Several common misconceptions about cell phone batteries | love to play with computers - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

I saw on the Internet that many friends' mobile phones were automatically turned off, and they couldn't sleep to turn on the phone. Some time ago Love to play computer games Some editors have encountered similar problems. So in view of this incident, I would like to tell you about this battery mistake!

First of all, the activation of lithium battery. Most people think that the charging time must exceed 12 hours. The battery can be activated only after repeated charging three times. This statement is obviously a continuation of nickel batteries (such as nickel cadmium and nickel hydrogen). So this is a misinformation.

Secondly, the battery life is related to the charging cycle, not the number of times of charging. Lithium batteries are said to have a "charging cycle", that is, when the total charging amount of several charges is 100%, a charging cycle can be counted.

Then it is better not to overcharge. Some people are used to charging all night at night, or after charging, they feel that they may not be fully charged, so they can charge for another two or three hours. In fact, it is totally unnecessary. After the battery is fully charged, the indicator light of the mobile phone will display the signal of full charge, at this time, the charging will automatically stop, and your overcharge is also a white charge! There is also a so-called "trickle" charge that lasts for more than 10 hours. After the lithium battery is fully charged, it will continue to charge. Although it usually stops charging automatically, it cannot guarantee that the battery charging protection circuit will not be accidental. If there is a problem with the charging protection circuit, it must be dangerous to overcharge the battery. Another is that when the battery is fully charged, it automatically stops charging. However, since the mobile phone is still on and continues to consume power, it will automatically start charging again when it consumes a little power. Such frequent discharge and charging cycles must have an impact on the life of the battery.

Next, another mistake is that the nickel battery used to be as clean as possible. It was automatically powered off and recharged when the phone was used. This is to avoid memory effects. This is also extended to the lithium battery, which is incorrect. The lithium battery does not need to be powered off automatically when the phone is used. This will cause the voltage to be too low due to the excessive discharge of the lithium battery, which will make the phone unable to start! Overcharge and overdischarge of lithium battery will cause great damage to lithium battery, especially overdischarge. The correct way is that the phone prompts that the battery must be charged if it is too low, about 15%! Try not to use the mobile phone when charging it, because it will burn seriously!

Finally, I don't use my mobile phone for a long time. After a period of time (about one or two months), even if I don't use my mobile phone, I need to flush it. A few times ago, I may think that the battery is not very durable, but after several times of repetition, the battery basically recovers. Another saying is that after a certain battery fails, you can use a newspaper to wrap it in the refrigerator and freeze it for two or three days, and then take it out for two days. The failed battery can be restored to use, but it is only a few. Not every battery can be restored!

Finally, let's make a summary: the simple point is that the current battery charging is more casual, and it can be charged and unplugged at the same time. It's not a big problem. It's better to charge the battery once a month with trickle charging. Many battery software also have tips! In addition, don't panic if the phone can't be started after the battery is used up completely. Generally, it can be started normally after charging. For those who can't be started normally, you can also press the volume+and the power on button at the same time for about ten seconds to start!
