The battery of our phone does not appreciate the low temperatures of winter. It works by a chemical reaction that creates a flow of electrons. The colder it is, the slower this reaction. The cold also leads to an increase in resistance and therefore a decrease in tension. Result: the laptop thinks that the battery is discharged and it turns off!
Conversely, the battery does not like high heat either. It is therefore important not to forget your phone, in the middle of summer, in a car in full sun. “It’s very dangerous, the battery can explode, underlines Donald Schleich, researcher at the Nantes Institute of Materials with Ouest-France. The phone should never be exposed to more than 60°C. He adds: “Treat the battery like your body: away from excessive heat, away from extreme cold! »
