When should you start charging during normal use
In our forum, you can often see this argument, because the number of charge and discharge is limited, so the phone battery should be used up as much as possible before charging. However, I found an experimental table on the charge and discharge cycle of lithium-ion batteries, and the data on the cycle life are listed as follows:
Cycle life (10%DOD):>1000 times
Cycle life (100%DOD):>200 cycles
DOD is the abbreviation of discharge depth. It can be seen from the table that the number of recharges is related to the depth of discharge, and the cycle life of 10%DOD is much longer than that of 100%DOD. Of course, if it is converted to the relative total capacity of the actual charge: 10%*1000=100, 100%*200=200, the full charge and discharge of the latter is still better, but the previous user's statement needs to make some amendments: Under normal circumstances, you should have reservations in accordance with the principle of recharging the remaining battery power, but if your battery is not expected to last the whole day on the second day, you should start charging in time, of course, if you are willing to carry the charger to the office is another matter.
And when you need to charge for an upcoming important event that is expected to cause busy communications, even when the battery has a lot of power left, then you only need to charge ahead of time, because you have not really lost "1" charge cycle life, that is, "0.x" cycles, and often this x will be small.
The principle of recharging when the remaining battery is used up is not to go to extremes. There is a saying that is as popular as long charging, that is, "try to use up the battery power of the phone, and it is best to use the automatic shutdown." This practice is actually only on the nickel battery, the purpose is to avoid the memory effect, and unfortunately it is also spread on the lithium battery today. There have been cases of automatic shutdown after the warning that the battery of a mobile phone is too low, but it still does not charge and continues to be used. As a result, the phone in this example did not respond to later charging and startup, and had to be sent to customer service for overhaul. This is actually due to the battery due to excessive discharge caused by the voltage is too low, so that it does not have normal charging and boot conditions caused by.
