1, the disadvantage is low efficiency and can only provide electricity. The body's response to electric fields is strong, but the body's response to magnetic fields is almost non-so this system does not affect human health. As an electronic charging product, the charger itself can not avoid radiation, so it is inevitable that the wireless charger has radiation. However, the current power of the wireless charger is very small, the charging time is longer, the radiation generated is also small, and it should not cause great harm to people.
2, some Samsung mobile phones support wireless charging function, to achieve the function requires a separate charging kit, wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone.
3, Samsung's technology is not mature, can not do wireless charging. So there are two contacts left in the rear cover of the Samsung I9300. Let's get everyone wireless charging. It failed. The Nokia 920 also seems to have launched a wireless charging jacket, but it's still not practical. Cortec recently introduced a wireless rechargeable battery. Wireless charging can be achieved without changing the appearance of the phone. You can find it on Taobao. There should still be great potential for development.
4, for the human body: wireless charging technology is safe and harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is common only at the same frequencyIt is related to the charging device, Xiaomi's 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 "buzz" sound of the fan in the process of charging, hand near the bottom of the wireless charging base, can also feel the cool wind blown by the fan. I hope I can help you.
4. If it is a slight noise, it may be the sound emitted during current transmission, 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 noiseFrom the mobile phone, it may be the internal circuit of the mobile phone short circuit or leakage, it may also be the tail plug fault, need to contact millet after-sales service to repair the mobile phone to solve.
5, some Samsung mobile phones support wireless charging function, to achieve the function requires a separate charging kit, wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone.
1, This situation is not normal, oneThe mobile power supply will not make a noise. 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.
2, personal think and charging equipment, millet 80W wireless charging seat 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 close to wireless chargingAt the bottom of the electric base, you can also feel the cool wind from the fan. I hope I can help you.
3, Mi wireless charging mainly relies on the electromagnetic coil scheme for energy transfer, 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. Let the phone "naked" lying on the wireless charging seat is better.
4, click the phone Settings page, select sound and vibration, and then select advanced sound Settings, you will see the system sound and vibration keys. pointAfter clicking, turn off the charging sound effect.
It is normal for the small fan inside the Huawei wireless charger to keep turning once it is plugged in, because the small fan is used for the power supply of the charger and the chip inside to dissipate heat, so it is normal for it to keep turning.
Hello, please charge the phone with the screen facing up in the center position of the charger or the position suggested by the charger manufacturer.
If you are conducting wireless charging, because there will be energy loss in the wireless transmission process, and then generate a certain amount of heat, there will be a phenomenon of heat when wireless charging, this is normal.
When the wireless charger is powered, directly place the phone screen facing up in the center position of the charger or the position suggested by the manufacturer to charge.
1, the charger in the working process, the internal device will be stressed, slight vibration is inevitable,So it will make a sizzling sound, which is a normal phenomenon; The use of unqualified chargers may also make Huawei mobile phones fast charging abnormal sound.
2, it is recommended that you use the standard charger to charge the use of other third-party chargers, although you can also charge the phone, but due to differences in charging specifications or charging protocols, it may cause problems such as heating.
3, in order to ensure that your sleep environment is quiet, it will automatically enter the silent charging state, and the fan speed will be reduced. During this time, the phone/charging pad intelligently adjusts the wireless charging power, and the charging speed is slower than the rest of the day. Huawei50w fast charge after 9 o 'clock automatic slow down silent charging, after 7 o 'clock in the morning the speed is normal, before I thought it was bad, who knows there are such rules, mainly can not close this limitation is the most uncomfortable.
How to turn off the wireless charger fan? The first thing I want to do is to unplug the fan, but the charging function cannot work properly after the actual unplug.
Personally believe that it is related to charging equipment, Xiaomi's 80W wireless charging seat has built-in cooling airFan, the default charging speed wireless charging mode is opened (feel the noise can be manually closed), we can hear the "buzz" sound of the fan in the process of charging, and when the hand is near the bottom of the wireless charging seat, we can also feel the cool wind blown by the fan. I hope I can help you.
Connect the standard charger and data cable of the mobile phone to the wireless charger, and then put the mobile phone in the center position of the left and right of the wireless charger base, you can realize wireless charging, the indicator light will have a breathing effect, 5 seconds later, plug and play, convenient and quick.
Huawei wireless charger once plugged in the power inside the small fanIt is normal to turn all the time, because the small fan is used to heat the power supply of the charger and the chip inside, so it is normal to turn all the time.
Like when the induction cooker is put on the pot, there is a feeling of vibration and buzzing. Low efficiency and high heat. Induction cooker plus cooling fan can be started. Wireless charger power will not do large, long charging time.
Go to My Device First, in the My page of mobile service, click and select to go to "My Device". Click to view device parameters Click to select View Device parameters and proceed to the next step. Select fast charge for your phoneSelect the "Fast Charge" option to check whether the current phone supports wireless charging.
