1, the charger in the working process, the internal device will be stressed, slight vibration is inevitable, so it will emit a sizzling sound, which is a normal phenomenon; The use of unqualified chargers may also make Huawei mobile phones fast charging abnormal sound.
This situation is not normal, the general mobile power supply will not make a sound. The reasons for this situation may be: 1, there may be water vapor on the mobile power motherboard, resulting in a slight short-circuit sound on the motherboard. 2, the mobile power motherboard is issued in the process of boosting the voltageBut the sound is usually so small that it is almost inaudible.
According to your description, the wireless charger will have a slight sound when working in a quiet environment. This is the sound of the transformer working. It's a normal phenomenon.
The reasons for this situation are: the charger itself, electromagnetic interference, poor contact. The problem of the charger itself: some inferior chargers have not undergone strict quality testing, the internal circuit design is unreasonable, and it is easy to produce noise when working. If the parts inside the charger are damaged, such as inductors, capacitors, etc., it will also produce abnormal sound.
ChargerIn the working process, the internal device will have a force situation, slight vibration is inevitable, so it will emit sizzling sound, which is a normal phenomenon; The use of unqualified chargers may also make Huawei mobile phones fast charging abnormal sound.
When the mobile phone is being charged and turned on, the internal circuit of the machine and charger is working, and there will be a slight AC electric sound. If the sound is too loud, please take the purchase invoice, repair card, machine and charger to the service center, engineers check and handle.
Normal. Wireless charging is a wireless way to transfer power and the conventional power line to connect the mobile phone charging method is different, wireless charging only need to put the mobile phone on the charging board can be charged, this is a new type of charging method, through the principle of electromagnetic induction, the electromagnetic field energy into electricity, when working, the electromagnetic coil is under pressure, it will produce the corresponding vibration. And then make a sound, so wireless charging has a sound is normal.
When the mobile phone is being charged and turned on, the internal circuit of the machine and charger is working, and there will be a slight AC electric sound.If the sound is too loud, please take the purchase invoice, repair card, machine and charger to the service center, engineers check and handle.
During the working process of the charger, the internal components will be stressed, and slight vibration is inevitable, so it will emit a sizzling sound, which is a normal phenomenon; The use of unqualified chargers may also make Huawei mobile phones fast charging abnormal sound.
is related to current and voltage. The constant sizzling sound comes from the inductor coil inside the mobile power supply. When the mobile power supply is external, it is necessary to start the inverter circuit, and the inverter circuit should produce a certain frequency of alternating current when workingAlternating current belongs to the audio range and needs to be converted through an inductor coil. Under the action of a large current, the coil will vibrate and transmit the generated sound, so there is a small squeak.
Click [battery] in the phone Settings menu, click the option of [wireless charging Settings], turn on the switch on the right of [charging silent mode], the specific steps are as follows. Tool: iPhone1ios1 Local Settings Click BatteryClick [battery] in the phone Settings menu, as shown in the picture below. After clicking on wireless charging, click on the option of "wireless charging Settings", as shown in the picture below.
Mute mode is off. Open the "Settings" app, click "Sound and Touch", turn on the "silent mode" switch, the phone will not make a ding dong sound when charging. The charger is off. Buy a charger that can turn off the charging sound. After connecting the charger, press the "Mute" or "Silent" button on the charger to turn off the sound.
Operating mobile phone: IphoneXSMAX operating systemSystem: The steps to set the vibration of the iOS12 phone are as follows: Open the home screen of the phone, find and open the Settings screen. After entering the Settings screen, scroll down to find the sound and touch, and click to enter. After entering the sound and touch interface, you will see the detailed function setting interface for setting reminders.
This situation is not normal, the general mobile power supply will not make a sound. Expansion: The reasons for this situation may be: 1, mobile power motherboardThere may be moisture on it, resulting in a slight short-circuit of the motherboard. 2, the mobile power motherboard in the process of boosting the sound, but the sound is usually very small, almost inaudible.
Personal think and charging equipment is related, millet 80W wireless charging base built-in cooling fan, charging the default open speed wireless charging mode (feel the noise can be manually closed), we can hear the fan in the process of charging "buzz" sound, hand near the bottom of the wireless charging base, can also feel the cool wind blowing out of the fan. I hope I can help you.
Xiaomi wireless chargingIt mainly relies on the electromagnetic coil scheme for energy transmission, if there are too many obstacles between the coils, it will not only affect the charging power, but also lead to the aggravating of the heating problem, so it is also recommended that you take off the heavy mobile phone case when wireless charging, so that the mobile phone "naked" in the wireless charging seat is better Oh.
Click on the phone Settings page, select Sound and Vibration, then select Advanced Sound Settings, you will see the system Sound and vibration keys. After clicking, turn off the charging sound effect.
After insertion into the car, there will be a circle of white lights around. I used to drive 20 minutes,Basically, the power can be maintained well, and now the use of millet car charger effect is very good, can be filled with tens of percent of the electricity, the same as the original fast charge. Millet (MI) wireless car charger car wireless charger work is also very fine, the top is also equipped with a cooling fan, summer can automatically heat.
It is usually connected to the vehicle's power system through the vehicle's cigarette lighter socket or USB interface, and the car charger has portability and flexibility, and can charge the device during the drive or when parking, which is convenient for users to maintain sufficient power when using electronic devices in the car. Although now the car has developedMany of their own charging methods, such as their own charging bracket, as well as wireless charging stations, etc., but the car charger is still a necessary tool for many old drivers.
