OnePlus is hard at work on its next model, expected in China as the OnePlus 15T and internationally (here included) as the OnePlus 15s. Slated for the first half of 2026, the handset is at the centre of a fresh leak based on internal testing, pointing to a bold spec sheet that could well split opinion.
The king of long-lasting compacts?
The most striking detail in this leak is undoubtedly the battery. Despite its compact footprint, the OnePlus 15T/15s is tipped to carry a massive battery of around 7,500 mAh.
That is a colossal figure for a phone said to stick with a 6.31-inch screen. If it pans out, OnePlus could redefine battery-life standards for smaller devices. Fast charging is reportedly rated somewhere between 100W and 120W. On the flip side, to make room for that giant cell, the phone is said to drop wireless charging altogether.
165Hz display and maximum power
On the display front, OnePlus is said to make no compromises. The leak points to a 6.31-inch BOE X3 OLED panel with 1.5K resolution and a very high 165Hz refresh rate, ideal for gaming.
Under the bonnet, power is reportedly handled by the Snapdragon 8 Elite Gen 5, the most powerful chip around right now.
Cameras: a risky call
It is the camera section that springs the biggest surprise. The rear module is said to include:
- A main sensor: either a 50 MP Sony IMX906 or a 200 MP Samsung HP5.
- A telephoto: a 50 MP Samsung JN5 sensor.
Contrary to expectations, however, this leak claims the phone will not feature an ultra-wide sensor. A surprising omission for a device in this class in 2026, at a time when versatility is so often the deciding factor.
Conclusion
The OnePlus 15T/15s is shaping up to be an unusual device. With a record 7,500 mAh battery in a compact body and raw processing power to match, it could be a dream come true for gamers and heavy users. That said, the potential absence of an ultra-wide camera and wireless charging suggests OnePlus is ready to make radical trade-offs in the name of battery life. Whether these specifications, still at the internal testing stage, make it through to the final version remains to be seen. Ready to take the plunge?
