The number of cycles of mobile phone lithium-ion batteries is inseparable from the charging cycle. The so-called cyclic charging of lithium ion batteries is a complete charge and discharge cycle, so the number of cycles is actually a calculation method of the charge cycle. When the lithium ion battery reaches a complete charge cycle, the number of battery cycles will be +1.
One charging cycle means using up all the power of the lithium-ion battery, but it is not the same as charging once. For example, it uses only half of the electricity for several hours a day, and then it is fully charged. If you continue to do so the next day, this can only be counted as one charging cycle, not two. For example, if you use 20% for full charge today, you will count as one cycle if you use 80% next time. If you don't use it, you will count once. Anyway, if you use up 100%, you will count once.
The cycle of lithium-ion battery is calculated based on the cumulative value. For example, the nominal capacity of lithium-ion battery is one thousand milliampere hours. If it is charged once every 500 milliampere hours is used, such two times are counted as one cycle. After 300 cycles, the capacity began to drop significantly.
The number of cycles of lithium ion battery = the number of recharges. There is actually a big difference between the two. The number of cycles of lithium-ion batteries means that the mobile phone battery completes a complete charging cycle, that is, the complete charging and discharging process, the number of cycles is +1, and the number of charging is the number of charging of the mobile phone every time That is +1. There is a big difference in meaning between the two. The number of cycles of a lithium-ion battery does not mean the number of recharges.
Many people are afraid of lithium-ion batteries, but they are helpless. The frustration is because mobile phones, notebooks, tablets and other devices use it, and the fear is because I don’t know when the lithium-ion battery will suddenly make a terrorist attack in front of me: either burning or exploding. This kind of incident is naturally related to the electrical characteristics and quality of the lithium-ion battery itself, but it is not ruled out whether the lithium-ion battery is used correctly, and it is also one of the causes of the lithium-ion battery accident.
Lithium-ion battery mobile phones or chargers will automatically stop charging after the battery is fully charged, and there is no such thing as a trickle charge that lasts for more than 10 hours as a nickel battery charger. In other words, if your lithium-ion battery is fully charged, it is also white charged on the charger. And none of us can guarantee that the characteristics of the lithium-ion battery's charge-discharge protection circuit will never change and the quality will be foolproof. Therefore, the lithium-ion battery will be on the verge of danger for a long time. This is another reason for us to oppose long charging.
