Mobile phones that support the wireless fast charge protocol will not damage the phone battery when charging with the official original wireless charger. Data development: Wireless chargingHow to do when the phone is hot: It may be because the mobile phone opens a high-power application when wireless charging, such as: King of Glory, Tencent video and so on. When the app is opened, the CPU efficiency of the phone increases, increasing the power consumption, which causes the phone to heat up.
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 voltage resistance and protection of the power battery pack put forward higher requirements, so the fast charge generated virtual electricity is actually to better protect the battery. If there is no electricityP40, Mate30, Mate30 pro, etc. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed. 2, in general, wireless fast charge is a wireless charging method based on magnetic resonance, electromagnetic induction and other technologies, which eliminates the tedious operation of wired charging, and brings users a more convenient and efficient charging experience. Its wide application and continuous technological development indicate that wireless fast charging will become the mainstream way of charging electronic devices in the future.
3, wireless fast charge is the use of electromagnetic induction principle, there is a coil in the sending and receiving end, the sending end of the coil connected to the wired power supply to generate electromagnetic signal, the receiving end of the coil induction of the sending end of the electromagnetic signal to generate current to charge the battery, can be simply understood as a transformer without magnetic core. Compared with wired, wireless charging has less loss to the battery, and wireless charging technology is more convenient and has lower charging heat.
4, w wireless fast charge refers to the wireless fast charge technology power reached 50W. Almost all 50W wireless chargers can be completed in less than 50 minutesThe entire charging process of a large capacity battery of around 00mAh. That's about the same speed as most wired fast charges today.
5, wireless fast charge is actually a function, is the short for wireless charging function, but also represents the wireless charger. This charger can not be connected to the socket, very convenient. With the function of fast charging, directly do not need the data cable to charge the phone, only need the user to put the phone near the wireless charger can be charged directly. The following is a detailed example to introduce this wireless charging method.
6, can achieve no power contact design, to avoid electric shockDanger. Disadvantages of mobile phone wireless charger: slow charging speed, low charging efficiency. Compared with the current wireless charging speed of wired is not fast, wired has high power and high current fast charging, and even 40W fast charging has appeared; However, the wireless fast charge is still in 5W, 10w low power. The cost of wireless charging is relatively high, and the phone and charger need to have wireless coils to charge.
1, advantages: non-contact, no wire, mobile. Disadvantages: short distance,Low power and poor efficiency. Low efficiency: energy storage and transmission efficiency is less than real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power.
2, advantages: the use of wireless magnetic induction charging equipment can be invisible, the equipment wear rate is low, the application range is wide, the 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.
3, the shortcomings of mobile phone wireless charging although the technical content of the equipment is high, the economic cost of the equipment is high, 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. As the distance and power of wireless charging devices increase, the loss of idle work will be greater.
4, 3, better interface durability Mobile phone wireless charging because there is no need to frequently plug and unplug the charging cable, so the data interface wear of the mobile phone 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. While wired chargingFrequent insertion and removal is easy to cause wear, and the interface is exposed, which is easy to oxidation corrosion.
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.
However, wireless fast charging does not directly lead to shorter battery life. Battery life is affected by a variety of factors, 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.
In theory, wireless fast charging and mobile phone fast charging, are forMobile phones are specially designed, and there is no harm to the mobile phone battery, which still needs to be understood. 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.
Unqualified third-party power adapters and data connection cables do not have overvoltage and overcurrent protection, which may cause unstable charging power and battery damage. The official recommendation is 0 ° C ~35 ° C is the ideal working environment for iPhone, too high or too low temperature will have a certain impact on the phone battery.
First, due to fast chargingThe charging voltage and current are larger than that of slow charging, so to the extent that the battery is damaged, fast charging is definitely more damaged. However, in actual use, this damage is actually negligible, so there is no particularly big difference between the two. Maybe everyone will be fooled by the gimmick of fast charging, thinking that this fast charging means ultra-high current and ultra-high voltage.
Fast charging does not hurt the battery, but frequent fast charging does hurt the battery compared to slow charging. The acceleration of battery cell polarization is generally the diffusion of Li inside the electrode during the charging process of lithium-ion batteriesThe migration rate is smaller than that of the electrolyte, and the internal diffusion of the electrode is the control step of the diffusion rate of Li.
