The Vivo X300 lineup is heating up, and if you’ve been waiting for a compact flagship or a photography powerhouse, there’s plenty to get excited about. Following the brand’s recent expansion of its X-series, two new models—the X300 FE and X300 Ultra—are now inching closer to release. The FE just popped up on key certification sites, while the Ultra is rumored to ship with something we rarely see: a dedicated dual-lens teleconverter kit.
Let’s break down what’s coming.
Vivo X300 FE: A Compact Flagship with Unexpected Power
If you’re someone who wants flagship-level performance without the bulk of a massive phone, the X300 FE is shaping up to be a compelling option. The device—model number V2537—has now appeared on both IMDA and TUV certification listings. That’s typically a strong signal that a launch is imminent.
The TUV certification points to 90W wired fast charging, while the IMDA listing confirms 5G, Wi-Fi, Bluetooth, and NFC support. So connectivity is covered, and charging should be impressively quick.

But the real story is what’s inside. Despite its compact build, the X300 FE is rumored to pack:
- A Snapdragon 8 Gen 5 chipset, paired with LPDDR5X RAM and UFS 4.1 storage
- A 6.31-inch OLED display with a 120Hz refresh rate
- A surprisingly large 6,500mAh battery using silicon-carbon tech for better endurance
- A triple camera setup: 50MP primary, 50MP periscope telephoto, and an ultra-wide lens
- A 50MP ZEISS-optimized front camera
- IP68/IP69 ratings and a premium glass-and-metal build
For a phone that’s being described as compact, those specs are anything but small. If you’ve been frustrated by small phones that compromise on battery or camera, this one might finally break the mold.
Vivo X300 Ultra: Serious Hardware Meets Pro-Level Optics
Now, if photography is your priority, the X300 Ultra is where things get really interesting. According to recent rumors, Vivo is preparing a dual-lens external teleconverter kit for this model—something that leans into professional photography territory.
The setup is said to include a 400mm fixed-focus lens, with support for 200mm focal-length shooting. You’d likely switch between the two depending on the shot, rather than using them simultaneously. Built around Vivo’s V-mount platform, it’s designed to deliver a true optical zoom experience that goes beyond typical smartphone capabilities.
Under the hood, the X300 Ultra is expected to feature:
- A Snapdragon 8 Elite Gen 5 processor, offering top-tier gaming and multitasking performance
- A dual-camera system with two 200MP sensors (one from Sony, one from Samsung), plus a 5MP multispectral camera and a 50MP ultra-wide lens
- ZEISS T* coating and optical image stabilization to enhance image quality
- A massive 7,000mAh battery with 100W wired and 40W wireless charging
- IP69 dust/water resistance and USB 3.2 support
It’s the kind of spec sheet that makes you do a double take. Between the external lens kit and the internal camera hardware, Vivo seems to be targeting users who want DSLR-like flexibility without carrying a separate camera bag.

What This Means for You
Whether you’re after a compact daily driver that doesn’t skimp on battery or camera, or a full-fledged imaging beast with pro-level attachments, the X300 series appears to be shaping up with clear intent. The FE brings flagship features into a smaller footprint, while the Ultra pushes the boundaries of what a phone camera can do.
Certifications are in place, leaks are getting more detailed, and the timeline seems short. If you’ve been holding out for a new Vivo X-series device, it looks like the wait is nearly over.
