Center of the back of the phone. According to the information on Xiaomi's official website, the wireless charging ring is located in the center of the back of the Xiaomi 14pro, and the Xiaomi 14pro has 120W Xiaomi Surging wired second charge, 50W Xiaomi Surging wireless second charge, and wireless backcharge. Because of the small energy loss in the transmission process wireless charging mobile phone back cover , the transmission efficiency is high wireless charging mobile phone back cover , so as to ensure that the load can be normal endurance. However, the design of the glass shell rear screen can effectively reduce the loss of energy transmission and reduce the generation of heat Wireless charger cell phone back cover , and the energy can be better transmitted by communicating the two coils Wireless charger cell phone back cover > To ensure that electronic devices will not generate excessive heat energy when charging the mobile phone and mobile phone battery damage Wireless charging mobile phone back cover ; And the electrical conductivity of the glass is almost zero, which means that too much heat will not be generated in the process of wireless charging. Signal transmission. Apple is the rear glass is to improve the signal of the device, the metal shell will have a certain impact on the signal of the device. Today's mobile phones have a common appearance, that is, the back cover of the mobile phone is all made of glass design, and from high-end to low-end, many models have adopted this design. Compared withOther materials, glass signals better, metal will reflect the signal, causing problems with signal reception. In addition, the glass body has a lot of advantages, such as not easy to occur paint, corrosion and other problems, and tempered glass will not occur after the shell scratch problem, with the development and growth of the glass body, now can be converted into a variety of beautiful colors, to promote the mobile phone shell more and more beautiful. 1, metal screenShield electromagnetic waves, wireless charging is through electromagnetic waves to transfer energy, and a big disadvantage of metal is "excellent electromagnetic shielding." If the phone uses a metal back cover, it will inevitably affect the normal work of wireless charging, and the wireless charging function will lose its meaning. 2, wearing a mobile phone case will not affect charging, if the ambient temperature is high, it may affect heat dissipation, at this time you can take off the mobile phone case and charge. The standard protective shell for wireless charging mobile phones has no impact on wireless charging. If other protective shells are used, it is recommended to remove the protective shell before wireless charging the mobile phone. Note: The metal case will charge wirelessThe signal interferes, affecting the wireless charging function. 3, wearing the original protective case can better protect the mobile phone, will not cause adverse effects on the mobile phone. If the metal protective case is used, the signal reception of the mobile phone may be affected. 4, in fact, many mobile phone metal shell material for aluminum alloy, although aluminum alloy is difficult to produce eddy current heating, but will block the spread of electromagnetic waves, that wireless charging is useless...... In summary, whether from the perspective of antenna design, or from the addition of more functions today, the metal back shell has become a "hindrance." 5.Now mobile phone manufacturers will gradually abandon the use of metal design? This problem may have the following reasons: A big drawback of the first metal back cover is the relatively large impact on the signal. The previous metal back cover and back shell have added non-metal signal overflow belts, which look very inconsistent. The metal rear cover limits the efficiency of wireless charging. 1, Apple 13pro can not wireless charging reason: the phone case used by the phone is too thick, resulting in wireless chargingThe electrical function cannot be used normally. Consider removing the protective case on your phone when using it. Wireless charging is done without pointing the phone at the corresponding area and adjusting the area where the phone is located. Wireless charger is not the official original charger, resulting in the mobile phone identification device is not successful. Replace the official original charger for charging operation. 2, if the phone can not be charged, it is recommended that you try the following methods: Use the original charger to connect to the home power supply to charge. Replace the power socket Try or replace a data cable with a charger to charge. For mobile phones with removable batteries, you can also try: 1) It is recommended to shut down and remove the battery,Use a cotton swab to clean the battery contacts and the contact points where the phone connects to the battery. Reinstall the battery and try charging it again. 3, may be because the mobile phone protection shell is too thick caused by the connection failure, the solution at this time is: take down the mobile phone shell, re-wireless charging can be. It may be that the wireless charger is not the official original charger, resulting in the failure of the mobile phone identification device. At this time, the treatment method is: replace the official original charger for charging operation. It may be that the wireless charger is in poor contact, resulting in the failure to perform normal wireless charging operations. 4, the reason is as follows: In the notification bar drop-down clickButton to enable wireless backcharging. The charged device needs to be placed in the correct position in the center of the rear cover. The device to be charged needs to support the standard Qi wireless charging protocol (for example, AppleWatch is a non-Qi wireless charging device, which cannot be charged through the wireless backcharging function). There should be no metal ornaments or foreign objects between the phone and the device being charged. 5, if there are obstacles between the charging board and the phone, such as keys, coins, etc., it will affect the charging effect, and they need to be removed. The phone case is too thick thick protective case may affect the charging effect, try to take down the phone case and then charge. chargingThe device is not the original charger may make the wireless charging ineffective, remember to use the original Samsung charger. 6, Method 1: Because we are used to putting the mobile phone in the pocket, the charging interface at the bottom of the mobile phone is easy to enter the ash, which causes the interface to have poor contact with the power cord plug. Therefore, when the mobile phone cannot be charged, please first check whether the interface at the bottom of the mobile phone is blocked by foreign bodies. If there is no problem with the power interface of the phone, then we can use the replacement method to replace the charger and power cord that we usually use. Depending on your situation. Wireless charging Wireless charging mobile phone back cover , the mobile phone standard protection case has no effect on wireless charging Wireless charging mobile phone back cover , If you use the wireless charging mobile phone back cover his protective shell Wireless charging mobile phone back cover , it is recommended to remove the protective shell and then wireless charging the mobile phone. Apple 13 If in noneLine charging is not necessary to take down the phone case, but it should be noted here that the wireless can be charged through the phone case, but the coil type magnetic charging must take off the phone case to charge wireless charging phone back cover , but now it is also perfectly solved by the business, You can buy a case with a magnetic magnet. To charge the iphone, it is not necessary to take a magnetic protection case, if for the sake of safety performance, it can be taken, but most of the problems will not happen, if you have to buy the relatively formal mobile phone case isIt's okay. Why can't the back cover of a wireless charging mobile phone be metal?
