If your phone does not charge, do not rush to carry it into repair. You may be able to solve the problem yourself. The reasons why charging is not carried out can be different.
1
The simplest reason is the absence of electricity. Try to turn on the light or other electrical appliances: if there is no electricity, you will have to wait until it turns on.
2
The reason can serve as bad contact between the connector and the plug. This may be due to contamination of contacts, as well as the fact that the nest is loosened due to non-accurate treatment of equipment. Clean the contacts are quite simple. Remove the battery from the phone, moisten the bandage in pure alcohol (solvents and other active substances cannot be used), wipe the charges of the charger.
3
Often, problems arise due to twisting and excerpts of the wire. If it is possible, check the charger on another phone. With a multimeter, you can measure the voltage. If it is not, then the problem is found (the charger is guilty) if the voltage is present - the reason lies in the phone.
4
As for the phone, first of all, you should inspect the contacts of the battery and the phone itself to which it connects. They can be gently wipe. Each battery is designed for a specific number of charging cycles. Gradually, the energy that it accumulates from the network becomes less. If the battery has exhausted all its resources, it should be replaced. The battery malfunction may indicate it, but maybe such that it looks quite normal, but is not working.
5
If you changed the battery, and the phone is still not charging, the controller can be broken (it is he responsible for charging). Then you have to disassemble the phone and change the controller. Of course, it is better to contact the service center.
If the phone does not charge, and you do not understand anything in digital electronics, you should not disassemble it yourself. Just inspect the contacts and wipe them. If the problem did not decide - trust the repair of the phone to professionals.
