When a smartphone tends to overheat, it’s sometimes because of the battery. Especially if your smartphone already has a few kilometers on the odometer. A fact to check from time to time, even if it is true that manufacturers have made great progress in terms of cooling in recent years. But if your mobile is a little dated, be careful.
