The OnePlus 15T is rumored for a mid-to-late March 2026 launch, arriving months earlier than its predecessor. Leaker Digital Chat Station claims the device will run on the Snapdragon 8 Elite Gen 5 chipset. This follows the OnePlus 13T, which debuted in April 2025, suggesting a strategic shift in the brand's release calendar.

Previous leaks hint at a 6.31-inch '1.5K' display with a 165Hz refresh rate, up to 16GB of RAM and 1TB of storage, and a substantial 7,000 mAh battery. It's also expected to support wireless charging and carry an IP68 rating. However, reports indicate no camera upgrades are planned, focusing instead on internal performance and battery life.

This accelerated schedule could position OnePlus to compete more directly with Samsung's Galaxy S series and Google's Pixel lineup in the first quarter. A March launch would allow the company to capture early-year sales momentum before the summer season. The move signals a more aggressive product cycle for the brand's T-series flagships.
