When the phone is charging, it will be high and low, what s the matter?

In the case of charging high for a while and low for a while, it is recommended that you try the following:

1.Shutdown charging test.

2.Replace the charging position to rule out intermittent contact caused by poor contact with the socket.

3.If conditions permit, replace the spare charger for testing. Or send it for repair and testing.

4.When the phone is turned on and charged, if the mobile phone is equipped with a third-party plug-in such as a charging doctor, it is recommended to test it after uninstalling it.

5.Check whether there are foreign objects in the charging interface of the mobile phone, such as liquid ingress and debris that cause poor contact between the charging interface of the mobile phone and the charger, if this situation is recommended to be repaired as soon as possible.

6.Back up your phone data (**book, text messages, **, etc.), factory reset your phone.

Go to Phone Settings - Reset - Factory Reset).

If the above methods cannot solve the problem, you need to send it to a professional for repair.

You should have a problem with the protection chip inside the battery, and the detection data reflected by the protection chip to the system is wrong, this phenomenon may be that your battery has been used for a long time, the life is up, or this phenomenon will appear on the non-original electric board, go buy a new battery and try it.

I've also encountered this, and the phone is still hot, so I changed to a new phone.

Maybe there's something wrong with the board.

Hello, generally this situation is that there is a problem with the battery, and there are some problems with the phone's battery display, you can restart it to try.

It's a charging problem.

The reasons why the mobile phone is charging and playing with less and less power are as follows:1The mobile phone is aging, so the power tolerance is low.

2.There is too much software running in the background, which causes the power to be charged at a speed that cannot be used. 3.

The games played occupy too much CPU and the running demand is large, which will also lead to less and less power while charging and playingExpand the data:1When using mobile phones, you should pay more attention to cleaning up garbage, and clean and disinfect regularly.

2.If you don't use it, you should disable it from starting automatically, running it in the background, or uninstall it directly. 3.

When charging and playing with your phone, you should turn off all the unnecessary running software, and it is best to run only one software. 4.When charging, pay attention to heat dissipation, hold both sides of the phone with both hands, and do not hold the phone in a large area, which will affect the heat dissipation.

Questions. Is there any way to speed up the charging?

You can buy a fast-flushing charging head.

If you are using a vivo mobile phone, if the mobile phone is in the working state with the screen on, the mobile phone itself generates a certain amount of heat, and in order to ensure the user experience, the charging power will be intelligently adjusted to reduce heating.

The charging time will increase to a certain extent.

To increase the charging speed, it is recommended that you use the following methods:

1. The mobile phone should be at a low initial charging temperature as much as possible, for example, the mobile phone is in working state before charging, you can turn off the screen and wait for the mobile phone to cool down before starting charging;

2. Try to exit the background app while charging, and turn off the screen;

4. When charging, place the mobile phone on an object with good heat dissipation (such as a desktop) or a well-ventilated place (such as a place where a fan or air conditioner can blow it), and avoid placing it on objects that are not easy to dissipate heat (such as sofas, quilts, blankets).

If your phone is also charging slowly when it is in standby, it is recommended:

1.Use the original charger to turn off the charging and check whether the phone is slow to charge when it is turned off.

2.If your phone is only charging slowly when it is turned on, please do you:

1) End the end-run program (Recent Applications button in the bottom left corner - End) 2) Uninstall the third-party battery management software from your phone.

1) Check if there is a version update on your phone and upgrade to the latest version.

2) Please back up the data in your phone and restore your phone to factory settings.

3) If the above methods are invalid, please bring the purchase invoice, warranty card and machine to the Samsung service center, and a professional after-sales engineer will help you deal with it.

Here's why:1Using a mobile phone while charging will make the current density of the circuit through the lithium battery much higher than that of the mobile phone battery used in the non-charging state.

2.The increase of circuit density will lead to the increase of the internal voltage drop of the lithium battery, and the electrochemical energy will be converted into more coulombic heat, and the generation of heat energy will further increase the internal resistance of the lithium battery, and then continue to increase the internal resistance of the lithium battery and the coulombic heat generated, forming a vicious circle.

3.Eventually, the overvoltage increases, and the charging and discharging voltage of the lithium battery detected by the safety voltage sensor set on the back of the mobile phone is not the real charging and discharging voltage, and the real voltage will exceed the specified safety voltage potential window or cut-off voltage (cut-off), resulting in the destruction of the chemical structure and composition of the lithium battery electrode material, and the collapse of the material structure, resulting in a rapid decline in battery performance, and the power will be less and less. Or the battery bulge or even**.

Summary. The reasons for the unstable charging of mobile phones are as follows: 1. The problem of tail plugging of mobile phones.

Check whether the tail plug of the mobile phone is loose and whether it is connected when the charging cable is inserted. 2. Data cable problems. Check whether the data cable is broken, and when the charging is unstable, you can shake the data cable slightly to check whether it is falsely connected.

3. The problem of the charger's big head. Check if the plug is broken, you can try to change the plug of another mobile phone.

The charging current of the mobile phone fluctuates up and down.

The reasons for the unstable charging of mobile phones are as follows: 1. The problem of tail plugging of mobile phones. Check whether the tail plug of the mobile phone is loose and whether it is connected when the charging cable is inserted.

2. Data cable problems. Check whether the data cable is broken, and when the charging is unstable, you can shake the data cable slightly to check whether it is falsely connected. 3. The problem of the charger's big head.

Check if the plug is broken, you can try to change the plug of another mobile phone.

The details are as follows: 1. Whether the mobile phone charger charging cable supports fast charging. The current supported by different charging cables is also different, you can try other people's data cables, and the charging speed is normal after changing the cable, which means that it is time to change the data cable.

It is best to use the original charging cable. In order to prevent the socket from being damaged and causing misjudgment, you can also try to change the power socket. 2. Check whether it has entered the fast charge.

If the phone supports fast charging, but the charging speed is still slow, you can check whether it is caused by the phone not entering the fast charging. You can use the phone charging icon to determine whether the phone has entered the fast charging mode. A single lightning bolt represents ordinary charging, a large and a small double lightning represents fast charging, and 3. The influence of charging temperature.

Due to the characteristics of lithium batteries themselves, they are more sensitive to temperature, so when charging, the temperature is too high or too low, which will damage the service life of the battery.

The temperature of the absolute waiting when charging quietly trembles.

In a low temperature environment, the charging speed will be much slower than usual, and if the temperature is high, the charging speed will be faster than usual. In the winter, the charging speed is significantly slower.
