Extended data:

Generally, the charge and discharge times of lithium batteries can reach several hundred times, but there is a common misunderstanding here. It is not that you can calculate the charge and discharge times by plugging in the charging plug once, so the battery is not too fragile. The first charge and discharge process refers to the process of recharging the battery after it is used up, rather than plugging in the charger and then unplugging it 1 time.

The continuous deep charging and discharging of lithium-ion battery has an impact on the battery life, and hundreds of life data are also measured under such extreme conditions. Under the condition of daily shallow charge and discharge, the life of lithium-ion battery is actually quite long. So it also explains that some people keep good habits, and mobile phone batteries can last for several years.

Lithium batteries generally have safety protection circuits and various safety devices to ensure that the circuits will be automatically cut off when the batteries are overcharged, discharged or short-circuited, so unless there are quality problems, the batteries will not have problems due to long-term charging.
