vivo X300 FE quietly enters the market with Snapdragon 8 Gen 5 and massive battery

vivo has quietly expanded its X-series lineup with the new X300 FE, a compact flagship smartphone that appears to be a rebadged version of the China-exclusive vivo S50 Pro mini with a minor spec bump. The device is now listed on vivo's official Russian website, though it's not yet available through the company's official online store.

The X300 FE brings a familiar set of high-end specifications in a more compact form factor. At its core is Qualcomm's Snapdragon 8 Gen 5 (non-Elite) chipset, paired with 12GB of LPDDR5X Ultra RAM and either 256GB or 512GB of UFS 4.1 storage. This represents a solid mid-range flagship configuration that should deliver excellent performance for most users.

One of the most notable features of the X300 FE is its display. The phone sports a 6.31-inch LTPO AMOLED panel with FHD+ resolution and a variable refresh rate that can scale from 1Hz to 120Hz. This adaptive refresh rate technology helps balance smooth visuals with battery efficiency, adjusting based on content being displayed.

Photography enthusiasts will appreciate the camera setup, which includes a 50MP main sensor (IMX921) and a 50MP telephoto lens (IMX882) with 3x optical zoom. The third camera is an 8MP ultrawide lens. The camera module is housed in a distinctive visor design that's become increasingly popular in recent smartphone designs.

Durability is a strong point for the X300 FE, which carries both IP68 and IP69 ratings. This dual certification means the phone is protected against dust, immersion in water, and high-pressure water jets - making it one of the more rugged offerings in the mid-premium segment.

On the software front, the X300 FE runs OriginOS 6 based on Android 16, with vivo promising 5 years of OS updates and 7 years of security patches. This extended support is becoming increasingly important as users keep their devices longer and expect longer software lifecycles.

The battery specifications are particularly impressive. The X300 FE packs a massive 6,500mAh Silicon-Carbon (Si-C) battery, which is significantly larger than what most flagship phones offer. This is paired with 90W wired charging and 40W wireless charging capabilities, ensuring that the large battery can be replenished quickly when needed.

Connectivity sees a small but notable upgrade over its S50 Pro mini counterpart. The X300 FE features Bluetooth 6.0, replacing the Bluetooth 5.4 found in the Chinese model. While this might seem like a minor change, Bluetooth 6.0 brings improvements in connection stability, range, and power efficiency.

Color options for the X300 FE include Moonlight White, Cool Purple, and Graphite Black, giving potential buyers a decent range of aesthetic choices.

Currently, the X300 FE is available through third-party retailers in Russia with a starting price of RUB 60,124 (approximately $770) for the 12GB/256GB configuration. The phone isn't yet available through vivo's official online store, suggesting this might be an initial soft launch before wider availability.

Looking at the broader market context, the X300 FE appears to be vivo's answer to the growing demand for compact flagship devices. With its 6.31-inch display, it sits in a sweet spot between the increasingly large mainstream flagships and the compact phone niche. The combination of high-end specs, a large battery, and a more manageable size could make it appealing to users who want flagship performance without the bulk of larger devices.

However, some potential buyers might be disappointed by the camera configuration. As one reader noted in the comments, the inclusion of an 8MP ultrawide lens alongside the two 50MP sensors might have been better replaced with a more compact overall design, perhaps in a 6.1-inch form factor with just the two main cameras.

Another point of consideration is the device's weight. While specific weight figures aren't provided in the listing, the combination of a large battery and premium build materials typically results in a heavier device, which could be a drawback for users prioritizing one-handed use and pocketability.

As vivo continues to expand its X-series lineup, the X300 FE represents an interesting addition that bridges the gap between compact design and flagship specifications. Whether it will see wider international release remains to be seen, but its appearance in Russia suggests vivo is testing the waters for this particular configuration in global markets.

The X300 FE joins a competitive segment of compact flagships, going up against devices like the iPhone 15/16 series and potentially the upcoming Google Pixel 9 series compact models. Its success will likely depend on how well it balances its impressive specifications with its physical ergonomics and how vivo prices it in different markets.
