[When should I start charging in normal use]

This can often be seen because the number of charge and discharge cycles is limited, so the battery power of the mobile phone should be recharged as much as possible. In fact, the life of the lithium battery has nothing to do with this. An experimental table on the charge and discharge cycle of a lithium ion battery can be exemplified below. The data on the cycle life are listed below:

Cycle life (10% DOD): >1000 times

Cycle life (100% DOD): >200 times

Among them, DOD is the abbreviation of depth of discharge.

As can be seen from the table, the number of chargeables is related to the depth of discharge, and the cycle life at 10% DOD is much longer than that of 100% DOD.

Of course, if it is converted to the actual total capacity of the charge: 10% * 1000 = 100, 100% * 200 = 200, the latter's full charge and discharge is still better, but the previous netizen's statement to do some corrections:


Under normal circumstances, you should have the reserve to charge according to the principle that the remaining battery power is used up and recharge, but if your battery is not likely to stick to the whole day on the 2nd day, you should start charging in time, of course, if Willing to carry the charger to the office is another matter.

The principle of recharging the remaining battery power is not to go to extremes. One of the more widely spread arguments like long charging is to "try to run out of battery power." This practice is actually only a nickel battery, the purpose is to avoid the memory effect, unfortunately it is also circulating on the lithium battery.

Someone has used the example of automatic shutdown since the warning of the low battery level of the mobile phone is still not used. As a result, the mobile phone in this example did not respond during the subsequent charging and booting, and had to be sent to the customer service for repair.

This is actually caused by the battery being over-discharged and the voltage is too low, so that it does not have normal charging and power-on conditions.

Personally recommend that the mobile phone lithium-ion battery should not be too full or use no electricity, the battery will not charge when it is used up, it will not cause damage to the battery, charging within 2-3 hours is appropriate, not necessarily full. However, the lithium battery should be fully charged (normal charging time) and discharged after 1 to 2 times every 3 to 4 months.

Lithium batteries that have not been used for a long time should be stored in a cool and dry place, in a semi-electric state (70--80% of full power, if your mobile phone displays 4 grids when fully charged, then 3 grids can be best). The storage of full power is dangerous and the battery will be damaged. If the battery is stored without electricity, it will be destroyed. Check every three to six months to see if you want to recharge.

Lithium-ion batteries can be divided into liquid lithium-ion batteries and polymer lithium-ion batteries according to the electrolyte. The electrolyte of the polymer lithium-ion battery is a colloid and does not flow, so there is no leakage problem and it is safer.
