If you are using a vivo mobile phone, it is recommended to use the original charger and data cable for charging; Restart the phone charging attempt; Take it to a service center for testing.

First look at the icon of the mobile phone showing the battery**, see if there is a small icon of charging lightning, if you don't change the cable, restart the phone, if it is still the same, it may be that the charging port is broken, take it for testing and repair.

There may be a problem with the charger or charging line, replace a charger, if the experiment is not good, it may be that the tail plug of the charging equipment itself needs to be replaced.

Try a different outlet. Or change to another charger to test. Eliminate these problems, it may be that there is a problem with the tail plug of the mobile phone or the motherboard battery charging module or the battery. Take the time to go to the after-sales maintenance station for testing and processing.

The plug doesn't work, Huawei's old C-port plug is easy to have this problem, use the original charging cable to see if it works, if it doesn't work, change the port.

Have you started charging, but it shows that the battery will run out? It could be because you didn't plug it in properly or there was a problem with your phone that didn't turn on

If you change the data cable, it is not the data cable problem that is basically blocked at the end plug, or the tail plug is broken.

Restart the phone once and try to charge it again, it should be that the phone system detects that the charging status is wrong, and the charging of the smartphone is controlled by the software.

That means it is not charging, it may be that the charging cable is broken or there is something wrong with the phone.

Check that the charger and plug are in good contact and then shut down to try after restarting!

It may be that the charger is in poor contact, just wipe it with an eraser.

You unplug the power supply and plug it back in, the contact is not good.

Check the charger, cable, and phone battery all over again.

Probably not so fast.

If there is a problem with the battery level display, I will directly shut down and restart.

It is caused by an error in the battery setting, and the solution is as follows:

If the phone no longer shows charging when charging, it means that there is a problem with the part of the phone that shows charging, but it can actually be used when it is charged.

Generally, it is a display problem, or it is a problem with the hardware of a mobile phone to detect the battery.

、About the aboveWhen the phone is charging, it doesn't show charging, but it has actually been charged, what's going on? To solve this problem, first check whether the original charger is normal.

Check whether there is any poor contact inside the original charging data cable.

Check the charging cable plugwithMobile phone charging tail plug, look at the inside between the two, whether there is poor contact, etc.

Check if the battery inside your phone is normal.

Plug and unplug repeatedly. In this case, most of them are due to poor contact with the charging port of the mobile phone.

Does that have to change the charging port?

Yes. But it can be charged, why does it show up when you restart?

Shut down and restart, which is equivalent to data refresh, and the general power indicator will return to normal.

But only for a short period of time.

It is caused by an error in the battery setting, and the solution is as follows:

If the phone is not plugged into the charger and the charging is displayed, you can use the following methods to troubleshoot:

1. Restart the phone or plug the data cable again to see if there is any improvement.

2. It is recommended to change to the desktop theme that comes with the mobile phone, some third-party theme design defects, and the charging icon is always displayed.

3. Please confirm whether you are using a non-standard charger and data cable, as the use of non-standard chargers and data cables may not be compatible with the mobile phone, resulting in an abnormal display of the charging icon.

4. Please confirm whether there is any dirt and blockage in the charging port of the mobile phone, and it is recommended to use a dry soft brush to clean it and try it.

Principle: The working process of the battery to receive electrical energy from the external circuit and convert it into the chemical energy of the battery. After the energy of the battery is consumed by discharge, it can be restored by charging and can be re-discharged, constituting a charge-discharge cycle.

Generally, it is charged with DC current (also with asymmetric AC current or pulse current). In different cases, different charging methods are used, such as constant current charging, constant voltage charging, floating charging, trickle charging, emergency charging or a combination of these methods.

According to the formula of the electric voltage, current and time, in the case of a fixed electric amount, the charging time can only be shortened by increasing the voltage or increasing the current.

High-voltage charging: high-voltage and low-current mode, increasing voltage, requires multiple step-down circuits to be designed in the charging circuit. When charging, the charger will heat up, and the phone will also heat up, and the safety of the battery will be affected.

Low-voltage charging: low-voltage high-current mode, increasing current, introducing MCU monolithic microcomputers in both charger circuits and battery circuits to replace step-down circuits. Under the premise of low voltage and high current, the output of the current with segmented cross-flow is realized through the open voltage loop.

VOOC flash charging uses the solution of low voltage and high current to ensure safety and solve the problem of mobile phone charging and heating. <>
