OnePlus is reportedly preparing a compact powerhouse for 2026, with reports suggesting the company is developing a smaller-screen flagship device. The upcoming phone is expected to launch under the names OnePlus 15T and OnePlus 15s, depending on the region. Both models will succeed the OnePlus 13T and OnePlus 13s, which were introduced earlier this year.
The OnePlus 15T/15s is rumored to arrive in the first half of 2026, powered by Qualcomm’s Snapdragon 8 Elite Gen 5 chipset. It is said to feature a 6.31-inch display with 1.5K resolution, most likely using an LTPS panel. The design could include a flat screen with slim, symmetrical bezels and an in-display 3D ultrasonic fingerprint sensor for enhanced authentication speed.
Moreover, the device may come with IP68 certification for water and dust resistance, adding durability to its premium build. One of the most notable upgrades could be a 7,000 mAh battery, which would be impressive for a phone of this size and performance level.
Earlier rumors also suggested that the OnePlus 15T and 15s might feature a triple rear camera setup, indicating enhanced imaging capabilities. While OnePlus has yet to make anything official, these reports suggest the brand is refining its T-series strategy by focusing on compact designs that deliver flagship-level power.
