Those who read the news at ordinary times should have read the news about the phone explosion. Some may just break the phone, and some may even have their hands injured by the explosion, or even died because of the phone explosion.

Mobile phones are already a part of our daily life. Most people will feel insecure without mobile phones, which makes people feel very uncomfortable. You can go out without your wallet but not without your mobile phone. If mobile phones are so dangerous, then don't we carry a bomb every day? Is it really so dangerous?

In fact, the cell phone battery is not as dangerous as we thought. Have you seen the cell phone battery of your friends around explode? In fact, the probability of cell phone battery explosion is very low. The explosion is mostly caused by short circuit, but generally there is a protective circuit in the cell phone battery, so don't mention the instantaneous short circuit, even if it is a long-term short circuit, the battery will not be dangerous. In case of short circuit, with the help of the protection circuit, the voltage at both ends of the board will be 0.

But it does not mean that the protection circuit is invincible. Generally, it is OK to protect the circuit below 5V, but if the charging voltage becomes higher, it is difficult to say whether the protection circuit can still take effect. Another thing to note is that do not put your mobile phone in a place where it is hot and not easy to dissipate heat. Some people like to put their mobile phone in the bed before sleeping, which is also unsafe.

In general, the battery is difficult to be dangerous, unless you remove the protection circuit, or charge it at a relatively high voltage. The explosion is more likely due to the use of substandard batteries or the use of high voltage chargers. So if your phone is not a fake phone and the battery charger you use is not original, you don't need to worry about the explosion of your phone battery. The probability of explosion is lower than the probability of winning the lottery.
