Phone charging is interrupted – why and what to do?

What to do if the phone starts charging and stops by itself?

The charging process can be interrupted due to phone crashes, battery failure, problems with the charger, and for some other reasons. Many of the problems can be fixed on your own at home, others will require the intervention of specialists.

If the phone is connected to the charger and first charges and then stops, the problem may be either with the charger itself or with the phone. You need to try several options to find the cause of the problem.

Entrance dirty

Charging can be hindered by dust particles and debris, which eventually clogs into the phone’s connector. The port must be cleaned with a thin stick (preferably non-sharp) or with a can of compressed air. In this case, cleaning must be carried out very carefully so as not to damage the entrance.

Loose phone jack

During charging, you need to check whether the cable fits snugly into the connector on the smartphone. If it wobbles, comes off, or is too easy to insert, the mobile device port may be the cause. You can verify this by inserting another memory into the connector. If the second cable is not inserted tightly, then the connector is loose .

Damaged cable

Charging may be interrupted if the cable insulation is damaged. It is necessary to check the entire length of the cord for breaks, cracks and places where the wiring sticks out. If there are such places, then they must be wrapped with electrical tape, but it is better and safer to replace the cable with a new one.

Connector latches burned out

The microUSB cable is attached to the connector using special “teeth” on the underside of the plug. Over time, they can fall back, although in the normal state (not charging) they should be raised. You can return them to their normal position yourself by prying the latches with a needle. In this case, the charging must be de-energized.

Damaged contacts in the phone or cable connector

The pins inside a phone or cable jack may also change position. Initially, they should be curved, but over time they straighten out and cease to be in close contact with each other. Because of this, the charging process may be interrupted. As with the retainer, the contacts can be straightened with a pin or needle. However, this must be done carefully so as not to damage the connector even more. When straightening the contacts on the phone, the device must first be turned off and the battery removed (if possible).

Faulty power controller

The power controller may fail, causing the phone to either incorrectly display the battery level or to interrupt charging. However, it is possible to understand that the problem is in the controller only after diagnostics in the service center.

Battery problem

Battery life is limited to a certain number of charge-discharge cycles. After that, the user may start experiencing problems, for example:

• The phone will start to land faster.
• The phone will turn off even though the battery level is still high.
• Charging may interrupt itself.

If the battery on your phone has lasted more than 2-3 years, it may need to be replaced . At the same time, it is important to ensure that the battery is not swollen , as this is a sure sign of its malfunction.

Failures in system update

Some users have noted that charging has started intermittent after a phone system update. However, the problem was solved by itself when the next update came out. In this case, there are two solutions:

• Wait for the new update, which will fix the problems of the previous version.
• Roll back the system to a previous update.

Power adapter failure

If the power adapter (charging unit) gets very hot during charging, and the charging itself is interrupted, the problem may be in it. It is recommended to connect another unit and check if the problem is fixed.

What should I do if my phone stops charging?

By analyzing all the possible causes of charging problems, we can draw conclusions on how to fix them. In order for the phone to start charging normally, the user needs to:

• Clear the phone connector from debris.
• Replace the charger with another one. This will immediately eliminate problems with the cable, connector latches, contacts, charging block and loose phone port. If another cable charges the phone normally, then the problem was in the memory.

It is not necessary to buy a new charger to test. It is enough to go to any hardware store and ask to check the phone with a different cable. In most cases, a potential buyer will not be refused.

• Install a software update or roll it back to a previous version.
• Carry out diagnostics of the phone in the service center. So you can understand if there is a problem with the battery, power controller or other parts of the mobile device.
• Reset phone to factory settings . If none of the reasons fit, then the matter is in the internal failure of the device. A factory reset may help.
