Vivo X300 (256GB / 16GB RAM)

The Vivo X300 has a non-folding, standard-form design measuring 150.6 mm tall, 71.9 mm wide, and just 8 mm thick, with a total weight of 190 g and a volume of 86.63 cm³. One of its more notable physical attributes is its IP69 rating, which certifies the device as waterproof and capable of withstanding submersion down to 1.5 m, though it does not carry a rugged build designation.

The Vivo X300 uses a 6.31″ OLED/AMOLED touchscreen with a resolution of 1216 x 2640 px and a pixel density of 460 ppi, producing a sharp and detailed image across a single panel with no secondary screen. The display runs at a 120 Hz refresh rate with a 300 Hz touch sampling rate, and delivers a contrast ratio of 8,000,000:1, supporting both HDR10 and HDR10+ for high dynamic range content, though Dolby Vision is not supported. An Always-On Display mode is available, and the screen does not feature branded damage-resistant glass.

The Vivo X300 is powered by the MediaTek Dimensity 9500, a 3 nm chipset with an 8-thread CPU configuration running at up to 4.21 GHz on its prime core, alongside three cores at 3.5 GHz and four efficiency cores at 2.7 GHz, with big.LITTLE and HMP technologies enabling dynamic workload distribution. Graphics are handled by the integrated Mali G1 Ultra MP12 GPU, clocked at 1750 MHz with 128 shading units and OpenCL 3 support, while benchmark results stand at 4,011,900 on AnTuTu, 12,189 on Geekbench 6 multi-core, and 3,781 on the single-core test. The device comes with 256 GB of internal storage and 16 GB of DDR5 RAM running at 5333 MHz, offering a maximum memory bandwidth of 85.3 GB/s and support for up to 24 GB total memory, complemented by a 16 MB L3 cache, integrated LTE on the SoC, 64-bit support, and multithreading capabilities.

The Vivo X300 features a multi-lens rear camera system led by a 200 MP main sensor with an f/1.7 aperture, paired with two additional 50 MP lenses at f/2.6 and f/2.0, covering a focal range from 15 mm to 70 mm with 3x optical zoom and optical image stabilization. The rear system uses a CMOS sensor without back-side illumination, and autofocus options include phase-detection, laser, and touch autofocus, along with continuous autofocus during video recording. Video capture reaches up to 4K at 60 fps, with slow-motion recording supported, while HDR10 recording and Dolby Vision recording are not available; two LED flash units are present, though they do not form a dual-tone or RGB configuration, and there is no front-facing flash. Manual controls extend to exposure, ISO, focus, and white balance, though manual shutter speed is absent, and shooting modes include burst, panorama, timelapse, and RAW capture, while 360-degree panorama and 3D recording are not supported. The single-lens front camera resolves at 50 MP with an f/2.0 aperture and sits in a standard position rather than under the display.

The Vivo X300 runs Android 16 and ships with a broad set of privacy and usability features, including clipboard warnings, location privacy options, camera and microphone access controls, and the ability to block app tracking, though cross-site tracking blocking and Mail Privacy Protection are not present. The interface supports theme customization, dynamic theming, dark mode, and an extra dim mode, while productivity is aided by split-screen multitasking, Picture-in-Picture, a media picker, full-page screenshots, sharing intents, customizable notifications, widgets, and the ability to play games while they download. It also includes on-device machine learning, Live Text, offline voice recognition, voice commands, multi-user support, app offloading, a child lock, battery health check, and device tracking, though focus modes, Wi-Fi password sharing, Quick Start, and the ability to function as a PC are not supported. OS updates are not delivered directly from the OS vendor, and the platform is noted as free and open source.

The Vivo X300 is equipped with a 6040 mAh rechargeable, non-removable battery with a visible battery level indicator. It supports fast wired charging at 90W and wireless charging at 40W, though reverse wireless charging is not available.

The Vivo X300 features stereo speakers but omits a 3.5 mm headphone jack and has no built-in radio. For wireless audio, it supports aptX and aptX HD, while aptX Adaptive, aptX Lossless, and LDAC are not available.

The Vivo X300 supports 5G connectivity and accommodates two SIM cards, with wireless networking covering Wi-Fi 4 through Wi-Fi 7 (802.11n/ac/ax/be) and Bluetooth 5.4. It connects via USB Type-C with USB 3.2, includes NFC, and reaches download speeds of up to 10,700 Mbit/s, though there is no HDMI output, no external memory slot, and no DLNA certification. On-device sensors include a gyroscope, accelerometer, compass, GPS with Galileo support, an infrared sensor, and a fingerprint scanner, while a barometer, heart rate monitor, iris scanner, ANT+ support, motion tracking, optical tracking, and 3D facial recognition are all absent. Crash detection, emergency SOS via satellite, a built-in projector, and a stylus are likewise not included.

The Vivo X300 includes a video light, while its display is flat rather than curved and uses neither sapphire glass nor an e-paper panel.
