The principle of wireless charging of mobile phones in a general sense is the process of converting electrical energy into a magnetic field, which is transmitted through the air, and then converted into electrical energy. The principle of wireless charging is somewhat similar to the understanding of the transformer in the popular sense, the transformer magnetic field coupling circuit is a magnetic conductor, the wireless charging magnetic field coupling circuit is air, and the magnetic medium is different.Wireless charging in the industry generally has four major technologies: magnetic induction technology, magnetic resonance technology, microwave technology and electric field coupling technology.
The first is field-coupled charging. First, there are two sets of asymmetrical electric dipoles on the phone and charging device. When they are close together, they produce a coupling phenomenon and achieve the transmission of current. The transfer efficiency is good, but there are distance restrictions, and large capacity charging stations are required. The second type is magnetic resonance charging, which is different from the above electric field. This method generates electrical energy through the resonance of the same frequency magnetic field generated by the resonators at both ends.
Electric field coupled wireless charging, the principle is by coupling two groups of non in a vertical direction>
2, power plug power, wireless charger power, mobile phone wireless charging receiving power power plug power/wireless charger power/mobile phone wireless charging receiving power, these three key points are mutually complementary and mutually restrictive relationship, the final actual power is the smallest of these three items for the actual charging power.
3, when the temperature is too high, the charging power will automatically decrease. All versions of Mi 11 charging temperature control is particularly strict, the temperature reached 36 degrees began to slow down 40%, normal to 9000ma, mobile phone temperature above 36 degrees is only about 5000 ma. The Mi 11Pro battery is equipped with a large battery capacity of 5000mAh, which supports 67W fast charging, 67W wireless charging, and 10W reverse charging.
4, millet 11 broken charging slowed down, it may be the use of non-original charger. It is recommended to use the original charger, in addition, you need to charge in a low temperature environment, if you charge in a high temperature environment, the phone in the self-protection function will automatically reduce the charging speed to prevent overheating.
5, this is the mobile phone in the use of high energy consumption applications, mobile phone background running too many applications, mobile phone functions openedMore 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.
6, millet 9 two charging methods measured: wired fast charge, half an hour to 61%. 0-100 takes only 63 minutes. Wireless flash charge to 55% in half an hour. 0-100 takes 74 minutes.
Charge using a data cable connectionHead and charging base, and then plug the charging head into the power supply. Place the charging base on the table, with the phone's screen facing up in the center of the charging base. After the phone is placed on the charging base for a few seconds, there is a "drip" sound, indicating the start of charging. If you use the super fast charging head and Super fast charging base, the charging base will use the super fast charging mode to charge the phone.
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 Phone Fast Charge Select""Fast charge" option to check whether the current phone supports wireless charging. Wireless charging Finally, after confirming, put the phone on the wireless charger, the charging prompt will be displayed, and it is OK.
Place the charger on a horizontal surface or other location suggested by the manufacturer. Place the phone on the charger with the screen facing up. For best performance, place the phone in the center of the charger or in the location recommended by the manufacturer. The phone should make a "drip" sound after placing it on the wireless charger for a few seconds, indicating the start of charging. When charging starts, you should see Fast Charge passing Super Fast Charge in your phone's status barThe sign of...
Confirm that your iQOO phone supports wireless charging. Please note that only some iQOO phone models support this feature. Open your phone's Settings menu. You can swipe your finger on the home screen to find the "Settings" icon and tap into it. In the Settings menu, find the "Power Management" option and click on it. On the Power Management page, you can see the Wireless Charging option. Click to access this option.
1, confirm that your iQOO mobile phone supports wireless charging function. Please note that only some iQOO phone models support this feature. Open your phone's Settings menu. You can swipe your finger on the home screen to find the "Settings" icon and tap into it. In the Settings menu, find the "Power Management" option and click on it. On the Power Management page, you can see the Wireless Charging option. Click to access this option.
2, connect the phone's standard charger and data cable to the wireless charger, and then put the phone on the wireless charger baseIn the middle position, wireless charging can be realized, the indicator light will have a breathing effect, and it will be extinguished after 5 seconds, plug and play, convenient and quick.
3, first, open the phone and click to enter the Settings. 2, then, enter the setting interface, click the battery to enter 3, finally, in the battery interface, open the wireless reverse charging switch.
