The number of cycles and charging cycle of lithium-ion batteries for mobile phones are closely related. The so-called lithium-ion battery cycle charging refers to a complete charging and discharging cycle, so the number of cycles is actually a calculation method of the charging cycle. When the lithium-ion battery reaches a complete charging cycle, the number of battery cycles will increase by 1.

One charging cycle means using up all the power of a lithium-ion battery, but it is not equivalent to charging it once. For example, using only half of the battery for several hours a day and then fully charging it. If you continue like this the next day, it can only be counted as one charging cycle, not two. For example, if you use 20% today and need to use 80% next time, it counts as one cycle. If you don't use it anywhere, it counts as one cycle. Anyway, if you use 100%, it counts as one cycle.

The cycle of lithium-ion batteries is calculated based on cumulative values. For example, if a lithium-ion battery has a nominal capacity of one thousand milliampere hours and is charged every 500 milliampere hours, then two cycles are counted as one cycle. Typically, after 300 cycles of charging and discharging, the capacity of lithium-ion batteries begins to significantly decrease.

Lithium ion battery cycle times=charging times. There is actually a big difference between the two. The number of cycles for lithium-ion batteries refers to the complete charging and discharging process of a mobile phone battery, and the number of cycles is+1, while the number of charges is+1 each time the mobile phone completes one charge. There is a significant difference in meaning between the two, as the number of cycles of a lithium-ion battery does not necessarily represent the number of charges.

Many people have a sense of fear towards lithium-ion batteries, but they are also helpless. Helpless because mobile phones, laptops, tablets and other devices all use it, fearful because they don't know when a lithium-ion battery will suddenly perform a terrorist attack in front of them: either burning or exploding. This kind of event is naturally related to the electrical characteristics and quality of lithium-ion batteries themselves, but it cannot be ruled out that the correct use of lithium-ion batteries is also one of the reasons for lithium-ion battery accidents.

Lithium ion battery phones or chargers will automatically stop charging after the battery is fully charged, and there is no so-called trickle charging that lasts for more than 10 hours with nickel chargers. That is to say, if your lithium-ion battery is fully charged and placed on a charger, it will still be charged for nothing. And none of us can guarantee that the characteristics of the charging and discharging protection circuit of lithium-ion batteries will never change and the quality will be foolproof, so lithium-ion batteries will be hovering on the edge of danger for a long time, which is another reason why we oppose long charging.
