1, wireless charging efficiency is related to power, the greater the general power generated by the greater the magnetic field range, the closer the distance is the better the efficiency, and the closer the receiving coil and the sending coil, the higher the energy conversion efficiency, according to the size of the distance power efficiency from 100% to 0%. If the distance is greater than 10 cm, the conversion efficiency is only about 60%, which isThe transmitted power is 1000W, and the received power is only 600W.
2, wireless charging transmission, receiving module component specifications, the distance between the coil, the interval material material will have an impact on the charging efficiency, there are a lot of wireless charger program related information available for query, your wireless charging program for what purpose, different technical solutions charging efficiency is very different.
3. GND is ground. The common negative electrode. This stuff improves efficiency. One, coil material. With two-wire structure, the effective conductive area decreases due to the skin effect of high frequency conduction. So it can be usedMultistrand (insulated) winding coil. Three use low voltage drop diodes. Fourth, the electromagnetic wave is attenuated by the square of the distance, so the closer the distance, the higher the transmission efficiency.
1, from the mobile phone itself, there is also a system to adjust the control circuit inside the mobile phone, which can play a protective role in some overcurrent and overvoltage. In the same way, the data cable is also like this, high-quality charging cable can play a charging role, and poor quality charging cable will cause handsThe machine charge is damaged.
2, this is the mobile phone in the use of high energy consumption applications, mobile phone background running too many applications, mobile phone function opened too much or mobile phone hardware problems caused. Temporarily use applications with high energy consumption. Close the application running in the background of the phone. Turn off functions you don't need on your phone. Mi 11 charging speed: from 1% to 55% in 15 minutes.
3, place the phone on the charger Finally, place your Mi 11 on the charger, make sure that the two fit tightly. If the words "Charging" appear on the screen, wireless charging is started. Don't forget the charger's electricityFoot, or the car charger itself has product quality problems. If the car charger clamping force is insufficient, it can be replaced with a suitable car charger, and if it is the quality problem of the car charger's own product, it should contact the car charger business to carry out after-sales service.
The principle of the car wireless charging base is magnetic field charging, the closer to the middle area, the better the magnetic field strength, if in the edge position, the magnetic field is weak, and even can not activate the mobile phone wireless charging function, resulting in intermittent, or can not charge. So please try to put the phone in the middle position when charging, or change a larger phone case, add some decorative pieces, etc., to ensure that the phone is inSomewhere in the middle. It should be all right. I hope this answer will help you.
The back bracket may cause the distance from the wireless charger is too large or sliding, charging instability affects the wireless charging speed of several major factors: power plug power, power cord, wireless charger power, mobile phone wireless charging receiving power, mobile phone case, mobile phone bracket.
Millet mobile phone has a special situation, the phone charger is not configured with the phone,It needs to be purchased separately, but many people for budget considerations, they did not buy a special millet charging head, but use its wireless charging slow his charger head to mention, because it is not the original configuration, resulting in an extended charging time wireless charging slow .
From the mobile phone itself, there is also a system to adjust the control circuit inside the mobile phone, which can play a protective role in over-current and over-voltage. In the same way, the data cable is also like this, high-quality charging cable can play a charging role, and inferior charging cable will be madeCell phone charging damaged.
Low charging efficiency Since it is for mobile phone charging, the speed of charging is of course the first, even if you can do "wireless" in the application way, but for the most basic requirements of charging speed can not be reached, then the experience will probably be a discount.
1, in order to ensure the quiet sleep environment, 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 chargeElectrical power, charging speed is slower than the rest of the day. Huawei this 50w 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 restriction is the most uncomfortable.
2, Huawei 50w vertical wireless charger to the night charge is particularly slow. This is to ensure that the sleeping environment is quiet, it will automatically enter the silent charging state, during this period, the mobile phone charging board intelligently adjusts the wireless charging power, and the charging speed is slower than the rest of the day. It usually slows down automatically after 9 p.mSilent charging, normal speed after 7:00 a.m.
3. If you use a Huawei mobile phone and the charging speed is slow, try the following methods: 1. Use the standard charger and the charger of different brands of data cable. The principle of fast charging is different.
2, in order to extend the life of the battery, if the battery overheats, the system may limit charging when the power reaches 80%. When the temperature drops, the iPhone charges again. If your iPhone is hot, try moving your iPhone and charger to a cooler location. When connected to USB, the iPhone does not charge wirelessly at the same time.
3, you want to ask PWhy is the wireless charging speed of hone5 slow? The following: Low charger power: Using a low power charger, the charging speed will be slow. It is recommended to use a high quality, high power charger to improve the charging speed. The charging cable is faulty: The charging cable is disconnected or damaged, which may slow down the charging speed. You are advised to check the charging cable to ensure that it is properly connected.
