Will overcharging affect battery life?

Nowadays, the popularity of smart phones makes many people rely more and more on mobile phones, but nowadays, smart phones are becoming thinner and thinner, while the endurance of smart phones has become a problem. Large capacity batteries have become a very important selling point in the mobile phone market recently, but most of the mobile phone service in the market is still not as strong as in the functional phone era. Nowadays, many people need to charge their mobile phones every day, so the charging problem of mobile phones is still a matter of considerable concern to many consumers. Often many people charge their cell phones at night, but people do not know if overnight charging will have a negative impact on the cell phone. Let's analyze this problem.

First of all, we need to know that the smart phones on the market use lithium batteries, but all batteries have a certain life. According to the data measured by the evaluation agencies, the battery capacity of mobile phones generally decreases significantly after 300 to 400 charges and discharges. This charge and discharge standard is from 0% to 100% for a cycle, that is to say, mobile phones use half of the electricity to charge twice before it is considered as a cycle, this standard is calculated according to 100% of the electricity used up. It's not the public's understanding that charging once is a complete cycle.

Compared with the previous nickel-hydrogen batteries, lithium batteries do not have memory function. People can use the current mobile phone to recharge at will, not necessarily to use up the electricity in the mobile phone to recharge. The characteristics of recharge at will also make the current smart machine to achieve maximum endurance.

I don't know if you have the habit of using your cell phone during the day, and finally plugging it in before going to bed at night so that it can be charged until the next morning. But people do not know whether it is good for mobile phone batteries, just because it is convenient to do so.

I remember that there was a news report about the explosion and fire caused by the over charging of mobile phones before. In fact, you should be at ease now. Because of the lack of protection mechanism for early batteries, batteries in saturated state for a long time will indeed explode and ignite because of overheating. But now the development of mobile phones has been basically solved by all manufacturers. One of the most important measures is that the battery has been added to the power management chip. When the mobile phone is full of power, the battery will automatically cut off the power supply, so that there is no need to worry about the problem of overcharging the mobile phone.

So nowadays, it is seldom seen in the market that all kinds of hidden dangers occur because of battery charging. In addition to the battery protection mechanism mentioned here, smart phones are equipped with the same system power protection mechanism. When the mobile phone is full of electricity, the system will cut off the power charge just like the battery. In summary, because of the improvement of battery and the system protection of mobile phone, there is no need to worry about overcharging when using mobile phone. Long-term power connection will not have a greater impact on the life of mobile phone battery. However, according to the current situation of mobile phone use on the market, the battery will generally reach the aging standard in two years, and the current mobile phone manufacturers generally make mobile phone batteries into non-removable equipment, so the current mobile phone use and replacement cycle is generally about two years.

I would like to remind you here that after the mobile phone is full of electricity, try to pull out the power supply, long-term power connection for such items as mobile phones still has certain security risks. So what else do readers think about overcharging mobile phones?
