Design and Colour Variants

OnePlus is introducing the 13s in three premium finishes: Black Velvet, Pink Satin, and Green Silk — the last of which is exclusive to the Indian market. The smartphone is designed to offer a compact yet high-end feel, keeping OnePlus’ signature craftsmanship intact while introducing new materials and textures to enhance grip and aesthetic appeal.

Powerful Hardware: Snapdragon 8 Elite & Cryo-Velocity Cooling

Under the hood, the OnePlus 13s is powered by Qualcomm’s Snapdragon 8 Elite chipset, a new generation flagship SoC designed to deliver peak performance while optimising energy consumption. To ensure that the phone remains cool even during intense tasks, it houses a 4400 sq mm Cryo-Velocity vapour chamber, paired with a back-cover cooling layer for effective thermal management.

In internal tests, the phone reportedly maintained stable frame rates for up to seven hours while playing Battlegrounds Mobile India (BGMI)—highlighting its gaming prowess and thermal efficiency.

Battery Life: Built for All-Day Use

OnePlus claims that the 13s can deliver up to 24 hours of battery life on a single charge during WhatsApp calls, and up to 16 hours of Instagram browsing, making it ideal for communication-heavy or content-consuming users.

While the battery capacity itself hasn’t been explicitly mentioned, such endurance figures suggest significant enhancements in both hardware efficiency and software optimisation.

All-New Plus Key: Replacing the Alert Slider

The traditional tri-state alert slider, a long-standing hallmark of OnePlus devices, has been replaced by a new “Plus Key”. This customisable button enables users to assign one-press actions for quick access to modes such as Sound, Vibration, Do Not Disturb, or even AI-powered tools and shortcuts. It reflects the company’s evolving approach to integrating smart functionality with hardware ergonomics.

Connectivity Upgrades Tailored for Indian Users

The OnePlus 13s brings a series of connectivity improvements that address real-world signal challenges. It features an advanced 360-degree antenna system comprising 11 antennas, including three high-performance modules and four-mode ultra-wideband low-frequency antennas.

These enhancements, along with OnePlus’ Signal-Balance Mode, are designed to mitigate signal drops from hand obstruction and environmental interference. The result? A claimed 60% improvement in signal strength, especially while using mobile networks in high-density areas.

G1 Wi-Fi Chipset and 5.5G Support

The OnePlus 13s is also the first device to feature the G1 Wi-Fi chipset, an in-house Wi-Fi solution tailored for Indian urban environments. Whether commuting through the Delhi Metro or stuck in a lift with weak network access, the chipset promises faster and more reliable Wi-Fi connectivity.

Additionally, the phone supports 5.5G, enabling it to connect to three network cells across different towers simultaneously, which can significantly enhance download/upload speeds and reduce latency.

Conclusion

With the OnePlus 13s, the company appears to be taking a bold step into the future of compact flagship smartphones. By offering innovative features like the Plus Key, improved thermal architecture, India-specific connectivity optimisations, and a powerful Snapdragon 8 Elite chipset, the device is well-positioned to attract premium users looking for performance, practicality, and design.

As OnePlus prepares to unveil the 13s on June 5, anticipation continues to grow. If the official performance and feature claims hold true, this could be one of the most compelling flagship offerings from OnePlus in 2025 — especially for Indian users.
