How should the new lithium-ion battery be charged?

Regarding the activation of lithium-ion batteries, many claims are: the charging time must be more than 12 hours, repeated three times in order to activate the battery. This statement that the first three charges should be charged for more than 12 hours is obviously a continuation of the statement that nickel batteries (such as nickel-cadmium and nickel-metal hydride). So this statement can be said to be misinformation at the beginning. The charging and discharging characteristics of lithium-ion batteries and nickel batteries are very different, and I can tell you very clearly that all the serious official technical materials I have consulted emphasize that overcharge and overdischarge will affect lithium-ion batteries, especially Liquid lithium-ion batteries cause huge damage. Therefore, it is best to charge according to the standard time and standard method, especially not to charge more than 12 hours. Generally, the charging method described in the mobile phone manual is the standard charging method suitable for the mobile phone. In addition, 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 battery's charge and discharge protection circuit will never change and the quality will be foolproof, so your battery will be on the verge of danger for a long time. This is another reason why we oppose long charging. In addition, on some mobile phones, after charging for a certain period of time, if the charger is not removed, the system will not only stop charging at this time, but also start a discharge-charge cycle. Perhaps the manufacturer of this approach has its own purpose, but it is clearly detrimental to the life of the battery and mobile phone/charger. At the same time, long-term charging takes a long time, often at night. According to the situation of my country's power grid, the voltage at night in many places is relatively high and fluctuates greatly. As mentioned earlier, lithium-ion batteries are very delicate, and their ability to withstand fluctuations in charging and discharging is much worse than that of nickel batteries, so this brings additional dangers.
