Charging socket is oxidized

The next reason why the phonedischarged by charging - this is an oxidized connector for the charger. The reason is primarily the ingress of moisture into the charging socket, for example, through wet hands or rain, perhaps the water spilled next to the phone and got on the contacts.

Signs that the phone has oxidized the jack for the charger are as follows:

  • The charger is connected.
  • An indicator is displayed on the screen that the charging is in progress.
  • After a while, the battery charge did not increase, but on the contrary, it decreased.
  • The phone is noticeably warm in the area of ​​the charging socket.
  • The charger plug is hot.
  • At visual inspection on contacts and the nest there is an extraneous characteristic plaque.

By the way, oxidized can be not only a connector on the phone itself, but also a plug of the charger, so this must also be taken into account.


There are several ways to remove the oxide from the charger connector, but they can be divided into two groups - temporary assistance and a 100% solution.


Temporary means the cleaning of contactsfrom oxide alone. Temporary it is called because the oxide sooner or later will appear again, and the procedure will have to be done anew. In addition, this method does not guarantee 100% success.

For cleaning, a very thin needle orany other sharp object, a small piece of cloth and soda. At the tip of the needle, you need to fix the fabric in such a way that it does not slip off and crawl into the connector. After that, you need to wet the cloth a little, dab it into soda powder, place it in the charging socket and clean everything as much as possible.


Since the effectiveness of the first method is notis too high, and the problem itself is not eliminated by 100%, then the only true way is to replace the socket. You can do it through the workshop or on your own.
