Some Samsung mobile phones support wireless charging function, which requires a separate charging kitWireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone.
Many people worry about the harm of electronic devices to the human body, but in fact, this is not need to worry, the closed magnetic field is very safe, will not interfere with the mobile phone signal, and low temperature fast charge function, charging will not heat. Of course, the most important thing is the charging effect, wireless charging although relatively slow, but the effect is still very stable.
Long-term use of radio charging will not affect the phone. Wireless charging is characterized by the absence of the limitation of the charging line, which is affected by the nickel-metal hydride batteryWith memory, the best way to use is to reach the best state of the battery after charging. The wireless charging method does not have the bondage of the line, and takes it with each charge, reducing the complexity of plugging and unplugging the data cable.
Wireless charging technology is implemented using the principle of electromagnetic induction, although it will also produce radiation, but it will not cause harm to the human body. Qi standard Qi is the current more authoritative standard, with Qi logo wireless charger, most mobile phones can be universal, without considering the brand of the mobile phone.
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.
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; Use notQualified chargers may also make Huawei mobile phones fast charging abnormal sound.
Mobile phones do not support wireless charging, Huawei car wireless charger only supports mobile phones that meet the qi wireless charging standard. The charging distance is too far, and the wireless charging distance is generally less than 5mm. Chargers are not compatible with mobile phones, and some in-car wireless chargers only support certain brands or models of mobile phones.
Check whether the phone is overheating, it is recommended to charge in a good heat dissipation environment. Check whether the wireless charger indicator light is on normally, and check whether the connection between the charging base, data cable, charger and power supply is in poor contact.The purchased wireless charging base is a third party, please go to the purchase website to check whether the base is QI certified (official website query or whether there is QI Logo). If the base you buy does not have Qi certification, it will lead to the problem of being unable to charge the phone, it is recommended that you use the one plus base.
2, wireless charging speed comparable to the wired flagship mobile phone recommended one plus 10Pro in charging, this phone is equipped with 80W wired fast charge and 50W wireless fast charge, in wired mode can do 32 minutes of rapid blood return, wireless mode about 47 minutes full charge, and the gap is not compared with wiredIt's huge. Fast charging, long battery life, from then on out to say goodbye to electricity anxiety.
3, as a wireless charging base, magnetic wireless charging not only provides efficient heat dissipation, but also realizes multi-scenario applications. Whether it is gaming, live streaming or daily use, it can easily cope with the double improvement of performance and convenience. Of course, despite the slightly larger size, this is an acceptable minor drawback for those users who are looking for performance and convenience.
4, using the original wireless charging base, measured 5 minutes can be charged from 1% to 10%, 10 minutes can be charged to 19%, 30 minutes can beCharge to 47%, full charge takes about 80 minutes, slightly slower than wired. However, its wireless charging dock also requires an additional purchase.
5, Oneplus 8 series new products will bring wireless charging and improved vibration experience, one plus technology CEO Liu Zuohu revealed on Weibo that the Oneplus 8 series new products will join the highly anticipated wireless charging function, the design goal is to make the wireless charging experience comparable to wired charging, ensuring that users find the ideal balance between convenience and performance.
6, Note: If this function is opened for a long time without its wireless noise reasons His device charging will automatically turn off; This function cannot be enabled when the battery life of the phone is less than or equal to 15%.
1, the lithium battery of the charging treasure is the same as the mobile phone, most of them are 7V, such a voltage is unable to charge the mobile phone, so the charging treasure will boost to about 5V, this process needs to boost the voltage coil, you hear the sizzling sound is issued by it, the better charging treasure may sound relatively small. The inductance on the mainboard of the charging bank generates high-frequency electricityMri, it doesn't matter.
2, the circuit is designed with a switching power supply, in which the switching transformer will make a squeaking noise, which is the sound of the magnetic core is not tight and the oscillation frequency is higher. It's a transformer. They all make sounds just big and small. The squeak emitted by the high-frequency transformer is not loud and has no effect on the circuit and can be ignored.
3, millet 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 millet after-salesConsult and check.
4. For charger compatibility, the Xiaomi 30W vertical wireless charger and 20W version provide flexibility when used alone. For example, the 80W Sail wireless charger requires 20V PPS/MiPPS protocol to activate the fast charge above 30W, while the Xiaomi 50W vertical charger Pro requires a specific charger above 67W to achieve its full potential. Redmi 30W wireless charger has higher requirements, and specific activation conditions may vary.
The reasons are as follows: There may be water vapor on the main board of the mobile power supply, resulting in the sound of a slight short circuit on the main board. Mobile power motherboard in the process of boosting the sound, but this sound is usually very small, almost inaudible. If it is a slight noise, it may be the sound emitted during the current transmission process, which is a normal phenomenon, and the user does not need to take care of it.
Personal think and charging equipment is related, millet 80W wireless charging base built-in cooling fan, charging default open speed wireless charging mode (feel loud can be manually closed), we are chargingDuring the process, you can hear the "buzz" sound of the fan, and when your hand is near the bottom of the wireless charging seat, you can also feel the cool wind from the fan. I hope I can help you.
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.
Millet 100W wireless charger appearance packaging box is still black color, the middle of the front is a golden edge pattern, and the wireless charging shape is contrasted, the words above and below 100W indicate that the wireless charging power of this product is a higher level, the upper right corner of the millet logoAlso used the latest version. The back is affixed with a 100W wireless charging base package information sticker, and printed with wireless charging, data cable and charger schematic.
is related to current and voltage. The constant sizzling sound comes from the inductor coil inside the mobile power supply. The mobile power supply needs to start the inverter circuit when the inverter circuit works to produce a certain frequency of alternating current, which belongs to the audio range, and needs to be converted by the inductor coil, under the action of the larger current, the coil will vibrate, and the generated sound will be transmitted, so there is a small squeak.
Set in the circuitThere is a switching power supply, in which the switching transformer will emit a squeaking noise, which is a sound with a higher oscillation frequency because the magnetic core is not tight. It's a transformer. They all make sounds just big and small. The squeak emitted by the high-frequency transformer is not loud and has no effect on the circuit and can be ignored.
1, under the standby desktop - Click Application - Settings - More network - Mobile network - Network operator - Search network- Choose the network operator supported by the SIM card to replace a SIM card and try to check whether the phone is installed Wireless charging noise reason Software such as Security Guard or Caller ID Wireless charging noise reason , uninstall and try.
