OnePlus 15s/15T's flagship chipset leaks, big battery too

According to a new rumor from the prolific Digital Chat Station over on Weibo, OnePlus is working on a smaller-screen device with a flagship chipset. This is likely to be branded OnePlus 15T and OnePlus 15s, depending on market, and will be the successor to the 13T and 13s, which both launched earlier this year.

The 15T/15s is expected to arrive in the first half of 2026 with the Snapdragon 8 Elite Gen 5 SoC on board. Its screen will be 6.31" with "1.5K" resolution, most likely LTPS, flat, with symmetrical small bezels on all sides, and an embedded 3D ultrasonic fingerprint sensor.

The device should also be IP68 certified for dust and water resistance, and its battery capacity will be around 7,000 mAh, which is quite a feat for a handset of this size. A previous rumor mentioned that the 15T/15s is also getting a third camera on the back.
