Today's mobile phones are all lithium-ion batteries. Compared with nickel-cadmium batteries, the advantage of lithium-ion batteries is that they have no memory function and can be charged and used at any time.

Nickel-cadmium batteries have a memory function (memory charging times), and the life of nickel-cadmium batteries is related to the number of charging cycles (the number of charging cycles is limited), charging once will reduce some lifespan, so nickel-cadmium batteries must be fully charged and used up. , to maximize battery life.

Big Brother used nickel-cadmium batteries in the era, and modern mobile phones all use lithium-ion batteries. Because many people can't tell the difference between nickel-cadmium batteries and lithium-ion batteries, they apply the charging theory of nickel-cadmium batteries to lithium-ion batteries. caused confusion.
In addition, lithium-ion batteries are afraid of overcharging and overdischarging. 

Overcharging and overdischarging will cause the battery to age and reduce its lifespan, so there is no need to fully charge it and then use it, nor to recharge it when it is exhausted.

In addition, both the lithium battery end and the mobile phone end have dual protection of overcharge and overdischarge protection, so there is no need to worry about overcharge or overdischarge. In fact, the high temperature inside the mobile phone is the killer of the battery, and the high temperature can easily cause the battery to age and swell.

It is recommended not to use the phone while charging. That will do more damage to your phone's battery.
