Wireless fast charging does not hurt the battery, because fast charging is an emergency charging method, using DC charging, the voltage is generally greater than the battery voltage, need to passThe rectifier device converts alternating current into direct current, which puts higher requirements on the voltage resistance and protection of the power battery pack, so the virtual charge is actually to better protect the battery. If there is no battery technology, fast charging does have a greater damage to the battery.
Mobile phones that support the wireless fast charge protocol will not damage the phone battery when charging using the official original wireless charger. Data development: How to deal with mobile phone fever when wireless charging: It may be because the mobile phone opens high-power applications when wireless charging, such as: King of Glory, Tencent video and so on. The CPU efficiency of the phone after the application is openedIt will increase the power consumption, which will cause the phone to heat up.
The reasons for fast battery loss are more due to improper use, such as excessive use of mobile phones, the use of unstable chargers, wrong charging habits, and power-consuming operations while charging. Wireless fast charge does a better job of controlling temperature and power conversion, and the impact on the battery can be controlled as long as the quality of the device is reliable. Wireless fast charge is especially suitable for those who pursue convenience, such as busy office workers.
In theory, wireless fast charge and mobile phone fast charge, are specifically designed for mobile phones, there is no mobile phone batteryWhat harm, for this point still need to understand. However, when the user chooses a wireless charger, it is best to choose a charger that is compatible with the mobile phone, or choose a charger produced by a regular manufacturer.
Long-term use of radio charging will not affect the phone. Wireless charging is characterized by no charging line restrictions, 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.
NoneThe cable charger does no harm to the phone battery. Because the working frequency of wireless charging is now below 1M, it will not affect the signal of the mobile phone. On the contrary, wireless chargers not only reduce the use of data cables, but also make charging methods more free and safer. It is basically the same as wired charging, but the rate is lower, but the wireless charger still has a high energy conversion rate, which saves energy consumption more.
1, wireless charging and wired charging have advantages, chooseWhich is better depends on the specific use case and requirements. Advantages of wireless charging: Convenience: Wireless charging does not need to plug in or pull out the charging cable, just put the device on the charger to start charging, very convenient. Aesthetic: Wireless charging will not damage the shell design of the device, making the overall device look more beautiful.
2, wireless charger is good, convenient, safe and durable; The disadvantages are bondage, high price and low efficiency. Advantages of wireless charger: Convenient: Wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the problem caused by repeatedly plugging and unplugging the phone interfaceThe phenomenon of poor contact can better protect the mobile phone interface.
3, so the ordinary charger is faster than the wireless charger. There are already fast chargers and fast wireless chargers, but the results are the same. For example, the fast charging Samsung S8 takes 90 minutes, then the fast wireless charger takes 190 minutes, which is the result of my own actual testing.
4, hello, of course, flash charger is fast, VOOC flash charging: VOOC flash charging is the world's first mass-produced commercial fast charging scheme, compared with other fast charging schemes, the technical threshold is higher, VOOC flash charging needsA custom adapter works with the battery. OPPO customized a special adapter, battery, data cable, circuit, interface, and for this in-depth development of intelligent all-end five-level protection technology, security is impeccable.
5, the pursuit of higher portability and comfort, you can choose wireless charging; In pursuit of faster charging speed and wider application range, you can choose wired charging. The advantage of wireless charging is that it provides higher portability, which is especially suitable for wearable devices, smart home and other fields. However, the charging speed of wireless charging is relatively slow, and the distance between the charger and the device will affect the charging efficiencyA result.
1, electric field coupled wireless charging, the principle is to transmit power by coupling two groups of asymmetric dipoles along the vertical direction of the induced electric field generated. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; However, the disadvantage is that it requires a large volume of equipment and less power.
2, the first is electric field coupling charging. First of all, mobile phonesAnd there are two sets of asymmetrical electric dipoles on the 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.
3, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the power supply of the current through the coil (wireless charger powerThe coil) will generate a magnetic field, and the other unenergized coil (the electric coil on the phone side) will generate an electric current near the magnetic field, and charge the phone.
4, the principle of wireless charging is that through near-field induction, the wireless charging device conducts energy to the charging terminal device, and the terminal device converts the received energy into electrical energy and stores it in the battery of the device. The principle of energy conduction is inductive coupling, which ensures that there is no exposed conductive interface. It can not only eliminate messy transmission lines between devices, but also be safer for electronic devices such as electric toothbrushes that are often in contact with conductive media such as liquids.
5, wireless chargingThe wireless charger is a device that uses the principle of electromagnetic induction to charge a mobile phone. At the sending end and the receiving end, the wireless charger has a coil. There is an electromagnetic signal sent out in the sending single coil, and the receiving single coil can receive the electromagnetic signal sent out, and then the electromagnetic signal is converted into current, and the current enters the mobile phone, so as to achieve the effect of wireless charging.
6, now everyone uses a new way of mobile phone charging, that is wireless charging. So what is the principle of this wireless charger? Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmissionWhat's the difference between fast charging? '> What's the difference between 40w and 50w wireless fast charge?
1, charging speed Fast charge and wireless charge switching circuit : 50W wireless fast charge has a higher power output than 40W wireless fast charge, so it can provide faster charging speed. This means that when charging with 50W wireless fast charge, the charging time of the device will be shorter. Compatibility Fast charge and Wireless charge switching circuit : 50W wireless fast charge is generally compatible with a wider range of devices. It can be for support noneLine fast charging devices provide the best charging results, including charging speed and charging efficiency.
2, test environment This test environment is not the same, the result is only a reference, Huawei Mate 20Pro is used at 0% power off for charging, the entire capacity of the battery is 4300 ma; The oppo Find X Lamborghini uses 2% of the battery to charge, also off, and the entire battery capacity is 3400 mah.
3, first of all, it can quickly charge mobile phones and other devices, greatly shortening the charging time.
