　　Point 1: Is fast charging safe?

　　Nowadays, many mobile phones are equipped with fast charging technology, small ones are 18w, large ones are even more than 40w, which greatly improves the charging speed of our mobile phones and no longer needs to wait for a long time. The phone can only be played when the battery is fully charged. It is really good to have such an experience of charging faster than before. In fact, there are still many users who think that fast charging technology is not safe. In fact, there is no need to worry about this, because a mobile phone needs to conduct special research on the fast charging technology, and the required Things are very strictly controlled, and there is also an intelligent battery management system in the mobile phone, which allows the mobile phone to automatically turn on a smart charging protection according to the charging conditions of the mobile phone, which means that in our fast charging When the time comes, the phone will automatically protect itself, and there is no need to worry about the safety of the fast charging technology. However, we need to pay attention to the fact that many users like to buy some random chargers to use when the charger is broken. The price is cheaper, but it has hidden safety risks, so be sure to choose regular and original chargers. , the price is a bit more expensive, but it can ensure the safety of our charging.

　　Second point: Is fast charging harmful to mobile phone batteries?

　　Many users are worried about the life of mobile phone batteries, because once the battery is affected, the battery life of our mobile phones will be affected, and it may even cause our mobile phones to freeze. In fact, battery damage mainly comes from two aspects. The first aspect is that the current is too large, and the thermal effect of the current is too high, which will cause the phone to heat up very seriously, thus causing the battery of the phone to be damaged. The other aspect is the cathode of the battery. The anode and anode will continue to shrink or expand with the release of ions, which can easily damage the chemicals on the battery and shorten the life of the battery. Just looking at the principle, we can easily see that fast charging will damage the battery usage. However, the current mobile phone fast charging technology can control the charging wattage by itself. When our mobile phone is in use, the charging power is not the maximum power. It will be controlled at a wattage that does not cause the phone to heat up so seriously. Only when When the mobile phone is not in use, the charging power is the highest, so there will be no safety problems, but the damage to the battery will be certain, but this is a problem that exists in all mobile phones, but these are all in the country Under the standard, as long as the health of the battery can be maintained above 80% after 500 charging times, then this is within a reasonable range, and most mobile phones still remain within this range. , so actually we don’t have to worry too much.

　　Summary: Fast charging itself is safe, but it will also have an impact on mobile phone batteries, but the impact is relatively small and within a reasonable range, so you don’t have to worry too much about the safety of fast charging when using your mobile phone. In fact, many users now change their mobile phones very quickly. When they change their mobile phones, the battery life is still very long, so there is really no need to care too much about the battery life. What do you think?
