After the phone is fully charged, there is no need to immediately unplug the charger. Modern mobile phones use lithium-ion batteries, which have a protective circuit that automatically stops charging once fully charged, so there is no problem of overcharging the phone. At the same time, modern mobile phones also adopt intelligent charging technology, which can adaptively adjust the charging current and voltage according to the charging situation, protecting the health of the battery. Therefore, even when fully charged, it can maintain the charging state without affecting the battery life.
Of course, if you don't need to continue using your phone, you can unplug the charger to prevent it from consuming energy and wasting power for a long time. Meanwhile, prolonged use of the charger may also cause damage to the charger itself, so unplugging the charger after fully charging can also avoid excessive use of the charger.
In short, there is no need to unplug the charger immediately after the phone is fully charged, but there is also no need to keep the charger plugged in. It can be flexibly used according to personal needs.
