The vivo X300 Ultra is the company’s latest flagship, combining a rugged yet premium design with a 200MP camera system, a massive 6600mAh battery and Qualcomm’s Snapdragon 8 Elite Gen 5 chipset. With a 6.82-inch LTPO AMOLED display running at up to 144Hz, IP68 and IP69 protection and 100W wired fast charging, this device clearly targets demanding users who need top-tier performance for both everyday tasks and professional workloads.
On top of the raw hardware, vivo has also prepared a dedicated photography kit for the X300 Ultra, including a pro-style grip, teleconverters and filter rings, turning this smartphone into a serious mobile photography tool. The combination of powerful internals, advanced camera hardware and rich accessories makes the X300 Ultra one of the most ambitious and distinctive flagships of the year.
Flat design, solid frame and IP68/IP69 durability
With the vivo X300 Ultra, the brand moves away from the heavily curved aesthetics of previous generations and adopts a noticeably flatter front and back. The widened aluminium frame gives the phone a more substantial feel in the hand, while the glass panels on both sides keep the look premium and modern. At around 232g, this is not a light device, but it fits well within the category of serious, high-end flagships.
In terms of durability, the X300 Ultra stands out with both IP68 and IP69 ratings, offering resistance against dust, immersion in water and even high-pressure water jets. This level of protection, combined with the solid build, makes the device a compelling option for users who want a long-lasting phone that can handle harsher environments without sacrificing style.
LTPO AMOLED display with 144Hz refresh rate
The vivo X300 Ultra features a 6.82-inch LTPO AMOLED panel with a resolution of 3168×1440 and a pixel density of about 510ppi. The display supports an adaptive refresh rate of up to 144Hz, delivering extremely smooth scrolling, animations and gaming performance, while LTPO technology allows the phone to dynamically lower the refresh rate to save battery whenever possible.
In terms of image quality, the panel supports 1 billion colors, Dolby Vision, HDR10+ and HDR Vivid, making it one of the most versatile displays in the flagship segment. High-frequency 2160Hz PWM dimming helps reduce flicker at low brightness levels, which is easier on the eyes during extended use. The Ultra HDR feature also ensures that HDR photos and content captured by the camera are displayed with their full dynamic range on the screen itself.
Snapdragon 8 Elite Gen 5 power under the hood
At the heart of the X300 Ultra sits Qualcomm’s 3nm Snapdragon 8 Elite Gen 5 chipset, built around new Oryon V3 CPU cores and high clock speeds. Paired with an Adreno 840 GPU, this platform delivers more than enough performance for demanding games, video editing and heavy multitasking, all while maintaining stability and sustained performance over long sessions.
The device is available with 12GB or 16GB of RAM, alongside 256GB, 512GB or 1TB of internal storage. The use of UFS 4.1 storage translates into extremely fast read and write speeds, which in turn means snappy app launches, quick file transfers and reduced loading times. Altogether, the hardware configuration places the X300 Ultra among the fastest and most capable Android flagships currently available.
200MP camera system with powerful telephoto capabilities
The camera setup is one of the main highlights of the vivo X300 Ultra. The primary 200MP sensor with a large 1/1.12-inch size and gimbal-style optical stabilization is designed to capture highly detailed, low-noise images. Thanks to the large sensor and vivo’s image processing, the phone performs very well in low light, delivering photos with wide dynamic range and balanced, natural-looking colors.
Alongside the main camera, a 200MP telephoto lens with 3.7x optical zoom and macro capabilities turns the X300 Ultra into a serious tool for shooting distant subjects and close-up details. A 50MP ultra-wide camera covers landscapes, architecture and group shots. On the video side, the phone supports 8K recording at 30fps and 4K at up to 120fps, with 10-bit Log and Dolby Vision HDR profiles aimed at mobile filmmakers. The 50MP front camera with autofocus and 4K recording is also well-suited for vlogging and high-quality social media content.
6600mAh battery with 100W fast charging
One of the biggest upgrades in the vivo X300 Ultra is its 6600mAh battery, which represents a significant capacity increase over previous generations. Combined with the power-efficient 3nm Snapdragon 8 Elite Gen 5 and the adaptive LTPO display, this large battery enables full-day endurance under heavy use and can easily stretch to more than a day and a half with moderate usage.
For charging, vivo includes support for 100W wired fast charging, capable of bringing the big battery to a high charge level in a very short time. The phone also supports 40W wireless charging and reverse charging (wired and wireless), allowing it to top up other devices such as earbuds and smartwatches. In non-EU markets, a 100W USB-C charger and an e-marked, high-current USB-C to USB-C cable are included in the box for maximum convenience.
Accessories and dedicated photography kit
Unlike many competitors, vivo still offers a complete unboxing experience with the X300 Ultra. Inside the box, users will find the phone itself, a 100W charger, a USB-C to USB-C cable and a high-quality TPU case that matches the device’s color. The bundled cable is reinforced and rated for high current, ensuring reliable performance with the fast-charging system.
Beyond the basics, vivo has also created a dedicated Photography Kit for the X300 Ultra, with availability and exact contents depending on the region. The kit typically includes a pro-style grip with a physical shutter button, 200mm and 400mm teleconverters, filter rings and a quick-release leather strap. This set effectively turns the smartphone into a quasi-professional camera rig, making it particularly attractive to mobile photographers and content creators—though some elements of the kit may not be available in all markets, especially across Europe.
