Vivo X300 FE 5G and OnePlus 15s 5G are set to join the compact flagship race, with new leaks revealing key specifications and an expected India launch soon. As brands like OnePlus and Oppo have already launched their latest flagships in India, Vivo is gearing up to introduce the X300 series on December 2, while compact variants such as the Vivo X300 FE 5G and OnePlus 15s 5G are now in the spotlight. A known tipster, Debayan Roy (Gadgetsdata), has shared the first detailed look at these phones, including display, processor, battery, and camera information, suggesting that compact flagships are going to be a major trend in 2026.
Vivo X300 FE 5G: Compact but powerful
The Vivo X300 FE 5G is tipped to feature a 6.3-inch flat OLED display with a 120Hz refresh rate and 1.5K resolution, offering a smooth and sharp viewing experience in a compact form factor. Under the hood, it is expected to be powered by the Snapdragon 8 Gen 5 processor, which is debuting globally and will likely bring top-tier performance for gaming and multitasking.
Despite its smaller size, the Vivo X300 FE 5G may pack a massive 6500mAh battery with support for 90W wired charging, aiming to deliver all-day backup with very fast charging speeds. For cameras, leaks suggest a triple setup: a 50MP main sensor, a 50MP telephoto lens with 3x zoom, and an ultrawide camera, making it suitable for versatile photography in day and night scenarios
OnePlus 15s 5G: High refresh rate and huge battery
The OnePlus 15s 5G is also said to sport a 6.3-inch flat OLED display, but with an even higher 165Hz refresh rate along with 1.5K resolution, targeting users who want ultra-smooth visuals, especially for gaming and scrolling. This compact flagship will likely be powered by the Snapdragon 8 Elite Gen 5 processor, the same class-leading chip seen in the OnePlus 15 5G, ensuring flagship-level performance in a smaller body.
Camera-wise, the OnePlus 15s 5G is expected to carry a triple rear camera array with a 50MP main sensor, a 50MP telephoto lens, and an ultrawide unit, similar to other high-end OnePlus models. One of its standout points is the rumoured 7000mAh battery, which is unusually large for a compact phone and should offer excellent endurance along with fast charging support, as seen in other 15-series devices.
Design, build, and durability
Both Vivo X300 FE 5G and OnePlus 15s 5G are expected to come with a premium metal frame, giving them a solid in-hand feel and a flagship-grade design language. In addition, leaks mention an IP69 water-resistant rating for both devices, which is higher than the typical IP68 rating and suggests strong protection against dust and powerful water jets, making them more durable for everyday use and outdoor conditions.
These design and durability elements show that brands are not only focusing on raw performance but also on long-term reliability and premium ergonomics in the compact flagship segment.
India launch expectations
The tipster has indicated that the India launch of Vivo X300 FE 5G and OnePlus 15s 5G is expected soon, although there is no confirmed timeline or date yet. With Vivo’s X300 series already set for a December 2 unveiling and OnePlus expanding its 15 lineup in early 2026, these compact models are likely to follow shortly after the main flagships arrive in the market. There are also rumours that another compact flagship, possibly called Oppo 15 Mini, could join this race, making the compact premium category quite competitive in India.
Conclusion
Vivo X300 FE 5G and OnePlus 15s 5G are shaping up to be powerful compact flagships with high-end displays, new Snapdragon Gen 5 processors, big batteries, strong camera setups, and IP69 protection. For users who prefer smaller phones without compromising on performance or features, these upcoming models could be excellent options once they launch in India.
