Why people are using aluminium foil to keep their phones cool in summer; Does this simple hack really work?

Smartphones can overheat due to external heat sources and prolonged usage. Aluminium foil can act as a temporary heat shield by reflecting sunlight away. This method is most effective in outdoor or high-heat environments like car dashboards. However, completely wrapping the phone or covering ports should be avoided. Better cooling solutions include keeping the device in shade and closing unused applications.
