The voice sent by the mobile phone WeChat is noisy, and I can't hear it clearly, but the call is normal. What happened?

Mobile phones are in every aspect of daily life, so it is very common that mobile phones have no electricity. What should I do if I find that my mobile phone cannot be charged when charging?

First, the long-term use of mobile phones leads to battery damage. The solution is to replace the battery. It is recommended not to replace it yourself, but to replace it after sale.

Second, the charger is damaged. Replacing the charger can solve this problem.

Third, it may be that the charging cable is in poor contact with the mobile phone. Connect the charging cable and the mobile phone repeatedly to see if this problem can be solved. If it can't be solved, you can wipe the port of the mobile phone charger with a cotton swab. Sometimes there is something wrong with the touch screen of the mobile phone. There may be sweat or oil on your hands, which leads to stains on the screen. Just wipe the screen of the mobile phone clean.

There are usually three situations: the phone is dead, the phone is over-brushed or the battery is damaged. If the phone can't be turned on because of low battery, charge it. If it can't be turned on because of excessive brushing, download a matching ROM package. If the battery is damaged and the phone cannot be turned on, just replace the battery. What if the mobile phone is broken?

The battery is too low to start.

1, the battery of the mobile phone is seriously under-used, which leads to the automatic shutdown of the mobile phone, and it still cannot be started normally after just plugging in the charger. The reason is that the smart phone can only be turned on when the power is greater than, for example, 5%. When the power is too low, it naturally cannot be turned on.

All we can do is wait for the phone to charge for 5 minutes, and then try again.

Excessive brushing caused the machine to fail to start.

1, swiping the mobile phone is equivalent to changing the system of the mobile phone. By brushing some new systems, the user experience of mobile phones can be improved. But sometimes, because some mismatched ROM packages are brushed, the mobile phone is likely to be unable to boot and stay in the boot interface.

2. In view of this situation, we can only download a matching mobile phone ROM package and put it in the SD card of the mobile phone, then enter the recovery mode of the mobile phone and brush the mobile phone again to solve it.

The battery is damaged and cannot be turned on.

1, mobile phone batteries are consumables. If the mobile phone is used for a long time, it will be damaged or malfunction prematurely.

2, you can connect the phone to the charger, see if the phone will show that it is charging, and see if the percentage of electricity will increase, so as to simply judge how the battery is. If the battery is damaged, it is recommended to replace it with a new one.

Generally speaking, mobile phones can't be turned on because of low battery, just need to be recharged. Unable to boot because of excessive brushing. Just download a matching ROM package. If the battery is damaged and the phone cannot be turned on, replace the battery.
