peak brightness test reached 2,685 nits, although real-world brightness depends on the mode, content, ambient conditions, and regional configuration. The display also supports DCI-P3, Always-On Display, DC dimming, and a listed 300 Hz touch sampling rate.
| Display feature | Listed result | Practical importance |
|---|---|---|
| Panel type | AMOLED | Strong contrast and deep blacks |
| Resolution | 1216 x 2640 | Sharp text and detailed images |
| Refresh rate | Adaptive 1-120 Hz | Smooth motion with variable efficiency |
| Pixel density | 460 ppi | High clarity at normal viewing distance |
| HDR brightness | Up to 4500 nits rated | Better highlight visibility in HDR content |
| Protection | Reinforced glass | Added resistance to everyday scratches and impacts |
The chassis measures 150.57 mm tall, 71.92 mm wide, and 7.95 mm thick. At 190 grams, it remains relatively manageable for users who prefer a narrower phone. The rear uses glass, the frame uses metal, and color options include black, blue, red, pink, and purple.
The phone includes an in-display fingerprint scanner, stereo speakers, and an infrared port. There is no 3.5 mm headphone jack or FM radio. The listed speaker loudness test reached 92.2 dB, while Dolby Atmos is not listed among the supported features.
The vivo X300 is especially appealing if you want a high-resolution, compact AMOLED display with adaptive refresh and strong outdoor brightness potential.
Performance and Benchmark Results
The Dimensity 9500 is the central performance feature. It uses a 3-nanometer manufacturing process, an eight-core design, a maximum clock speed of 4.21 GHz, and MediaTek’s NPU 990. Graphics processing is handled by the Mali-G1 Ultra MP12 GPU with 1,536 shading units.
The available results indicate a phone aimed at demanding workloads. NanoReview lists a performance score of 96, a gaming category score of 94, and a connectivity score of 98. These are platform scores rather than guarantees for every application, so sustained performance can change with temperature, software updates, brightness, and workload duration.
| Benchmark | Result |
|---|---|
| Geekbench 6 single-core | 3,204 |
| Geekbench 6 multi-core | 9,874 |
| Geekbench 6 GPU compute | 25,501 |
| AnTuTu Benchmark 11 | 3,313,039 |
| 3DMark Steel Nomad Light | 3,119 |
| 3DMark Solar Bay | 12,817 |
| PCMark 3.0 | 15,165 |
Recent user-submitted AnTuTu results listed on the reference page included 3,182,222 on July 24, 2026, and 3,437,320 on July 23, 2026. The spread demonstrates why benchmark scores should be viewed as a range instead of a fixed result.
The listed vapor-chamber cooling system is important for longer sessions. In 3DMark Steel Nomad Light, the recorded stability result was 57%, with a graphics test result of 23 FPS. That suggests performance consistency can vary during extended graphics-heavy workloads.
Install Updates First
Finish the initial Android 16 and OriginOS 6 setup, then check for system and application updates before testing performance.
Configure Performance Preferences
Select your preferred refresh-rate behavior, display brightness, battery mode, and background-app permissions before comparing results.
Run Consistent Tests
Use the same benchmark version, battery range, room conditions, and performance mode for each test session.
Check Sustained Stability
Compare the first result with a later run to identify heat-related performance changes instead of relying on one score.
Do not compare scores from different benchmark versions as if they were identical. Temperature, software, battery level, and performance settings can materially affect results.
Camera Hardware and Imaging Features
The rear camera system combines a 200 MP standard camera, a 50 MP telephoto camera, and a 50 MP ultrawide camera. The main sensor is listed as Samsung ISOCELL HPB with a 23 mm focal length and an f/1.68 aperture. The telephoto camera uses a Sony LYT-602 sensor, a 70 mm focal length, and 3x optical zoom.
Optical stabilization is listed for both the standard and telephoto cameras. The ultrawide camera uses digital stabilization and provides a 119-degree field of view, making it useful for architecture, landscapes, and group scenes where a wider perspective is valuable.
| Camera | Resolution | Aperture | Stabilization | Primary role |
|---|---|---|---|---|
| Standard | 200 MP | f/1.68 | Optical | Main photos and everyday shooting |
| Telephoto | 50 MP | f/2.6 | Optical | 3x optical zoom and portraits |
| Ultrawide | 50 MP | f/2.0 | Digital | Wide scenes and group photos |
| Front | 50 MP | f/2.0 | Digital | Selfies and 4K video calls |
The rear system supports up to 4K video at 120 FPS, 1080p recording at up to 60 FPS, and 1080p slow motion at 240 FPS. It does not list 8K recording. The front camera supports 4K video at 60 FPS and uses phase-detection autofocus.
For still photography, the main camera’s larger listed sensor and optical stabilization should give it the strongest role in mixed lighting. The telephoto camera is the better choice when preserving detail at 3x magnification, while the ultrawide lens should be reserved for scenes where coverage matters more than maximum fine detail.
Use the main camera for general scenes, switch to the telephoto lens for natural-looking 3x framing, and choose ultrawide only when the composition requires additional coverage.
