This article gives you a talk about wireless charging rattle, and wireless charging ring non-stop corresponding knowledge points, I hope to help you, don't forget to collect this site. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Wireless charge always ring when charging isWhat problem
If the phone has abnormal ringing during fast charging, it is recommended that you: disconnect the machine from the charger and reconnect it. Use the original charger to charge your phone/tablet. If conditions permit, replace other available chargers for charging. If the problem still exists, it is recommended that you take the purchase invoice, repair card and machine to the local Samsung after-sales service center, by a professional engineer to help you detect.
Well, you add a Schottky high frequency diode in series to a 10 ~ 16v capacitor, and then add a 10 ~ 19 resistor in parallel to the capacitor, you should first put the receiving end when you tryThe mobile phone can be charged on the charging board, which is a new type of charging method, through the principle of electromagnetic induction, the energy of the electromagnetic field into electricity, at work, the electromagnetic coil is under pressure, it will produce the corresponding vibration, and then emit sound, so wireless charging has a sound is normal.
Due to the limitations of the network platform, it is not possible to check the specific situation of the mobile phone, it is recommended that you bring the purchase invoice and three package voucher to your nearest after-sales service center, and let the engineer help you test it. Samsung Service center address information/customer service phone number, can be queried by the following methods: Please login threeStar official website service center page Select the product you want to query and the province where the city to search.
Of course, it does not rule out that your charging strip is in poor contact, and this time it is necessary to check your circuit.
If your Samsung S9 beeps while charging and cannot be charged, the following conditions may exist: Charging cable or charger failure: The charging cable or charger may be faulty or damaged, causing it to fail to charge properly. You can try to replace the charging cable or charger, or use another brand of charger for charging. Charging port failure: The charging port may be faulty or damaged, resulting in normal contact with the charger.
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 in the process of boosting the sound, but the sound is usually very small, almost inaudible.
indicates that the mobile phone charger is not well connected, you will re-check the charging head and data cable, and then connect it well for charging, if it can not be charged, it means that the data cable or power plug is broken, replace it with a new oneTo charge up.
This is often caused by poor data line contact, replacing a good data line can solve the problem, after the replacement or can not be used is the mobile phone problem, need to be repaired. When charging, ding-dong ding-dong is the phone switches between charging and disconnecting two states.
Plug in the charger for charging, there is a buzzing sound, which should be cold in winter weather, not the best temperature range for normal use of the charger, so at first the fan rotates slowly, there is current sound. It may also be the weather, the sound of the ballast circuit, after a period of time the circuit heats up, and the temperature reaches the chargeThe device uses a normal temperature range, then it can be used normally, so the buzzing sound will disappear.
Poor contact between the charger and the power socket: The charger is in poor contact with the power socket, and the current transmission will be unstable, resulting in the phone constantly switching the charging state and making a sound. Try re-inserting and unplugging the charger, making sure the plug is tightly connected to the socket. Poor contact between the data cable and the mobile phone charging interface: poor contact between the data cable and the mobile phone charging interface will also lead to unstable current transmission, and the mobile phone will continue to emit a charging prompt tone.
1. If you use a Huawei mobile phone or tablet, there will be a prompt tone when the Huawei mobile phone/tablet is inserted into the charger by default. You can drop down to enter the status bar or control center, and set the mute or vibration mode in the shortcut switch panel to eliminate the prompt tone.
2, Apple charging old ring is a lot of Apple mobile phone users will encounter the problem, then what is the reason for this problem? The charging interface located at the bottom of the phone is easy to enter the ash, which causes poor contact between the interface and the power cord plug. Solution: CheckCheck the port on the bottom of the phone for any blocked objects. The charging cable and power cable are damaged. Solution: Replace the phone's charging cable and power cord.
3, the reasons are as follows: Charger failure: If the charger is faulty, such as a short circuit or unstable power output, it may cause the phone to make a sound when charging. Charging port dirty: If there is dust or dirt on the charging port, it may lead to unstable charging, which makes the phone sound when charging. Aging battery: If the phone's battery is aging, it may lead to unstable charging, which makes the phone ring when charging.
4, if you need to turn off the prompt tone connected to the power supply, you can turn the phone to silent or vibration mode; If you need to turn off the prompt sound emitted by Full charge, you can go to Settings -- Applications and permissions -- Application management -- click the dot in the upper right corner -- Display system program -- system interface -- Notification -- Charging complete /Full Battery-- Sound -- select mute, if you do not have this option, you need to mute to turn off.
5, the data generated by the running program leads to system disorder: in this case, the phone charging will not damage the screen, you can use the original charger, data cableTry it, you can also change other chargers, try the data cable, you can also change a new battery.
Poor contact: The plug of the charging bank is not strictly in contact with the power socket, causing the virtual connection to squeak. Poor inductance quality: the changing current flowing through the inductance coil will have the effect of electromagnetic force, and if the inductance quality is poor, it will emit an obvious high-frequency sound, which does not affect the use of the sound.
The plug of the charging bank is not strictly in contact with the power socket, causing the virtual connection to squeak. It's chargingThe tiny electric sound made by a treasure charger. mobile power pack, English mobile power pack (MPP), also known as power bank, travel charger, etc., is a portable charger that integrates power supply and charging functions, and can charge mobile phones and other digital devices anytime and anywhere or standby power supply.
There is a DC-DC conversion circuit in the charging treasure, which is working in the oscillation state, if the inductor's magnetic core is loose, it may be able to hear a weak sizzling sound in a very quiet environment, just like an electric mosquito clap can also be heard, this is not a fault, you can rest assured.
There is a tiny sizzling sound when the charging treasure is charging, which is related to the current and voltage. The constant sizzling sound comes from the inductor coil inside the mobile power supply.
Generally speaking, a normal charging bank should not have any sound during the charging process. If you hear a sizzling sound, it may be due to the failure or abnormal working of the electronic components inside the charging bank. It is recommended to stop using the power bank immediately, and contact after-sales service or professional maintenance personnel as soon as possible for inspection and repair, if continued use may lead to more serious damage.
Cause: There is a DC in the power bankThe DC conversion circuit, which is working in the oscillation state, the inductor's magnetic core is loose, and a weak sizzling sound can be heard in a very quiet environment, which is not a fault and can be used with confidence. Note: Do not adjust the output voltage higher than the device voltage; otherwise, the device may be damaged. Use the specified charger. Stop short-circuiting, differentiation and throwing into the fire.
