2. Place The Phone on a Hard Surface
Just like laptop and other similar electronics devices, keeping them on a soft surface like bed, rug or sofa while charging makes them absorb heat thereby causing overheating but when you keep them on a smooth hard surface like table, air will be going out and entering without much restrictions.
3. Avoid Over Charging
