When is it better to charge lithium batteries during normal use?

This is often seen in our forum, because the number of charge and discharge is limited, so the power of the cell phone battery should be recharged as much as possible. But I found an experimental table on the charge and discharge cycle of lithium-ion batteries. The data on the cycle life are listed below:

Cycle life(10 % DOD): 1000 times

Cycle life(100 % DOD): 200 times

The DOD is an English abbreviation for discharge depth. From the table, it can be seen that the number of rechargeable times is related to the discharge depth, and the cycle life of 10 % of the DOD is much longer than that of 100 % of the DOD. Of course, if the relative total capacity of the actual charging is: 10 % * 1000 = 100, 100 % * 200 = 200, the latter's full charge discharge is still better, but the previous Netizen's statement needs to make some corrections: Under normal circumstances, You should recharge your battery on a reserved basis, but if your battery starts charging in time for the next day when you expect it will not last the whole day, Of course, if you're willing to go to the office with a charger on your back.

And when you need to recharge to cope with an important event that is expected to lead to busy communication, even when the battery has a lot of power, then you just charge in advance because you don't really lose "1" charge cycle life. That is, "0.x" times, and often this X will be small. The principle of recharging the battery after it's used up is not to go to extremes. A saying that is as widespread as long charging is that "try to use up the battery of the mobile phone, and it is best to use automatic shutdown."

This practice is actually just a nickel battery practice. The purpose is to avoid the memory effect. Unfortunately, it is also circulating on lithium batteries. Some people have used the example of automatic shutdown because they still do not charge after the warning that the battery battery is too low. As a result, the mobile phone in this example did not respond to the later charging and booting, and had to send customer service maintenance. This is actually because the battery is too low due to excessive discharge, so that it does not have normal charging and boot conditions.
