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.
