This is all kinds of messed up, a cooling solution for a phone that runs too hot, that adds more bulk and weight, and draws juice from the device battery.
That it's needed at all in the first place is the issue.
OnePlus will unveil the Ice Card Mini magnetic cooler alongside the OnePlus 16 on October 12. The 50g accessory measures 70mm by 53.4mm, pairs a TEC cooling chip with an air-cooling system and can be powered directly by the phone over USB-C. It follows the 68g Magnetic Ice Cooling Clip, which launched in March.
