Vivo X300 Ultra Specification
The Vivo X300 Ultra is a powerhouse that does not hide it. Announced in late March 2026 and available by early April, this phone is big and substantial, measuring about 163mm tall and weighing between 232g and 237g, depending on the model. It feels premium with a glass front and back held together by an aluminum frame, and it is seriously tough IP68/IP69 rated means it is dust-tight and can survive being dunked in 1.5 meters of water for half an hour, plus it handles hot, high-pressure water sprays. The display is a gorgeous 6.82-inch LTPO AMOLED with a buttery smooth 144Hz refresh rate, over a billion colors, and Dolby Vision/HDR10+ support. It also hits an impressive measured brightness of 1935 nits, so sunlight visibility is not an issue. Under the hood, you get Android 16 with Vivo’s OriginOS 6, powered by the Snapdragon 8 Elite Gen 5 chipset built on a 3nm process and an Adreno 840 GPU.
The Vivo X300 Ultra is basically a professional camera that happens to make calls. On the back, you get not two but three massive sensors: a 200MP wide camera with gimbal-style optical stabilization (OIS), a 200MP periscope telephoto with 3.7x optical zoom, and a 50MP ultrawide (116 degrees) that also has OIS. And if that is not enough, there are optional add-on Zeiss zoom lenses (200mm and 400mm) that clip or attach for even more reach. You also get laser autofocus, a color spectrum sensor, Zeiss optics with their famous T* lens coating, and pro-grade video features like 8K recording, 4K at up to 120fps, 10-bit Log, and Dolby Vision HDR. The selfie camera is a sharp 50MP shooter with autofocus. Simply put, this is a mobile photography studio.
Battery life is top notch the international version packs a 6600mAh silicon carbon battery (Europe gets 6400mAh), and it supports 100W wired charging, 40W wireless, plus reverse wired and wireless charging to juice up your earbuds or another phone. In tests, it lasted nearly 16 hours of active use. On the connectivity side, you get Wi-Fi 7, Bluetooth 5.4 with high quality codecs like aptX Lossless, and even an infrared port to control your TV or AC. The fingerprint sensor is under the display (ultrasonic, so it works with wet fingers), and a satellite SOS feature for calls and messages is available on the 1TB storage 16GB RAM model. The phone comes in Black, Silver, or Green and pricing starts at $1694 (Rs 1,59,999 in India). It earns a Class B for energy and free fall durability but a Class C for repairability so treat it well, but know it is built to last.

Vivo X300 Ultra Pros and Cons
Based on the above specs, you can see the list of pros and cons (advantages and disadvantages) of the Vivo X300 Ultra smartphone.
Pros
- The phone includes two 200MP cameras (main and periscope telephoto). This lets you take incredibly detailed photos of wildlife or sports players, without losing any quality.
- The smartphone supports 100W wired charging and 40W wireless charging.
- The smartphone has a 6600 mAh silicon-carbon battery. This phone easily lasts a full day and well into a second day of heavy use.
- The display reaches 1935 nits of peak brightness and runs at a 144Hz refresh rate. This means the screen stays crystal clear even under direct summer sunlight, and scrolling through apps or games feels incredibly smooth.
- The phone offers emergency SOS via satellite (on the 16GB+1TB model). If you are hiking in the mountains or sailing where there is no cell signal, you can still send emergency calls and messages to get help.
- The device supports 8K video recording at 30fps and 4K at up to 120fps with 10-bit Log and Dolby Vision HDR.
- The smartphone has IP68/IP69 dust and water resistance. You can submerge it in 1.5 meters of water for 30 minutes, and it can even survive high-pressure, high-temperature water jets perfect for outdoor work or beach trips.
- The phone includes ultrasonic fingerprint sensor under the display. This works even when your fingers are wet or oily.
- The phone supports reverse wired and reverse wireless charging.
Cons
- The phone does not have a 3.5mm headphone jack. You cannot plug in your existing wired headphones directly, meaning you must buy Bluetooth earphones or carry a separate USB-C to 3.5mm adapter.
- The smartphone is very heavy at 232g or 237g.
- The phone is extremely expensive at around Rs 1,59,999. This price is higher than many gaming laptops or even a used car, making it unaffordable for the average buyer.
- No expandable storage means you cannot add a microSD card later, so you must delete files if the 256GB fills up with 4K videos and photos.
- Class C repairability means that fixing a cracked screen or damaged battery is difficult and expensive.
- OriginOS 6 changes standard Android with many pre-installed apps and a cluttered look, which some users find confusing.
