OnePlus 15T Coming with Ultra-Thin Magnetic Cooling Accessory

Fresh details about the upcoming OnePlus 15T have started to surface, and it’s shaping up to be a compact flagship with some unusual hardware tricks. While OnePlus has already confirmed the phone is coming soon, an exact launch date is still under wraps. Meanwhile, the first details are starting to spread about this new compact flagship. Today, we have a rather intriguing leak.

According to well-known tipster Digital Chat Station, the OnePlus 15T may support magnetic wireless charging, with compatibility extending to Apple’s magnetic charging ecosystem. Okay, that's nice and seems to be starting to become a trend when even the Galaxy S26 Ultra decided to adopt it. If accurate, this would mark a notable shift for OnePlus, potentially opening the door to a wider range of magnetic accessories.

However, the most interesting bit in this rumor points to a magnetically attachable external cooling fan, reportedly just 1cm thick. The accessory is said to snap onto the back of the device and help manage thermals during heavy workloads like gaming or sustained performance tasks. Cooling accessories have been common these days for mobile gaming enthusiasts. It's pretty easy to find some that work with a dedicated battery or via the USB-C port. OnePlus's approach could be an interesting one. We are curious to know if the phone will be powering it via magnets, or whether the cooler will be using it only to attach to the device.

On the hardware side, the OnePlus 15T will carry Qualcomm’s Snapdragon 8 Elite Gen 5 chipset, positioning it firmly in flagship territory despite its compact form factor.

Leaks suggest the phone could feature a 6.32-inch display and a dual rear camera setup. The Battery capacity is rumored to be unusually large for a smaller phone, possibly ranging between 7,000mAh and 8,000mAh, alongside support for 100W wired charging. This probably will be the perfect phone for those who want a compact device but don't want to sacrifice battery capacity or raw power.

If the current timeline holds, the OnePlus 15T is likely to make its official debut in March, potentially arriving as a rare “compact powerhouse” in a market dominated by larger flagships.
