When charging, the breathing light is set and does not light up, how to solve it

How to set the app message breathing light prompt: Go to the phone's settings - Notifications and status bar (open on this interface: the breathing light flashes when you receive the notification) - notification management - select the app that needs to turn on the prompt and click to enter - turn on the breathing light flashing.

That is, if it is broken, it can't be used, so buy a new one.

The reason why the indicator light does not light up is that the option of turning off the phone charging indicator light is turned off, and the method of turning it on is as follows:

Open the app in standby and tap Settings to open it.

Click the phone display to turn on, then turn on the LED light function, and check the option prompted by the charging option to select.

There will be an indicator light to remind you when charging.

1. When the notification switch is turned on and the screen goes off, the breathing light will turn on when you have missed calls, unread text messages or notifications; The switch is turned off, and the breathing light does not respond;

2. The low power switch is turned on, and the breathing light will light up when the battery power is lower than 10%; The switch is turned off, and the breathing light does not respond;

3. The charging switch is turned on, and the breathing light lights up when the phone is connected to the charger; The switch is turned off, and the breathing light does not respond;

The data light doesn't turn on when charging, it may be broken, you check it again and try it to see what the situation is.

Summary. Workaround:

What should I do if my Huawei phone can't turn on with a red light? Under normal circumstances, the mobile phone turns off with a red light because the battery is exhausted, under normal circumstances, the mobile phone will flash a green breathing light when we are charging, if the power is lacking, it will display yellow, and if it is red, in most cases, it will be automatically turned off because the mobile phone is out of power.

At this time, charging, a red light will flash in a short period of time, and it will not be able to turn on, which is a normal phenomenon, at this time, you need to continue to wait for charging for more than ten minutes, and you will see that there is a display of charging on the screen, under normal circumstances, it is more difficult to turn on the power below 5%, as long as you rush to the power that can be turned on, the mobile phone will automatically turn on.

Rest assured, most of this situation is not the phone is broken, if you wait for more than half an hour and can not turn on normally, you need to check whether it is charged, if it cannot be charged normally, you can gradually check: whether there is electricity at home, whether the plug-in board is open, whether the mobile phone charging cable is plugged in, whether the charger is broken.

If the device still can't be turned on after the check, you can bring the proof of purchase (if it is under warranty) to Huawei after-sales service for testing.

The fault that the electric vehicle charging indicator does not light up is divided into two types: the charging system can be charged and the charging system cannot be charged.

Method 1: The charging indicator does not light up when the ignition switch is turned on, and the generator can generate electricity after starting the engine, indicating that the generator charging system is normal. You can check whether the charging indicator on the instrument panel is working properly, and if the filament is broken, it needs to be replaced.

Method 2: When the ignition switch charging indicator is not lit, and the generator cannot generate electricity after starting the engine, the troubleshooting method is as follows: Turn off the ignition switch and check the instrument fuse.

If the fuse is broken, replace the fuse with the same specification; If the fuse is good, continue to check.

Turn on the ignition switch and use a multimeter.

Detect the voltage value on the fuse, if the voltage is zero, it means that the ignition switch and the circuit between the ignition switch and the fuse are faulty, and should be overhauled or replaced. If the voltage on the fuse is normal, check the generator brushes.

Poor contact with the collector ring or faulty internal circuit of the regulator.

The reasons for the failure of the car charging indicator are as follows:1. The charging indicator circuit is open or in poor contact.

2.The charging relay is faulty. 3.

The AC motor and regulator are faulty. (1) The charging indicator circuit is open or in poor contact. For example, the power cord of the charging indicator is broken, the bulb is burned, the fuse is blown out, or the plug is loose.

2) The charging relay is faulty. For example, the closing voltage of the relay contact of the charging indicator is excessively adjusted, and the electromagnetic attraction generated by the coil is difficult to attract the contact; It means that the charging relay coil or neutral wire is open, so that there is no voltage at both ends of the relay coil, and the contacts cannot be attracted; It means that the contact of the charging relay is ablated and oxidized, and the contact is poor after being dirty. At this time, the alternator can still generate electricity when operating at a certain speed, but due to the low excitation current, the generator output current is insufficient.

3) The AC motor and voltage regulator are faulty. Such as pressure regulator contact ablation, oxidation or poor contact; Alternator diode breakdown or failure (it should be noted that if this is the reason, it must be eliminated as soon as possible, and the generator is not allowed to run for a long time so as not to burn out the other diodes and stator windings of the alternator), etc. In the diagnosis, the method of checking the power generation of the alternator can be used, and the commonly used methods are the lamp inspection method, the multimeter method and the DC voltmeter method to diagnose whether the alternator generates electricity.

If the alternator generates electricity, it means that the fault is caused by the charging indicator relay, otherwise the alternator itself has a troubled obstruction.

The breathing light on your phone will light up during text messages, missed calls** and charging. In general, if the breathing light does not light up when the phone is charging, the possible reasons are:

The phone is damaged and other external factors cause it to not light up. It is not excluded that some mobile phones will be set to display the function of breathing light, and the reason why it does not light up may be that it is not set to display breathing light. If the first reason is the case, there are several cases:

The electrode contacts of the battery are dirty, the contact resistance is too large, and the voltage drop is too large, and the host thinks it is full and stops charging when charging; The internal charging circuit of the mobile phone is faulty and cannot be charged normally; There is a malfunction inside the battery. There is a malfunction in the charging equipment, such as an abnormal data cable or charging head. Mobile phone software failures can be solved by flashing the phone.

Hardware failure of the phone. For example, the charging interface is not in good contact, etc. Other.

If too much software runs in the background, the input is less than the output, causing the phenomenon of not charging. Judgment method:

Problem 1: You can wipe the contacts clean with a clean eraser, which can generally solve 80% of the problem.

Question 2: You can find a universal charger to try whether it can be used normally, if it can be used normally, you can judge that it is a problem with the mobile phone, and then you can always use the universal charger to solve this problem.

Problem 3: The battery can be replaced, observe whether it can be used normally after replacing the battery.

Question 4: Replaceable charging equipment reputation, observe whether it can be used normally after replacement.

Question 5: Flash the machine to see if it returns to normal.

Question 6: Replace the hardware of the phone and observe whether it returns to normal.

Problem 7: Reducing the amount of software running in the background.
