1, wireless fast charge does not hurt the battery, because fast charge is an emergency charging method, using DC charging, the voltage is generally greater than the battery voltage, the need to convert alternating current into direct current through the rectifier device, the power battery pack voltage resistance and protection put forward higher requirements, so fast charge virtual electricity is actually to better protect the battery. If there is no batteryIf the technology exists, fast charging does have a greater damage to the battery.
2, the reason for too fast battery loss is more due to improper use, such as excessive use of mobile phones, the use of unstable chargers, wrong charging habits, and power consumption operations when 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.
3, however, wireless fast charging does not directly lead to reduced battery life. Battery life depends on a variety of factorsImpact, lithium batteries have no memory effect, frequent charging, power off does not affect. What can really damage a battery are wrong charging habits, high temperatures, and substandard charging equipment. For example, the 40W wireless flash charging technology used by OPPO Ace2 takes into account charging efficiency and safety through series dual cell and air-cooled heat dissipation technology.
4, the mobile phone that supports the wireless fast charge protocol will not damage the mobile phone battery when charging using the official original wireless charger. Data development: How to do when the mobile phone heats up when wireless charging: It may be because the mobile phone opens a high-power application when wireless charging, such as: KingHonor, Tencent video, etc. When the app is opened, the CPU efficiency of the phone increases, increasing the power consumption, which causes the phone to heat up.
5, conclusion: long-term use of the iPhone's MagSafe wireless charging has little impact on battery life, but the heat dissipation problem and charger choice is crucial. Concerns about wireless charging, especially the potential damage to the iPhone's battery, are actually not as rumored. Apple's MagSafe technology is based on the Qi wireless charging standard, which itself has evolved to support 30W fast charges. Apple's improvement is to improve the charge through the magnet designElectrical efficiency, rather than changing battery technology.
1, wireless charging mobile phones are: Huawei MateRS, Huawei MateRS Porsche version built-in 4000mAh battery, support SuperCharge25W super fast charge, it is also Huawei's first wireless charging mobile phone, support 10W wireless charging function.
2, Huawei Mate 60 series, such as Mate 60 and Mate 60 Pro, not only support wireless chargingIt also has efficient wireless fast charging functions, such as Mate 60 supporting 50W wireless fast charging, which can quickly charge the mobile phone in a short time. In addition, the series of mobile phones also support wireless reverse charging, which can be used for other devices that support wireless charging, such as Bluetooth headphones, smart watches and other emergency charging.
3, Huawei Mate20PRO in 2018 only Huawei Mate20Pro has reverse wireless charging function, to know that in the past year to reach 15W wireless fast charging is also very great. A year before Samsung, Huawei's phones support innovative wireless reverse charging technology..
Wireless charging means providing electrical power to electronic devices wirelessly. Wireless charging is a modern technology that does not require a traditional physical cable connection to charge electronic devices. The basic principle is to use electromagnetic induction or radio waves to transmit energy. This technology uses a charging dock or charger to wirelessly sense the device to transfer power. There are many ways to implement the specific principles and technologies of wireless charging.
Wireless charging, also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction,That is, inductive coupling, in which the power supply device (charger) transmits energy to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
Wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the device that uses electricity. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.
Wireless charging refers to the technology of providing electrical energy to electronic devices through wireless technology. Wireless charging mainly relies on wirelessInduction technology enables the transfer of energy. With the rapid development of electronic technology, the traditional wired charging method has gradually failed to meet the needs of users due to its problems such as inconvenient insertion and removal and limited device location. The emergence of wireless charging technology has solved these problems.
2, wireless charging methods are 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 current of the power supply through the coil (wireless charger power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charge the mobile phoneElectricity.
3, the principle of mobile phone wireless charging Wireless charging mainly uses electromagnetic induction, magnetic field resonance, radio waves and electric field coupling and other ways, mobile phones use electromagnetic induction. For example, when the power current passes through the wireless charger's power supply coil, a magnetic field will be generated, and the mobile phone's electric coil will generate current when it contacts the magnetic field, achieving wireless charging.
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,No exposed conductive interface is guaranteed. 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 charging is more convenient, do not need a mobile phone interface can be charged; The use scenario of wireless charging has been expanded, and fragmented charging is easier to achieve. Secondly, because of the working principle, wireless charging can realize the design of no power contact and avoid the danger of electric shock. Disadvantages of mobile phone wireless charger: slow charging speed, low charging efficiency.
