On the service life of mobile phone lithium battery ..

1, you can't overcharge, you can't charge when fully charged, and recharging will affect the life of lithium batteries and even explode! Even lithium batteries are protected by charging circuits. It's better to charge it to 80%, not to fill it. Fully charged will also affect battery life!

2, can't overdischarge, charge before there is no electricity! There is about 20% left to recharge!

3, charging time depends, generally only one hour, if less than 80% for a period of time!

4, 3 months or so to do a full discharge of Wally, that is, shut down, fully charged 100%, which is conducive to the maintenance of lithium batteries. Don't do this! Personally, I am lazy. If I remember, I will do it. If I don't remember, forget it. A battery doesn't have to be so serious!

5. To sum up, we can draw the slogan of the inventor of lithium battery: charge with use, charge with use! It means that even if the battery is still 30%-60%, or even 70%, it can be charged without damaging the battery. The life of lithium battery is about three years, even if it is useless for three years, it is brand new, and its performance will be greatly reduced in the third year.

Precautions:

First of all, because there is almost no memory effect, lithium batteries can basically be charged at any time. Friends who use laptops should know that lithium batteries are usually charged at 90%, and because there is almost no memory effect, they are designed according to the idea of maintaining the maximum available time.

Secondly, complete discharge of the battery is harmful to the battery. The mobile phone is in normal use, and it is turned off without power. At this time, the voltage is the cut-off voltage, so you need to charge.

The service life of a lithium battery should be calculated by the total rechargeable capacity, that is, how much energy you have charged in this battery in your life. But the battery will age, and the change is nonlinear.
