1, if the indicator is off, please check whether the connection between the wireless charger, data cable, charger and power supply is in poor contact, it is recommended that you re-plug once. 3, please take off the mobile phone protective cover before charging because some mobile phone protective cover is too thick, or the material of the mobile phone protective cover may affect the recognition function of the mobile phone wireless charger, it is recommended that you take off the mobile phone protective coverTry again.
2. Try to replace another wireless charging base to charge the phone and determine whether the fault is the fault of the mobile phone or the wireless charger. A non-Huawei wireless charger may be incompatible with the mobile phone, resulting in abnormal wireless charging. If the preceding problems persist, you are advised to back up the phone data (third-party applications such as QQ and wechat need to be backed up separately), bring related accessories and purchase vouchers, and go to a nearby Huawei customer service center for testing.
3, first click the "Settings" option on the desktop of the phone. Then in the Settings page that opens, click on "BatteryYou're welcome? What are the pros and cons of unlimited charging? '> Why isn't wireless charging popular? What are the pros and cons of unlimited charging? 1, the disadvantage of wireless charging No protocol wireless charging , is that most of the efficiency of wireless charging is relatively low. Because relying on electromagnetic induction to charge, often the speed is relatively slow, and sometimes the phone needs to be quickly filled, then it is obvious that wireless charging is not as fast as directly using the phone to charge the data line.
2, mobile phone wireless charging because there is no need to plug frequentlyCharging cable, so the phone's data interface wear will be reduced a lot. At the same time, the coil of wireless charging of the mobile phone is not exposed to the air, which can also reduce the oxidative corrosion of the charging unit. The wired charging is often inserted and removed easily lead to wear, and the interface is exposed, which is easy to oxidation corrosion. Although wireless charging has many advantages, it is also found that there are many disadvantages in the actual use process.
3, benefit one: reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply, and then place the device that supports wireless charging on the wireless charging board. Wireless charging is still needed, thoughTo connect the power supply, but can reduce the use of data lines, to avoid a lot of loss and waste of data lines, relatively speaking, is a relatively environmentally friendly charging method. Benefit 2: high adaptation rate.
4, mobile phone wireless charging is not popular, mainly because the experience of wireless charging is very rubbish. Of course, the high price is also a very important factor. In terms of experience, mobile phone wireless charging has shortcomings. Compared with wired charging, wireless charging of mobile phones is not only slow, but also very inconvenient to use wireless charging. Slow charging speed: Since the Samsung Note 7 explosion, mobile phone wireless charging power has been castrated by manufacturersMHM.
5, low energy conversion rate: the conversion rate of wireless charging is generally about 70%. For example, a 30W wireless fast charging device, after conversion loss, the general charging efficiency is only 21W, of which 30% of the energy will be emitted in the form of heat, which is why some mobile phones will have some hot back after wireless charging. The above is the advantages and disadvantages of mobile phone wireless charging, which can be used as a reference for its non-protocol wireless charging other mobile devices.
6, advantages: The use of wireless magnetic induction charging equipment can be invisible, equipment wearLow rate, wide application range, public charging area is relatively reduced; High technical content, easy to operate, can implement relatively long distance radio energy conversion. Disadvantages: Although the equipment has high technical content, the economic cost of the equipment is higher and the maintenance cost is large; Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high.
Phone Settings. Sure there are, wireless charging has several sets of protocols, you need to see first to determine what protocol is used, commonly usedQI. Now the mobile phone is using the Qi standard, the corresponding protocol we generally say WPC protocol. It is divided into 5w, 15w and 5 to 15w. The actual company does between 9w and 12w. Others are PMA, A4WP and so on. What I do know is that A4WP is usually used for car charging.
Test with a wireless charger, which is the simplest and most direct method, put the phone on the wireless charger, if the charging is displayed, it means that the wireless charging function is not supported.
You can view the model of Apple wireless charger in the following ways: View the packaging box: such asIf you still have the original box of your Apple wireless charger, the model number is usually indicated on the label or back of the package. Check the charger itself: The model information may be printed near the case or connector of the Apple wireless charger.
Save the mobile phone manual, or the mobile phone has internal instructions, you can check whether the mobile phone has the introduction of wireless charging function in the function parameters. The simplest and most direct method is to put the phone on the wireless charger and display the charging, which means that it has the wireless charging function, and the reverse is not supported. The principle of the wireless charger is electromagnetic induction technology, which only needs to be installed in the mobile phoneWire charging of the receiving coil will do.
Wireless charging is characterized by no limitation of the charging line, affected by the nickel-metal hydride battery, this battery has memory, the best way to use is to reach the best state of the battery after charging. The wireless charging method does not have the bondage of the line, and takes it with each charge, reducing the complexity of plugging and unplugging the data cable. This is more conducive to maintaining the best performance of the lithium battery, without waiting until it is used up and then charging it, and without charging it too full.
Versatility: Having a common standard is one of the advantages of wireless charging. Wired charging ports abound, including Android's Micro USB, Type-C and Apple's Lightning interface, different phones need different interfaces. The wireless charger does not have to be so troublesome, and can be used to support wireless charging. At present, the standard is mainly QI wireless charging. Of course, wireless chargers also have drawbacks.
