Vivo X300

The Vivo X300 has a compact and slim physical profile, measuring 150.6 × 71.9 mm with a thickness of just 8 mm and a total volume of 86.63 cm³, while keeping its weight at 190 g. A standout aspect of its design is its IP69 waterproof rating, which certifies the device against water ingress at depths of up to 1.5 m. The handset is neither a rugged-grade device nor a foldable form factor, positioning it as a conventional candybar smartphone with a meaningful level of water protection built in.

The Vivo X300 features a 6.31″ OLED/AMOLED touchscreen with a resolution of 1216 × 2640 px and a pixel density of 460 ppi, delivering a sharp and detailed image. The panel operates at a 120Hz refresh rate with a 300Hz touch sampling rate, and its 8,000,000:1 contrast ratio reflects the deep blacks typical of OLED technology. It supports both HDR10 and HDR10+ for compatible content, and the Always-On Display feature allows basic information to remain visible without fully waking the screen. Dolby Vision is not supported, and there is no secondary screen or branded damage-resistant glass included.

The Vivo X300 is driven by the MediaTek Dimensity 9500, a 3 nm chipset with an 8-thread CPU configuration running at speeds of 1 × 4.21 GHz, 3 × 3.5 GHz, and 4 × 2.7 GHz using big.LITTLE architecture with Heterogeneous Multi-Processing. The SoC integrates a Mali G1 Ultra MP12 GPU clocked at 1750 MHz with 128 shading units and OpenCL 3 support, alongside integrated LTE. The device comes with 16 GB of LPDDR5 RAM running at 5333 MHz, a maximum memory capacity of 24 GB, a memory bandwidth of 85.3 GB/s, a 16 MB L3 cache, and 1024 GB of internal storage. It supports 64-bit processing and multithreading, and posts an AnTuTu score of 4,011,900, a Geekbench 6 single-core score of 3,781, and a multi-core score of 12,189.

The Vivo X300 features a multi-lens rear camera system with three sensors rated at 200 MP, 50 MP, and 50 MP, with apertures of f/1.7, f/2.6, and f/2.0 respectively, a focal length range of 15 mm to 70 mm, and 3x optical zoom. The main camera uses a CMOS sensor without back-side illumination and is supported by optical image stabilization, laser autofocus, phase-detection autofocus, and touch autofocus, with two flash LEDs that are not dual-tone or RGB. Video recording reaches 4K at 60 fps, with continuous autofocus during recording and slow-motion support, though HDR10 and Dolby Vision recording are not available. Manual controls extend to exposure, ISO, focus, and white balance, while manual shutter speed is absent; additional shooting modes include HDR, burst, panorama, timelapse, and RAW capture, but 360° panorama and 3D recording are not supported. The 50 MP single-lens front camera sits behind the display glass at a standard position — not under-screen — with an f/2.0 aperture and no front-facing flash.

The Vivo X300 runs Android 16 as a free and open-source operating system, supporting multiple user accounts and offering a broad set of privacy controls including clipboard warnings, location privacy options, camera and microphone access management, and the ability to block app tracking, though cross-site tracking blocking and Mail Privacy Protection are absent. Customization options cover theme customization, dynamic theming, dark mode, and an extra dim mode, while productivity is aided by split-screen multitasking, Picture-in-Picture, widgets, sharing intents, customizable notifications, notification permission controls, a media picker, full-page screenshots, Live Text, and the ability to play games while they download. The system also includes on-device machine learning, offline voice recognition, voice commands, device tracking, a battery health check, app offloading, and a child lock, though focus modes, Wi-Fi password sharing, Quick Start, and the ability to function as a PC are not available. OS updates are not delivered directly from the platform vendor, meaning software updates are dependent on the device manufacturer.

The Vivo X300 houses a rechargeable 6040 mAh battery with a built-in level indicator, supporting fast wired charging at 90W and wireless charging at 40W. The battery is non-removable and does not support reverse wireless charging, meaning it cannot be used to charge other devices wirelessly.

The Vivo X300 includes stereo speakers and supports both aptX and aptX HD for higher-quality Bluetooth audio transmission, while aptX Adaptive, aptX Lossless, and LDAC are not available. The device does not have a 3.5 mm headphone jack, so wired audio relies on an adapter or USB-C connection, and there is no built-in radio tuner.

The Vivo X300 supports 5G cellular connectivity alongside dual SIM capability and a maximum download speed of 10,700 Mbit/s, with Wi-Fi 4 through Wi-Fi 7 (802.11n/ac/ax/be) and Bluetooth 5.4 also on board. It features a USB Type-C port running USB 3.2, NFC, an infrared sensor, a fingerprint scanner, GPS with Galileo support, a gyroscope, an accelerometer, and a compass, covering a solid range of sensors and biometric options. There is no external memory slot, HDMI output, barometer, heart rate monitor, ANT+ support, 3D facial recognition, iris scanner, or built-in projector, and the device does not include a stylus, DLNA certification, crash detection, or emergency SOS via satellite.

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