Quite often, mobile device users are faced with one not very pleasant problem - the phone discharges on a charge. The reasons for this can be completely different, as well as ways to eliminate them. In this article, we will try to consider all possible options for why the phone discharges when charging, and how to deal with it.
Bad Charging Socket
The most common reason a phone discharges while charging is because of a faulty charging socket. A similar situation develops quite often, especially with unstable voltage or factory marriage. "Symptoms" are standard:
- Charger connected.
- An indicator is displayed on the phone that charging is in progress or there are no indications at all.
- After some time, the phone does not gain charge, but rather spends the rest.
And although some of the described "symptoms" will be encountered more than once in the course of the article, in this case everything points to a faulty charging socket. To finally make sure that the socket is broken, you need to try connecting the phone to another outlet, changing the charger to eliminate its malfunction. If nothing has changed, you can proceed to repair.
Elimination
In order to fix a faulty charging socket, you can go to a service center, but only if the phone is under warranty. There they should accept it without any problems and repair it within a few days, although it all depends on the service center itself.
If your phone has already run out of warranty, contact any well-tested mobile phone repair shop. The repair time is usually much less than in a service center, and the quality of work is about the same.
Another option is to change everything yourself. This method is suitable only for those who are well versed in soldering and have the necessary equipment.
Charging Socket Oxidized
The next reason why the phone discharges on charging is the 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 water spilled near the phone and got on the contacts. Another reason for oxidation can be a banal and bad habit of taking a smartphone with you to the bathroom. This is not recommended, because the bathroom is a room with high humidity. The exception is only those phones that have moisture protection.
The signs that the charger socket is oxidized on the phone are as follows:
- Charger connected.
- An indicator that the charge is in progress is displayed on the screen.
- After some time, the battery charge did not increase, but rather decreased.
- The phone has noticeably warmed up in the area of the charging socket.
- The charger plug is hot.
- During visual inspection, there is an extraneous characteristic plaque on the contacts and the nest itself.
By the way, not only the connector on the phone itself can be oxidized, but also the plug of the charger, so this also needs to be taken into account.
Elimination
There are several ways to eliminate oxide from the charger connector , but you can divide them into two groups - temporary assistance and a 100% solution.
Temporary
A temporary method involves cleaning the contacts of oxide on their own. It is called temporary because the oxide will appear again sooner or later, and the procedure will have to be repeated. In addition, this method does not guarantee 100% success.
For cleaning you will need a very thin needle or any other sharp object, a small piece of cloth and soda. At the tip of the needle, you need to fix the fabric so that it does not slip and crawl into the connector. After that, you need to slightly wet the rag, dip it in soda powder, place it in the charging socket and clean everything to the maximum.
Replacement
Since the efficiency of the first method is not too high, and the problem itself is not 100% resolved, the only correct way is to replace the socket. This can be done through the workshop or on your own.
Bad Charger
Another reason why the phone is charging and discharging is a commonplace malfunction of the charger itself. The fact is that only one wiring somewhere inside the cable breaks enough - and that's it, a full charge will not come. There is no point in describing the symptoms here; just check the charging on another phone or connect your phone to a working charger.
Elimination
This problem is fixed quickly and easily, just buy a new USB-cable or completely change the charger.
Burnt board
A burned-out card with a socket is the reason why the phone discharges during charging. In this case, the socket itself may be serviceable, but the board on which it is installed sometimes burns out or fails. With such a breakdown, the charging indicator does not appear, however, if the corresponding icon still appears, the phone will simply be discharged.
Elimination
This damage can be eliminated only by a complete replacement of the circuit together with the charging socket. You can do this in any service or on your own.
Quick discharge
Often there is such a problem that after charging the phone discharges, and quite quickly, within an hour or a little more. The main and only reason for this is a faulty battery, which has exhausted its entire resource.
Elimination
This breakdown is fixed quickly, you can not give the phone to the service - you only need a new battery for the phone of the corresponding model.
