The fundamental reason for the explosion of a mobile phone is a short circuit in the battery. The vast majority of phone explosions are caused by battery explosions. During charging. The internal resistance of the battery is small, and the current generated instantly after connecting the power is too high, causing a short circuit in the power supply and causing the battery temperature to overheat and explode. So is it related to the charger? Many people have always believed that the explosion of mobile phones is closely related to the use of non original third-party chargers, but the fact is that only when you use cheap and uncertified chargers will there be significant safety hazards. And regular chargers are generally safe.
Why? The reason for the explosion of a mobile phone is that the temperature is too high for a short period of time, and the lithium battery burns, leading to the explosion of the phone. A regular 5V charger with low power cannot release too much energy during charging. Although fast charging chargers nowadays have high power, due to their short charging time and the fact that the temperature has not yet risen, charging has already ended, so it will not cause any safety hazards. So the explosion of mobile phones should not be carried by the charger.
But everyone doesn't have to worry too much. Under normal use, the probability of a phone exploding is still very small, because most phone battery manufacturers install management chips in the battery, a protective circuit, to deal with unexpected accidents. When there is a problem with the battery, the protection circuit will immediately turn off the battery. Therefore, the explosion of mobile phones is often due to issues with the quality and design of the phone or battery. It has little to do with the charger.
