Causes:
1. It is normal for the circuit components to produce a faint sound during the charging process.
2. The socket, charger, or phone is abnormal.
Scenarios & Solutions:
Scenario 1: a weak sound near the adapter/charger
Solution: When the circuit components in the charger transform and rectify the charging current, there may be a weak current sound, which is a normal phenomenon. realme charging technology has multiple protections from the adapter to the charging port to the phone. It has passed through the safety certification. Please use it with confidence.
Scenario 2: The sound is obvious during charging
Solution: You can try to plug in other sockets and use other adapters, or phones to try again. If it is normal on other sockets, it may be caused by your socket; if the problem still exists, or has affected your normal use, please back up your data and go to the nearest realme customer service center for testing.
