The phone USES a lithium-ion battery, which has no memory effect and can be filled in 2-3 hours. If the first three charges of a new battery can reach up to 12 hours or more, that can cause a lot of damage to the battery, potentially causing the battery to swell and even burn. Thanks to the phone and charger, there are protective circuits, which are automatically cut off when charged to 100%, and will not be charged on the charger. However, it is better to remove the charger so that the battery can be overcharged in case of a problem with the charger, which can cause serious damage to the battery material and affect the battery's capacity and life.
