Very simple wireless charge can not be charged , directly plug in the mobile phone to try to know is true or false, because the real 40 watt wireless charger charging quickly, false can not charge.
If combined with HUAWEI 40 W wired charger and corresponding data cable, HUAWEI Mate 30 series, HUAWEI P40 Pro can provide a maximum of 27 W wireless charging power. Knowledge Introduction Wireless charger is the use of electromagnetic induction principle for charging equipment,The principle is similar to that of a transformer.
Generally speaking, at least 20% to 15% of the richness should be left. So use 40 watts. At least you need a charger of about 50 watts. Otherwise, it is easy to burn out because the charger is too small. This brings security risks. If the traffic is too large. Easy to waste energy.
According to my understanding of the charger, the power consumption of the charger must be greater than or equal to the power consumption of the device, but if the charger power exceeds the power consumption required by the device, the device will not accelerate charging. Therefore, if the maximum power of Huawei wireless charger is 40W, while chargingThe power of the head is 66W, which cannot achieve 40W fast charging, but may cause safety problems such as overheating of the charger.
Huawei positive wireless charging usage Wireless charging failure : Put the wireless charger on a horizontal surface, connect the power supply Wireless charging failure ; Place the phone/tablet that needs to be charged in the center of the wireless charger; After a few seconds, there will be a "drop" sound, indicating the start of charging.
Because the input power and output power are different, wireless charging conversion efficiency. Replace the charging position and eliminate the intermittent failure caused by poor socket contact. If conditions permit, replace the standby charger for testing. Or send the repair test to boot charging, such as the mobile phone is equipped with a third-party plug-in such as charging doctor, it is recommended to uninstall the test.
3, check whether the use of the original charger. If not, please replace the original charger and try again. Try replacing another power socket. If the above operation is invalid, please bring the purchase invoice, repair card and machine to Samsung service center for inspection.
4, if other mobile phones can normally wireless charging, indicating that the wireless charger isOk, the phone is faulty, please contact the local official after-sales service, by the after-sales help to solve.
5, please check whether the back center of the phone is placed in the center of the wireless charging board. When there are inclusions between the mobile phone and the wireless charging pad, it may not be able to charge normally. Please check the back of the phone. If the protective phone cover used is too thick may hinder wireless charging, it is recommended to remove the phone cover and try to recharge. Please use the original Samsung charger. If you use a non-original charger, you may not be able to charge normally.
6, wired charging and wireless charging have failed, this may be a mobile phoneSomething's wrong with the charge control circuit. This problem needs to be checked and repaired by professionals. It is recommended that you send it to a professional repair shop for inspection and repair.
1. The reasons are as follows: The wireless charge cannot be charged : Click the button in the notification bar to turn on the wireless backcharge. The device to be charged needs to be placed in the right position in the center of the back cover wireless charge . The charged device must support standard Qi wireless charging protocol (for example, AppleWatch is a non-QI protocol wireless charging device can not be charged wireless charging device, can not be charged through wireless backcharging function). There should be no metal ornaments or foreign objects between the phone and the device being charged. 2, very simple, directly plug in the mobile phone to try to know is true or false, because the real 40 watt wireless charger charging quickly, false can not charge.
3, at present, some special mobile phones can be charged with wireless chargers, but as far as the current technology is concerned, the charging efficiency is similar to that of wired chargingElectrical appliances can not be compared, and many wireless chargers are immature technology, charging will make the phone unusually hot. Is the radiation value of wireless charger really larger than that of mobile phone Wireless charge can not be charged ? The staff of Dajiaoting branch of Beijing Telecom business Hall tested this. The staff took out a high-sensitivity radiation meter.
4, turn off Bluetooth and GPS: Bluetooth and GPS will also consume the battery, when you do not need to use them, it is usually best to keep in the off state, but also to turn it off when charging. Don't use USB ports: USB in computers and carsThe current output of the interface is very small, usually only 0.5A, and now the standard charging current of many mobile phones is 1A or even higher, plus the current is unstable, so it is much slower to charge.
The causes are as follows: In the notification bar, click the button to enable wireless reverse charging. 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.
Apple mobile phone can not be charged for a variety of reasons, such as the data cable and charging port contact problems, poor contact will also lead toIt won't charge. The data cable does not match, Apple's data cable must be certified by Apple to charge, the solution is as follows: Method 1: Because we are used to putting the phone in the pocket, the charging interface at the bottom of the phone is easy to enter the gray, which causes the interface to have poor contact with the power cord plug.
Take iPhone13 as an example, Apple mobile phone wireless charging may be caused by network problems, try to restore all Settings to try. Divided into 3 steps, the steps are as follows: 1 Enter the Settings General! --1 Step 1 Go to the Settings general tape step 1, Step 2 style -- Open the phone Settings diagramClick on General Options.
There is a problem with the charger or charging cable, and there is a problem with the phone battery. Faulty charger or charging cable: Make sure you are using an Apple certified charger and charging cable and check for damage or wear. Mobile phone battery problems: Mobile phone battery has been aging or damaged, will also cause wireless charging can not work properly, the battery needs to be replaced.
