When the plug is plugged into an outlet but the phone doesn't charge, there can be several reasons. First, check that the plugs and sockets are intact and not loose or broken. Secondly, confirm whether the charger and data cable used are compatible with the phone and are of reliable quality. In addition, check whether the charging port of the phone is blocked by dust or debris, which may affect the charging effect. If none of the above is a problem, then there may be a fault inside the phone, such as a damaged battery or a problem with the charging circuit. At this time, it is recommended to contact the mobile phone after-sales or professional maintenance personnel for inspection and repair. In short, when the phone can not be charged, do not panic, to investigate the possible causes one by one, and take appropriate measures to solve the problem. At the same time, in order to avoid similar problems, it is recommended to pay attention to protection when using the charger and data cable to avoid excessive pulling or falling.
The plug must be in bad contact with the socket, so it can't be charged.
The socket may be broken, or the phone charging port connector is broken.
