Why can't the cell phone be charged?

Smart phones have now become an indispensable part of people's life. Especially in China, you can leave your wallet and keys when you go out, but you must not forget to bring your mobile phone. But sometimes the mobile phone s can't be charged. What's going on? Today, let's share the common reasons why mobile phones can't be recharged.

First of all, we should eliminate the causes of the mobile phone itself. For example, replace the data cable, the charging head and socket, and reconnect it.

When the problem is still not solved by shutdown and restart and system update, we should check the problem of the mobile phone itself.

1. Check whether there is dust at the interface

Because the mobile phone is exposed to the outside for a long time, there will be a lot of dust accumulation at the interface, resulting in poor contact between the interface and the power line. At this time, you can wipe it with alcohol and cotton.

2. The internal parts of the mobile phone are damaged

If the mobile phone has been dropped before, resulting in the disconnection of the original motherboard, it is necessary to replace the power IC. As the service life is long, the interface is not firm, which is also an important reason why it can not be charged.

3. The battery is completely damaged

Generally speaking, it is normal that the battery health is about 75% after the mobile phone has been used for two years. However, if our mobile phone can't be charged after only two or three years, it must be that we don't charge the mobile phone correctly. What bad charging habits will shorten the service life of the mobile phone battery?

1) Don't wait until the phone is turned off to power the phone. Generally, when the remaining 10% - 20% power is prompted, you should plug in the power in time.

2) Don't overcharge. The current fast charging can basically fill the battery in about an hour. You should unplug it in time. If you let the mobile phone charge all night, the battery will be damaged in the long run.

         3) Don't play mobile phones while charging, especially minors like to play mobile games. They often play while charging for several hours, which leads to the fever of mobile phones and serious potential safety hazards.

The above is related to the charging failure of the mobile phone. It is recommended that you choose the original product with safety certification when purchasing the charging head, so as not to reduce the battery life of the mobile phone too easily.
