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.
Normal. Wireless charging is through the wireless way to transmit power and the conventional power cord connection 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, is through electromagnetic inductionThe principle of the electromagnetic field energy into electricity, at work, the electromagnetic coil is under pressure, it will produce the corresponding vibration, and then emit sound, so wireless charging sound is normal.
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.
. If it is slightNoise may be the sound emitted during the current transmission process, which is a normal phenomenon, and the user does not need to pay attention to it. If the noise is large, it may be the charger problem, you can change the charger to try charging. If the noise comes from the mobile phone, it may be a short circuit or leakage of the internal circuit of the mobile phone, or it may be a fault of the tail plug, and it needs to contact Xiaomi's after-sales service to repair the mobile phone to solve it.
The reasons are as follows: The mobile phone charger is currently working in an overload state, that is, the maximum power supply current provided by the mobile phone charger is less than the normal charging current of the load. Solution: Change the power of the higher charger to negativeLoad charge. The magnetic core of the high-frequency transformer inside the mobile phone charger is loose, resulting in a buzzing sound when the transformer is working.
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 battery Click [battery] in the phone Settings menu, as shown below. After clicking on wireless charging, click on the option of "wireless charging Settings", as shown in the picture below.
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. Further developmentSound, so wireless charging has sound is normal.
Mi charger. If it is wireless charging, sometimes he has some sound is very normal, so do not worry about this is also a normal phenomenon when he charges, if the sound is larger, you can go to the millet after-sales consultation to check.
mate50pro with wireless charging with current sound is a high-frequency transformer inside the charger. During the working process of the charger, the internal devices will be stressed, and slight vibration is inevitable, so it will emit a sizzling sound, which is a normal phenomenon. When not charging, it is necessary to pull out and charge in timeLine charge Wobble '> Why my Apple Magnetic Wireless Charge Wobble
Insufficient magnetism, the charger is broken. Lack of magnetism. The magnetism of iwatch3 is insufficient, and the magnetism is not enough to support the magnetism used when iwatch3 is charged, so the magnetic absorption will run off when iwatch3 is charged. The charger is broken. The charger of the iwatch3 is broken, so the magnetic magnet will run off when the iwatch3 is charging. Magnetic charging cable refers to the charging cable through the magnet male and female suction mode to achieve the charging effect.
You mean you can feel a slight vibration, that's a leakElectricity, or the human body is more sensitive, I can also touch it, my macbook and ipad can touch it, but it is blocked by the electrical meninges. Before my husband fishing under the high-voltage line, I touch his ears feel buzzing, crisp, he can not feel, I am more sensitive.
The main reasons for the mobile phone charging interface loosening: the charging port is dusty, resulting in the charging cable socket is not in place; Use a fine toothpick to gently pick in the tail insert, confirm whether there is dust, pick out dust, wipe with alcohol cotton; First find the card needle or sewing needle that comes with the phone, and then gently swipe the card against the quasi-interface hole untilClean the dust out of it.
The reasons for this situation are as follows: First, the magnetic phone case will interfere with the wireless charging coil of the phone, affecting the charging effect. The wireless charging coil of the mobile phone needs to be accurately aligned with the coil of the charger to achieve charging, and the magnetic phone case will change the shape and weight of the mobile phone, making the wireless charging coil and the coil of the charger cannot be accurately aligned, resulting in poor charging effect.
