OnePlus has started teasing the OnePlus 15T in China. The compact powerhouse is expected to break cover in March in the country. Ahead of the expected launch, tipster Digital Chat Station has shared some key details about the device, hinting at new features and accessories that could differentiate it from previous models.
Ultra-thin magnetic cooling accessory revealed

According to Digital Chat Station, OnePlus is preparing an ultra-slim magnetic cooling accessory designed specifically for the OnePlus 15T. The accessory is said to have an average thickness of less than 1cm, which could make it significantly thinner than most existing magnetic coolers currently available. Images comparing it with earlier cooling accessories indicate a more compact design aimed at improving portability without adding too much bulk to the device.
The tipster also mentioned that native magnetic support may require certain compromises in internal space, particularly affecting battery size. Despite this, newer devices appear to be moving towards broader compatibility with magnetic accessories, including ecosystems similar to Appleās MagSafe. The upcoming cooler is also believed to lack an internal fan, suggesting a different cooling approach compared to conventional solutions.
OnePlus 15T specifications (rumored)
Leaks suggest that the OnePlus 15T will be positioned as a compact flagship, featuring a 6.32-inch OLED display with 1.5K resolution and a 165Hz refresh rate. It is expected to be powered by the Snapdragon 8 Elite Gen 5 chipset and may support wireless charging, a feature absent from its predecessor. Battery capacity is rumoured to fall between 7,000mAh and 7,500mAh with 100W wired charging support.
Camera details remain unconfirmed, though speculation points to either a 200-megapixel or 50-megapixel main camera paired with a 50-megapixel telephoto lens and a 50-megapixel front camera. It is said to lack an ultra-wide camera like the previous generation.
