OnePlus is preparing to expand its premium smartphone lineup in India with the upcoming OnePlus 15s, expected to follow the OnePlus 13s which arrived exclusively in the Indian market in mid-2025. While the brand continues to focus on its global flagship line, the S-series has emerged as a dedicated performance-driven option for the Indian audience, and early details now hint at a major upgrade for 2026.
According to the latest leaks, the OnePlus 15s will feature a 6.31-inch 1.5K flat LTPO OLED display designed to deliver fluid visuals with improved power efficiency. The device is expected to be powered by Qualcomm’s Snapdragon 8 Elite Gen 5 chipset, positioning it among the most powerful Android smartphones of its launch timeline. The phone may also offer upgraded imaging capabilities, including a 50MP primary camera paired with a 3x telephoto lens, suggesting a focus on crisp zoom performance and flagship-level clarity.
The OnePlus 15s reportedly packs a massive 7000mAh battery, a significant leap for the brand and one that aligns with the industry’s recent focus on extended battery endurance for gaming, productivity, and multimedia. In addition to the battery upgrade, the smartphone could include an ultrasonic fingerprint sensor, premium metal frame, NFC support, and an IP69 durability rating for enhanced water and dust resistance, marking one of the highest protection standards for a mainstream smartphone.
The device is rumored to launch in India around June 2026, with pricing expected to align with the OnePlus 15 lineup. Meanwhile, the standard OnePlus 15 is confirmed to debut in India on November 13, becoming the first Snapdragon 8 Elite Gen 5-powered device in the country. With the S-series positioned for users seeking cutting-edge performance and longer battery life, the upcoming OnePlus 15s could reinforce OnePlus’ premium strategy in India.
