Why is nexus7 charging so slowly?

The following actions are recommended:

1. Stop charging test.

2. Change the charging position to eliminate the slow charging caused by intermittent contact of the socket.

3. If conditions permit, please replace the standby charger for testing. Or send it for repair and inspection.

4. When charging, if the mobile phone is equipped with a third-party plug-in such as a charging doctor, it is recommended to test it after unloading.

5. Check whether there are foreign objects, such as liquid, in the charging interface of the mobile phone, which leads to poor contact between the charging interface of the mobile phone and the charger and slow charging. If this is the case, it is recommended to send it for repair as soon as possible.

6. Back up mobile phone data (phone book, text messages, pictures, etc.). ) and restore the phone to factory settings (enter phone settings-reset-restore factory settings).
