Will fast charging cause any damage to the battery? First of all, let’s start with the principle of mobile phone charging. The modern mobile phone charging process seems very simple, but nothing is as it seems. In the past, mobile phone charging was very simple and crude, and high voltage was applied directly to the battery. Transport, and now smartphones are truly smart and have power management functions. When there is no charger, the battery is equivalent to a power source and has the function of powering the mobile phone, so the fast charging power and battery loss are not too large. Big relationship. There is also the problem of charging while playing games mentioned above. When playing games, the phone is actually always in a state of high-speed discharge. At this time, the management module connected to the charger power supply begins to play a role. At this time, the charger does not necessarily They all act directly on the battery, but on the mobile phone, and the excess power is given to the battery. Will 40W fast charging reduce the battery life? It’s not too late to find out! Therefore, the battery is actually in a charging state at this time, not in a discharging state. If the battery is only in a charging state, there will not be a lot of loss while charging while playing with the phone. However, the above statements are all based on the use of the original charger. If you use a non-original charger, the situation will be different. If you use an ordinary charger, and the ordinary charger does not have a fast charging function, the charging speed of the mobile phone will be affected. It cannot keep up with the discharge speed at all and is relatively consumed relatively quickly. At this time, the battery will be in a working state of discharging and charging at the same time. This is undoubtedly an important reason for the reduction of battery life. This is probably why many businesses emphasize the importance of using original chargers. It is not because their own chargers have advantages and good quality, but because they are the most suitable chargers for their mobile phones and will not cause any damage to the battery. Extra loss. To sum up, fast charging above 40W will not have much impact on the battery. Even charging and playing games will cause big problems, but you should pay attention when playing games and watching short videos. Regarding the problem of overheating mobile phones, the salesperson told reporters that current chargers are equipped with small fans to facilitate heat dissipation. Generally, fires will not be caused by the heat generated by long charging times. Firefighters reminded the general public that during the charging process , should be kept away from flammable and explosive items, otherwise the heat generated during charging can easily cause accidents. In addition, if the charging time is too long, it may cause battery damage, charger short circuit and other problems.
