Technical reports warn of the dangers of leaving phones and electronic devices inside cars exposed to direct sunlight, stressing that the significant rise in temperatures threatens the safety of batteries and internal components, and negatively affects the efficiency and lifespan of devices.
Lithium-ion batteries are the most vulnerable to damage, as high temperatures lead to a decline in their efficiency or complete damage. Smartphones often respond to these conditions by lowering the screen brightness or automatically stopping charging as a self-protection mechanism. These risks are not limited to phones only, but extend to laptops, wireless headphones, and power banks, even if they are turned off or stored inside bags.
In the same context, experts recommend avoiding leaving electronic devices inside vehicles in hot climates. If the device has already become overheated, it must be disconnected from charging immediately, and left to cool gradually in a shaded, well-ventilated place, while warning against exposing it to sudden cooling methods that may exacerbate damage.
