Europe’s heatwave has an important lesson for smartphone users across the world

Europe’s severe heatwave causes smartphones to overheat, leading some to place them in fridges. Experts caution this practice creates internal moisture damage and can harm devices. Swollen batteries and non-functional phones are common after this cooling attempt. Users should keep phones out of direct sunlight and avoid intensive apps. Turning off features like Bluetooth and GPS can also help prevent overheating.
